+ Allow to override build date with SOURCE_DATE_EPOCH.
+
+commit 68682879ce9704606fb0d46734dfaba4966de9b5
+Author: Bernhard M. Wiedemann <bwiedemann@suse.de>
+Date: Sun Aug 9 14:10:55 2020 +0200
+
+ Allow to override build date with SOURCE_DATE_EPOCH
+
+ in order to make builds reproducible.
+ See https://reproducible-builds.org/ for why this is good
+ and https://reproducible-builds.org/specs/source-date-epoch/
+ for the definition of this variable.
+
+ Also consistently use ISO 8601 date format to be understood everywhere.
+ This also avoids %B and %h that are locale-dependent.
+
+ Also use UTC/gmtime to be independent of timezone.
+
+ Also rewrite the shell `date` calls into perl to avoid
+ trouble with the different date command implementations.
+
+ This PR was done while working on reproducible builds for openSUSE.

+
+ Add higher-order normal computations for degenerate Bézier triangles.
+
+ - Depending on the magnitude of the computed normal, higher order
+ derivatives are used as needed.
+ - Normals are now computed relative to the central sub-triangle, which
+ aligns better with the symmetry and (seems to) avoid degeneracies.

+
+ Move the computation of normals to reduce redundant computation.
+
+ Before, normals were computed as triangles were pushed to the indices
+ array. However, this caused the same normals to be needlessly recomputed
+ (up to six times, half of which we cannot avoid without a major
+ overhaul).
+ By moving the normal calculation to occur at the same time as the
+ vertices are added to the buffer, most of the redundant normal
+ computations have been removed.

+
+ On C99-compliant machines with 64 bit integers, use compact items for
+ the virtual machine, relying on Asymptote's internal type checking (compile
+ with -DCOMPACT=0 to re-enable the type_info data field). This change required
+ restricting T[] array(int n, T value, int depth=intMax) to 0, 1, or 2
+ dimensional arrays.

+
+ In cases like 2D graphs where only an approximate picture size estimate is
+ available, adjust the transform so that the fitted frame meets the
+ size specification. The pic.scale() routine (which scales the resulting
+ frame, including fonts and true size objects) can enforce even better
+ compliance in such cases, but should not normally be required.

+
+ Results of type overhaul:
+ - venv now uses a hashtable to quickly look up variable of a specific type
+ - initializers and casts are now functions in the environment
+ - matching arguments to signatures handled by application class
+ - (side-effects of) expressions are evaulated left-to-right
+ - exp::trans(e, target) split into transToType (which implicitly casts) and
+ transToType (which doesn't)
+ - added keyword and rest arguments
+ - added formal class to types

+Date: Fri Dec 3 08:31:00 2004 -0600
+
+ Reworked dvips and gs pdfwrite interface: do a post-bbox correction rather than

+
+ Fixed filename extension detection so that filenames containing ./ and ../
+ work correctly.

+Compiling Asymptote from a Source Release
+=========================================
+
+To compile and install Asymptote version x.xx from a source release:
+
+gunzip asymptote-x.xx.src.tgz
+tar -xf asymptote-x.xx.src.tar
+cd asymptote-x.xx
+./configure
+make all
+make install
+
+The last command requires root privileges. To install without root privileges
+you should change the first line to
+
+./configure --prefix=$HOME/asymptote
+
+If you get errors from a broken texinfo or pdftex installation, simply put
+https://asymptote.sourceforge.io/asymptote.pdf
+in the doc directory and repeat the commands make all and make install.
+
+For a list of configure options, type
+
+configure --help
+
+See also the generic configure instructions below.
+
+Compiling Asymptote from Git Developmental Source Code
+=============================================================
+
+To compile from Git developmental source code:
+
+git clone http://github.com/vectorgraphics/asymptote
+cd asymptote
+./autogen.sh
+./configure
+make all
+make install
+
+Optional packages:
+
+* Fast Fourier Transform library
+ http://www.fftw.org/
+
+ Version requirement >= 3.0
+
+* The GNU Scientific Library for numerical analysis:
+ http://www.gnu.org/software/gsl/
+
+*****************************************
+Generic Configure Instructions (advanced)
+*****************************************
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+ It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring. (Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.)
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+ The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'. You only need
+`configure.ac' if you want to change it or regenerate `configure' using
+a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system. If you're
+ using `csh' on an old version of System V, you might need to type
+ `sh ./configure' instead to prevent `csh' from trying to execute
+ `configure' itself.
+
+ Running `configure' takes awhile. While running, it prints some
+ messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation.
+
+ 5. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+Compilers and Options
+=====================
+
+Some systems require unusual options for compilation or linking that the
+`configure' script does not know about. Run `./configure --help' for
+details on some of the pertinent environment variables.
+
+ You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment. Here
+is an example:
+
+ ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
+
+ *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+ If you have to use a `make' that does not support the `VPATH'
+variable, you have to compile the package for one architecture at a
+time in the source code directory. After you have installed the
+package for one architecture, use `make distclean' before reconfiguring
+for another architecture.
+
+Installation Names
+==================
+
+By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc. You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX'.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+There may be some features `configure' cannot figure out automatically,
+but needs to determine by the type of machine the package will run on.
+Usually, assuming the package is built to be run on the _same_
+architectures, `configure' can figure that out, but if it prints a
+message saying it cannot guess the machine type, give it the
+`--build=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+ CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+ OS KERNEL-OS
+
+ See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+ If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+ If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+If you want to set default values for `configure' scripts to share, you
+can create a site shell script called `config.site' that gives default
+values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+Variables not defined in a site shell script can be set in the
+environment passed to `configure'. However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost. In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'. For example:
+
+ ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script). Here is a another example:
+
+ /bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+Here the `CONFIG_SHELL=/bin/bash' operand causes subsequent
+configuration-related scripts to be executed by `/bin/bash'.
+
+`configure' Invocation
+======================
+
+`configure' recognizes the following options to control how it operates.
+
+`--help'
+`-h'
+ Print a summary of the options to `configure', and exit.
+
+`--version'
+`-V'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`--cache-file=FILE'
+ Enable the cache: use and save the results of the tests in FILE,
+ traditionally `config.cache'. FILE defaults to `/dev/null' to
+ disable caching.
+
+`--config-cache'
+`-C'
+ Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`configure' also accepts some other options. Run
+`configure --help' for more details.

+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+ To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights. Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received. You must make sure that they, too, receive
+or can get the source code. And you must show them these terms so they
+know their rights.
+
+ Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+ For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software. For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+ Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so. This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software. The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable. Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products. If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+ Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary. To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ TERMS AND CONDITIONS
+
+ 0. Definitions.
+
+ "This License" refers to version 3 of the GNU General Public License.
+
+ "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+ "The Program" refers to any copyrightable work licensed under this
+License. Each licensee is addressed as "you". "Licensees" and
+"recipients" may be individuals or organizations.
+
+ To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy. The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+ A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+ To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy. Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+ To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies. Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+ An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License. If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+ 1. Source Code.
+
+ The "source code" for a work means the preferred form of the work
+for making modifications to it. "Object code" means any non-source
+form of a work.
+
+ A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+ The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form. A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+ The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities. However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work. For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+ The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+ The Corresponding Source for a work in source code form is that
+same work.
+
+ 2. Basic Permissions.
+
+ All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met. This License explicitly affirms your unlimited
+permission to run the unmodified Program. The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work. This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+ You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force. You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright. Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+ Conveying under any other circumstances is permitted solely under
+the conditions stated below. Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+ 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+ No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+ When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+ 4. Conveying Verbatim Copies.
+
+ You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+ You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+ 5. Conveying Modified Source Versions.
+
+ You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+ a) The work must carry prominent notices stating that you modified
+ it, and giving a relevant date.
+
+ b) The work must carry prominent notices stating that it is
+ released under this License and any conditions added under section
+ 7. This requirement modifies the requirement in section 4 to
+ "keep intact all notices".
+
+ c) You must license the entire work, as a whole, under this
+ License to anyone who comes into possession of a copy. This
+ License will therefore apply, along with any applicable section 7
+ additional terms, to the whole of the work, and all its parts,
+ regardless of how they are packaged. This License gives no
+ permission to license the work in any other way, but it does not
+ invalidate such permission if you have separately received it.
+
+ d) If the work has interactive user interfaces, each must display
+ Appropriate Legal Notices; however, if the Program has interactive
+ interfaces that do not display Appropriate Legal Notices, your
+ work need not make them do so.
+
+ A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit. Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+ 6. Conveying Non-Source Forms.
+
+ You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+ a) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by the
+ Corresponding Source fixed on a durable physical medium
+ customarily used for software interchange.
+
+ b) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by a
+ written offer, valid for at least three years and valid for as
+ long as you offer spare parts or customer support for that product
+ model, to give anyone who possesses the object code either (1) a
+ copy of the Corresponding Source for all the software in the
+ product that is covered by this License, on a durable physical
+ medium customarily used for software interchange, for a price no
+ more than your reasonable cost of physically performing this
+ conveying of source, or (2) access to copy the
+ Corresponding Source from a network server at no charge.
+
+ c) Convey individual copies of the object code with a copy of the
+ written offer to provide the Corresponding Source. This
+ alternative is allowed only occasionally and noncommercially, and
+ only if you received the object code with such an offer, in accord
+ with subsection 6b.
+
+ d) Convey the object code by offering access from a designated
+ place (gratis or for a charge), and offer equivalent access to the
+ Corresponding Source in the same way through the same place at no
+ further charge. You need not require recipients to copy the
+ Corresponding Source along with the object code. If the place to
+ copy the object code is a network server, the Corresponding Source
+ may be on a different server (operated by you or a third party)
+ that supports equivalent copying facilities, provided you maintain
+ clear directions next to the object code saying where to find the
+ Corresponding Source. Regardless of what server hosts the
+ Corresponding Source, you remain obligated to ensure that it is
+ available for as long as needed to satisfy these requirements.
+
+ e) Convey the object code using peer-to-peer transmission, provided
+ you inform other peers where the object code and Corresponding
+ Source of the work are being offered to the general public at no
+ charge under subsection 6d.
+
+ A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+ A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling. In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage. For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product. A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+ "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source. The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+ If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information. But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+ The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed. Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+ Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+ 7. Additional Terms.
+
+ "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law. If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+ When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it. (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.) You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+ Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+ a) Disclaiming warranty or limiting liability differently from the
+ terms of sections 15 and 16 of this License; or
+
+ b) Requiring preservation of specified reasonable legal notices or
+ author attributions in that material or in the Appropriate Legal
+ Notices displayed by works containing it; or
+
+ c) Prohibiting misrepresentation of the origin of that material, or
+ requiring that modified versions of such material be marked in
+ reasonable ways as different from the original version; or
+
+ d) Limiting the use for publicity purposes of names of licensors or
+ authors of the material; or
+
+ e) Declining to grant rights under trademark law for use of some
+ trade names, trademarks, or service marks; or
+
+ f) Requiring indemnification of licensors and authors of that
+ material by anyone who conveys the material (or modified versions of
+ it) with contractual assumptions of liability to the recipient, for
+ any liability that these contractual assumptions directly impose on
+ those licensors and authors.
+
+ All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10. If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term. If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+ If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+ Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+ 8. Termination.
+
+ You may not propagate or modify a covered work except as expressly
+provided under this License. Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+ However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+ Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+ 9. Acceptance Not Required for Having Copies.
+
+ You are not required to accept this License in order to receive or
+run a copy of the Program. Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance. However,
+nothing other than this License grants you permission to propagate or
+modify any covered work. These actions infringe copyright if you do
+not accept this License. Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+ 10. Automatic Licensing of Downstream Recipients.
+
+ Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License. You are not responsible
+for enforcing compliance by third parties with this License.
+
+ An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations. If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+ You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License. For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+ 11. Patents.
+
+ A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based. The
+work thus licensed is called the contributor's "contributor version".
+
+ A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version. For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+ Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+ In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement). To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+ If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients. "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+ If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+ A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License. You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+ Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+ 12. No Surrender of Others' Freedom.
+
+ If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all. For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+ 13. Use with the GNU Affero General Public License.
+
+ Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work. The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+ 14. Revised Versions of this License.
+
+ The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation. If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+ If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+ Later license versions may give you additional or different
+permissions. However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+ 15. Disclaimer of Warranty.
+
+ THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. Limitation of Liability.
+
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+ 17. Interpretation of Sections 15 and 16.
+
+ If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software: you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation, either version 3 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program. If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+ If the program does terminal interaction, make it output a short

+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+ This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+ 0. Additional Definitions.
+
+ As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+ "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+ An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+ A "Combined Work" is a work produced by combining or linking an
+Application with the Library. The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+ The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+ The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+ 1. Exception to Section 3 of the GNU GPL.
+
+ You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+ 2. Conveying Modified Versions.
+
+ If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+ a) under this License, provided that you make a good faith effort to
+ ensure that, in the event an Application does not supply the
+ function or data, the facility still operates, and performs
+ whatever part of its purpose remains meaningful, or
+
+ b) under the GNU GPL, with none of the additional permissions of
+ this License applicable to that copy.
+
+ 3. Object Code Incorporating Material from Library Header Files.
+
+ The object code form of an Application may incorporate material from
+a header file that is part of the Library. You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+ a) Give prominent notice with each copy of the object code that the
+ Library is used in it and that the Library and its use are
+ covered by this License.
+
+ b) Accompany the object code with a copy of the GNU GPL and this license
+ document.
+
+ 4. Combined Works.
+
+ You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+ a) Give prominent notice with each copy of the Combined Work that
+ the Library is used in it and that the Library and its use are
+ covered by this License.
+
+ b) Accompany the Combined Work with a copy of the GNU GPL and this license
+ document.
+
+ c) For a Combined Work that displays copyright notices during
+ execution, include the copyright notice for the Library among
+ these notices, as well as a reference directing the user to the
+ copies of the GNU GPL and this license document.
+
+ d) Do one of the following:
+
+ 0) Convey the Minimal Corresponding Source under the terms of this
+ License, and the Corresponding Application Code in a form
+ suitable for, and under terms that permit, the user to
+ recombine or relink the Application with a modified version of
+ the Linked Version to produce a modified Combined Work, in the
+ manner specified by section 6 of the GNU GPL for conveying
+ Corresponding Source.
+
+ 1) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (a) uses at run time
+ a copy of the Library already present on the user's computer
+ system, and (b) will operate properly with a modified version
+ of the Library that is interface-compatible with the Linked
+ Version.
+
+ e) Provide Installation Information, but only if you would otherwise
+ be required to provide such information under section 6 of the
+ GNU GPL, and only to the extent that such information is
+ necessary to install and execute a modified version of the
+ Combined Work produced by recombining or relinking the
+ Application with a modified version of the Linked Version. (If
+ you use option 4d0, the Installation Information must accompany
+ the Minimal Corresponding Source and Corresponding Application
+ Code. If you use option 4d1, you must provide the Installation
+ Information in the manner specified by section 6 of the GNU GPL
+ for conveying Corresponding Source.)
+
+ 5. Combined Libraries.
+
+ You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+ a) Accompany the combined library with a copy of the same work based
+ on the Library, uncombined with any other library facilities,
+ conveyed under the terms of this License.
+
+ b) Give prominent notice with the combined library that part of it
+ is a work based on the Library, and explaining where to find the
+ accompanying uncombined form of the same work.
+
+ 6. Revised Versions of the GNU Lesser General Public License.
+
+ The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+ If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+ ASYMPTOTE
+ Copyright 2004-20 Andy Hammerlindl, John Bowman, and Tom Prince
+
+Asymptote is a powerful descriptive vector graphics language for technical
+drawing, inspired by MetaPost but with an improved C++-like
+syntax. Asymptote provides for figures the same high-quality level of
+typesetting that LaTeX does for scientific text.
+
+Installation instructions, documentation, binaries, and source code are
+available at:
+
+https://asymptote.sourceforge.io
+
+Bugs/Patches/Feature Requests can be submitted to
+
+https://github.com/vectorgraphics/asymptote/issues
+
+Questions and comments should be sent to the Asymptote Forum:
+
+https://sourceforge.net/p/asymptote/discussion/409349

+surface normals were fixed. The octant1, hemisphere, and sphere
+surfaces were replaced by nondegenerate versions that render faster.
+The unitcone, unitfrustum, and DefaultHead3 arrowhead were simplified.
+A robust and more efficient tube routine was implemented;
+the PRC tube primitive was removed. WebGL compression was achieved by
+implementing sphere, disk, cylinder, and tube primitives in the AsyGL library.
+Patches are now split in both directions only when required.
+If the GNU Readline library is unavailable, the Editline library

+vector editor) for external vector EPS graphics (embedded images, PDF, PNG,
+and JPG formats are not yet supported). Building under CYGWIN with X11 is
+supported again. The --version option lists both enabled and disabled features.

+latexusage-* and latexusage.aux when switching between latex and pdflatex
+usage was documented.
+
+Release Notes for Version 1.53
+

+the surface of revolution constructor was fixed. Support for
+three-dimensional dimension bars was added; PenMargin3 and DotMargin3 were
+fixed. The argument put=Above (put=Below) should now be replaced by

+updated to use lightgray instead of the new default surface color (black).
+The sphere animation example was updated to work with the new skeleton
+structure in the solids module.
+
+Release Notes for Version 1.45
+

+was improved. New arrowhead3 types HookHead3 and TeXHead3 were added. The
+default surface color is now black. New surface and path constructors were
+added. Secure options can now be queried as read-only settings.

+directly with Asymptote's own fast OpenGL-based renderer. The implicit
+casts from 3D to 2D objects were removed (in favour of call explicit calls
+to project). A path[][] texpath(string s) routine was added to convert
+string into the paths that TeX would fill. Add boolean stroke parameter was
+added for shading (and clipping to) stroked paths. The Circle and Arc
+routines were fixed. Autoscaling of graph axes limits is now disabled by
+default. A path3 path3(path p, triple plane(pair)=XYplane) constructor was
+added; the path3 routines were moved to C++ code. Optimized and robust
+versions of the intersection, windingnumber, inside, and surface extrema
+routines were implemented. The lighting routines were replaced by the
+OpenGL model. Each Asymptote process once again uses a separate
+currentpen. A segmentation fault and an incorrect parameter in the
+Delaunay triangulation routine were fixed. This major overhaul of the
+three-dimensional graphics has necessitated a few backwards
+incompatibilities. The most significant change involves filldraw:
+
+filldraw(polygon(5),red);
+
+should be replaced by
+
+draw(surface(polygon(5)),red);
+
+Also, the solids module has been improved so that
+
+revolution a=revolution(O--X+Z,Z);
+a.filldraw(red,blue);
+
+is now more sensibly written as
+
+revolution a=revolution(O--X+Z,Z);
+draw(surface(a),red);
+draw(a,blue);

+bidirectional pipe are now caught. In inline latex mode, TeX headers are
+now output only when needed. A bug in the cancellation of text addition in
+xasy was fixed. The sticky bit is no longer set when creating the ~/.asy
+directory. The documentation and FAQ were updated.
+The dot(real[] a, real[] b) routine now returns the dot product of the
+vectors a and b; this introduced a backwards incompatibility:
+dot(x,y) should now be replaced with dot(pairs(x,y)).
+
+Release Notes for Version 1.41
+
+Python-style array slices were added. The array virtual field A.keys
+returns the indices of initialized entries. The concat routine can now

+was added. History lines are now stored immediately after input (as well
+at exit, after stifling). Support for the HSV colorspace was added.

+renaming animate.asy to animation.asy (PDF animations still need to import
+animate.asy). Transparency groups are now respected by xasy.
+TeX diagnostics were improved. An obsolete function for drawing boxes on
+pictures was removed in favour of draw(Label,box).

+replaced with a unitsize function. The seconds() function now works
+portably. Minor bugs in inside() were fixed; a winding number routine was
+added. The movie bounding box is set to the largest bounding box of all
+pictures. Portable high-quality embedded PDF movies are now supported, as
+well as portable external movies. An embedded U3D example was added.
+Alignment positioning transformation was fixed; a Rotate(pair) and a
+string(real x) routine was added. Flowchart routines and the labelbox and
+advection examples now work with pictures as well as frames.
+An add(picture pic=currentpicture, drawer d) wrapper was added; a picture
+rescaling bug was fixed. Tex error handling was improved. Optional bounds
+arguments were added to verbatim postscript and tex commands. Writing to
+only the local directory is allowed unless the -global (or -unsafe) option
+is specified. A final backslash continues a line on the interactive prompt;
+a new multiline option is convenient for cutting and pasting code in
+interactive mode. Clipping now sets the true size coordinates to 0. Memory
+usage was reduced. The documentation was updated, including a description
+of how to produce Debian binaries from RPM binaries.

+pdflatex, tex, and pdftex are supported. Separate xunitsize and
+yunitsize scalings are allowed. Graph axis bound communication was added
+to allow axes with ticks and unextended axes to be called on an empty
+picture. Path labels are drawn after the path (to support UnFill).
+Filltype definitions were standardized; a Draw filltype was added (for
+drawing a bounding box around a label). New filloutside routines were
+added. Images can be drawn for irregular mesh contours and two-dimensional
+pen arrays. Landscape slides automatically enable PDF autorotate option.

+improved. Bounding box calculations now account for label scaling.
+A special case of the Step calculation in graph.asy was fixed. The function
+scroll(int) was changed to a setting; a quit (q) option was added to the
+scroll facility. To avoid an unwanted ghostscript window, gswin32c (rather
+than gswin32) is used by default for producing pdf files under MSDOS.
+
+Release Notes for Version 1.11
+
+The defaultformat string is used again for graph tick labelling commands
+instead of an empty format string. A workaround for the broken

+improved. A slope fields package was added. The arrow size limiting code
+was fixed. Some bugs in makepen were fixed. Image and shading functions
+now respect the -gray, -rgb, -cmyk, and -bw options. Date arithmetic routines
+were added. Several small bugs in the graph routines were fixed. Custom
+three-dimensional projections can now be easily constructed.
+
+The public keyword is now the default permission modifer. A new keyword,

+structure in which they are defined (previous this was the default behaviour).
+A user-transparent work around for the backwards-incompatible command-line
+options of gv-3.6.1 was implemented. Various configuration problems were
+addressed to better support the Asymptote rpm for the Fedora Core Extras
+project. A cputime() function was added.
+

+The default pdf viewer for MacOS is now "open". The -u option can now be
+specified multiple times on the command line. Optional x and y margin
+arguments were added to Fill. A reverse video option was added to
+slide.asy; titlepage and title by default call newslide, unless the
+currentpicture is empty. An argument was added to newslide to allow
+stepping to be turned off for that slide. The slidedemo example now
+generates any required eps files. A segmentation fault in eval was fixed.
+
+Release Notes for Version 1.05
+
+Shaded and skeletal representations of surfaces of rotation were
+implemented. New oblique projections were added and bugs in the 3D graph
+routines were fixed. An argument reversal in one of the add routines was

+postscript patterns. Configuration problems were fixed. The editor
+customization files asy.vim and asy-mode.el were moved to the Asymptote
+system directory. Stepping of slide presentations can now be enabled from
+the command line. Many new tests were implemented. The examples were moved
+to the examples subdirectory of the documentation directory.
+RPM files are now released.
+
+Release Notes for Version 1.04
+
+A convenient presentation slide package was developed. The misalignment of
+TeX and PostScript layers was fixed by giving includegraphics the exact
+bounding box. The overall bounding box was also fixed. The tension atleast
+command and the clipping of remote labels by unfill near the frame boundary
+were fixed. Permission checking for types was added. The new point-like
+truepoint function uses the actual current picture size. Locale support,
+the ', I, and F format specifiers, and custom pagewidth and pageheight
+settings were added. A Ticks specifier draws ticks on both sides of the path;
+format="%" also suppress tick labels for logarithmic axis.
+The linetype adjustment to the arclength was improved and can now be
+optionally disabled. Color names were systematized, including texcolors
+and x11colors. A general purpose user command-line option accepts arbitrary
+Asymptote code as a string. All duplicate path points in three.asy are now
+removed. A convenient fixedscaling picture sizing routine was added.
+Selected special functions from the GNU scientific library, DESTDIR support,
+and a Python module to access Asymptote commands were added.
+The legend skip is now based on the actual legend entry height, not the
+fontsize. A backwards incompatibility was introduced in attach, add, and
+legends (add and attach take arguments in the same order as label):
+
+attach(point(E),legend(20E),UnFill) -> attach(legend(),point(E),20E,UnFill).
+
+Release Notes for Version 1.03
+
+Support was added for compiling under gcc-4.1.0. A memory leak in
+interactive mode was fixed. A procedure for using CJK fonts was documented.
+The return type of the three-dimensional intersectionpoint routines was

+specified plane was added, along with a solid geometry package with
+routines to draw cylinders. New xaxis(triple,real), min(guide3[]), and
+max(guide3[]) convenience functions were added. A Degrees function like
+degrees(pair), except that it returns 0 for a (0,0) argument rather than
+generating an error, was added. Interactive mode (without command-line
+editing or history) now works even in the absence of the GNU readline
+library. An upper limit (100000) on the number of calls to intersectcubics
+per cubic segment was imposed on the intersection routines. The
+documentation was updated.
+
+Release Notes for Version 1.02
+
+Lighting was implemented for surfaces described by functions and matrices.
+A bug in the positioning of axis labels was fixed. The type of randMax was
+fixed. Configuration and diagnostics were improved; the "dir" setting in
+configuration files is respected. Under MSDOS, the configuration file is
+now %USERPROFILE%/.asy/config.asy; configuration settings now work as
+documented. On UNIX systems, installation can optionally be performed
+without root privileges. Errors thrown by the parser while reading the
+configuration file are now handled gracefully. The patches to pstoedit
+were removed since they are now included in pstoedit-3.44.

+longer crop data by default. For consistency, the "includegraphics"
+labeling function was renamed to "graphic".
+
+Release Notes for Version 0.99
+
+A bus error and compilation error under MacOS X were fixed. If -debug is
+set, execution continues after the first error. The "make check" code was
+fixed. The contributed MacOS X binary site is now mentioned in the
+documentation.
+
+Release Notes for Version 0.98
+
+Command-line options and configuration variables were reorganized into an
+Asymptote settings module, allowing default values to be set in
+~/.asy/config.asy (~/.asy/options is obsolete). Command-line options
+can be negated by prepending -no to the option name. Type-dependent
+function and record operators are now added to the parent record.
+Execution stops after the first error in a runnable. Two- and
+three-dimensional array min/max functions for all ordered builtin types
+were implemented. Comments are now allowed within 3d data blocks. The base
+file plain.asy was split into many subfiles. The currentpen nib is
+respected. Warning messages are suppressed when shipping out an empty
+picture. The tick computation was fixed when xaxis and yaxis are called
+with explicit limits. The -t option was removed as it is no longer needed
+for generating inline tex files. Machine constants are now implemented as
+variables rather than functions.

+to any polygonal (possibly nonconvex) cyclic path. A unitsize argument was
+added to the shipout command. Three-dimensional lighting effects were
+added and illustrated with the Gouraud shading of a sphere. The MidArrow
+attribute was fixed. Builtin functions now have named arguments. Brackets
+are now part of the quote syntax. The write command was generalized
+to allow writing a list of vectors as columns. Drawing to standard output
+now works even when there are no labels. The -noView command was replace
+by -nView or -no View. Several segmentation faults were fixed. Custom axis
+types were documented.
+
+Release Notes for Version 0.95
+
+A memory leak was fixed; garbage collection messages are now suppressed
+unless the -d option is given. In interactive mode, a reset keyword was
+implemented to restore the environment, except for the scroll setting.
+The interactive input command now does an automatic reset. A link was
+added to the GNU readline library documentation for customizing interactive
+key bindings. A hang in scroll mode on an end-of-file condition was
+fixed. To reduce LaTeX memory usage, the scalebox macro is used only where
+required. A legend problem was fixed. The documentation was updated.
+
+Release Notes for Version 0.94
+
+A label bug arising from a conflict between some versions of the LaTeX
+pstricks and graphicx packages was fixed. Embedded LaTeX files are always
+run in quiet (-noView) mode. Frame loading issues with imported types
+(for example, with the triangle SAS constructor in the geometry module) was
+fixed. The command import graph is now an abbreviation for access graph;
+unravel graph.
+
+Release Notes for Version 0.93
+
+The import scheme was completely redesigned, with new keywords access,
+unravel, from, and include. A true (rather than emulated) interactive mode
+and runtime imports have been implemented. The default pdf browser is now
+acroread; the pdf fuzz workaround for gv was removed. The tension3 and
+curl3 keywords were re-added; a surface graph routine for matrices was
+implemented. Problems with csv mode were fixed. The function defaultpen()
+was renamed to resetdefaultpen(). Integer division via quotient(int,int)
+is now consistent with the modulo (%) operator. Checks for integer
+overflow and erf, erfc, and gamma functions were added. More descriptive
+names latticeshade, axialshade, radialshade, and gouraudshade for the
+shading routines were chosen. Horizontal and vertical label scaling was
+implemented. Default command line style-parameters can now be stored in
+~/.asy/options. The interactive history file is now ~/.asy/history by
+default unless -localhistory is specified. Outputting to standard output
+via "-o -" is now allowed.
+
+
+Release Notes for Version 0.92
+
+Clipping now clips labels and all layers of a picture, not just the most
+recent one. A bug in precontrol and postcontrol was fixed. A ticklabel bug
+and precision errors at +/-1e-4 were fixed. An example of a "broken" x
+axis was added. A dot product now requires explicit pair arguments.
+The implicit cast from real to pen was removed. Straight flags are now
+preserved when using a path as part of a guide. An UnFill filltype was
+added for clipping underneath labels and legends. A struct marker was added
+to support arbitrary marker locations. Directories are no longer stripped
+from explicit output filenames.
+
+A function inside was implemented to test whether a point is inside a
+cyclic path. The routines inside, quadratic solver, and intersect in
+math.asy were replaced by internal C++ routines. A robust real cubic root
+solver was added. A floating point exception in complex powers when base is
+zero was fixed. Colinearity checks were added to the leastsquares routine.
+
+The interface to plane was changed to return a representation of the plane
+through point O with normal cross(u,v). The routine intersectionpoint was
+moved to plain.asy and a 3d version was added to three.asy. We now draw
+over existing TeX layers when doing 3d hidden surface removal. A 3d aspect
+ratio can now be specified. A gui() function and MSWindows support for xasy
+was added; this will require renaming "gui(" to "GUI(" in any existing .gui
+files. The dir argument of picture.fit() was moved to add(frame,pair)
+and attach(frame,pair):
+
+add(pic.fit(E)) -> add(pic.fit(),E).
+
+Release Notes for Version 0.91
+
+Fixed GUI transforms: grouping should not depend on deconstruct flag.
+
+Release Notes for Version 0.90
+
+Default function arguments are now evaluated in the scope where the
+function is defined, not in the scope of the caller. The depth handling
+of deferred TeX labels was fixed. The positioning of 3d axes labels was
+improved; an example showing tick and axis label rotation was added.
+A minimum value of fuzz in the intersect routines is enforced to prevent
+infinite loops. An error in the man page regarding the -t option was
+fixed. The write function was generalized to handle an arbitrary number of
+data values.
+
+Release Notes for Version 0.89
+
+The processing of GUI files was fixed. User-specified ticks now work also
+with logarithmic axes. The arguments of LeftTicks and RightTicks were
+standardized; it is now possible to include a general string(real) routine
+to typeset each label. Logarithmic axes ranges of less than a decade are no
+longer upscaled when autoscaling is disabled. All references to the
+mailing list were removed from the documentation since the forum is now
+used in its place. The temporary included PostScript file suffix was
+renamed from "ps" to "eps".
+
+Release Notes for Version 0.88
+
+The graph routines were overhauled to support both two- and three-
+dimensional axes, partitioning them uniformly in tick value space,
+not with respect to arclength. An empty format string is treated as
+defaultformat. A fuzz parameter was added to the intersect routines;
+these routines now work for points. Data file comments were implemented.
+The perpendicular routine now uses an alignment argument; scale(pair) was
+removed. An option was added to asymptote.sty to make all LaTeX symbols
+visible, along with a second optional string to Label for providing a size
+estimate for undefined labels. Numerous small bugs were fixed; the
+pstoedit patch was updated. The installation and instructions were
+improved. An environment variable for every external command was added.
+
+The argument order of the axes routines was standardized; a call like
+xaxis(min,max,"$x$",red,Bottom,LeftTicks);
+should now be written
+xaxis("$x$",Bottom,min,max,red,LeftTicks);
+
+Release Notes for Version 0.87
+
+This release implements general hidden surface removal using a binary space
+partition and adds three-dimensional versions of the standard path
+functions (arclength, subpath, intersect, etc.), along with circle and arc
+functions. Hidden surfaces in regular mesh surface plots now are properly
+handled from any camera location. The arclength rather than the length is
+used for determining default label position on paths; Relative(real) and
+Relative(pair) functions were added for labelling paths relative to the
+total arclength and local path direction. Structure constructors and
+operators == and != were implemented and documented. The permissions of
+static functions within structures was fixed. A pen argument to filltype
+Fill to specify an interior pen distinct from the boundary pen was added.
+For convenience, array push members now return the pushed element.
+A missing shift in Label.out(frame) was added. The feynman module was
+updated to include a new function texshipout; MidArrow was moved to
+plain.asy. The optional position arguments of BeginArrow and related
+functions were fixed. A numerically robust quadratic equation solver was
+added.
+
+Release Notes for Version 0.86
+
+Fixed make man problems.
+
+Release Notes for Version 0.85
+
+A fully three-dimensional, rotationally invariant, generalization of the
+two-dimensional MetaPost path construction algorithms has been
+implemented. A tridiagonal solver was added. Adobe's automatic rotation of
+PDF files was disabled. Cyclic indices are now allowed only on arrays
+having the virtual cyclic flag set to true. The bug fix in simplex was
+generalized. An online help option was added to interactive mode; exit is
+now a synonym for quit. Microsoft Windows resource fields and an icon were
+added. ASYMPTOTE_DIR can now be a list of directories.
+
+Since some files were moved in this release, Microsoft users may wish to
+first uninstall the previous release to avoid duplicate files.
+
+Release Notes for Version 0.84
+
+This release ports Asymptote to the Microsoft Windows operating system; an
+executable file is distributed. Label parameters are now in a structure
+called Label, to which strings are implicitly cast, and which can be
+rotated and shifted with a transform. Automatic sizing under picture
+transformation was fixed. A bug in the simplex method was fixed. Lattice
+and Gouraud shading were added. An array append method, virtual transform
+components, and transform 6-tuple notation were added. A pen and filltype
+were added to legend. The 2d graph and palette code were cleaned up.
+An extend option was added to draw ticks across the graph for producing a
+grid. Problems with nullguide3 were fixed, the arguments of 3d rotate were
+swapped, and 3d reflections were added. A spurious papersize comment
+inserted by newer versions of dvips was removed. Pstoedit support was updated.
+
+This release introduces a few minor backward incompatibilities. Here is a
+summary of the main changes:
+
+draw("text",(0,0)--(1,1),1.0) -> draw(Label("text",1.0),(0,0)--(1,1))
+label("text",90,(0,0)) -> label(rotate(90)*"text",(0,0))
+labeldot("text",(0,0)) -> dot("text",(0,0))
+labeldot((0,0)) -> dot(Label,(0,0))
+labelbox(2mm,2mm,"text",(0,0)) -> box(Label("text",(0,0)),2mm,2mm)
+xaxis("$x$",0.5) -> xaxis(Label("$x$",0.5))
+labelxtick(1) -> xtick(Label,1)
+
+Release Notes for Version 0.83
+
+This release extends Asymptote to three dimensions. A triple type (which
+replaces the old vector type in math.asy) and a guide3 type were added,
+along with the 3D projection routines in three.asy. Three-dimensional
+arrays can now be read in line mode, using blank lines as block
+delimiters. An array pop function was added. Math mode ($ delimiters) were
+moved to within the "defaultformat" string, to allow use of non-math mode
+fonts in tick labels (by overriding the default format). A pticklabel
+option for drawing tick labels with a different pen was added. Routines
+labelxtick and labelytick were added, and the tick size and shift in xtick
+were fixed. The autoscaling of unextended axes was fixed. The xline and
+yline routines were renamed to xequals and yequals, Dot was renamed to dot,
+Cross was renamed to cross, the function "Angle(pair)" was renamed to
+"degrees(pair)", and a "Degrees(pair)" function was added to math.asy. The
+Metapost --- operator and the replacement :: for the MetaPost ... operator
+were implemented. A segmentation fault involving controls points with
+direction specifiers and a bug in "string font(pen)" were fixed. Tensions
+in straight sections of paths are now handled as in MetaPost. The -l option
+was reimplemented.
+
+Release Notes for Version 0.82
+
+Initializers for structures and general cast operators can be specified.
+Functions can be called with named (keyword) arguments, in any order.
+Rest arguments are supported. Size and aspect ratio arguments, which may
+be specified with "size", were removed from "shipout". The tick routines
+were standardized; custom tick locations and arrows on axes were implemented.
+The default frame initializer nullframe was renamed to newframe. A segmentation
+fault in the file garbage collection code and an optimization-related bug
+in fill were fixed.
+
+Unlike in the C and C++ languages, an assignment in a function argument is
+now interpreted as an assignment to a parameter of the same name in the
+function signature, not within the local scope. The command-line option -d
+may be used to check Asymptote code for cases where a named function
+argument may be mistaken for a local assignment.
+
+Release Notes for Version 0.81
+
+A guide solver bug was fixed, allowing the construction of graphs with a single
+data point. Compilation under g++-4.0.0 is now supported.
+
+Release Notes for Version 0.80
+
+A segmentation fault on the alpha (cxx) and mac platforms was fixed.
+All members of the picture structure are now deep copied.
+The latest Boehm garbage collector (version 6.5) is used by default.
+
+Release Notes for Version 0.79
+
+Types are now cached to speed up parsing. All outstanding garbage collection
+issues were addressed. The autoscaling of scaled axes was fixed.
+Another example of a secondary axis was added to the documentation.
+A Pythagorean tree example illustrates picture transforms.
+
+Release Notes for Version 0.78
+
+A binary search routine was added for sorted arrays. The handling of NAN
+values was fixed. The "checkaxis" test in graph.asy was improved.
+A problem with implicit closing of files was fixed. Minor changes were made
+to support compilation under Cygwin. A workaround for the garbage
+collection warning about repeated allocation of very large
+blocks was introduced, along with other miscellaneous garbage collection
+updates. A configuration option was added to request use of a (slower,
+multi-theaded) system version of the Boehm garbage collector.
+
+Release Notes for Version 0.77
+
+Integer arguments are now converted to real values before dividing and a real
+quotient is returned. The "quotient(int, int)" function returns the integer
+part of that result. Garbage collection has been implemented to fix memory
+leaks. A knot solving bug was fixed. Pen "plabel" vs. "p" issues were
+addressed. The eval function was renamed to map and the new eval(string)
+function was documented. The concat function can be used to concatenate two
+arrays. Complex exponential and logarithmic functions were added. The new
+function reltime can be used to compute the label position argument for draw.
+A new geometry module includes a triangle structure and functions to draw
+interior arcs of triangles and perpendicular symbols.
+
+Release Notes for Version 0.76
+
+Installation has been simplified by removing the last remaining dependency
+on the boost header files. A "plabel" argument was added to "draw" to allow
+labels and legends to use a different pen than the curve itself. The pen
+arguments in the axes routines were rearranged to be consistent with
+"draw". TeX errors in interactive mode and the TeX preamble are now
+handled properly. New functions "getstring" and "getreal" can get and
+remember user parameters. Marker frame arrays, a "Mark(int)" function,
+and "node", "value", and "slope" path computation functions were added.
+Problems with implicit scaling were addressed. The "without side-effect"
+warning was removed. An option was added to list all loaded global
+functions. The documentation of structures was improved.
+
+Release Notes for Version 0.75
+
+This release fixes a number of bugs with the new parser controller,
+including a segmentation fault with the -p option, problems with
+interactive mode, and problems reading from standard input. The graph
+module now uses a better default value of axislabelmargin for positioning
+axis labels. The put argument of the axis routines was moved to the end of
+the argument list, for consistency with draw. Convenient xline and yline
+interfaces to the axis routines were added. The definition of the
+correlation coefficient in the least squares routine was fixed, and a fit
+function was added to the 'linefit' structure. A linear interpolation (with
+endpoint extrapolation) and a binary search routine were added to math.asy.
+
+Release Notes for Version 0.74
+
+This release fixes a segmentation fault in version 0.73 and also reduces
+the default number of colors in image palettes to work around
+PostScript/PDF limitations (that can cause the manual not to print).
+
+Release Notes for Version 0.73
+
+A more efficient type-safe union was used to speed up the virtual machine
+by roughly a factor of 5. New routines "ellipse" and "labelellipse"
+were added for drawing ovals around frames and labels. The function
+"bbox(frame)" was renamed "box(frame)". These routines now prepend to
+the frame for filling with a background color; they also return the boundary
+as a guide. A workaround was added for a bug in gcc version 3.3 to
+facilitate compilation under Darwin (MacOS). Many internal coding
+improvements were made.

+%description
+Asymptote is a powerful descriptive vector graphics language for technical
+drawings, inspired by MetaPost but with an improved C++-like syntax.
+Asymptote provides for figures the same high-quality level of typesetting

+# SYNOPSIS
+#
+# AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+#
+# DESCRIPTION
+#
+# This macro figures out how to build C programs using POSIX threads. It
+# sets the PTHREAD_LIBS output variable to the threads library and linker
+# flags, and the PTHREAD_CFLAGS output variable to any special C compiler
+# flags that are needed. (The user can also force certain compiler
+# flags/libs to be tested by setting these environment variables.)
+#
+# Also sets PTHREAD_CC to any special C compiler that is needed for
+# multi-threaded programs (defaults to the value of CC otherwise). (This
+# is necessary on AIX to use the special cc_r compiler alias.)
+#
+# NOTE: You are assumed to not only compile your program with these flags,
+# but also link it with them as well. e.g. you should link with
+# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
+#
+# If you are only building threads programs, you may wish to use these
+# variables in your default LIBS, CFLAGS, and CC:
+#
+# LIBS="$PTHREAD_LIBS $LIBS"
+# CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
+# CC="$PTHREAD_CC"
+#
+# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
+# has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
+# (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
+#
+# Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
+# PTHREAD_PRIO_INHERIT symbol is defined when compiling with
+# PTHREAD_CFLAGS.
+#
+# ACTION-IF-FOUND is a list of shell commands to run if a threads library
+# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
+# is not found. If ACTION-IF-FOUND is not specified, the default action
+# will define HAVE_PTHREAD.
+#
+# Please let the authors know if this macro fails on any platform, or if
+# you have any other suggestions or comments. This macro was based on work
+# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
+# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
+# Alejandro Forero Cuervo to the autoconf macro repository. We are also
+# grateful for the helpful feedback of numerous users.

+For full functionality the `two-mode-mode' package should also be installed
+(http://www.dedasys.com/freesoftware/files/two-mode-mode.el).
+
+I. This package provides two modes:
+1- asy-mode:
+All the files with the extension '.asy' are edited in this mode, which provides the following features:
+* Syntax color highlighting;
+* Compiling and viewing current buffer with the key binding C-c C-c;
+* Moving cursor to the error by pressing the key F4.
+* Showing the available function prototypes for the command at the cursor with the key binding C-c ?
+* Compiling and viewing a TeX document linked with the current buffer (usually a document that includes the output picture).
+To link a Tex document try 'M-x asy-set-master-tex' follow by C-Return (see descriptions further of the key binding C-Return, C-S-Return, M-Return, M-S-Return etc within 2- lasy-mode)
+
+2- lasy-mode
+Editing a TeX file that contains Asymptote code is facilitated with the hybrid mode 'lasy-mode'.
+Toggle lasy-mode with M-x lasy-mode.
+In this hybrid mode the major mode is LaTeX when the cursor is in LaTeX code and becomes asy-mode when the cursor is between '\\begin{asy}' and '\\end{asy}'.
+All the features of asy-mode are provided and the key binding C-c C-c of asy-mode compiles and views only the code of the picture where the cursor is.
+Note that some keys binding are added to the LaTeX-mode-map in lasy-mode if the value of the variable lasy-extra-key is t (the default)
+.
+* C-return: compile (if the buffer/file is modified) and view the PostScript output with sequence [latex->[asy->latex]->dvips]->PSviewer
+* M-return: same with pdf output and with the sequence [pdflatex->[asy->pdflatex]]->PDFviewer
+* C-M-return: same with pdf output and with the sequence [latex->[asy->latex]->dvips->ps2pdf]->PSviewer
+* Add the Shift key to the sequence of keys to compile even if the file is not modified.
+
+II. To add a menu bar in current 'latex-mode' buffer and activate hot keys, use 'M-x asy-insinuate-latex <RET>'.
+You can automate this feature for all the 'latex-mode' buffers by inserting the five following lines in your .emacs initialization file:
+(eval-after-load \"latex\"
+ '(progn
+ ;; Add here your personal features for 'latex-mode':
+ (asy-insinuate-latex t) ;; Asymptote globally insinuates Latex.
+ ))
+
+You can access this help within Emacs by the key binding C-h f asy-mode <RET>
+
+BUGS:
+This package has been tested in:
+* Linux Debian Etch
+- GNU Emacs 22.0.50.1
+- GNU Emacs 21.4.1 (only basic errors management and basic font-lock features within lasy-mode are supported)
+* WindowsXP
+- GNU Emacs 22.0.990.1 (i386-mingw-nt5.1.2600)
+
+This package seems to work with XEmacs 21.4 but not all the features are available (in particular syntax highlighting).
+
+Report bugs to https://github.com/vectorgraphics/asymptote/issues
+
+Some variables can be customized: M-x customize-group <RET> asymptote <RET>."

+# Configuration subroutine to validate and canonicalize a configuration type.

+# CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM

+\`configure' configures Asymptote 2.69 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify

+ CXXFLAGS C++ compiler flags
+ YACC The `Yet Another Compiler Compiler' implementation to use.
+ Defaults to the first program found out of: `bison -y', `byacc',
+ `yacc'.
+ YFLAGS The list of arguments that will be passed by default to $YACC.
+ This script will default YFLAGS to the empty string to avoid a

+# SYNOPSIS
+#
+# AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+#
+# DESCRIPTION
+#
+# This macro figures out how to build C programs using POSIX threads. It
+# sets the PTHREAD_LIBS output variable to the threads library and linker
+# flags, and the PTHREAD_CFLAGS output variable to any special C compiler
+# flags that are needed. (The user can also force certain compiler
+# flags/libs to be tested by setting these environment variables.)
+#
+# Also sets PTHREAD_CC to any special C compiler that is needed for
+# multi-threaded programs (defaults to the value of CC otherwise). (This
+# is necessary on AIX to use the special cc_r compiler alias.)
+#
+# NOTE: You are assumed to not only compile your program with these flags,
+# but also link it with them as well. e.g. you should link with
+# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
+#
+# If you are only building threads programs, you may wish to use these
+# variables in your default LIBS, CFLAGS, and CC:
+#
+# LIBS="$PTHREAD_LIBS $LIBS"
+# CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
+# CC="$PTHREAD_CC"
+#
+# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
+# has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
+# (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
+#
+# Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
+# PTHREAD_PRIO_INHERIT symbol is defined when compiling with
+# PTHREAD_CFLAGS.
+#
+# ACTION-IF-FOUND is a list of shell commands to run if a threads library
+# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
+# is not found. If ACTION-IF-FOUND is not specified, the default action
+# will define HAVE_PTHREAD.
+#
+# Please let the authors know if this macro fails on any platform, or if
+# you have any other suggestions or comments. This macro was based on work
+# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
+# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
+# Alejandro Forero Cuervo to the autoconf macro repository. We are also
+# grateful for the helpful feedback of numerous users.

+# This is what autoupdate's m4 run will expand. It fires
+# the warning (with _au_warn_XXX), outputs it into the
+# updated configure.ac (with AC_DIAGNOSE), and then outputs
+# the replacement expansion.
+
+
+# This is an auxiliary macro that is also run when
+# autoupdate runs m4. It simply calls m4_warning, but
+# we need a wrapper so that each warning is emitted only
+# once. We break the quoting in m4_warning's argument in
+# order to expand this macro's arguments, not AU_DEFUN's.
+
+
+# Finally, this is the expansion that is picked up by
+# autoconf. It tells the user to run autoupdate, and
+# then outputs the replacement expansion. We do not care
+# about autoupdate's warning because that contains
+# information on what to do *after* running autoupdate.

+\section{Introduction}
+
+The package {\tt CAD.asy} provides basic pen definitions and measurement functions for simple 2D CAD drawings according to DIN 15.
+
+
+
+\section{Important rules for using this package}
+
+If a function is declared like this:
+%
+\begin{verbatim}
+void foo(int nParam1, string strParam2)
+\end{verbatim}
+%
+You may call it \verb\foo(0, 'abc');\ or \verb\foo(nParam1=0, strParam2='abc');\. The definitions of the functions in this package may change in future version: the order of the parameters may be changed, new parameters may be inserted. Therefore it is \emph{strongly recommended} always calling the functions \verb\foo(nParam1=0, strParam2='abc');\.
+
+
+
+\section{Usage}
+
+To use the capabilities of the package, import it:
+%
+\begin{verbatim}
+import CAD;
+\end{verbatim}
+%
+All functions are encapsulated in the structure \verb\sCAD\. As the pen definitions may differ depending on the size of your drawing, you have to initialize the structure before drawing:
+
+\begin{verbatim}
+static sCAD Create(int nLineGroup = 1)
+\end{verbatim}
+%
+The parameter \verb\nLineGroup\ depends on the size of your drawing. It specifies the line group to define the pens and thus the width used for the lines. The parameter has to be within the range $[0;3]$. The larger the value, the thicker the lines. Code example:
+%
+\begin{quote}\begin{verbatim}
+sCAD cad = sCAD.Create();
+\end{verbatim}\end{quote}
+
+The created variable \verb\cad\ then provides the most important pens. Available pens are:
+%
+\begin{itemize}
+\item The pens of group A:
+ \begin{itemize}
+ \item\verb\pA\
+ \item\verb\pVisibleEdge\
+ \item\verb\pVisibleContour\
+ \item\verb\pUsableWindingLength\
+ \item\verb\pSystemLine\
+ \item\verb\pDiagramCurve\
+ \item\verb\pSurfaceStructure\
+ \end{itemize}
+\item The pens of group B:
+ \begin{itemize}
+ \item\verb\pB\
+ \item\verb\pLightEdge\
+ \item\verb\pMeasureLine\
+ \item\verb\pMeasureHelpLine\
+ \item\verb\pMeasureLineBound\
+ \item\verb\pReferenceLine\
+ \item\verb\pHatch\
+ \item\verb\pWindingGround\
+ \item\verb\pDiagonalCross\
+ \item\verb\pBendLine\
+ \item\verb\pProjectionLine\
+ \item\verb\pGrid\
+ \end{itemize}
+\item The pens of group C:
+ \begin{itemize}
+ \item\verb\pC\
+ \item\verb\pFreehand\
+ \end{itemize}
+\item The pens of group E:
+ \begin{itemize}
+ \item\verb\pE\
+ \item\verb\pSurfaceTreatmentAllowed\
+ \end{itemize}
+\item The pens of group F:
+ \begin{itemize}
+ \item\verb\pF\
+ \item\verb\pInvisibleEdge\
+ \item\verb\pInvisibleContour\
+ \end{itemize}
+\item The pens of group G:
+ \begin{itemize}
+ \item\verb\pG\
+ \item\verb\pMiddleLine\
+ \item\verb\pSymmetryLine\
+ \item\verb\pPartialCircle\
+ \item\verb\pCircularHole\
+ \item\verb\pDivisionPlane\
+ \item\verb\pTransferLine\
+ \end{itemize}
+\item The pens of group J:
+ \begin{itemize}
+ \item\verb\pJ\
+ \item\verb\pCuttingPlane\
+ \item\verb\pSurfaceTreatmentRequested\
+ \end{itemize}
+\item The pens of group K:
+ \begin{itemize}
+ \item\verb\pK\
+ \item\verb\pContourBeforeDeformation\
+ \item\verb\pAdjacentPartContour\
+ \item\verb\pEndShapeRawMaterial\
+ \item\verb\pContourEligibleType\
+ \item\verb\pPartInFrontOfCuttingPlane\
+ \end{itemize}
+\end{itemize}
+%
+All pens of one group are the same. So there is no difference between the pen \verb\pA\ and the pen \verb\pVisibleEdge\. You may use the short names or the descriptive ones. The list of groups is not complete. I had no idea how to implement the pens of group D. For me, group H seems to be obsolete, and there is no group I contained in DIN 15. In the case I did something wrong translating the German names into English, the source file also contains the original German names of each pen. Whenever a drawing function does not allow you to select the pen, the right pen is selected automatically.
+
+
+
+\begin{verbatim}
+void MeasureLine(picture pic = currentpicture,
+ Label L,
+ pair pFrom,
+ pair pTo,
+ real dblLeft = 0,
+ real dblRight = 0,
+ real dblRelPosition = 0.5,
+ bool bSmallBound = false)
+\end{verbatim}
+%
+This is the basic function to draw labeled straight measurement lines. \verb\pic\ denotes the picture the line has to be drawn into, \verb\L\ is the label of the line. The pairs \verb\pFrom\ and \verb\pTo\ are the start and the end point of the distance to measure, respectively. Note, that these two points do \emph{not} refer to the start and end point of the line, as it may be longer than the measured distance.
+
+The line is extended on its left side (= the part of the line 'before' the start point) by the distance \verb\dblLeft\. On its right side (= the part of the line 'behind' the end point) it is extended by the distance \verb\dblRight\. \verb\dblLeft\ and \verb\dblRight\ must be $\leq 0$. If only one of both values is zero, it is set to the value of the other one, because according to DIN 15 it is not allowed to draw a measurement line asymmetrically. The position of the arrows indicating begin and end of the distance depends on \verb\dblLeft\ and \verb\dblRight\. If both values are 0, the measurement arrows are drawn within the measurement distance. Otherwise they are drawn outside.
+
+The parameter \verb\dblRelPosition\ refers to the relative position of the label between the start and end point. This means: The value 0 positions the label at the start point, 0.5 refers to the center between the start and the end point. Finally, the value 1 will position the label at the end point. If \verb\dblLeft\ or \verb\dblRight\ are nonzero, you may position the label at the left side of the start point ($< 0$) or at the right side of the start point ($> 1$).
+
+Usually, there is enough space to draw the measurement arrows. If you wish to use small circles instead of the arrows, set \verb\bSmallBound\ to \verb\true\.
+
+
+
+\begin{verbatim}
+real GetMeasurementBoundSize(bool bSmallBound = false)
+\end{verbatim}
+%
+Returns the size of the arrow or the small bound circle used for measurement lines.
+
+
+
+\begin{verbatim}
+guide GetMeasurementBound(bool bSmallBound = false)
+\end{verbatim}
+%
+Returns the correctly scaled guide of the arrow or the small bound circle used for measurement lines.
+
+
+
+\begin{verbatim}
+void MeasureParallel(picture pic = currentpicture,
+ Label L,
+ pair pFrom,
+ pair pTo,
+ real dblDistance,
+ // Variables from MeasureLine
+ real dblLeft = 0,
+ real dblRight = 0,
+ real dblRelPosition = 0.5,
+ bool bSmallBound = false)
+\end{verbatim}
+%
+Usually, measurement lines are placed outside the drawing with reference lines to the measured distance. \verb\pFrom\ and \verb\pTo\ denote the points of the drawing marking the begin and the end of the distance to measure, and not the begin and the end of the measurement line as in the case of the function \verb\MeasureLine\. The measurement line is placed \verb\dblDistance\ away from the distance to measure. If you would be at \verb\pFrom\ and look into the direction \verb\pTo\, it is placed on the left for positive values of \verb\dblDistance\. For negative values, it is positioned on the right. For the meaning of the other parameters see the function \verb\MeasureLine\.
+
+
+
+\begin{verbatim}
+guide MakeFreehand(pair pFrom, pair pTo,
+ real dblRelDivisionLength = 12.5,
+ real dblRelDistortion = 2.5,
+ bool bIncludeTo = true)
+\end{verbatim}
+%
+To draw a line between two points, which is not straight, but more like a freehand line, use this function. The pairs \verb\pFrom\ and \verb\pTo\ denote start and end point, respectively. \verb\dblRelDivisionLength\ is the length of the parts, the line is subdivided into. \verb\dblRelDistortion\ is the amount of distortion. Both sizes are given relative to the width of a freehand line. If \verb\bIncludeTo\ is \verb\true\, the point \verb\pTo\ is added to the path. Otherwise it is not. This may be useful for converting a guide containing more than two points to a freehand line.
+
+
+

+\section About Asymptote
+
+\question 26jun:whatisasy What is Asymptote?
+
+Asymptote is a vector graphics language designed for
+technical graphics, inspired by MetaPost but with IEEE floating-point numerics,
+native three-dimensional graphics, Grayscale/RGB/CMYK colourspaces, and a
+C++-like syntax. Unlike MetaPost, it natively supports multiple-segment paths
+(and hence regions other than simply connected ones), tiling patterns, Gouraud
+ shading, tensor patch shading, and PostScript images.
+
+\question 22jun:whereisasy How do I obtain Asymptote?
+
+Binary releases are available for Linux, MacOS X, and Microsoft Windows
+platforms, in addition to full source code, from the website
+\docref{https://asymptote.sourceforge.io/\}. Many Linux distributions
+(such as RedHat and Debian) now include an Asymptote package (check your
+distribution's documentation for further information about this).
+
+\question 28jun:beforeasking Where can I ask questions about Asymptote?
+
+If you have a question, please try to find an answer in this FAQ, in the
+extensive Asymptote documentation at
+\docref{https://asymptote.sourceforge.io/doc/\}, or search the forum:
+\docref{http://sourceforge.net/forum/forum.php?forum_id=409349\}.
+
+\question 02sep:whyasy Why was the name Asymptote chosen?
+
+Well, it isn't the perfect graphics package, but we do think it is getting there
+asymptotically...
+
+\question 02sep:whycamp In the internal Asymptote source code, what does the name \courier{camp\} refer to?
+
+That was our original tentative name for this project, which stood for
+"C's Answer to MetaPost" (the language that inspired Asymptote).
+However, we eventually decided that the name \courier{Asymptote\} better
+emphasizes the mathematical and graphical nature of this language.

+\section Questions about installation and setup
+
+\question 26jun:osx Is it possible to install Asymptote on Mac OS X?
+
+It is easy to compile Asymptote directly from the source code at
+\docref{http://sourceforge.net/project/showfiles.php?group_id=120000\}
+We recommend first upgrading to the latest GNU readline library, unless you
+don't care about interactive readline support (in which case configure will
+automatically detect and disable obsolete versions of the readline library).
+Marius Schamschula also maintains a binary package for various MacOS X
+platforms
+\docref{http://www.hmug.org/pub/MacOS_X/X/Applications/Publishing/asymptote\}.
+
+\question 26jun:osxbadCPU Why do I get the error \courier{Bad CPU type in executable\} on installing Asymptote from the MAC OS binary?
+
+This means either that you have a binary distribution for another MAC
+architecture, or (according to Marius Schamschula) that you may have a missing
+library. The simplest solution is to compile Asymptote directly from the
+official source:
+\docref{http://sourceforge.net/project/showfiles.php?group_id=120000\}.
+
+\question 04nov:brokenpdftex What do I do if I get the error: \courier{Error: pdfetex (file pdftex.cfg): cannot open config file...texinfo.tex appears to be broken\}?
+
+Simply put \docref{https://asymptote.sourceforge.io/asymptote.pdf\}
+in the directory \courier{doc\} and repeat the command \courier{make all\}.
+Or, if you don't want to build a local copy of the documentation, simply
+proceed with \courier{make install-asy\}.
+
+\question 04nov:brokentexinfo What do I do if I get the error: \courier{! Undefined control sequence. l.6 @copying\}?
+
+Either upgrade your \courier{texinfo\} package or follow one of the easy work arounds in \qref brokenpdftex.
+
+\question 27jun:latexintegration Is it possible to integrate Asymptote into LaTeX?
+
+Yes, see the example latexusage.tex. Dario Teixeira has also written a detailed
+guide on the topic. You can download it from
+\docref{http://dario.dse.nl/projects/asylatex/\}.
+
+Philippe Ivaldi has contributed an Asymptote mode for Emacs users
+\docref{https://asymptote.sourceforge.io/doc/Editing-modes.html\},
+which includes a \courier{lasy-mode\} that allows one to compile and view
+the output of one \\begin{asy}...\\end{asy} section at a time.
+
+\question 02sep:pdflatex Is it possible to integrate Asymptote into latex or pdflatex?
+
+Yes, as of version 1.14, Asymptote supports latex and pdflatex (both in
+EPS/PDF and inline mode), as illustrated by the example
+\courier{latexusage.tex\}:
+
+\verbatim
+pdflatex latexusage
+asy latexusage
+pdflatex latexusage
+\endverbatim
+
+\question 02sep:tkinterdepend Do I need the \courier{tkinter\} package to install an Asymptote rpm binary?
+
+No, you don't need \courier{tkinter\} unless you want to try out the GUI \courier{xasy\}. Try
+
+\verbatim
+rpm -Uvh --nodeps asymptote-x.xx-1.i386.rpm
+\endverbatim
+
+where \courier{x.xx\} represents the version number.
+
+\question 26jun:windir What does the path \courier{%USERPROFILE%\\.asy\\config.asy\} mean?
+
+That is the way that Microsoft Windows refers to the user profile directory.
+There's nothing really to understand here, just put your configuration
+commands in the file \courier{config.asy\} in a new folder \courier{%USERPROFILE%\\.asy\}.
+
+\question 25dec:escapechar Why do I get the error "string not terminated" when I try to set \courier{settings.dir="C:\\asymptote\\";\}?
+
+The backslash is an escape character here, so
+\courier{\\"\} is interpreted as a verbatim quotation mark, leaving the string
+without a terminating quotation mark. Fortunately, this is the
+only escaped character in double-quoted strings. A final backslash isn't
+needed here anyway, but should you really want one somewhere, you can say:
+\courier{settings.dir="C:\\asymptote"+'\\\\';\}.
+
+\question 27jun:winglobal How do I change environment variables in Microsoft Windows, for example, in order to change the default PostScript viewer?
+
+While it is easier to set the corresponding Asymptote configuration
+variable in your \courier{config.asy\} file, here is the procedure for changing
+Microsoft Windows environment variables:
+
+Click on the [Start] button
+
+* RIGHT-click on 'My Computer'
+
+* Choose 'Properties' from the popup menu
+
+* Click the 'Advanced' tab
+
+* Click the 'Environment Variables' button.
+
+\question 02sep:convert Under Microsoft Windows XP, why do I get an error like "Invalid Parameter - 432x432"?
+
+This means that ImageMagick wasn't properly installed and you are using the
+MSDOS convert program rather than the ImageMagick one. Or you may have
+installed ImageMagick but ran Asymptote from an existing MSDOS window.
+In that case, simply open a new window and try again. If that doesn't work,
+check that
+
+\verbatim
+convert --version
+\endverbatim
+
+returns something like
+
+\verbatim
+Version: ImageMagick 6.2.8 06/27/06 Q16 http://www.imagemagick.org
+\endverbatim
+
+\question 26jun:miktex Why does Asymptote freeze upon trying to draw a label with my MikTex installation under Microsoft Windows?
+
+Likely, this means that latex and dvips are not in your default path.
+Try adding the appropriate paths in your \courier{config.asy\} file,
+for example:
+
+\verbatim
+import settings;
+latex="C:\Program Files\MiKTeX 2.7\miktex\bin\latex.exe";
+dvips="C:\Program Files\MiKTeX 2.7\miktex\bin\dvips.exe";
+\endverbatim
+
+\comment #####################################################################
+
+\section Questions about paths
+
+\question 02sep:tensionsyntax Why do I get a syntax error message when I specify an integer value for the path tension?
+
+What is happening here is that
+
+\verbatim
+draw((0,0)..tension 2..(0,50)..(100,100));
+\endverbatim
+
+is read as
+
+\verbatim
+draw((0,0)..tension 2. .(0,50)..(100,100));
+\endverbatim
+
+So the first . after the two is treated as a decimal point.
+Just put a space after the integer tension value:
+
+\verbatim
+draw((0,0)..tension 2 ..(0,50)..(100,100));
+\endverbatim
+
+\question 27jun:dots Shouldn't dots always be the same size?
+
+From the documentation:
+
+"The dot command defined in the module plain draws a dot having a diameter
+equal to an explicit pen linewidth or the default linewidth magnified by
+dotfactor (6 by default)."
+
+Thus, when you use the default pen, the dot will have size 6*linewidth,
+but when you give a pen with an explicit width specified, you will
+have a dot of size linewidth. If you want the first case to behave like the
+second, you may set dotfactor=1.
+
+\comment #####################################################################
+
+\section Questions about labels
+
+\question 02sep:greek How do I get Greek letters like omega to show up in my labels?
+
+In (La)TeX, Greek letters can be obtained in math mode by prepending a
+backslash to the letter name. So for a omega symbol, use "$\\omega$". Everything
+between the dollar signs is considered to be a math formula. Uppercase Greek
+letters can be used by capitalizing the first letter of the name:
+
+\verbatim
+label("$\omega$",(0,0));
+label("$\Omega$",(20,0));
+\endverbatim
+
+\question 29jun:matlabels Can Asymptote use matrices as labels?
+
+Yes:
+\verbatim
+usepackage("amsmath");
+label("$\begin{matrix} 1 & 2 \\\ 1 & 1 \end{matrix}$",(0,0));
+\endverbatim
+
+\question 27jun:latexpackage How do I tell Asymptote to load a particular LaTeX package, like \courier{mathptmx\}?
+
+Put
+
+\verbatim
+usepackage("mathptmx");
+\endverbatim
+
+at the beginning of your file. Note: to enable the Adobe Times Roman font
+for text, you will also need to say:
+\verbatim
+defaultpen(TimesRoman());
+\endverbatim
+
+
+\question 28jun:internatfonts How can I use international fonts in Asymptote labels?
+
+See \docref{https://asymptote.sourceforge.io/doc/Pens.html\}.
+
+\question 10jul:Fourier How can I use Fourier fonts?
+
+\verbatim
+usepackage("fourier");
+defaultpen(font("T1","fut\textfamilyextension","m","n"));
+\endverbatim
+
+\question 26jun:decsep Is there any way to change the default appearance of the decimal separator, using a comma instead of a dot?
+
+Just set your locale appropriately:
+
+\verbatim
+locale("it_IT");
+usepackage("icomma");
+label(format(0.5));
+\endverbatim
+
+\question 02sep:rotatelabel How can I get a rotated label with the filled box rotated as well so that it fits the text?
+
+\verbatim
+frame f;
+label(f,"This is some text",white,Fill(blue));
+add(rotate(65)*f);
+\endverbatim
+
+
+\question 02sep:rotatelabel3D How can I rotate labels in a 3D figure?
+
+You need to first project the triple to a pair like this:
+
+\verbatim
+import three;
+size(100,100);
+
+draw(rotate(90,project(Z))*"A",O--X);
+\endverbatim
+
+\question 02sep:fixedsize How can I draw some squares and circles of a fixed size and put a label in the middle of them?
+
+Fixed-size objects should be drawn on a separate picture and then added to
+currentpicture. Here is one way (see also \docref{https://asymptote.sourceforge.io/gallery/subpictures.asy\} and \docref{https://asymptote.sourceforge.io/gallery/mosquito.asy\}):
+
+\verbatim
+real u=2cm;
+
+picture square;
+draw(square,scale(u)*shift(-0.5,-0.5)*unitsquare);
+
+picture circle;
+draw(circle,scale(0.5u)*unitcircle);
+
+void add(picture pic=currentpicture, Label L, picture object, pair z) {
+add(pic,object,z);
+label(pic,L,z);
+}
+
+add("square",square,(0,0));
+add("circle",circle,(5cm,0));
+\endverbatim
+
+\question 27jun:colorssaturation The binary operator * can be used to scale the color of a pen by a real number. Does this scaling factor have to be less than 1?
+
+The scaling factor can be greater than 1. But keep in mind that the rgb color
+components saturate at 1.
+
+Try
+\verbatim
+write(cyan); write(0.8*cyan); write(1.5*cyan);
+\endverbatim
+and you will quickly see what is going on.
+
+To get a lighter cyan you can say white+cyan,
+which yields rgb(0.5,1,1). If you want something even lighter specify the
+rgb colors directly,
+for example, rgb(0.9,1,1).
+
+Alternatively, work in cmyk colour space, which is nicer in that it handles
+saturation separately from hue:
+
+0.1*Cyan is light and 0.9*Cyan is dark.
+You can also say 0.1*cmyk(red).
+
+\question 05mar:commadecimalseparator Why is the space after the comma decimal separator in my locale so large?
+
+LaTeX is treating the comma as punctuation and not as a decimal separator.
+The solution is to load the \courier{icomma\} package near the beginning of your file:
+\verbatim
+usepackage("icomma");
+\endverbatim
+
+\question 11mar:hyperref How can I prevent \courier{texpreamble("\\usepackage[pdftex]{hyperref}")\} from changing the page size?
+
+\verbatim
+texpreamble("\usepackage[pdftex,setpagesize=false]{hyperref}");
+\endverbatim
+

+\section Questions about arrows
+
+\question 02sep:doublearrows How do I draw two arrows at arbitrary positions along a path?
+
+Assuming that at least one of the arrowheads is to be filled, you can do this:
+
+\verbatim
+size(200);
+path g = (0,0)..(1,3)..(3,0);
+draw(g,Arrow(Relative(0.9)));
+add(arrow(g,invisible,FillDraw(black),Relative(0.5)));
+add(arrow(reverse(g),invisible,FillDraw(white,black),Relative(0.9)));
+\endverbatim
+
+If both of the arrowheads are to be drawn with filltype NoFill,
+one will need to create a specialized version of the arrow routine in
+\courier{plain_arrows.asy\}:
+
+\verbatim
+void arrow(frame f, arrowhead arrowhead=DefaultHead,
+ path g, pen p=currentpen, real size=0,
+ real angle=arrowangle, filltype filltype=arrowhead.defaultfilltype,
+ position position=EndPoint, bool forwards=true,
+ margin margin=NoMargin, bool center=false);
+\endverbatim
+
+\question 02sep:reversearrow How do I reverse the direction of an arrowhead?
+
+Simply reverse the direction of the path.
+
+\verbatim
+path g=((0,0)--(5cm,0));
+draw(reverse(g),Arrow(Relative(0.55)));
+\endverbatim
+
+\question 02sep:reversearrow How do I change the size of all arrows?
+
+To override the arrowsize you can give every Arrow drawing attribute a real
+size argument. If you want to do this globally, you can override the
+pen-dependent arrowsize function like this:
+
+\verbatim
+DefaultHead.size=new real(pen p=currentpen) {return 2mm;};
+\endverbatim
+
+\question 26jun:arrowhead Can I create other arrowhead styles?
+
+Yes, you can build custom arrowheads like this (see the predefined
+arrowhead styles in \courier{plain_arrows.asy\} for further examples):
+
+\verbatim
+arrowhead DotHead;
+DotHead.head=new path(path g, position position=EndPoint, pen p=currentpen,
+ real size=0, real angle=arrowangle) {
+ if(size == 0) size=DotHead.size(p);
+ bool relative=position.relative;
+ real position=position.position.x;
+ if(relative) position=reltime(g,position);
+ path r=subpath(g,position,0);
+ pair x=point(r,0);
+ real t=arctime(r,size);
+ pair y=point(r,t);
+ return circle(0.5(x+y),0.5size);
+};
+
+size(100);
+draw((0,0)..(1,1)..(2,0),Arrow(DotHead));
+dot((2,0),red);
+\endverbatim
+
+If you submit your alternate arrowheads to the Forum or the Patch
+Tracking System, we'll consider including them in a future release.

+\section Questions about 2D graphs
+
+\question 02sep:axisticks How can I draw x axis ticks on the right side, with the tick labels on the left side (relative to the axis path)?
+
+\verbatim
+import graph;
+
+size(250,200,IgnoreAspect);
+
+draw(graph(exp,-1,1),red);
+
+xaxis("$x$",RightTicks(Label(align=left)));
+yaxis("$y$",RightTicks);
+\endverbatim
+
+\question 02sep:axislabel How can I reposition the x axis label to three-quarters along the axis length?
+
+\verbatim
+import graph;
+
+size(250,200,IgnoreAspect);
+
+draw(graph(exp,-1,1),red);
+
+xaxis(Label("$x$",0.75),LeftTicks);
+yaxis("$y$",RightTicks);
+\endverbatim
+
+\question 02sep:axislabeldown How can I move the x axis label down 10bp?
+
+\verbatim
+import graph;
+size(250,200,IgnoreAspect);
+
+draw(graph(exp,-1,1),red);
+
+xaxis(shift(0,-10)*"$x$",LeftTicks);
+yaxis("$y$",RightTicks);
+\endverbatim
+
+\question 02sep:threeaxispens Can I use different pens for the axis, the axis label, and the tick labels?
+
+Yes:
+
+\verbatim
+import graph;
+size(300,200,IgnoreAspect);
+
+xlimits(-50,50);
+ylimits(0,100);
+
+xaxis(Label("$x$",MidPoint,red),Bottom,blue,LeftTicks(green));
+yaxis("$y$",Left,RightTicks);
+\endverbatim
+
+\question 02sep:axislabelfont How can I change the font type of the axes label?
+
+\verbatim
+import graph;
+size(300,200,IgnoreAspect);
+
+xlimits(-50,50);
+ylimits(0,100);
+
+xaxis("x",Bottom,Courier("m","n"),LeftTicks);
+yaxis("$y$",Left,RightTicks);
+\endverbatim
+
+\question 02sep:axisticklabelfont How can I change the font type of the tick labels on an axis?
+
+Tick labels are by default typeset in (TeX) math mode, so to use other
+fonts you need to override the default tick format:
+
+\verbatim
+import graph;
+size(300,200,IgnoreAspect);
+
+xlimits(-50,50);
+ylimits(0,100);
+
+xaxis("$x$",Bottom,LeftTicks("%.4g",Courier("m","n")+fontsize(12)));
+yaxis("$y$",Left,RightTicks);
+\endverbatim
+
+\question 26jun:overlappingticklabels How can I prevent axes tick labels from rendering on top of each other?
+
+Either:
+
+(i) give LeftTicks/RightTicks/Ticks the arguments beginlabel=false
+and/or endlabel=false;
+
+(ii) explicitly remove specific ticks and their labels (drawing them manually;
+see \docref{http://www.github.com/vectorgraphics/asymptote/base/graph.asy\} for the definition of NoZero):
+
+\verbatim
+import graph;
+
+size(10cm);
+
+real f(real x) {return x^2;}
+
+draw(graph(f,-2,2));
+
+xaxis(Ticks(NoZero));
+yaxis(Ticks(NoZero));
+
+label("$0$",(0,0),SW);
+\endverbatim
+
+(iii) explicitly remove specific tick labels and draw them manually
+(see \docref{http://www.github.com/vectorgraphics/asymptote/base/graph.asy\} for the definition of NoZeroFormat):
+
+\verbatim
+import graph;
+
+size(10cm);
+
+real f(real x) {return x^2;}
+
+draw(graph(f,-2,2));
+
+xaxis(Ticks(NoZeroFormat));
+yaxis(Ticks(NoZeroFormat));
+
+label("$0$",(0,0),SW);
+\endverbatim
+
+(iv) use the xasy GUI to move overlapping labels;
+
+(v) change the Label argument of LeftTicks, RightTicks, or Ticks to:
+
+\verbatim
+Label(currentpen+overwrite(Move))
+\endverbatim
+
+Solution (v) will move labels that might otherwise overwrite a previous
+label. Other possible overwrite arguments are Allow (allows overlapping
+labels; the default), Suppress (an overlapping label will not be written at
+all), SuppressQuiet, and MoveQuiet. The last two achieve the same result as
+the non-quiet types, but will not notify you which labels are overlapping. See:
+\docref{https://asymptote.sourceforge.io/doc/Pens.html\}.
+
+In the case of a user-specified tick array, you can change which labels get
+suppressed/moved by changing the order of array entries.
+
+\question 04nov:fixedsizegraphs How do I make the plot region of a graph, ignoring labels and legends, have a fixed size?
+
+Either:
+
+i) Specify an explicit unitsize, which overrides any call to \courier{size\}:
+\verbatim
+unitsize(x=1cm,y=2cm);
+\endverbatim
+
+ii) Explicitly tell Asymptote to map the plot region to a specific size:
+\verbatim
+import graph;
+real[] x={0,1,2,3};
+real[] y=x^2;
+draw(graph(x,y),red);
+xaxis("$x$",BottomTop,LeftTicks);
+yaxis("$y$",LeftRight,RightTicks);
+
+size(5cm,5cm,point(SW),point(NE));
+
+label("$f_\mathrm{T}$",point(N),2N);
+\endverbatim
+
+iii) Specify the points in user coordinates that should correspond to a
+given picture size:
+
+\verbatim
+import graph;
+
+size(250,200,IgnoreAspect);
+
+draw(graph(exp,-1,1),red);
+
+xaxis("$x$",BottomTop,LeftTicks);
+yaxis("$y$",LeftRight,RightTicks);
+
+fixedscaling((-1.5,-0.5),(1.5,3.5));
+\endverbatim
+
+In this example, the user coordinate \courier{(-1.5,-0.5)\} will end up
+being the lower left corner of the figure and \courier{(1.5,3.5)\} will be
+the upper right corner. You can use this option to ensure multiple figures
+have the same scaling and same resulting figure size (just ensure the two
+coordinates given to \courier{fixedscaling()\} leaves room for any labels).
+
+See also
+\docref{https://asymptote.sourceforge.io/doc/Frames-and-pictures.html\}.
+
+\question 26jun:graphlimits How can I plot a function f(x) within [0,1]x[0,2] without explicitly calculating the x values for which f(x) hits the boundary?
+
+Call \courier{limits\} with the \courier{Crop\} option before drawing the graph:
+\verbatim
+import graph;
+
+size(250,200,IgnoreAspect);
+
+draw(graph(exp,-1,1),red);
+
+limits((0,0),(1,2),Crop);
+
+xaxis("$x$",BottomTop,LeftTicks);
+yaxis("$y$",LeftRight,RightTicks);
+\endverbatim
+
+See also \docref{https://asymptote.sourceforge.io/doc/graph.html\}.
+
+\question 26jun:custompalettes Is it possible to define customized palettes?
+
+Yes, you may generate your own pen[] array. For example:
+
+\verbatim
+int NColors=32768;
+pen[] MyPalette=new pen[NColors];
+real step=1/(NColors-1.0);
+// Start at black: rgb(0,0,0)
+// End at yellow: rgb(1,1,0)
+for(int i=0; i < NColors; ++i) {
+ real rgval=i*step;
+ MyPalette[i]=rgb(rgval,rgval,0.0);
+}
+\endverbatim
+
+\question 26jun:factorial Is there an easy way to graph factorial functions nicely?
+
+The example below shows a continuous function and two methods for placing
+markers at integer values of x:
+
+\verbatim
+import graph;
+
+size(200,200,IgnoreAspect);
+
+real factorial(real t) {return gamma(t+1);}
+
+scale(Linear,Log);
+
+// Graph the factorial function.
+draw(graph(factorial,0,10));
+
+// Method 1: Draw nodes, but hide line
+pair F(int t) {return (t,factorial(t));}
+// Graph of factorial function from 0 to 10
+pair[] z=sequence(F,11);
+draw(graph(z),invisible,marker(scale(0.8mm)*unitcircle,blue,Fill));
+
+// Method 2: Nongraphing routines require explicit scaling:
+pair dotloc(int t) {return Scale(F(t));}
+pair[] dotlocs=sequence(dotloc,11);
+dot(dotlocs);
+
+xaxis("$x$",BottomTop,LeftTicks);
+yaxis("$y$",LeftRight,RightTicks);
+\endverbatim
+
+\question 26jun:length How do I indicate that a certain length should be exactly the size I prescribe with no rescaling, within a picture which has its own size?
+
+Here's an easy way to do this.
+
+\verbatim
+size(12cm,0);
+
+void distance(picture pic=currentpicture, pair A, pair B, Label L="", real n=0,
+ pen p=currentpen)
+{
+ real d=3mm;
+ path g=A--B;
+ transform T=shift(-n*d*unit(B-A)*I);
+ pic.add(new void(frame f, transform t) {
+ picture opic;
+ path G=T*t*g;
+ draw(opic,Label(L,Center,UnFill(1)),G,p,Arrows(NoFill),Bars,PenMargins);
+ add(f,opic.fit());
+ });
+ pic.addBox(min(g),max(g),T*min(p),T*max(p));
+}
+
+pair A=(0,0), B=(3,3);
+
+dot(A);
+dot(B);
+
+distance(A,B,"$\ell$",1);
+\endverbatim
+
+\question 26jun:log2 How can I make the y axis display base-2 logarithmic values?
+
+See the example \docref{https://asymptote.sourceforge.io/gallery/2D graphs/log2graph.asy\}.
+
+\question 27jun:align How can I align the x axes of two graphs on the same figure?
+
+An easy way to do this, if the axes to be aligned have the same scaling
+and size, is illustrated in the example \docref{https://asymptote.sourceforge.io/gallery/2D graphs/alignedaxis.asy\}.
+
+Here is a more general solution to the problem of aligning two arbitrary axes.
+One fits the second picture to a frame based on the horizontal scaling for
+the first picture:
+
+\verbatim
+import graph;
+
+real width=15cm;
+real aspect=0.3;
+
+picture pic1,pic2;
+
+size(pic1,width,aspect*width,IgnoreAspect);
+size(pic2,width,aspect*width,IgnoreAspect);
+
+scale(pic1,false);
+scale(pic2,false);
+
+real xmin1=6;
+real xmax1=9;
+real xmin2=8;
+real xmax2=16;
+
+real a1=1;
+real a2=0.001;
+
+real f1(real x) {return a1*sin(x/2*pi);}
+real f2(real x) {return a2*sin(x/4*pi);}
+
+draw(pic1,graph(pic1,f1,xmin1,xmax1));
+draw(pic2,graph(pic2,f2,xmin2,xmax2));
+
+xaxis(pic1,Bottom,LeftTicks());
+yaxis(pic1,"$f_1(x)$",Left,RightTicks);
+
+xaxis(pic2,"$x$",Bottom,LeftTicks(Step=4));
+yaxis(pic2,"$f_2(x)$",Left,RightTicks);
+
+yequals(pic1,0,Dotted);
+yequals(pic2,0,Dotted);
+
+pair min1=point(pic1,SW);
+pair max1=point(pic1,NE);
+
+pair min2=point(pic2,SW);
+pair max2=point(pic2,NE);
+
+real scale=(max1.x-min1.x)/(max2.x-min2.x);
+real shift=min1.x/scale-min2.x;
+
+transform t1=pic1.calculateTransform();
+transform t2=pic2.calculateTransform();
+transform T=xscale(scale*t1.xx)*yscale(t2.yy);
+
+add(pic1.fit());
+real height=truepoint(N,user=false).y-truepoint(S,user=false).y;
+add(shift(0,-height)*(shift(shift)*pic2).fit(T));
+\endverbatim
+
+\question 27jun:changeaxis How can I change the direction of the y-axis, such that negatives values are on the upper y-axis?
+
+Here is a simple example (see also the example \docref{https://asymptote.sourceforge.io/gallery/2D graphs/diatom.asy\} or the discussion
+of Linear(-1) in the documentation):
+
+\verbatim
+import graph;
+size(250,200,IgnoreAspect);
+
+scale(Linear,Linear(-1));
+
+draw(graph(log,0.1,10),red);
+
+xaxis("$x$",LeftTicks);
+yaxis("$y$",RightTicks);
+\endverbatim
+
+\question 27jun:functioncolor How can I fill a path with a function that defines the color of each location?
+
+Use \courier{functionshade\} with a PDF tex engine, as illustrated
+by the example {functionshading.asy}.
+
+If you want to produce PostScript output, an approximate solution for now
+would be to superimpose a fine grid and specify colors to
+\courier{latticeshade\} that depend on position as a single pen[][]
+lattice. Alternatively, it may be more efficient to use \courier{tensorshade}.
+
+\question 27jun:nonexplicitfun Is there a way to draw a function that is not explicitly given, such as (y - 2)^2 = x - 1 ?
+
+Yes, use the parametric form
+
+\verbatim
+y=t
+x=(t-2)^2+1
+\endverbatim
+
+See the example \docref{https://asymptote.sourceforge.io/gallery/2D graphs/parametricgraph.asy\}.
+
+\question 27jun:scalesecondaryaxis Is it possible to reverse or stretch an axis?
+
+The real scaling argument to Linear is used to stretch (or reverse) the axis.
+To see the effect of axis stretching, be sure not to specify IgnoreAspect in
+the picture size command.
+
+A secondary axis has the same length as the primary axis, so stretching cannot
+have any effect. But one can still reverse the axis, with Linear(-1).
+
+\question 02sep:emptymarkers Why can't I use the UnFill option to draw graphs with empty markers?
+
+UnFill won't work here because it only affects the local frame the markers
+are initially drawn on, before being added to currentpicture.
+Here is a way of achieving the desired effect (assuming a white background):
+
+\verbatim
+import graph;
+size(10cm,0);
+pair[] z={(0,0),(0.5,0.5),(1,1)};
+path g=graph(z);
+
+draw(shift(0,.5)*g,marker(scale(5)*unitcircle,FillDraw(white)));
+
+xaxis(BottomTop,LeftTicks);
+yaxis(LeftRight,RightTicks);
+\endverbatim
+
+\question 02sep:paletterange How can I force several images to use the same palette range (e.g. the entire 0-255 grayscale range)?
+
+The palette color space corresponds to a range of values specified by the
+argument range, which can be \courier{Full\}, \courier{Automatic\} or an
+explicit range \courier{Range(pair min, pair max)\}. Here \courier{Full}
+specifies a range varying from the minimum to maximum values of the
+function over the sampling interval, while \courier{Automatic\} selects
+"nice" limits.

+\section Questions about programming
+
+\question 27jun:comporint Is Asymptote an interpreter or a compiler?
+
+Asymptote compiles Asymptote commands into its own virtual machine code. It
+then runs this pseudocode on a virtual machine to produce PostScript code.
+
+\question 05sep:framepicture What is the difference between a frame and a picture?
+
+Frames are canvases for drawing in PostScript coordinates. While working
+with frames directly is occasionally necessary for constructing deferred
+drawing routines, pictures are usually more convenient to work with.
+See \qref unitsizes.
+
+\question 05sep:pathguide What is the difference between a path and a guide?
+
+A path is a cubic spline with fixed endpoint conditions.
+
+A guide is an unresolved cubic spline (list of cubic-spline nodes and
+control points). A guide is like a path except that the computation of the cubic
+spline is deferred until drawing time (when it is resolved into a path);
+this allows two guides with free endpoint conditions to be joined together
+smoothly.
+
+\question 27jun:picarray What is a convenient way to declare and initialize an array of pictures?
+
+You could write yourself a routine such as:
+\verbatim
+picture[] picture(int n) {
+ picture[] pic;
+ for(int i=0; i < n; ++i) {
+ pic[i]=new picture;
+ size(pic[i],19cm,0);
+ }
+ return pic;
+}
+
+picture[] pic=picture(6);
+\endverbatim
+
+\question 27jun:genarrays Is there a way to define functions that act on arrays in general (i.e. work for arrays of any type)?
+
+Generic types aren't yet implemented.
+
+But for now you can at least say
+\verbatim
+typedef string T;
+include F;
+
+typedef real T;
+include F;
+\endverbatim
+
+where \courier{F.asy\} contains some type-dependent code like
+\verbatim
+T[] operator $(T A, T B) {return new T[] {A,B};}
+\endverbatim
+
+\question 27jun:cirdep Is there any way to declare structures ahead of their definition, e.g. where struct A performs some operation on struct B, but B contains an A member?
+
+Asymptote does not support forward declaration of types. You can, however,
+nest structures, so that both types are visible for parts of the bodies of
+both structure definitions. For example:
+
+\verbatim
+struct B {
+ typedef void someroutine(B b);
+
+ static struct A {
+ someroutine routine;
+ void operator init(someroutine routine) {
+ this.routine=routine;
+ }
+ }
+
+ string test="Testing";
+}
+
+typedef B.A A;
+
+A a=B.A(new void(B b){write(b.test);});
+
+B b;
+a.routine(b);
+\endverbatim
+
+\question 04nov:static Where are static variables in for loops allocated?
+
+In the example
+
+\verbatim
+void f() {
+ for(int i=0; i < 3; ++i) {
+ static int n;
+ ++n;
+ write(n);
+ }
+}
+
+f(); // Writes 1, 2, 3
+\endverbatim
+
+the static qualifier means that \courier{n\} is allocated not just outside
+of the for loop, but also outside the function. This is clear if you call
+\courier{f\} multiple times; there is still only one instance of \courier{n\}.
+
+The "level" of a variable (where it is allocated) has nothing to do with
+the "scope" of a variable (how long it can be referred to by name).
+The curly braces enclosing a block affect only a variable's scope, not
+its level.
+
+Static modifiers are meaningless at the top level; they generate a warning
+and are simply ignored:
+
+\verbatim
+for(int i=0; i < 3; ++i) {
+ static int n;
+ ++n;
+ write(n);
+}
+// Writes warning about top-level static modifier and then 1, 1, 1
+\endverbatim
+
+Since version 1.22, non-static variables allocated in a loop body are allocated
+anew every iteration. This is only noticable in obscure cases where a variable
+in a loop is accessed in the closure of a function defined in the loop:
+
+\verbatim
+int f();
+
+for(int i=0; i < 10; ++i) {
+ int j=10*i;
+ if(i == 5)
+ f=new int() {return j;};
+}
+
+write(f()); // Writes 50
+\endverbatim
+
+Variables in the body of a loop last as long as that iteration of the loop,
+unless they are kept alive by a function closure as in the example above. In a
+function body, variables will last at least as long as the function call, though
+because of closures and garbage collection, they may last longer than that. If
+defined at the top level of a file or at the interactive prompt, they will last
+at least until the end of the file or prompt's run.
+
+\question 26jun:debug Is there a debugger for asy?
+
+Yes, Asymptote includes a line-based debugger:
+
+\docref{https://asymptote.sourceforge.io/doc/Debugger.html\}
+
+\question 27jun:patches Do you accept patches for Asymptote?
+
+Yes, in fact we would prefer that users submit patches for customized features
+(to \docref{http://sourceforge.net/tracker/?atid=685685&group_id=120000\})
+instead of relying on us to do all of the coding. Development will proceed
+faster that way.

+\section Questions about differences between Asymptote and MetaPost
+
+\question 29jun:interp What is the equivalent of the MetaPost c[a,b] interpolation operator?
+
+\verbatim
+interp(a,b,c);
+\endverbatim
+
+\question 02sep:automaticscaling How does picture scaling differ in Asymptote and MetaPost?
+
+Asymptote includes an optional facility to do automatic scaling of pictures
+to achieve a given overall picture size, whereas Metapost only supports manual
+scaling. Asymptote defers drawing of objects drawn to pictures and
+distinguishes between true-size objects and objects that should scale with
+the picture size. The resulting linear programming problem is solved via
+the Simplex method.
+
+See the \docref{https://asymptote.sourceforge.io/gallery/dimension.asy\} example for an example of how deferred drawing is
+used to accomodate both user and true-size (PostScript) coordinates.
+
+\question 02sep:manualscaling How can I avoid automatic scaling of a picture?
+
+If you really like Metapost-style manual (hard-wired) scaling either:
+
+(i) use the default size(0,0) for the entire picture and do all of the
+scaling by hand, just like in MetaPost;
+
+(ii) draw to a separate picture pic and add(pic.fit());
+
+(iii) use frames.
+
+\question 23jun:mp3dots What is the equivalent of MetaPost ... command?
+
+The connector \courier{::\} is a macro for tension atleast 1:
+
+\verbatim
+size(100);
+pair z0=(0,0);
+pair z1=(1,0.25);
+pair z2=(2,0);
+draw(z0{up}::z1{right}::z2{down});
+\endverbatim
+
+\question 23jun:mppickup What is the equivalent of the MetaPost pickup command?
+
+Just say, for example:
+
+\verbatim
+currentpen=red;
+\endverbatim
+
+\question 29aug:whatever What is the equivalent of the MetaPost whatever command?
+
+Asymptote does not implicitly solve linear equations and therefore does not
+have the notion of a \courier{whatever\} unknown. Such a facility could
+certainly be added (perhaps using the notation \courier{?=\} since
+\courier{=\} means assignment).
+However, the most common uses of \courier{whatever\} in MetaPost are covered by
+functions like \courier{extension\} in \courier{math.asy\}:
+\verbatim
+pair extension(pair P, pair Q, pair p, pair q);
+\endverbatim
+this returns the intersection point of the extensions of the line segments
+\courier{PQ\} and \courier{pq\}. We find using routines like
+\courier{extension\} more explicit and less confusing to new users. But we
+could be persuaded to add something similar if someone can justify the
+need. In the meantime, one can always use the explicit built-in linear
+solver \courier{solve\} (see
+\docref{https://asymptote.sourceforge.io/doc/solve.html\}), which uses LU
+decomposition.
+
+\question 23jun:lray What is the equivalent for the MetaPost command for \courier{lray - horiz*v - verti*u = whatever*(LightSource - R)\}, a system of three linear equations for three unknowns: \courier{horiz, verti, whatever\}?
+
+Since \courier{horiz*v+verti*u\} spans a plane, you could use
+\verbatim
+real intersect(vector P, vector Q, vector n, vector Z);
+\endverbatim
+
+to find the intersection time for the line
+\courier{lray-whatever*(LightSource - R)\}
+and then extract the three desired values from there. (You'll still need to
+use the built-in explicit linear solver to solve a 2x2 system to get
+\courier{horiz\} and \courier{verti\}.)
+
+\question 27jun:unitsizes In MetaPost, it is possible to have a drawing remain the same size in different pictures by defining a unit \courier{u\} and explicitly multiply all the coordinates by \courier{u\}. Is there a better way to do this in Asymptote?
+
+Yes, Asymptote has a better way: you definitely don't want to manually scale
+all of your coordinates. To make the user coordinates represent multiples
+of exactly \courier{1cm\}:
+
+\verbatim
+unitsize(1cm);
+draw(unitsquare);
+\endverbatim
+
+One can also specify different x and y unit sizes:
+
+\verbatim
+unitsize(x=1cm,y=2cm);
+draw(unitsquare);
+\endverbatim
+
+Another way is to draw your fixed size object to a frame and add it to
+currentpicture like this:
+
+\verbatim
+path p=(0,0)--(1,0);
+frame object;
+draw(object,scale(100)*p);
+
+add(object);
+add(object,(0,-10));
+\endverbatim
+
+To understand the difference between frames and pictures, try this:
+
+\verbatim
+size(300,300);
+
+path p=(0,0)--(1,0);
+picture object;
+draw(object,scale(100)*p);
+
+add(object);
+add(object,(0,-10)); // Adds truesize object to currentpicture
+\endverbatim
+
+\question 28jun:tiles In MetaPost, one could produce tiling pictures by generating a picture, and then clipping the picture to a rectangle of fixed dimensions around the center of the picture. How is that done in Asymptote?
+
+If you are using currentpicture the way one would in MetaPost (drawing in
+raw PostScript coordinates), you can simply do something like:
+
+\verbatim
+fill((0,0)--(100,100)--(200,0)--cycle);
+
+pair center(picture pic=currentpicture) {return 0.5*(pic.min()+pic.max());}
+
+real height=100;
+real width=100;
+pair delta=0.5(width,height);
+pair c=center();
+clip(box(c-delta,c+delta));
+\endverbatim
+
+However, drawing in PostScript coordinates is often inconvenient. Here's the
+Asymptote way of doing the same thing, using deferred drawing:
+
+\verbatim
+size(200,100);
+fill((0,0)--(1,1)--(2,0)--cycle);
+
+void clip(picture pic=currentpicture, real width, real height)
+{
+ pic.clip(new void (frame f, transform) {
+ pair center=0.5(min(f)+max(f));
+ pair delta=0.5(width,height);
+ clip(f,box(center-delta,center+delta));
+ });
+}
+
+clip(100,100);
+\endverbatim
+
+See also the discussion of tilings in the documentation:
+\docref{https://asymptote.sourceforge.io/doc/Pens.html\}.

+\section Questions about output
+
+\question 27jun:psviewer How can I disable automatic invocation of the PS viewer after an asy file is done processing?
+
+It's actually not on by default, unless you happen to be using Microsoft
+Windows (because that is what most Microsoft Windows users
+expect). Microsoft Windows users can turn this feature off with the
+command-line option -noV or by putting
+
+\verbatim
+import settings;
+interactiveView=false;
+batchView=false;
+\endverbatim
+
+in their \courier{config.asy\} file. See
+\docref{https://asymptote.sourceforge.io/doc/Options.html\}.
+
+\question 26jun:jpeg How do I output jpeg images?
+
+If you have the ImageMagick convert program installed, simply type
+
+\verbatim
+asy -f jpg test.asy
+\endverbatim
+
+\question 27jun:embedbitmaps Can I embed bitmaps (photos) into my drawings and position and scale them?
+
+Convert them to eps format and use the graphic(string) function just like a
+Label:
+
+\verbatim
+label(graphic("file"),(0,0));
+\endverbatim
+
+See the example \docref{https://asymptote.sourceforge.io/gallery/orthocenter.asy\} and
+\docref{https://asymptote.sourceforge.io/doc/label.html\}.
+
+\question 28jun:directpdf Does Asymptote support direct PDF output?
+
+Yes, PDF output can be produced by the -f pdf option or -tex pdflatex option.
+This supports transparency, annotations, embedded movies, and U3D/PRC content.
+
+\question 28jun:bigpictures How to I produce large pictures of high quality in raster format (e.g. png, giff etc).
+
+Try using some of the options to convert, mainly -geometry and -density. For example:
+\verbatim
+convert -geometry 1000x3000 example.eps example.png
+\endverbatim
+
+You can also change the default resolution of the image with:
+\verbatim
+convert -geometry 1000x3000 -density 300 -units PixelsPerInch example.eps example.png
+\endverbatim
+This does not change the number of pixels in the image, but just gives a hint
+as to how large each pixel should be displayed.
+
+If you include the -density option without the -geometry option, convert will
+keep the image size constant (so a 4cm x 3cm eps figure will generate a 4cm x
+3cm png
+image).
+
+\question 28jun:multipage Is it possible to produce multi-page documents with asymptote?
+
+Yes, simply call the newpage() function. This is used by the
+\courier{slide.asy\} package to produce high-quality slide presentations
+(easier to use than Prosper).
+

+
+Question 1.1. What is Asymptote?
+
+Asymptote is a vector graphics language designed for technical graphics,
+inspired by MetaPost but with IEEE floating-point numerics, native
+three-dimensional graphics, Grayscale/RGB/CMYK colourspaces, and a
+C++-like syntax. Unlike MetaPost, it natively supports multiple-segment
+paths (and hence regions other than simply connected ones), tiling
+patterns, Gouraud shading, tensor patch shading, and PostScript images.
+
+
+File: asy-faq.info, Node: Question 1.2, Next: Question 1.3, Previous: Question 1.1, Up: Section 1
+
+Question 1.2. How do I obtain Asymptote?
+
+Binary releases are available for Linux, MacOS X, and Microsoft Windows
+platforms, in addition to full source code, from the website
+https://asymptote.sourceforge.io/. Many Linux distributions (such as
+RedHat and Debian) now include an Asymptote package (check your
+distribution's documentation for further information about this).

+Question 1.3. Where can I ask questions about Asymptote?
+
+If you have a question, please try to find an answer in this FAQ, in the
+extensive Asymptote documentation at

+Question 1.5. In the internal Asymptote source code, what does the name camp refer to?
+
+That was our original tentative name for this project, which stood for
+"C's Answer to MetaPost" (the language that inspired Asymptote). However,
+we eventually decided that the name Asymptote better emphasizes the
+mathematical and graphical nature of this language.

+Question 2.1. Is it possible to install Asymptote on Mac OS X?
+
+It is easy to compile Asymptote directly from the source code at
+http://sourceforge.net/project/showfiles.php?group_id=120000 We recommend
+first upgrading to the latest GNU readline library, unless you don't care
+about interactive readline support (in which case configure will
+automatically detect and disable obsolete versions of the readline
+library). Marius Schamschula also maintains a binary package for various
+MacOS X platforms

+
+This means either that you have a binary distribution for another MAC
+architecture, or (according to Marius Schamschula) that you may have a
+missing library. The simplest solution is to compile Asymptote directly
+from the official source:

+Question 2.7. Do I need the tkinter package to install an Asymptote rpm binary?
+
+No, you don't need tkinter unless you want to try out the GUI xasy. Try

+Question 2.8. What does the path %USERPROFILE%\.asy\config.asy mean?

+
+Question 2.9. Why do I get the error "string not terminated" when I try to set settings.dir="C:\asymptote\";?
+
+The backslash is an escape character here, so \" is interpreted as a
+verbatim quotation mark, leaving the string without a terminating
+quotation mark. Fortunately, this is the only escaped character in
+double-quoted strings. A final backslash isn't needed here anyway, but
+should you really want one somewhere, you can say:
+settings.dir="C:\asymptote"+'\\';.

+
+While it is easier to set the corresponding Asymptote configuration

+Microsoft Windows environment variables:
+
+Click on the [Start] button

+
+Question 2.11. Under Microsoft Windows XP, why do I get an error like "Invalid Parameter - 432x432"?
+
+This means that ImageMagick wasn't properly installed and you are using
+the MSDOS convert program rather than the ImageMagick one. Or you may have
+installed ImageMagick but ran Asymptote from an existing MSDOS window. In
+that case, simply open a new window and try again. If that doesn't work,
+check that
+
+convert --version
+returns something like

+Question 2.12. Why does Asymptote freeze upon trying to draw a label with my MikTex installation under Microsoft Windows?
+
+Likely, this means that latex and dvips are not in your default path. Try
+adding the appropriate paths in your config.asy file, for example:
+
+import settings;
+latex="C:\Program Files\MiKTeX 2.7\miktex\bin\latex.exe";

+
+Question 3.1. Why do I get a syntax error message when I specify an integer value for the path tension?
+
+What is happening here is that
+
+draw((0,0)..tension 2..(0,50)..(100,100));
+is read as
+
+draw((0,0)..tension 2. .(0,50)..(100,100));
+So the first . after the two is treated as a decimal point. Just put a
+space after the integer tension value:
+
+draw((0,0)..tension 2 ..(0,50)..(100,100));
+
+File: asy-faq.info, Node: Question 3.2, Next: Question 4.1, Previous: Question 3.1, Up: Section 3
+
+Question 3.2. Shouldn't dots always be the same size?
+
+From the documentation:
+
+"The dot command defined in the module plain draws a dot having a diameter
+equal to an explicit pen linewidth or the default linewidth magnified by
+dotfactor (6 by default)."
+
+Thus, when you use the default pen, the dot will have size 6*linewidth,
+but when you give a pen with an explicit width specified, you will have a
+dot of size linewidth. If you want the first case to behave like the
+second, you may set dotfactor=1.

+
+Question 4.10. The binary operator * can be used to scale the color of a pen by a real number. Does this scaling factor have to be less than 1?
+
+The scaling factor can be greater than 1. But keep in mind that the rgb
+color components saturate at 1.
+
+Try
+write(cyan); write(0.8*cyan); write(1.5*cyan);
+and you will quickly see what is going on.
+
+To get a lighter cyan you can say white+cyan, which yields rgb(0.5,1,1).
+If you want something even lighter specify the rgb colors directly, for
+example, rgb(0.9,1,1).
+
+Alternatively, work in cmyk colour space, which is nicer in that it
+handles saturation separately from hue:
+
+0.1*Cyan is light and 0.9*Cyan is dark. You can also say 0.1*cmyk(red).

+
+Question 5.1. How do I draw two arrows at arbitrary positions along a path?
+
+Assuming that at least one of the arrowheads is to be filled, you can do
+this:
+
+size(200);
+path g = (0,0)..(1,3)..(3,0);
+draw(g,Arrow(Relative(0.9)));
+add(arrow(g,invisible,FillDraw(black),Relative(0.5)));
+add(arrow(reverse(g),invisible,FillDraw(white,black),Relative(0.9)));
+If both of the arrowheads are to be drawn with filltype NoFill, one will
+need to create a specialized version of the arrow routine in
+plain_arrows.asy:
+
+void arrow(frame f, arrowhead arrowhead=DefaultHead,

+File: asy-faq.info, Node: Question 5.3, Next: Question 5.4, Previous: Question 5.2, Up: Section 5
+
+Question 5.3. How do I change the size of all arrows?
+
+To override the arrowsize you can give every Arrow drawing attribute a
+real size argument. If you want to do this globally, you can override the
+pen-dependent arrowsize function like this:
+
+DefaultHead.size=new real(pen p=currentpen) {return 2mm;};
+

+
+Question 5.4. Can I create other arrowhead styles?
+
+Yes, you can build custom arrowheads like this (see the predefined
+arrowhead styles in plain_arrows.asy for further examples):
+
+arrowhead DotHead;
+DotHead.head=new path(path g, position position=EndPoint, pen p=currentpen,
+ real size=0, real angle=arrowangle) {
+ if(size == 0) size=DotHead.size(p);
+ bool relative=position.relative;
+ real position=position.position.x;
+ if(relative) position=reltime(g,position);
+ path r=subpath(g,position,0);
+ pair x=point(r,0);
+ real t=arctime(r,size);
+ pair y=point(r,t);
+ return circle(0.5(x+y),0.5size);
+};
+
+size(100);
+draw((0,0)..(1,1)..(2,0),Arrow(DotHead));
+dot((2,0),red);
+If you submit your alternate arrowheads to the Forum or the Patch
+Tracking System, we'll consider including them in a future release.

+Tick labels are by default typeset in (TeX) math mode, so to use other

+
+import graph;
+size(300,200,IgnoreAspect);
+

+
+Question 6.7. How can I prevent axes tick labels from rendering on top of each other?
+
+Either:
+
+(i) give LeftTicks/RightTicks/Ticks the arguments beginlabel=false and/or
+endlabel=false;
+
+(ii) explicitly remove specific ticks and their labels (drawing them
+manually; see
+http://www.github.com/vectorgraphics/asymptote/base/graph.asy for the
+definition of NoZero):
+
+import graph;
+
+size(10cm);
+
+real f(real x) {return x^2;}
+
+draw(graph(f,-2,2));
+
+xaxis(Ticks(NoZero));
+yaxis(Ticks(NoZero));
+
+label("$0$",(0,0),SW);
+(iii) explicitly remove specific tick labels and draw them manually (see
+http://www.github.com/vectorgraphics/asymptote/base/graph.asy for the
+definition of NoZeroFormat):
+
+import graph;
+
+size(10cm);
+
+real f(real x) {return x^2;}
+
+draw(graph(f,-2,2));
+
+xaxis(Ticks(NoZeroFormat));
+yaxis(Ticks(NoZeroFormat));
+
+label("$0$",(0,0),SW);
+(iv) use the xasy GUI to move overlapping labels;
+
+(v) change the Label argument of LeftTicks, RightTicks, or Ticks to:
+
+Label(currentpen+overwrite(Move))
+Solution (v) will move labels that might otherwise overwrite a previous
+label. Other possible overwrite arguments are Allow (allows overlapping
+labels; the default), Suppress (an overlapping label will not be written
+at all), SuppressQuiet, and MoveQuiet. The last two achieve the same
+result as the non-quiet types, but will not notify you which labels are
+overlapping. See: https://asymptote.sourceforge.io/doc/Pens.html.
+
+In the case of a user-specified tick array, you can change which labels
+get suppressed/moved by changing the order of array entries.

+
+Question 6.8. How do I make the plot region of a graph, ignoring labels and legends, have a fixed size?
+
+Either:
+
+i) Specify an explicit unitsize, which overrides any call to size:
+unitsize(x=1cm,y=2cm);
+ii) Explicitly tell Asymptote to map the plot region to a specific size:
+import graph;
+real[] x={0,1,2,3};
+real[] y=x^2;
+draw(graph(x,y),red);
+xaxis("$x$",BottomTop,LeftTicks);
+yaxis("$y$",LeftRight,RightTicks);
+
+size(5cm,5cm,point(SW),point(NE));
+
+label("$f_\mathrm{T}$",point(N),2N);
+iii) Specify the points in user coordinates that should correspond to a
+given picture size:
+
+import graph;
+
+size(250,200,IgnoreAspect);
+
+draw(graph(exp,-1,1),red);
+
+xaxis("$x$",BottomTop,LeftTicks);
+yaxis("$y$",LeftRight,RightTicks);
+
+fixedscaling((-1.5,-0.5),(1.5,3.5));
+In this example, the user coordinate (-1.5,-0.5) will end up being the
+lower left corner of the figure and (1.5,3.5) will be the upper right
+corner. You can use this option to ensure multiple figures have the same
+scaling and same resulting figure size (just ensure the two coordinates
+given to fixedscaling() leaves room for any labels).

+
+The real scaling argument to Linear is used to stretch (or reverse) the
+axis. To see the effect of axis stretching, be sure not to specify

+way of achieving the desired effect (assuming a white background):

+Range(pair min, pair max). Here Full} specifies a range varying from the

+
+Question 7.1. Is Asymptote an interpreter or a compiler?
+
+Asymptote compiles Asymptote commands into its own virtual machine code.

+
+Question 7.2. What is the difference between a frame and a picture?
+
+Frames are canvases for drawing in PostScript coordinates. While working
+with frames directly is occasionally necessary for constructing deferred
+drawing routines, pictures are usually more convenient to work with. See
+*Note Question 8.8:: `In MetaPost, it is possible to have a drawing remain

+
+Question 7.3. What is the difference between a path and a guide?
+
+A path is a cubic spline with fixed endpoint conditions.
+
+A guide is an unresolved cubic spline (list of cubic-spline nodes and
+control points). A guide is like a path except that the computation of the
+cubic spline is deferred until drawing time (when it is resolved into a
+path); this allows two guides with free endpoint conditions to be joined
+together smoothly.

+typedef string T;

+
+Question 7.6. Is there any way to declare structures ahead of their definition, e.g. where struct A performs some operation on struct B, but B contains an A member?
+
+Asymptote does not support forward declaration of types. You can, however,
+nest structures, so that both types are visible for parts of the bodies of
+both structure definitions. For example:
+
+struct B {
+ typedef void someroutine(B b);
+
+ static struct A {
+ someroutine routine;
+ void operator init(someroutine routine) {
+ this.routine=routine;
+ }
+ }
+
+ string test="Testing";
+}
+
+typedef B.A A;
+
+A a=B.A(new void(B b){write(b.test);});
+
+B b;
+a.routine(b);

+
+Question 7.7. Where are static variables in for loops allocated?
+
+In the example
+
+void f() {
+ for(int i=0; i < 3; ++i) {
+ static int n;
+ ++n;
+ write(n);
+ }
+}
+
+f(); // Writes 1, 2, 3
+the static qualifier means that n is allocated not just outside of the for
+loop, but also outside the function. This is clear if you call f multiple
+times; there is still only one instance of n.
+
+The "level" of a variable (where it is allocated) has nothing to do with
+the "scope" of a variable (how long it can be referred to by name). The
+curly braces enclosing a block affect only a variable's scope, not its
+level.
+
+Static modifiers are meaningless at the top level; they generate a warning
+and are simply ignored:
+
+for(int i=0; i < 3; ++i) {
+ static int n;
+ ++n;
+ write(n);
+}
+// Writes warning about top-level static modifier and then 1, 1, 1
+Since version 1.22, non-static variables allocated in a loop body are
+allocated anew every iteration. This is only noticable in obscure cases
+where a variable in a loop is accessed in the closure of a function
+defined in the loop:
+
+int f();
+
+for(int i=0; i < 10; ++i) {
+ int j=10*i;
+ if(i == 5)
+ f=new int() {return j;};
+}
+
+write(f()); // Writes 50
+Variables in the body of a loop last as long as that iteration of the
+loop, unless they are kept alive by a function closure as in the example
+above. In a function body, variables will last at least as long as the
+function call, though because of closures and garbage collection, they may
+last longer than that. If defined at the top level of a file or at the
+interactive prompt, they will last at least until the end of the file or
+prompt's run.

+
+Question 8.2. How does picture scaling differ in Asymptote and MetaPost?
+
+Asymptote includes an optional facility to do automatic scaling of
+pictures to achieve a given overall picture size, whereas Metapost only
+supports manual scaling. Asymptote defers drawing of objects drawn to
+pictures and distinguishes between true-size objects and objects that
+should scale with the picture size. The resulting linear programming
+problem is solved via the Simplex method.
+
+See the https://asymptote.sourceforge.io/gallery/dimension.asy example for
+an example of how deferred drawing is used to accomodate both user and
+true-size (PostScript) coordinates.

+
+Question 8.3. How can I avoid automatic scaling of a picture?
+
+If you really like Metapost-style manual (hard-wired) scaling either:
+
+(i) use the default size(0,0) for the entire picture and do all of the
+scaling by hand, just like in MetaPost;
+
+(ii) draw to a separate picture pic and add(pic.fit());
+
+(iii) use frames.

+
+Question 8.6. What is the equivalent of the MetaPost whatever command?
+
+Asymptote does not implicitly solve linear equations and therefore does
+not have the notion of a whatever unknown. Such a facility could certainly
+be added (perhaps using the notation ?= since = means assignment).
+However, the most common uses of whatever in MetaPost are covered by
+functions like extension in math.asy:
+pair extension(pair P, pair Q, pair p, pair q);
+this returns the intersection point of the extensions of the line segments
+PQ and pq. We find using routines like extension more explicit and less
+confusing to new users. But we could be persuaded to add something similar
+if someone can justify the need. In the meantime, one can always use the
+explicit built-in linear solver solve (see
+https://asymptote.sourceforge.io/doc/solve.html), which uses LU
+decomposition.

+
+Question 8.7. What is the equivalent for the MetaPost command for lray - horiz*v - verti*u = whatever*(LightSource - R), a system of three linear equations for three unknowns: horiz, verti, whatever?
+
+Since horiz*v+verti*u spans a plane, you could use
+real intersect(vector P, vector Q, vector n, vector Z);
+to find the intersection time for the line lray-whatever*(LightSource -
+R) and then extract the three desired values from there. (You'll still
+need to use the built-in explicit linear solver to solve a 2x2 system to
+get horiz and verti.)

+
+Question 8.8. In MetaPost, it is possible to have a drawing remain the same size in different pictures by defining a unit u and explicitly multiply all the coordinates by u. Is there a better way to do this in Asymptote?
+
+Yes, Asymptote has a better way: you definitely don't want to manually
+scale all of your coordinates. To make the user coordinates represent
+multiples of exactly 1cm:
+
+unitsize(1cm);
+draw(unitsquare);
+One can also specify different x and y unit sizes:
+
+unitsize(x=1cm,y=2cm);
+draw(unitsquare);
+Another way is to draw your fixed size object to a frame and add it to
+currentpicture like this:
+
+path p=(0,0)--(1,0);
+frame object;
+draw(object,scale(100)*p);
+
+add(object);
+add(object,(0,-10));
+To understand the difference between frames and pictures, try this:
+
+size(300,300);
+
+path p=(0,0)--(1,0);
+picture object;
+draw(object,scale(100)*p);
+
+add(object);
+add(object,(0,-10)); // Adds truesize object to currentpicture
+

+
+Question 8.9. In MetaPost, one could produce tiling pictures by generating a picture, and then clipping the picture to a rectangle of fixed dimensions around the center of the picture. How is that done in Asymptote?
+
+If you are using currentpicture the way one would in MetaPost (drawing in
+raw PostScript coordinates), you can simply do something like:
+
+fill((0,0)--(100,100)--(200,0)--cycle);
+
+pair center(picture pic=currentpicture) {return 0.5*(pic.min()+pic.max());}
+
+real height=100;
+real width=100;
+pair delta=0.5(width,height);
+pair c=center();
+clip(box(c-delta,c+delta));
+However, drawing in PostScript coordinates is often inconvenient. Here's
+the Asymptote way of doing the same thing, using deferred drawing:
+
+size(200,100);
+fill((0,0)--(1,1)--(2,0)--cycle);
+
+void clip(picture pic=currentpicture, real width, real height)
+{
+ pic.clip(new void (frame f, transform) {
+ pair center=0.5(min(f)+max(f));
+ pair delta=0.5(width,height);
+ clip(f,box(center-delta,center+delta));
+ });
+}
+
+clip(100,100);

+
+Question 9.1. How can I disable automatic invocation of the PS viewer after an asy file is done processing?
+
+It's actually not on by default, unless you happen to be using Microsoft
+Windows (because that is what most Microsoft Windows users expect).
+Microsoft Windows users can turn this feature off with the command-line
+option -noV or by putting
+
+import settings;
+interactiveView=false;
+batchView=false;
+in their config.asy file. See
+https://asymptote.sourceforge.io/doc/Options.html.

+
+File: asy-faq.info, Node: Question 9.2, Next: Question 9.3, Previous: Question 9.1, Up: Section 9
+
+Question 9.2. How do I output jpeg images?
+
+If you have the ImageMagick convert program installed, simply type
+
+asy -f jpg test.asy
+
+File: asy-faq.info, Node: Question 9.3, Next: Question 9.4, Previous: Question 9.2, Up: Section 9
+
+Question 9.3. Can I embed bitmaps (photos) into my drawings and position and scale them?
+
+Convert them to eps format and use the graphic(string) function just like
+a Label:
+
+label(graphic("file"),(0,0));
+See the example https://asymptote.sourceforge.io/gallery/orthocenter.asy
+and https://asymptote.sourceforge.io/doc/label.html.
+
+
+File: asy-faq.info, Node: Question 9.4, Next: Question 9.5, Previous: Question 9.3, Up: Section 9
+
+Question 9.4. Does Asymptote support direct PDF output?
+
+Yes, PDF output can be produced by the -f pdf option or -tex pdflatex
+option. This supports transparency, annotations, embedded movies, and
+U3D/PRC content.
+
+
+File: asy-faq.info, Node: Question 9.5, Next: Question 9.6, Previous: Question 9.4, Up: Section 9
+
+Question 9.5. How to I produce large pictures of high quality in raster format (e.g. png, giff etc).
+
+Try using some of the options to convert, mainly -geometry and -density.
+For example:
+convert -geometry 1000x3000 example.eps example.png
+You can also change the default resolution of the image with:
+convert -geometry 1000x3000 -density 300 -units PixelsPerInch example.eps example.png
+This does not change the number of pixels in the image, but just gives a
+hint as to how large each pixel should be displayed.
+
+If you include the -density option without the -geometry option, convert
+will keep the image size constant (so a 4cm x 3cm eps figure will
+generate a 4cm x 3cm png image).
+
+
+File: asy-faq.info, Node: Question 9.6, Previous: Question 9.5, Up: Section 9
+
+Question 9.6. Is it possible to produce multi-page documents with asymptote?
+
+Yes, simply call the newpage() function. This is used by the slide.asy
+package to produce high-quality slide presentations (easier to use than
+Prosper).

+\begin{enumerate}
+\item Download Asymptote and place the \emph{asymptote-x.xx.src.tgz} file
+on the desktop.
+\item Open Terminal and type the following. Note that you will
+have to enter the root password for the final command.
+\begin{verbatim}
+cd Desktop
+gunzip asymptote-x.xx.src.tgz
+tar -xf asymptote-x.xx.src.tar
+cd asymptote-x.xx
+./configure
+make all
+sudo make install
+\end{verbatim}
+If you get an error at the \verb+./configure+ step, stating that you there
+is \verb+no acceptable C+ \verb+compiler found in $PATH+, a solution
+is to download and install Xcode here: \\
+\verb+http://developer.apple.com/TOOLS/Xcode/+.
+
+\item We now create the engine that will typeset Asymptote in TeXShop. The
+easiest way to create this engine, which we will
+call \emph{asyEngine.engine}, is to navigate
+to \verb+~/Library/TeXShop/Engines+ and duplicate one of the
+existing \emph{.engine} files. Open the duplicate file and delete the code
+there. Type the following:
+\begin{verbatim}
+#!/bin/sh
+location=$(dirname "$1")
+basename="${1%.tex}"
+#process
+cd $location
+pdflatex "$1"
+asy "${basename}"-*.asy
+pdflatex "$1"
+\end{verbatim}
+Save this file as \emph{asyEngine.engine}.
+
+\item Now we set our engine to be executable. In the terminal, navigate to
+the Engines directory and type:
+
+\begin{verbatim}
+chmod +x asyEngine.engine
+\end{verbatim}
+
+\item Finally, in the terminal, type:
+
+\begin{verbatim}
+defaults write TeXShop OtherTeXExtensions -array-add "asy"
+\end{verbatim}
+
+This last command allows you choose the \emph{asyEngine} option from the
+drop-down menu when you wish to typeset a document that includes asymptote.
+\end{enumerate}
+
+Now, if you wish to typeset something simple, like the following red line,
+create a new document in TeXShop and type:
+
+\begin{verbatim}
+\documentclass[letterpaper,12pt]{article}
+\usepackage{amsmath}
+\usepackage{amssymb}
+\usepackage{asymptote}
+
+\begin{document}
+\begin{asy}
+ size(300);
+ draw((0,0)--(1,1),red);
+\end{asy}
+\end{document}
+\end{verbatim}
+
+Choose the \emph{asyEngine} option from the drop-down menu and
+press \emph{Typeset}. Your red line will be created in a PDF Document.
+
+On a final note, it is best to avoid using filenames with spaces in them.
+For example, avoid filenames such as \verb+asy test.tex+ and instead use
+filenames without spaces, such as \verb+asyTest.tex+.
+

+% \begin{abstract}
+% This package provides integration of inline and external Asymptote
+% graphics within a \LaTeX\ document.
+% \end{abstract}
+%
+% \tableofcontents
+%
+% \section{Introduction}
+%
+% This is the documentation for the \LaTeX\ package \texttt{asymptote}
+% which accompanies the Asymptote drawing package. For further details on
+% Asymptote, please see its documentation in \texttt{asymptote.pdf}.
+%
+% \section{User syntax}
+%
+% \subsection{Package loading and options}
+%
+% The package may take two options at load time: \texttt{inline} or
+% \texttt{attach}.
+% These options can also be set at any time with the
+% \cmd\asysetup\marg{options} command, or specified individually in the
+% optional argument to each \texttt{asy} environment or \texttt{asyinclude}
+% command.
+%
+% The \texttt{inline} option uses Asymptote's `inline' mode whereby
+% included graphics have their labels typeset in the environment of the
+% document they are contained within. Otherwise the Asymptote graphics are
+% self-contained and their formatting is independent of the document.
+%
+% The \texttt{attach} option allows generated graphics to be embedded
+% within the PDF using the \texttt{attachfile2} package; please load that
+% package separately if you wish to use it. The \texttt{attach} option
+% takes precedence over the \texttt{inline} option.
+%
+% This package produces quite a number of output files, which by default
+% are created in the same directory as the \LaTeX\ document that is being
+% compiled. To keep things more tidy, you can specify an output directory
+% for these files by defining the \cmd\asydir\ command. For example, if you
+% wish to store the figure files in the subdirectory \texttt{asytmp/}, the
+% you would write \verb|\renewcommand\asydir{asytmp}|.
+%
+% Alternatively (and tentatively), you may write \verb|dir=asytmp| in
+% either the \texttt{asy} environment options or the options to
+% \cmd\asysetup.
+%
+% \subsection{Commands for inserting Asymptote graphics}
+%
+% The main environment defined by the package is the \texttt{asy}
+% environment, in which verbatim Asymptote code is placed that will be
+% compiled for generating a graphic in the document. For example,
+% \begin{verbatim}
+% \begin{figure}
+% \begin{asy}[ <options> ]
+% <ASYMPTOTE CODE>
+% \end{asy}
+% \caption{...}\label{...}
+% \end{verbatim}
+%
+% If you have Asymptote code in a separate file, you can include it with
+% the \cmd\asyinclude\oarg{options}\marg{filename}\ command.
+%
+% For Asymptote code that should be included in \emph{every} graphic,
+% define it using the \texttt{asydef} environment.
+%
+% \subsection{Graphics options}
+%
+% Both the \texttt{asy} environment and the \cmd\asyinclude\ command take
+% optional parameters for controlling aspects of the graphics creation. In
+% addition to locally setting \texttt{inline} and \texttt{attach}, the
+% following options may also be used:
+% \begin{description}
+% \item[width] Width of the figure
+% \item[height] Height of the figure
+% \item[keepAspect] Maintain aspect ratio [default true]
+% \item[viewportwidth] Viewport width for 3D figures
+% \item[viewportheight] Viewport height for 3D figures
+% \end{description}
+% These may also be set globally using the \cmd\asysetup\ command.
+%
+% \section{Processing the document}
+%
+% After running \LaTeX\ on the document, it is necessary to process the
+% Asymptote graphics so they can be included in the next compilation. The
+% simplest procedure is a recipe such as
+% \begin{verbatim}
+% pdflatex mydoc
+% asy mydoc-*.asy
+% pdflatex mydoc
+% \end{verbatim}
+% This technique will recompile each graphic every time, however. To only
+% recompile graphics that have changed, use the \texttt{latexmk}
+% tool. Asymptote is distributed with a \texttt{latexmkrc} configuration
+% file; place this file in a place where \texttt{latexmk} will find it and
+% your document may be compiled, including the \texttt{asy} compilations,
+% with \texttt{latexmk mydoc} or \texttt{latexmk --pdf mydoc}.

+% So load \textsf{ifpdf} and \textsf{ifxetex} if they exist; otherwise,
+% emulate them.
+%
+% In due course, delete this code and just load the packages.

+.SH NAME
+asy \- Asymptote: a script-based vector graphics language
+.SH SYNOPSIS
+.B asy
+.RI [ options ]
+.RI [ file \ ...]
+.SH DESCRIPTION
+\fBAsymptote\fP is a powerful descriptive vector graphics language for
+technical drawings, inspired by MetaPost but with an improved C++-like syntax.
+Asymptote provides for figures the same high-quality level of typesetting that
+LaTeX does for scientific text.
+.SH OPTIONS
+If no arguments are given, Asymptote runs in interactive mode.
+.PP
+If "\-" is given as the file argument, Asymptote reads from standard input.
+.PP
+A summary of options is included below. The effect of most options
+can be negated by prepending
+.B no
+to the option name.
+Default values for most options may also be entered in the
+file
+.B .asy/config.asy
+in the user's home directory using the long form:
+.PP
+ import settings;
+ batchView=true;

+.SH SYNOPSIS
+.B asy
+.RI [ options ]
+.RI [ file \ ...]
+.SH DESCRIPTION
+\fBAsymptote\fP is a powerful descriptive vector graphics language for
+technical drawings, inspired by MetaPost but with an improved C++-like syntax.
+Asymptote provides for figures the same high-quality level of typesetting that
+LaTeX does for scientific text.
+.SH OPTIONS
+If no arguments are given, Asymptote runs in interactive mode.
+.PP
+If "\-" is given as the file argument, Asymptote reads from standard input.
+.PP
+A summary of options is included below. The effect of most options
+can be negated by prepending
+.B no
+to the option name.
+Default values for most options may also be entered in the
+file
+.B .asy/config.asy
+in the user's home directory using the long form:
+.PP
+ import settings;
+ batchView=true;
+.PP
+For a complete
+description, see the Info files.

+% This file can be printed with 1, 2, or 3 columns per page (see below).
+% [For 2 or 3 columns, you'll need 6 and 8 point fonts.]
+% Specify how many you want here. Nothing else needs to be changed.

+% but WITHOUT ANY WARRANTY; without even the implied warranty of

+
+% This file is intended to be processed by plain TeX (TeX82).
+%
+% The final reference card has six columns, three on each side.
+% This file can be used to produce it in any of three ways:
+% 1 column per page
+% produces six separate pages, each of which needs to be reduced to 80%.
+% This gives the best resolution.
+% 2 columns per page
+% produces three already-reduced pages.
+% You will still need to cut and paste.
+% 3 columns per page
+% produces two pages which must be printed sideways to make a
+% ready-to-use 8.5 x 11 inch reference card.
+% For this you need a dvi device driver that can print sideways.
+% Which mode to use is controlled by setting \columnsperpage above.

+@cindex @code{Asymptote Web Application}
+@code{Asymptote} is a powerful descriptive vector graphics language that
+provides a mathematical coordinate-based framework for technical drawing.
+Labels and equations are typeset with @code{LaTeX}, for overall document
+consistency, yielding the same high-quality level of typesetting that
+@code{LaTeX} provides for scientific text. By default it produces
+@code{PostScript} output, but it can also generate @code{PDF},
+@code{SVG}, @code{WebGL}, @code{PRC}, and any format that the
+@code{ImageMagick} package can produce. You can even try it out in your
+Web browser without installing it, using the @code{Asymptote Web
+Application}:
+
+@url{http://asymptote.ualberta.ca}
+
+A major advantage of @code{Asymptote} over other graphics packages is
+that it is a high-level programming language, as opposed to just a graphics
+program: it can therefore exploit the best features of the script
+(command-driven) and graphical-user-interface (@acronym{GUI}) methods for
+producing figures. The rudimentary @acronym{GUI} @code{xasy} included with the
+package allows one to move script-generated objects
+around. To make @code{Asymptote} accessible to the average user, this
+@acronym{GUI} is currently being developed into a full-fledged interface
+that can generate objects directly. However, the script portion of the language
+is now ready for general use by users who are willing to learn a few
+simple @code{Asymptote} graphics commands (@pxref{Drawing commands}).
+
+@code{Asymptote} is mathematically oriented (e.g.@ one can
+use complex multiplication to rotate a vector) and uses
+@code{LaTeX} to do the
+typesetting of labels. This is an important feature for scientific
+applications. It was inspired by an earlier drawing program (with a weaker
+syntax and capabilities) called @code{MetaPost}.
+
+The @code{Asymptote} vector graphics language provides:
+
+@itemize @bullet
+@item a standard for typesetting mathematical figures, just
+as @TeX{}/@code{LaTeX} is the de-facto standard for typesetting equations.
+
+@item @code{LaTeX} typesetting of labels, for overall document consistency;
+
+@item the ability to generate and embed 3D vector @acronym{WebGL}
+graphics within @acronym{HTML} files;
+
+@item the ability to generate and embed 3D vector @acronym{PRC}
+graphics within @acronym{PDF} files;
+
+@item a natural coordinate-based framework for technical drawing,
+inspired by @code{MetaPost}, with a much cleaner, powerful C++-like programming
+syntax;
+
+@item compilation of figures into virtual machine code for speed, without
+sacrificing portability;
+
+@item the power of a script-based language coupled to the convenience of
+a @acronym{GUI};
+
+@item customization using its own C++-like graphics programming language;
+
+@item sensible defaults for graphical features, with the ability to override;
+
+@item a high-level mathematically oriented interface to the
+@code{PostScript} language for vector graphics, including affine transforms
+and complex variables;
+
+@item functions that can create new (anonymous) functions;
+
+@item deferred drawing that uses the simplex method to solve overall size
+constraint issues between fixed-sized objects (labels and arrowheads) and
+objects that should scale with figure size;
+
+@end itemize
+
+Many of the features of @code{Asymptote} are written in the
+@code{Asymptote} language itself. While the stock version of
+@code{Asymptote} is designed for mathematics typesetting needs, one can
+write @code{Asymptote} modules that tailor it to specific
+applications; for example, a scientific graphing module is available
+(@pxref{graph}). Examples of @code{Asymptote} code and output,
+including animations, are available at

+where @code{x.xx} denotes the latest version.
+
+A working @TeX{} implementation (we recommend

+@cindex configuring
+@cindex @code{-V}
+In interactive mode, or when given the @code{-V} option (the default
+when running @code{Asymptote} on a single file under @code{MSDOS}),
+@code{Asymptote} will automatically invoke the @code{PostScript}
+viewer @code{gv} (under @code{UNIX}) or @code{gsview} (under
+@code{MSDOS} to display graphical output.
+The @code{PostScript} viewer should be capable of automatically
+redrawing whenever the output file is updated. The default @code{UNIX}
+@code{PostScript} viewer @code{gv} supports this (via a @code{SIGHUP}
+signal). Version @code{gv-3.6.3} or later (from
+@url{https://ftp.gnu.org/gnu/gv/}) is required for interactive mode to
+work properly.
+Users of @code{ggv} will need to enable @code{Watch file} under
+@code{Edit/PostScript Viewer Preferences}.
+Users of @code{gsview} will need to enable @code{Options/Auto Redisplay}
+(however, under @code{MSDOS} it is still necessary to click on the
+@code{gsview} window; under @code{UNIX} one must manually redisplay by
+pressing the @code{r} key).

+@cindex configuration file
+Configuration variables are most easily set as @code{Asymptote}
+variables in an optional configuration file @code{config.asy}
+@pxref{configuration file}).
+For example, the setting @code{pdfviewer} specifies the location of
+the @acronym{PDF} viewer. Here are the default values of several
+important configuration variables under @code{UNIX}:
+
+@noindent
+@verbatim
+import settings;
+pdfviewer="acroread";
+htmlviewer="google-chrome";
+psviewer="gv";
+display="display";
+animate="animate";
+gs="gs";
+libgs="";
+@end verbatim
+
+@noindent
+@cindex @code{cmd}
+Under @code{MSDOS}, the viewer settings
+@code{htmlviewer}, @code{pdfviewer}, @code{psviewer},
+@code{display}, and @code{animate} default to the string @code{cmd},
+requesting the application normally associated with each file type.
+The (installation-dependent) default values of @code{gs}
+and @code{libgs} are determined automatically from the @code{Microsoft
+Windows} registry. The @code{gs} setting specifies the location of the
+@code{PostScript} processor @code{Ghostscript}, available from
+@url{https://www.ghostscript.com/}.
+
+@noindent
+@cindex @code{htmlviewer}
+@cindex @code{absolute}
+The configuration variable @code{htmlviewer} specifies the
+browser to use to display 3D @code{WebGL} output.
+The default setting is @code{google-chrome} under @code{UNIX} and
+@code{cmd} under @code{Microsoft Windows}. Note that @code{Internet Explorer}
+does not support @code{WebGL}; @code{Microsoft Windows} users should set their
+default html browser to @code{chrome} or @code{microsoft-edge}.
+By default, 2D and 3D @code{HTML} images expand to the enclosing canvas;
+this can be disabled by setting the configuation variable @code{absolute}
+to @code{true}.
+
+On @code{UNIX} systems, to support automatic document
+reloading of @code{PDF} files in @code{Adobe Reader}, we recommend
+copying the file @code{reload.js} from the @code{Asymptote} system
+directory (by default, @code{@value{Datadir}/asymptote} under @code{UNIX} to
+@code{~/.adobe/Acrobat/x.x/JavaScripts/},
+where @code{x.x} represents the appropriate @code{Adobe Reader}
+version number. The automatic document reload feature must then be
+explicitly enabled by putting
+@verbatim
+import settings;
+pdfreload=true;
+pdfreloadOptions="-tempFile";
+@end verbatim
+@noindent
+in the @code{Asymptote} configuration file. This reload feature is not
+useful under @code{MSDOS} since the document cannot be updated anyway on
+that operating system until it is first closed by @code{Adobe Reader}.
+
+The configuration variable @code{dir} can be used to adjust the
+search path (@pxref{Search paths}).
+
+@cindex @code{papertype}
+@cindex @code{paperwidth}
+@cindex @code{paperheight}
+@cindex @code{letter}
+@cindex @code{a4}
+By default, @code{Asymptote} attempts to center the figure on the
+page, assuming that the paper type is @code{letter}. The default paper
+type may be changed to @code{a4} with the configuration variable
+@code{papertype}. Alignment to other paper sizes can be obtained by setting the
+configuration variables @code{paperwidth} and @code{paperheight}.

+
+Warnings (such as "unbounded" and "offaxis") may be enabled or disabled with
+the functions
+@verbatim

+@noindent
+or by directly modifying the string array @code{settings.suppress}, which lists

+@verbatiminclude diagonal.asy
+
+@noindent
+Then execute the command
+@verbatim

+@end verbatim
+@noindent
+Alternatively, @code{MSDOS} users can drag and drop @code{test.asy} onto the

+application for the extension @code{asy}).
+
+@noindent
+@cindex @code{-V}
+This method, known as @emph{batch mode}, outputs a @code{PostScript}

+@cindex @code{size}
+@cindex @code{pair}
+In @code{Asymptote}, coordinates like @code{(0,0)} and @code{(100,100)},
+called @emph{pairs},
+are expressed in @code{PostScript} "big points" (1 @code{bp} = 1/72
+@code{inch}) and the default line width is @code{0.5bp}.
+However, it is often inconvenient to work directly in
+@code{PostScript} coordinates.
+The next example produces identical output to the previous example, by
+scaling the line @code{(0,0)--(1,1)} to fit a rectangle of width
+@code{100.5 bp} and height @code{100.5 bp} (the extra @code{0.5bp}
+accounts for the line width):

+One can also specify the size in @code{pt} (1 @code{pt} = 1/72.27 @code{inch}),
+@code{cm}, @code{mm}, or @code{inches}.
+Two nonzero size arguments (or a single size argument) restrict the
+size in both directions, preserving the aspect ratio.
+If 0 is given as a size argument, no restriction is made in that direction;
+the overall scaling will be determined by the other direction (@pxref{size}):

+@cindex @code{cycle}
+To connect several points and create a cyclic path, use the

+@sp 1
+@center @image{./square}
+@noindent
+For convenience, the path @code{(0,0)--(1,0)--(1,1)--(0,1)--cycle}

+@node Labels, Paths, Figure size, Tutorial
+@section Labels

+which along with the directions @code{up}, @code{down}, @code{right},
+and @code{left} are defined as pairs in the @code{Asymptote} base
+module @code{plain} (a user who has a local variable named @code{E}
+may access the compass direction @code{E} by prefixing it with the name
+of the module where it is defined: @code{plain.E}).
+
+@node Paths, , Labels, Tutorial
+@section Paths
+@cindex @code{path}
+This example draws a path that approximates a quarter circle,
+terminated with an arrowhead:
+@verbatiminclude quartercircle.asy
+@sp 1
+@center @image{./quartercircle}
+@noindent
+Here the directions @code{up} and @code{left} in braces specify the
+outgoing and incoming directions at the points @code{(1,0)} and
+@code{(0,1)}, respectively.
+
+In general, a path is specified as a list of points (or other paths)
+interconnected with
+@cindex @code{cycle}
+@cindex @code{--}
+@cindex @code{..}
+@code{--}, which denotes a straight line segment, or @code{..}, which
+denotes a cubic spline (@pxref{Bezier curves}).
+@cindex @code{unitcircle}
+@anchor{unitcircle}
+@cindex @code{unitcircle}
+Specifying a final @code{..cycle} creates a cyclic path that
+connects smoothly back to the initial node, as in this approximation
+(accurate to within 0.06%) of a unit circle:
+@verbatim
+path unitcircle=E..N..W..S..cycle;
+@end verbatim
+
+@cindex @code{PostScript} subpath
+@cindex @code{^^}
+@cindex @code{path[]}
+@cindex superpath
+@noindent
+An @code{Asymptote} path, being connected, is equivalent to a
+@code{PostScript subpath}. The @code{^^} binary operator, which
+requests that the pen be moved (without drawing or affecting
+endpoint curvatures) from the final point of the left-hand path to the
+initial point of the right-hand path, may be used to group several
+@code{Asymptote} paths into a @code{path[]} array (equivalent to a
+@code{PostScript} path):
+@verbatiminclude superpath.asy
+@sp 1
+@center @image{./superpath}
+
+@cindex evenodd
+@noindent
+The @code{PostScript} even-odd fill rule here specifies that only the
+region bounded between the two unit circles is filled (@pxref{fillrule}).
+In this example, the same effect can be achieved by using the default
+zero winding number fill rule, if one is careful to alternate the
+orientation of the paths:
+@verbatim
+filldraw(unitcircle^^reverse(g),yellow,black);
+@end verbatim
+
+@cindex @code{unitbox}
+The @code{^^} operator is used by the @code{box(triple, triple)} function in
+the module @code{three} to construct the edges of a
+cube @code{unitbox} without retracing steps (@pxref{three}):

+@chapter Drawing commands
+@cindex drawing commands
+
+All of @code{Asymptote}'s graphical capabilities are based on four primitive
+commands. The three @code{PostScript} drawing commands @code{draw},
+@code{fill}, and @code{clip} add objects to a picture in the order in
+which they are executed, with the most recently drawn object appearing on top.
+The labeling command @code{label} can be used to add text
+labels and external @acronym{EPS} images, which will appear on top of the
+@code{PostScript} objects (since this is normally what one wants), but
+again in the relative order in which they were executed. After drawing
+objects on a picture, the picture can be output with the
+@code{shipout} function (@pxref{shipout}).
+
+@cindex @code{layer}
+If you wish to draw @code{PostScript} objects on top of labels (or verbatim
+@code{tex} commands; @pxref{tex}), the @code{layer} command may be
+used to start a
+new @code{PostScript/LaTeX} layer:
+@verbatim
+void layer(picture pic=currentpicture);
+@end verbatim
+
+The @code{layer} function gives one full control over the order in which
+objects are drawn. Layers are drawn sequentially, with the most recent
+layer appearing on top. Within each layer, labels, images, and
+verbatim @code{tex} commands are always drawn after the
+@code{PostScript} objects in that layer.
+
+@cindex @code{newpage}
+A page break can be generated with the command
+@verbatim
+void newpage(picture pic=currentpicture);
+@end verbatim
+
+While some of these drawing commands take many options, they all have sensible
+default values (for example, the picture argument defaults to
+currentpicture).

+(which draws no arrows or path), @code{BeginArrow}, @code{MidArrow},
+@code{EndArrow} (or equivalently @code{Arrow}),
+and @code{Arrows} (which draws an arrow at both ends of the path).
+All of the arrow specifiers except for @code{None} and @code{Blank}
+may be given the optional arguments arrowhead @code{arrowhead} (one of
+the predefined arrowhead styles @code{DefaultHead}, @code{SimpleHead},
+@code{HookHead}, @code{TeXHead}),

+@cindex @code{DotMargins}
+@cindex @code{Margin}
+@cindex @code{TrueMargin}
+Margins can be used to shrink the visible portion of a path by
+@code{labelmargin(p)} to avoid overlap with other drawn objects.
+Typical values of @code{margin}
+are @code{NoMargin}, @code{BeginMargin}, @code{EndMargin} (or
+equivalently @code{Margin}), and @code{Margins} (which leaves a margin
+at both ends of the path). One may use
+@code{Margin(real begin, real end=begin)}
+to specify the size of the beginning and ending margin, respectively,
+in multiples of the units @code{labelmargin(p)} used for aligning labels.
+Alternatively, @code{BeginPenMargin}, @code{EndPenMargin}
+(or equivalently @code{PenMargin}), @code{PenMargins},
+@code{PenMargin(real begin, real end=begin)} specify a margin in units of
+the pen line width, taking account of the pen line width when drawing
+the path or arrow. For example, use @code{DotMargin}, an
+abbreviation for @code{PenMargin(-0.5*dotfactor,0.5*dotfactor)},
+to draw from the usual beginning point just up to the boundary of an
+end dot of width @code{dotfactor*linewidth(p)}. The qualifiers
+@code{BeginDotMargin}, @code{EndDotMargin}, and @code{DotMargins} work
+similarly. The qualifier @code{TrueMargin(real begin, real end=begin)}
+allows one to specify a margin directly in @code{PostScript} units,
+independent of the pen line width.
+
+The use of arrows, bars, and margins is illustrated by the examples
+@code{@uref{https://asymptote.sourceforge.io/gallery/Pythagoras.svg,,Pythagoras}@uref{https://asymptote.sourceforge.io/gallery/Pythagoras.asy,,.asy}} and

+The legend for a picture @code{pic} can be fit and aligned to a frame
+with the routine:
+@cindex @code{legend}
+@verbatim
+frame legend(picture pic=currentpicture, int perline=1,
+ real xmargin=legendmargin, real ymargin=xmargin,
+ real linelength=legendlinelength,
+ real hskip=legendhskip, real vskip=legendvskip,
+ real maxwidth=0, real maxheight=0,
+ bool hstretch=false, bool vstretch=false, pen p=currentpen);
+@end verbatim
+@noindent
+Here @code{xmargin} and @code{ymargin} specify the surrounding @math{x}
+and @math{y} margins, @code{perline} specifies the number of entries
+per line (default 1; 0 means choose this number automatically),
+@code{linelength} specifies the length of the path lines, @code{hskip}
+and @code{vskip} specify the line skip (as a multiple of the legend entry
+size), @code{maxwidth} and @code{maxheight} specify optional upper limits
+on the width and height of the resulting legend (0 means unlimited),
+@code{hstretch} and @code{vstretch} allow the legend to stretch
+horizontally or vertically, and @code{p} specifies the pen used to draw
+the bounding box. The legend frame can then be added and aligned about a
+point on a picture @code{dest} using @code{add} or @code{attach}
+(@pxref{add about}).
+
+@cindex @code{dot}
+To draw a dot, simply draw a path containing a single point.
+The @code{dot} command defined in the module @code{plain} draws a
+dot having a diameter equal to an explicit pen line width or the
+default line width magnified by @code{dotfactor} (6 by default),
+using the specified filltype (@pxref{filltype}) or @code{dotfilltype}
+(@code{Fill} by default):
+@verbatim
+void dot(frame f, pair z, pen p=currentpen, filltype filltype=dotfilltype);
+void dot(picture pic=currentpicture, pair z, pen p=currentpen,
+ filltype filltype=dotfilltype);
+void dot(picture pic=currentpicture, Label L, pair z, align align=NoAlign,
+ string format=defaultformat, pen p=currentpen, filltype filltype=dotfilltype);

+ filltype filltype=dotfilltype);
+void dot(picture pic=currentpicture, Label L, pen p=currentpen,
+ filltype filltype=dotfilltype);
+@end verbatim
+
+@cindex @code{Label}
+If the variable @code{Label} is given as the @code{Label}
+argument to the third routine, the @code{format} argument will be
+used to format a string based on the dot location (here @code{defaultformat}
+is @code{"$%.4g$"}).
+The fourth routine draws a dot at every point of a pair array @code{z}.
+One can also draw a dot at every node of a path:
+@verbatim
+void dot(picture pic=currentpicture, Label[] L=new Label[],
+ explicit path g, align align=RightSide, string format=defaultformat,
+ pen p=currentpen, filltype filltype=dotfilltype);
+@end verbatim
+See @ref{pathmarkers} and @ref{markers} for more general
+methods for marking path nodes.
+
+To draw a fixed-sized object (in @code{PostScript} coordinates) about
+the user coordinate @code{origin}, use the routine
+@cindex @code{draw}
+@verbatim
+void draw(pair origin, picture pic=currentpicture, Label L="", path g,
+ align align=NoAlign, pen p=currentpen, arrowbar arrow=None,

+ pen drawpen=currentpen);
+@end verbatim
+
+@cindex @code{fill}

+@verbatim
+void fill(pair origin, picture pic=currentpicture, path g, pen p=currentpen);
+@end verbatim

+void tensorshade(picture pic=currentpicture, path[] g, bool stroke=false,
+ pen fillrule=currentpen, pen[][] p, path[] b=g,
+ pair[][] z=new pair[][]);
+@end verbatim
+@noindent
+If the array @code{z} is empty, Coons shading, in which the color
+control points are calculated automatically, is used.
+The pens in @code{p} must belong to the same color space.
+A simpler interface for the case of a single patch (@math{n=1}) is also
+available:
+@verbatim
+void tensorshade(picture pic=currentpicture, path g, bool stroke=false,
+ pen fillrule=currentpen, pen[] p, path b=g,
+ pair[] z=new pair[]);
+@end verbatim
+One can also smoothly shade the regions between consecutive paths of a
+sequence using a given array of pens:
+@verbatim
+void draw(picture pic=currentpicture, pen fillrule=currentpen, path[] g,
+ pen[] p);
+@end verbatim
+@noindent
+Illustrations of tensor product and Coons shading are provided in the

+@cindex Function shading
+@cindex function shading
+@cindex @code{functionshade}
+More general shading possibilities are available using @TeX{} engines
+that produce PDF output (@pxref{texengines}): the routine
+@verbatim
+void functionshade(picture pic=currentpicture, path[] g, bool stroke=false,
+ pen fillrule=currentpen, string shader);
+@end verbatim
+@noindent
+shades on picture @code{pic} the interior of path @code{g} according
+to fill rule @code{fillrule} using the @code{PostScript} calculator routine
+specified by the string @code{shader}; this routine takes 2 arguments,
+each in [0,1], and returns @code{colors(fillrule).length} color components.
+Function shading is illustrated in the example @code{@uref{https://asymptote.sourceforge.io/gallery/functionshading.pdf,,functionshading}@uref{https://asymptote.sourceforge.io/gallery/functionshading.asy,,.asy}}.
+
+@cindex unfill
+The following routine uses @code{evenodd} clipping together with the
+@code{^^} operator to unfill a region:
+
+@verbatim
+void unfill(picture pic=currentpicture, path g);
+@end verbatim
+
+@node clip, label, fill, Drawing commands
+@section clip
+@cindex @code{clip}
+@cindex @code{stroke}
+@verbatim
+void clip(picture pic=currentpicture, path g, stroke=false,
+ pen fillrule=currentpen);
+@end verbatim
+
+Clip the current contents of picture @code{pic} to the region bounded
+by the path @code{g}, using fill rule @code{fillrule} (@pxref{fillrule}).
+If @code{stroke=true}, the clipped portion is the same as the region
+that would be drawn with @code{draw(pic,g,zerowinding)}; in
+this case the path @code{g} need not be cyclic. While clipping has no notion
+of depth (it transcends layers and even pages), one can localize clipping
+to a temporary picture, which can then be added to @code{pic}.
+For an illustration of picture clipping, see the first example in @ref{LaTeX usage}.
+
+@node label, , clip, Drawing commands
+@section label
+@cindex @code{label}
+@verbatim
+void label(picture pic=currentpicture, Label L, pair position,
+ align align=NoAlign, pen p=currentpen, filltype filltype=NoFill)
+@end verbatim
+
+Draw Label @code{L} on picture @code{pic} using pen @code{p}. If
+@code{align} is @code{NoAlign}, the label will be centered at user
+coordinate @code{position}; otherwise it will be aligned in the
+direction of @code{align} and displaced from @code{position} by
+the @code{PostScript} offset @code{align*labelmargin(p)}.
+@cindex @code{Align}
+The constant @code{Align} can be used to align the
+bottom-left corner of the label at @code{position}.
+@cindex @code{nullpen}
+@cindex @code{Label}
+@anchor{Label}
+The Label @code{L} can either be a string or the structure obtained by calling
+one of the functions
+@verbatim
+Label Label(string s="", pair position, align align=NoAlign,
+ pen p=nullpen, embed embed=Rotate, filltype filltype=NoFill);
+Label Label(string s="", align align=NoAlign,
+ pen p=nullpen, embed embed=Rotate, filltype filltype=NoFill);
+Label Label(Label L, pair position, align align=NoAlign,
+ pen p=nullpen, embed embed=L.embed, filltype filltype=NoFill);
+Label Label(Label L, align align=NoAlign,
+ pen p=nullpen, embed embed=L.embed, filltype filltype=NoFill);
+@end verbatim
+The text of a Label can be scaled, slanted, rotated, or shifted by
+multiplying it on the left by an affine transform (@pxref{Transforms}).
+For example, @code{rotate(45)*xscale(2)*L} first scales @code{L} in the
+@math{x} direction and then rotates it counterclockwise by 45
+degrees. The final position of a Label can also be shifted by a
+@code{PostScript} coordinate translation: @code{shift(10,0)*L}.
+An explicit pen specified within the Label overrides other pen arguments.
+The @code{embed} argument determines how the Label should transform with the
+embedding picture:
+@table @code
+@item Shift
+@cindex @code{Shift}
+only shift with embedding picture;
+
+@item Rotate
+@cindex @code{Rotate}
+only shift and rotate with embedding picture (default);
+
+@item Rotate(pair z)
+@cindex @code{Rotate(pair z)}
+rotate with (picture-transformed) vector @code{z}.
+
+@item Slant
+@cindex @code{Slant}
+only shift, rotate, slant, and reflect with embedding picture;
+
+@item Scale
+@cindex @code{Scale}
+shift, rotate, slant, reflect, and scale with embedding picture.
+
+@end table
+
+To add a label to a path, use
+@verbatim
+void label(picture pic=currentpicture, Label L, path g, align align=NoAlign,
+ pen p=currentpen, filltype filltype=NoFill);
+@end verbatim
+@cindex @code{Relative}
+By default the label will be positioned at the midpoint of the path.
+An alternative label position (in the sense of @code{point(path p, real t)})
+may be specified as a real value for @code{position} in constructing
+the Label. The position @code{Relative(real)} specifies a location
+relative to the total arclength of the path. These convenient
+abbreviations are predefined:
+@cindex @code{BeginPoint}
+@cindex @code{MidPoint}
+@cindex @code{EndPoint}
+@verbatim
+position BeginPoint=Relative(0);
+position MidPoint=Relative(0.5);
+position EndPoint=Relative(1);
+@end verbatim
+
+@cindex @code{Relative}
+@cindex @code{LeftSide}
+@cindex @code{Center}
+@cindex @code{RightSide}
+Path labels are aligned in the direction @code{align}, which may
+be specified as an absolute compass direction (pair) or a direction
+@code{Relative(pair)} measured relative to a north axis
+in the local direction of the path. For convenience @code{LeftSide},
+@code{Center}, and @code{RightSide} are defined as @code{Relative(W)},
+@code{Relative((0,0))}, and @code{Relative(E)}, respectively.
+Multiplying @code{LeftSide} and @code{RightSide} on the
+left by a real scaling factor will move the label further away from or
+closer to the path.
+
+A label with a fixed-size arrow of length @code{arrowlength} pointing
+to @code{b} from direction @code{dir} can be produced with the routine
+@cindex @code{arrow}
+@verbatim
+void arrow(picture pic=currentpicture, Label L="", pair b, pair dir,
+ real length=arrowlength, align align=NoAlign,
+ pen p=currentpen, arrowbar arrow=Arrow, margin margin=EndMargin);
+@end verbatim
+If no alignment is specified (either in the Label or as an explicit
+argument), the optional Label will be aligned in the direction @code{dir},
+using margin @code{margin}.
+
+@cindex including images
+@cindex @code{graphic}
+@cindex @acronym{EPS}
+The function @code{string graphic(string name, string options="")}
+returns a string that can be used to include an encapsulated
+@code{PostScript} (@acronym{EPS}) file. Here, @code{name} is the name
+of the file to include and @code{options} is a string containing a
+comma-separated list of optional bounding box (@code{bb=llx lly urx
+ury}), width (@code{width=value}), height (@code{height=value}),
+rotation (@code{angle=value}), scaling (@code{scale=factor}), clipping
+(@code{clip=bool}), and draft mode (@code{draft=bool}) parameters. The
+@code{layer()} function can be used to force future objects to be
+drawn on top of the included image:
+@verbatim
+label(graphic("file.eps","width=1cm"),(0,0),NE);
+layer();
+@end verbatim
+
+@cindex @code{baseline}
+The @code{string baseline(string s, string template="\strut")}
+function can be used to enlarge the bounding box of labels to match a
+given template, so that their baselines will be typeset on a
+horizontal line. See @code{@uref{https://asymptote.sourceforge.io/gallery/Pythagoras.svg,,Pythagoras}@uref{https://asymptote.sourceforge.io/gallery/Pythagoras.asy,,.asy}} for an example.
+
+One can prevent labels from overwriting one another with the
+@code{overwrite} pen attribute (@pxref{overwrite}).
+
+The structure @code{object} defined in @code{plain_Label.asy}
+allows Labels and frames to be treated in a uniform manner.
+A group of objects may be packed together into single frame with the routine
+@cindex @code{pack}
+@verbatim
+frame pack(pair align=2S ... object inset[]);
+@end verbatim
+@noindent
+To draw or fill a box (or ellipse or other path) around a Label and
+return the bounding object, use one of the routines
+@verbatim
+object draw(picture pic=currentpicture, Label L, envelope e,
+ real xmargin=0, real ymargin=xmargin, pen p=currentpen,
+ filltype filltype=NoFill, bool above=true);
+object draw(picture pic=currentpicture, Label L, envelope e, pair position,
+ real xmargin=0, real ymargin=xmargin, pen p=currentpen,
+ filltype filltype=NoFill, bool above=true);
+@end verbatim
+@noindent
+Here @code{envelope} is a boundary-drawing routine such as @code{box},
+@code{roundbox}, or @code{ellipse} defined in @code{plain_boxes.asy}
+(@pxref{envelope}).
+
+@cindex @code{texpath}
+The function @code{path[] texpath(Label L)} returns the path array that
+@TeX{} would fill to draw the Label @code{L}.
+
+@cindex @code{minipage}
+The @code{string minipage(string s, width=100pt)} function can be used
+to format string @code{s} into a paragraph of width @code{width}.
+This example uses @code{minipage}, @code{clip}, and @code{graphic} to
+produce a CD label:

+@chapter Bezier curves
+@cindex Bezier curves
+@cindex direction specifier
+Each interior node of a cubic spline may be given a
+direction prefix or suffix @code{@{dir@}}: the direction of the pair
+@code{dir} specifies the direction of the incoming or outgoing tangent,
+respectively, to the curve at that node. Exterior nodes may be
+given direction specifiers only on their interior side.
+
+A cubic spline between the node @math{z_0}, with postcontrol point
+@math{c_0}, and the node @math{z_1}, with precontrol point @math{c_1},
+is computed as the Bezier curve
+@sp 1
+@center @image{./bezier,,,(1-t)^3*z_0+3t(1-t)^2*c_0+3t^2(1-t)*c_1+t^3*z_1 for 0 <=t <= 1.}
+
+As illustrated in the diagram below, the third-order midpoint (@math{m_5})
+constructed from two endpoints @math{z_0} and @math{z_1} and two control points
+@math{c_0} and @math{c_1}, is the point corresponding to @math{t=1/2} on
+the Bezier curve formed by the quadruple (@math{z_0}, @math{c_0},
+@math{c_1}, @math{z_1}). This allows one to recursively construct the
+desired curve, by using the newly extracted third-order midpoint as an
+endpoint and the respective second- and first-order midpoints as control
+points:
+@sp 1
+@center @image{./bezier2}
+
+Here @math{m_0}, @math{m_1} and @math{m_2} are the first-order
+midpoints, @math{m_3} and @math{m_4} are the second-order midpoints, and
+@math{m_5} is the third-order midpoint.
+The curve is then constructed by recursively applying the algorithm to
+(@math{z_0}, @math{m_0}, @math{m_3}, @math{m_5}) and
+(@math{m_5}, @math{m_4}, @math{m_2}, @math{z_1}).
+
+In fact, an analogous property holds for points located at any
+fraction @math{t} in @math{[0,1]} of each segment, not just for
+midpoints (@math{t=1/2}).
+
+The Bezier curve constructed in this manner has the following properties:
+@itemize @bullet
+
+@item It is entirely contained in the convex hull of the given four points.
+
+@item It starts heading from the first endpoint to the first control point
+and finishes heading from the second control point to the second endpoint.
+
+@end itemize
+
+@cindex @code{controls}
+The user can specify explicit control points between two nodes like this:
+@verbatim
+draw((0,0)..controls (0,100) and (100,100)..(100,0));
+@end verbatim
+
+However, it is usually more convenient to just use the
+@code{..} operator, which tells @code{Asymptote} to choose its own
+control points using the algorithms described in Donald Knuth's
+monograph, The MetaFontbook, Chapter 14.
+The user can still customize the guide (or path) by specifying
+direction, tension, and curl values.
+
+The higher the tension, the straighter the curve is, and the more
+it approximates a straight line.
+@cindex @code{tension}
+@cindex @code{and}
+@cindex @code{atleast}
+One can change the spline tension from its default value of 1 to any
+real value greater than or equal to 0.75 (cf. John D. Hobby, Discrete and
+Computational Geometry 1, 1986):
+@verbatim
+draw((100,0)..tension 2 ..(100,100)..(0,100));
+draw((100,0)..tension 3 and 2 ..(100,100)..(0,100));
+draw((100,0)..tension atleast 2 ..(100,100)..(0,100));
+@end verbatim
+
+In these examples there is a space between @code{2} and @code{..}.
+This is needed as @code{2.} is interpreted as a numerical constant.
+
+@cindex @code{curl}
+The curl parameter specifies the curvature at the endpoints of a path
+(0 means straight; the default value of 1 means approximately circular):
+@verbatim
+draw((100,0){curl 0}..(100,100)..{curl 0}(0,100));
+@end verbatim
+
+@cindex @code{MetaPost ...@ }
+@cindex @code{::}
+The @code{MetaPost ...} path connector, which requests, when possible, an
+inflection-free curve confined to a triangle defined by the
+endpoints and directions, is implemented in @code{Asymptote} as the
+convenient abbreviation @code{::} for @code{..tension atleast 1 ..}
+(the ellipsis @code{...} is used in @code{Asymptote} to indicate a
+variable number of arguments; @pxref{Rest arguments}). For example,
+compare
+@verbatiminclude dots.asy
+@sp 1
+@center @image{./dots}
+@noindent
+with
+@verbatiminclude colons.asy
+@sp 1
+@center @image{./colons}
+
+@cindex @code{---}
+@cindex @code{&}
+The @code{---} connector is an abbreviation for @code{..tension atleast
+infinity..} and the @code{&} connector concatenates two paths, after
+first stripping off the last node of the first path (which normally
+should coincide with the first node of the second path).

+with those of C, C++, and Java:
+@cindex declaration

+@cindex @code{for}
+@verbatim

+
+@end verbatim
+
+@cindex @code{while}
+@cindex @code{do}
+@cindex @code{break}

+@code{Asymptote} supports @code{while}, @code{do}, @code{break}, and

+In addition, it supports many features beyond the ones found in those
+languages.
+
+@node Data types, Paths and guides, Programming, Programming
+@section Data types
+@cindex data types
+@code{Asymptote} supports the following data types (in addition to
+user-defined types):
+
+@table @code
+
+@item void
+@cindex @code{void}
+The void type is used only by functions that take or return no arguments.
+
+@item bool
+@cindex @code{bool}
+a boolean type that can only take on the values @code{true} or
+@code{false}. For example:
+@verbatim
+bool b=true;
+@end verbatim
+
+@noindent
+defines a boolean variable @code{b} and initializes it to the value
+@code{true}. If no initializer is given:
+@verbatim
+bool b;
+@end verbatim
+
+@noindent
+the value @code{false} is assumed.
+
+@item bool3
+@cindex @code{bool3}
+an extended boolean type that can take on the values
+@code{true}, @code{default}, or @code{false}. A bool3 type can be cast
+to or from a bool. The default initializer for bool3 is @code{default}.
+
+@item int
+@cindex @code{int}
+@cindex @code{intMin}
+@cindex @code{intMax}
+an integer type; if no initializer is given, the implicit value @code{0}
+is assumed. The minimum allowed value of an integer is @code{intMin} and the
+maximum value is @code{intMax}.
+
+@item real
+@cindex @code{real}
+@cindex @code{realMin}
+@cindex @code{realMax}
+@cindex @code{realEpsilon}
+@cindex @code{realDigits}
+@cindex @code{mask}
+@cindex @code{inf}
+@cindex @code{nan}
+@cindex @code{isnan}
+a real number; this should be set to the highest-precision native
+floating-point type on the architecture. The implicit initializer for
+reals is @code{0.0}. Real numbers have precision
+@code{realEpsilon}, with @code{realDigits} significant digits.
+The smallest positive real number is @code{realMin} and the largest
+positive real number is @code{realMax}.
+The variables @code{inf} and @code{nan}, along with the function
+@code{bool isnan(real x)} are useful when floating-point exceptions
+are masked with the @code{-mask} command-line option (the default in
+interactive mode).
+
+@item pair
+@cindex @code{pair}
+complex number, that is, an ordered pair of real components @code{(x,y)}.
+The real and imaginary parts of a pair @code{z} can read as @code{z.x}
+and @code{z.y}. We say that @code{x} and @code{y} are virtual members of
+the data element pair; they cannot be directly modified, however.
+The implicit initializer for pairs is @code{(0.0,0.0)}.
+
+There are a number of ways to take the complex conjugate of a pair:
+@example
+pair z=(3,4);
+z=(z.x,-z.y);
+z=z.x-I*z.y;
+z=conj(z);
+@end example
+
+Here @code{I} is the pair @code{(0,1)}.
+A number of built-in functions are defined for pairs:
+
+@table @code
+@item pair conj(pair z)
+@cindex @code{conj}
+returns the conjugate of @code{z};
+
+@item real length(pair z)
+@cindex @code{length}
+@cindex @code{abs}
+@cindex @code{abs2}
+returns the complex modulus @math{|@code{z}|} of its argument @code{z}.
+For example,
+@example
+pair z=(3,4);
+length(z);
+@end example
+returns the result 5. A synonym for @code{length(pair)} is @code{abs(pair)}.
+The function @code{abs2(pair z)} returns @math{|@code{z}|^2};
+
+@item real angle(pair z, bool warn=true)
+@cindex @code{angle}
+returns the angle of @code{z} in radians in the interval
+[-@code{pi},@code{pi}] or @code{0} if @code{warn} is @code{false} and
+@code{z=(0,0)} (rather than producing an error);
+
+@item real degrees(pair z, bool warn=true)
+@cindex @code{degrees}
+returns the angle of @code{z} in degrees in the interval [0,360)
+or @code{0} if @code{warn} is @code{false} and @code{z=(0,0)} (rather than
+producing an error);
+
+@item pair unit(pair z)
+@cindex @code{unit}
+returns a unit vector in the direction of the pair @code{z};
+
+@item pair expi(real angle)
+@cindex @code{expi}
+returns a unit vector in the direction @code{angle} measured in radians;
+
+@item pair dir(real degrees)
+@cindex @code{dir}
+returns a unit vector in the direction @code{degrees} measured in degrees;
+
+@item real xpart(pair z)
+@cindex @code{xpart}
+returns @code{z.x};
+
+@item real ypart(pair z)
+@cindex @code{ypart}
+returns @code{z.y};
+
+@item pair realmult(pair z, pair w)
+@cindex @code{realmult}
+returns the element-by-element product @code{(z.x*w.x,z.y*w.y)};
+
+@item real dot(explicit pair z, explicit pair w)
+@cindex @code{dot}
+returns the dot product @code{z.x*w.x+z.y*w.y};
+
+@item real cross(explicit pair z, explicit pair w)
+@cindex @code{cross}
+returns the 2D scalar product @code{z.x*w.y-z.y*w.x};
+
+@cindex @code{orient}
+@item real orient(pair a, pair b, pair c);
+returns a positive (negative) value if @code{a--b--c--cycle} is oriented
+counterclockwise (clockwise) or zero if all three points are colinear.
+Equivalently, a positive (negative) value is returned if
+@code{c} lies to the left (right) of the line through @code{a} and @code{b}
+or zero if @code{c} lies on this line.
+The value returned can be expressed in terms of the 2D scalar cross product
+as @code{cross(a-c,b-c)}, which is the determinant
+@verbatim
+|a.x a.y 1|
+|b.x b.y 1|
+|c.x c.y 1|
+@end verbatim
+
+@cindex @code{incircle}
+@item real incircle(pair a, pair b, pair c, pair d);
+returns a positive (negative) value if @code{d} lies inside (outside)
+the circle passing through the counterclockwise-oriented points @code{a,b,c}
+or zero if @code{d} lies on the this circle.
+The value returned is the determinant
+@verbatim
+|a.x a.y a.x^2+a.y^2 1|
+|b.x b.y b.x^2+b.y^2 1|
+|c.x c.y c.x^2+c.y^2 1|
+|d.x d.y d.x^2+d.y^2 1|
+@end verbatim
+
+@item pair minbound(pair z, pair w)
+@cindex @code{minbound}
+returns @code{(min(z.x,w.x),min(z.y,w.y))};
+
+@item pair maxbound(pair z, pair w)
+@cindex @code{maxbound}
+returns @code{(max(z.x,w.x),max(z.y,w.y))}.

+@cindex @code{slice}
+@item slice firstcut(path p, path knife);
+equivalent to @code{cut(p,knife,0);}
+@cindex @code{MetaPost cutbefore}
+Note that @code{firstcut.after} plays the role of the @code{MetaPost
+cutbefore} command.
+
+@cindex @code{lastcut}
+@item slice lastcut(path p, path knife);
+equivalent to @code{cut(p,knife,-1);}
+@cindex @code{MetaPost cutafter}
+Note that @code{lastcut.before} plays the role of the

+
+@cindex @code{buildcycle}
+@item path buildcycle(... path[] p);
+This returns the path surrounding a region bounded by a list of two or more
+consecutively intersecting paths, following the behaviour of the
+@code{MetaPost buildcycle} command.
+
+@cindex @code{min}
+@item pair min(path p);
+returns the pair (left,bottom) for the path bounding box of path @code{p}.

+returns the pair (right,top) for the path bounding box of path @code{p}.
+
+@cindex @code{windingnumber}
+@cindex @code{undefined}
+@item int windingnumber(path p, pair z);
+returns the winding number of the cyclic path @code{p} relative to the point
+@code{z}. The winding number is positive if the path encircles @code{z} in the
+counterclockwise direction. If @code{z} lies on @code{p} the constant
+@code{undefined} (defined to be the largest odd integer) is returned.
+
+@cindex @code{interior}
+@item bool interior(int windingnumber, pen fillrule)
+returns true if @code{windingnumber} corresponds to an interior point
+according to @code{fillrule}.
+

+@code{g} with pen @code{p}.
+
+@end table
+
+@item guide
+@cindex @code{guide}
+an unresolved cubic spline (list of cubic-spline nodes and control points).
+The implicit initializer for a guide is @code{nullpath}; this is useful
+for building up a guide within a loop.
+
+A guide is similar to a path except that the computation of the cubic spline is
+deferred until drawing time (when it is resolved into a path); this allows
+two guides with free endpoint conditions to be joined together smoothly.
+The solid curve in the following example is built up incrementally as
+a guide, but only resolved at drawing time; the dashed curve is
+incrementally resolved at each iteration, before the entire set of nodes
+(shown in red) is known:
+
+@verbatiminclude mexicanhat.asy
+@sp 1
+@center @image{./mexicanhat}
+
+We point out an efficiency distinction in the use of guides and paths:
+@verbatim
+guide g;
+for(int i=0; i < 10; ++i)
+ g=g--(i,i);
+path p=g;
+@end verbatim
+
+@noindent
+runs in linear time, whereas
+@verbatim
+path p;
+for(int i=0; i < 10; ++i)
+ p=p--(i,i);
+@end verbatim
+
+@noindent
+runs in quadratic time, as the entire path up to that point is copied at each
+step of the iteration.
+
+The following routines can be used to examine the individual elements of
+a guide without actually resolving the guide to a fixed path (except for
+internal cycles, which are resolved):
+
+@table @code
+
+@cindex @code{size}
+@item int size(guide g);
+Analogous to @code{size(path p)}.
+
+@cindex @code{length}
+@item int length(guide g);
+Analogous to @code{length(path p)}.
+
+@cindex @code{cyclic}
+@item bool cyclic(path p);
+Analogous to @code{cyclic(path p)}.
+
+@cindex @code{point}
+@item pair point(guide g, int t);
+Analogous to @code{point(path p, int t)}.
+
+@cindex @code{reverse}
+@item guide reverse(guide g);
+Analogous to @code{reverse(path p)}. If @code{g} is cyclic and
+also contains a secondary cycle, it is first solved to a
+path, then reversed. If @code{g} is not cyclic but contains an internal
+cycle, only the internal cycle is solved before reversal. If there are
+no internal cycles, the guide is reversed but not solved to a path.
+
+@cindex @code{dirSpecifier}
+@item pair[] dirSpecifier(guide g, int i);
+This returns a pair array of length 2 containing the outgoing (in
+element 0) and incoming (in element 1) direction specifiers (or
+@code{(0,0)} if none specified) for the segment of guide @code{g}
+between nodes @code{i} and @code{i+1}.
+
+@cindex @code{controlSpecifier}
+@item pair[] controlSpecifier(guide g, int i);
+If the segment of guide @code{g} between nodes @code{i} and @code{i+1}
+has explicit outgoing and incoming control points, they are returned as
+elements 0 and 1, respectively, of a two-element array. Otherwise, an
+empty array is returned.
+
+@cindex @code{tensionSpecifier}
+@item tensionSpecifier tensionSpecifier(guide g, int i);
+This returns the tension specifier for the segment of guide @code{g} between
+nodes @code{i} and @code{i+1}. The individual components of the
+@code{tensionSpecifier} type can be accessed as the virtual members
+@code{in}, @code{out}, and @code{atLeast}.
+
+@cindex @code{curlSpecifier}
+@item real[] curlSpecifier(guide g);
+This returns an array containing the initial curl specifier (in element 0)
+and final curl specifier (in element 1) for guide @code{g}.
+
+@end table
+
+As a technical detail we note that a direction specifier given to
+@code{nullpath} modifies the node on the other side: the guides
+@verbatim
+a..{up}nullpath..b;
+c..nullpath{up}..d;
+e..{up}nullpath{down}..f;
+@end verbatim
+are respectively equivalent to

+
+@cindex @code{pen}
+@cindex @code{currentpen}
+@cindex @code{MetaPost pickup}
+In @code{Asymptote}, pens provide a context for the four basic drawing
+commands (@pxref{Drawing commands}). They are used to specify the
+following drawing attributes: color, line type, line width, line cap,
+line join, fill rule, text alignment, font, font size, pattern,
+overwrite mode, and calligraphic transforms on the pen nib. The
+default pen used by the drawing routines is called
+@code{currentpen}. This provides the same functionality as the
+@code{MetaPost} command @code{pickup}.
+The implicit initializer for pens is @code{defaultpen}.
+
+@cindex @code{+}
+@cindex @code{*}
+Pens may be added together with the nonassociative binary
+operator @code{+}. This will add the colors of the two pens.
+All other non-default attributes of the rightmost pen will
+override those of the leftmost pen. Thus, one can obtain a yellow
+dashed pen by saying @code{dashed+red+green} or @code{red+green+dashed}
+or @code{red+dashed+green}. The binary operator @code{*}
+can be used to scale the color of a pen by a real number, until it
+saturates with one or more color components equal to 1.
+
+@itemize @bullet
+
+@item Colors are specified using one of the following colorspaces:
+@cindex color
+@table @code
+@item pen gray(real g);
+@cindex @code{gray}
+@cindex grayscale
+This produces a grayscale color, where the intensity @code{g} lies in the
+interval [0,1], with 0.0 denoting black and 1.0 denoting white.
+
+@item pen rgb(real r, real g, real b);
+@cindex @code{rgb}
+This produces an @acronym{RGB} color, where each of the red, green,
+and blue intensities @code{r}, @code{g}, @code{b}, lies in the interval [0,1].
+
+@item pen RGB(int r, int g, int b);
+@cindex @code{rgb}
+This produces an @acronym{RGB} color, where each of the red, green,
+and blue intensities @code{r}, @code{g}, @code{b}, lies in the
+interval [0,255].
+
+@item pen cmyk(real c, real m, real y, real k);
+@cindex @code{cmyk}
+This produces a @acronym{CMYK} color, where each of the cyan, magenta,
+yellow, and black intensities @code{c}, @code{m}, @code{y}, @code{k},
+lies in the interval [0,1].
+
+@item pen invisible;
+@cindex @code{invisible}
+This special pen writes in invisible ink, but adjusts the bounding
+box as if something had been drawn (like the @code{\phantom}
+command in @TeX{}). The function @code{bool invisible(pen)} can be used
+to test whether a pen is invisible.
+
+@end table
+
+@cindex @code{defaultpen}
+The default color is @code{black}; this may be changed with the routine
+@code{defaultpen(pen)}. The function @code{colorspace(pen p)} returns
+the colorspace of pen @code{p} as a string (@code{"gray"}, @code{"rgb"},
+@code{"cmyk"}, or @code{""}).
+
+@cindex @code{colors}
+The function @code{real[] colors(pen)} returns the color components of a pen.
+The functions @code{pen gray(pen)}, @code{pen rgb(pen)}, and
+@code{pen cmyk(pen)} return new pens obtained by converting their
+arguments to the respective color spaces.
+@cindex @code{colorless}
+The function @code{colorless(pen=currentpen)} returns a copy of its argument
+with the color attributes stripped (to avoid color mixing).
+
+A 6-character RGB hexadecimal string can be converted to a pen with
+the routine
+@cindex @code{rgb}
+@cindex @code{hexadecimal}
+@verbatim
+pen rgb(string s);
+@end verbatim
+@noindent
+A pen can be converted to a hexadecimal string with
+@cindex @code{hex}
+@item string hex(pen p);
+
+Various shades and mixtures of the grayscale primary colors
+@code{black} and @code{white}, @acronym{RGB} primary colors
+@code{red}, @code{green}, and @code{blue}, and
+@acronym{RGB} secondary colors @code{cyan}, @code{magenta}, and @code{yellow}
+are defined as named colors, along with the @acronym{CMYK} primary
+colors @code{Cyan}, @code{Magenta}, @code{Yellow}, and @code{Black}, in
+the module @code{plain}:
+@sp 1
+@center @image{./colors}
+
+The standard 140 @acronym{RGB} @code{X11} colors can be imported with
+the command
+@verbatim
+import x11colors;
+@end verbatim
+and the standard 68 @acronym{CMYK} @TeX{} colors can be imported with
+the command
+@verbatim
+import texcolors;
+@end verbatim
+Note that there is some overlap between these two standards
+and the definitions of some colors (e.g.@ @code{Green}) actually disagree.
+
+@code{Asymptote} also comes with a @code{asycolors.sty} @code{LaTeX} package
+that defines to @code{LaTeX} @acronym{CMYK} versions of
+@code{Asymptote}'s predefined colors, so that they can be used
+directly within @code{LaTeX} strings. Normally, such colors are
+passed to @code{LaTeX} via a pen argument; however, to change the
+color of only a portion of a string, say for a slide presentation,
+(@pxref{slide}) it may be desirable to specify the color directly to
+@code{LaTeX}. This file can be passed to @code{LaTeX} with the
+@code{Asymptote} command
+@verbatim
+usepackage("asycolors");
+@end verbatim
+
+The structure @code{hsv} defined in @code{plain_pens.asy} may be used
+to convert between @acronym{HSV} and @acronym{RGB} spaces, where
+the hue @code{h} is an angle in @math{[0,360)} and the saturation
+@code{s} and value @code{v} lie in @code{[0,1]}:

+@cindex @code{dotted}
+@cindex @code{longdashed}
+@cindex @code{dashdotted}
+@cindex @code{longdashdotted}
+where @code{a} is an array of real array numbers.
+The optional parameter @code{offset} specifies where in the pattern
+to begin. The first number specifies how far (if @code{scale} is
+@code{true}, in units of the pen line width; otherwise in
+@code{PostScript} units) to draw with the pen on, the second number
+specifies how far to draw with the pen off, and so on. If
+@code{adjust} is @code{true}, these spacings are automatically
+adjusted by @code{Asymptote} to fit the arclength of the path. Here
+are the predefined line types:
+@verbatim

+@cindex @code{linetype}
+@cindex @code{offset}
+@cindex @code{scale}
+@cindex @code{adjust}
+The line type of a pen can be determined with the functions
+@code{real[] linetype(pen p=currentpen)},
+@code{real offset(pen p)}, @code{bool scale(pen p)}, and
+@code{bool adjust(pen p)}.
+
+@cindex @code{linewidth}

+@item The pen line width is specified in @code{PostScript} units with
+@code{pen linewidth(real)}. The default line width is 0.5 bp; this value
+may be changed with @code{defaultpen(pen)}. The line width of a pen
+is returned by @code{real linewidth(pen p=currentpen)}.
+For convenience, in the module @code{plain_pens} we define

+pen operator +(pen p, real w) {return p+linewidth(w);}
+pen operator +(real w, pen p) {return linewidth(w)+p;}

+@verbatim
+pen squarecap=linecap(0);
+pen roundcap=linecap(1);
+pen extendcap=linecap(2);
+@end verbatim
+
+@noindent
+The default line cap, @code{roundcap}, may be changed with

+pen roundjoin=linejoin(1);
+pen beveljoin=linejoin(2);
+@end verbatim
+
+@noindent
+The default join style, @code{roundjoin}, may be changed with

+@code{int linejoin(pen p=currentpen)}.
+
+@cindex @code{miterlimit}
+@item A pen with a specific @code{PostScript} miter limit is returned by
+calling @code{miterlimit(real)}.
+The default miterlimit, @code{10.0}, may be changed with

+@verbatim
+pen zerowinding=fillrule(0);
+pen evenodd=fillrule(1);
+@end verbatim
+
+@noindent
+The fill rule, which identifies the algorithm used to determine the
+insideness of a path or array of paths, only affects the @code{clip},
+@code{fill}, and @code{inside} functions. For the @code{zerowinding}
+fill rule, a point @code{z} is outside the region bounded by a path if
+the number of upward intersections of the path with the horizontal
+line @code{z--z+infinity} minus the number of downward intersections
+is zero. For the @code{evenodd} fill rule, @code{z} is considered to
+be outside the region if the total number of such intersections is even.
+The default fill rule, @code{zerowinding}, may be changed with
+@code{defaultpen(pen)}. The fill rule of a pen is returned by
+@code{int fillrule(pen p=currentpen)}.
+
+@cindex @code{nobasealign}

+calling @code{basealign} with an integer argument:
+@verbatim
+pen nobasealign=basealign(0);
+pen basealign=basealign(1);
+@end verbatim
+
+@noindent
+The default setting, @code{nobasealign},which may be changed with
+@code{defaultpen(pen)}, causes the label alignment routines to use the
+full label bounding box for alignment. In contrast, @code{basealign}
+requests that the @TeX{} baseline be respected.
+The base align setting of a pen is returned by
+@code{int basealign(pen p=currentpen)}.
+
+@cindex @code{fontsize}
+@cindex @code{lineskip}
+@cindex @code{defaultpen}

+the function @code{pen fontsize(real size, real lineskip=1.2*size)}.
+The default font size, 12pt, may be changed with @code{defaultpen(pen)}.
+Nonstandard font sizes may require inserting
+@verbatim
+import fontsize;
+@end verbatim
+at the beginning of the file (this requires the @code{type1cm} package
+available from
+@quotation
+@url{http://mirror.ctan.org/macros/latex/contrib/type1cm/}
+@end quotation
+and included in recent @code{LaTeX} distributions). The font size and line
+skip of a pen can be examined with the routines
+@code{real fontsize(pen p=currentpen)} and
+@code{real lineskip(pen p=currentpen)}, respectively.
+
+@cindex font
+@cindex @LaTeX{} NFSS fonts
+@cindex @code{font}
+@item A pen using a specific @LaTeX{} NFSS font is returned
+by calling the function @code{pen font(string encoding, string family,
+string series, string shape)}. The default setting,
+@code{font("OT1","cmr","m","n")}, corresponds to 12pt Computer Modern Roman;
+this may be changed with @code{defaultpen(pen)}.
+The font setting of a pen is returned by
+@code{string font(pen p=currentpen)}.
+
+@cindex @TeX{} fonts
+Alternatively, one may select a fixed-size @TeX{} font (on which
+@code{fontsize} has no effect) like @code{"cmr12"} (12pt Computer Modern
+Roman) or @code{"pcrr"} (Courier) using the function @code{pen font(string
+name)}. An optional size argument can also be given to scale the font
+to the requested size: @code{pen font(string name, real size)}.
+
+@cindex @code{fontcommand}
+A nonstandard font command can be generated with
+@code{pen fontcommand(string)}.
+
+@cindex @code{PostScript} fonts

+@anchor{transparency}
+@cindex transparency
+@cindex @code{opacity}
+@item The transparency of a pen can be changed with the command:
+@verbatim
+pen opacity(real opacity=1, string blend="Compatible");
+@end verbatim
+The opacity can be varied from @code{0} (fully transparent) to the default
+value of @code{1} (opaque), and @code{blend} specifies one of the
+following foreground--background blending operations:
+@verbatim
+"Compatible","Normal","Multiply","Screen","Overlay","SoftLight",
+"HardLight","ColorDodge","ColorBurn","Darken","Lighten","Difference",
+"Exclusion","Hue","Saturation","Color","Luminosity",
+@end verbatim
+as described in
+@url{https://www.adobe.com/content/dam/acom/en/devnet/pdf/pdfs/PDF32000_2008.pdf}.
+Since @code{PostScript} does not support transparency, this feature is
+only effective with the @code{-f pdf} output format option; other
+formats can be produced from the resulting @acronym{PDF} file with the
+@code{ImageMagick} @code{convert} program.
+Labels are always drawn with an @code{opacity} of 1.
+A simple example of transparent filling is provided in the example file
+@code{@uref{https://asymptote.sourceforge.io/gallery/transparency.svg,,transparency}@uref{https://asymptote.sourceforge.io/gallery/transparency.asy,,.asy}}.
+
+@cindex patterns
+@cindex tilings
+@item @code{PostScript} commands within a @code{picture} may be used
+to create a tiling pattern, identified by the string @code{name}, for
+@code{fill} and @code{draw} operations by adding it to the
+global @code{PostScript} frame @code{currentpatterns},
+with optional left-bottom margin @code{lb} and right-top margin @code{rt}.
+@verbatim
+import patterns;
+void add(string name, picture pic, pair lb=0, pair rt=0);
+@end verbatim
+
+To @code{fill} or @code{draw} using pattern @code{name}, use
+the pen @code{pattern("name")}. For example, rectangular tilings
+can be constructed using the routines
+@code{picture tile(real Hx=5mm, real Hy=0, pen p=currentpen,
+filltype filltype=NoFill)},
+@code{picture checker(real Hx=5mm, real Hy=0, pen p=currentpen)}, and

+@cindex checker
+@cindex brick
+@verbatiminclude tile.asy
+@sp 1

+@code{picture crosshatch(real H=5mm, pen p=currentpen)}:
+@verbatiminclude hatch.asy
+@sp 1
+@center @image{./hatch}
+

+This is equivalent to the @code{PostScript} transformation
+@code{[t.xx t.yx t.xy t.yy t.x t.y]}.
+
+Transforms can be applied to pairs, guides, paths, pens, strings,
+transforms, frames, and pictures by multiplication (via the binary operator
+@code{*}) on the left (@pxref{circle} for an example).

+Frames are canvases for drawing in @code{PostScript} coordinates. While working
+with frames directly is occasionally necessary for constructing deferred

+The implicit initializer for frames is @code{newframe}. The function
+@code{bool empty(frame f)} returns @code{true} only if the frame @code{f}
+is empty. A frame may be erased with the @code{erase(frame)} routine.
+The functions @code{pair min(frame)} and @code{pair max(frame)}
+return the (left,bottom) and (right,top) coordinates of the frame
+bounding box, respectively. The contents of frame @code{src} may be
+appended to frame @code{dest} with the command
+@verbatim
+void add(frame dest, frame src);
+@end verbatim
+or prepended with
+@verbatim
+void prepend(frame dest, frame src);

+@item picture
+@cindex @code{picture}
+Pictures are high-level structures (@pxref{Structures}) defined in
+the module @code{plain} that provide canvases for drawing in user coordinates.
+The default picture is called @code{currentpicture}. A new picture
+can be created like this:
+@verbatim
+picture pic;
+@end verbatim
+@noindent
+Anonymous pictures can be made by the expression @code{new picture}.
+
+The @code{size} routine specifies the dimensions of the desired picture:
+
+@anchor{size}
+@cindex @code{size}
+@verbatim
+void size(picture pic=currentpicture, real x, real y=x,
+ bool keepAspect=Aspect);
+@end verbatim
+
+If the @code{x} and @code{y} sizes are both 0, user coordinates will be
+interpreted as @code{PostScript} coordinates. In this case, the transform
+mapping @code{pic} to the final output frame is @code{identity()}.
+
+If exactly one of @code{x} or @code{y} is 0, no size restriction
+is imposed in that direction; it will be scaled the same as the other
+direction.
+
+@cindex @code{keepAspect}
+@cindex @code{Aspect}
+If @code{keepAspect} is set to @code{Aspect} or @code{true},
+the picture will be scaled with its aspect ratio preserved such that
+the final width is no more than @code{x} and the final height is
+no more than @code{y}.
+
+@cindex @code{keepAspect}
+@cindex @code{IgnoreAspect}
+If @code{keepAspect} is set to @code{IgnoreAspect} or @code{false},
+the picture will be scaled in both directions so that the final width
+is @code{x} and the height is @code{y}.
+
+To make the user coordinates of picture @code{pic}
+represent multiples of @code{x} units in the @math{x} direction and
+@code{y} units in the @math{y} direction, use
+@anchor{unitsize}
+@cindex @code{unitsize}
+@verbatim
+void unitsize(picture pic=currentpicture, real x, real y=x);
+@end verbatim
+When nonzero, these @code{x} and @code{y} values override the
+corresponding size parameters of picture @code{pic}.
+
+The routine
+@cindex @code{size}
+@verbatim
+void size(picture pic=currentpicture, real xsize, real ysize,
+ pair min, pair max);
+@end verbatim
+forces the final picture scaling to map the user coordinates
+@code{box(min,max)} to a region of width @code{xsize} and height @code{ysize}
+(when these parameters are nonzero).
+
+Alternatively, calling the routine
+@cindex @code{fixedscaling}
+@verbatim
+transform fixedscaling(picture pic=currentpicture, pair min,
+ pair max, pen p=nullpen, bool warn=false);
+@end verbatim
+will cause picture @code{pic} to use a fixed scaling to map user
+coordinates in @code{box(min,max)} to the (already specified) picture size,
+taking account of the width of pen @code{p}. A warning will be issued if
+the final picture exceeds the specified size.
+
+A picture @code{pic} can be fit to a frame and output to a file
+@code{prefix}.@code{format} using image format @code{format}
+by calling the @code{shipout} function:
+@anchor{shipout}
+@cindex @code{shipout}
+@cindex @code{outprefix}
+@verbatim
+void shipout(string prefix=defaultfilename, picture pic=currentpicture,
+ orientation orientation=orientation,
+ string format="", bool wait=false, bool view=true,
+ string options="", string script="",
+ light light=currentlight, projection P=currentprojection)
+@end verbatim
+@noindent
+The default output format, @code{PostScript}, may be changed
+with the @code{-f} or @code{-tex} command-line options.
+The @code{options}, @code{script}, and @code{projection} parameters
+are only relevant for 3D pictures. If @code{defaultfilename} is an
+empty string, the prefix @code{outprefix()} will be used.
+
+A @code{shipout()} command is added implicitly at file exit if no
+previous @code{shipout} commands have been executed.
+@cindex @code{orientation}
+@cindex @code{Portrait}
+@cindex @code{Landscape}
+@cindex @code{UpsideDown}
+The default page orientation is @code{Portrait}; this may be modified
+by changing the variable @code{orientation}. To output in landscape
+mode, simply set the variable @code{orientation=Landscape} or issue
+the command
+@verbatim
+shipout(Landscape);
+@end verbatim
+
+@cindex @code{Seascape}
+To rotate the page by @math{-90} degrees, use the orientation @code{Seascape}.
+@cindex @code{UpsideDown}
+The orientation @code{UpsideDown} rotates the page by 180 degrees.
+
+@cindex subpictures
+@cindex @code{fit}
+A picture @code{pic} can be explicitly fit to a frame by calling
+@verbatim
+frame pic.fit(real xsize=pic.xsize, real ysize=pic.ysize,
+ bool keepAspect=pic.keepAspect);
+@end verbatim
+The default size and aspect ratio settings are those given to the
+@code{size} command (which default to @code{0}, @code{0}, and
+@code{true}, respectively).
+@cindex @code{calculateTransform}
+The transformation that would currently be used to fit a picture
+@code{pic} to a frame is returned by the member function
+@code{pic.calculateTransform()}.
+
+In certain cases (e.g.@ 2D graphs) where only an approximate size
+estimate for @code{pic} is available, the picture fitting routine
+@verbatim
+frame pic.scale(real xsize=this.xsize, real ysize=this.ysize,
+ bool keepAspect=this.keepAspect);
+@end verbatim
+(which scales the resulting frame, including labels and fixed-size

+
+@cindex @code{box}
+To draw a bounding box with margins around a picture, fit the

+@verbatim
+frame bbox(picture pic=currentpicture, real xmargin=0,
+ real ymargin=xmargin, pen p=currentpen,
+ filltype filltype=NoFill);
+@end verbatim
+@anchor{filltype}

+otherwise fill with pen @code{fillpen}.
+If @code{drawpen} is @code{nullpen}, draw the boundary with @code{fillpen};

+@cindex @code{Fill}
+@item Fill
+Fill the interior.
+
+@cindex @code{nullpen}
+@item Fill(real xmargin=0, real ymargin=xmargin, pen p=nullpen)
+If @code{p} is @code{nullpen}, fill with the drawing pen;

+
+@cindex @code{NoFill}
+@item NoFill
+Do not fill.
+
+@item Draw
+Draw only the boundary.
+
+@cindex @code{Draw}
+@item Draw(real xmargin=0, real ymargin=xmargin, pen p=nullpen)
+If @code{p} is @code{nullpen}, draw the boundary with the drawing pen;

+@code{xmargin} and @code{ymargin} can be specified.
+
+@cindex @code{UnFill}
+@item UnFill
+Clip the region.
+
+@cindex @code{UnFill}
+@item UnFill(real xmargin=0, real ymargin=xmargin)
+Clip the region and surrounding margins @code{xmargin} and @code{ymargin}.
+
+@cindex @code{RadialShade}
+@item RadialShade(pen penc, pen penr)
+Fill varying radially from @code{penc} at the center of the bounding
+box to @code{penr} at the edge.
+
+@cindex @code{RadialShadeDraw}
+@item RadialShadeDraw(real xmargin=0, real ymargin=xmargin, pen penc,
+ @code{pen penr, pen drawpen=nullpen)}
+Fill with RadialShade and draw the boundary.
+
+@end table
+
+@cindex bounding box
+@cindex background color
+For example, to draw a bounding box around a picture with a 0.25 cm
+margin and output the resulting frame, use the command:
+@verbatim
+shipout(bbox(0.25cm));
+@end verbatim
+A @code{picture} may be fit to a frame with the background color
+pen @code{p}, using the function @code{bbox(p,Fill)}.
+
+@cindex @code{pad}
+To pad a picture to a precise size in both directions, fit the picture
+to a frame using the function
+@verbatim
+frame pad(picture pic=currentpicture, real xsize=pic.xsize,
+ real ysize=pic.ysize, filltype filltype=NoFill);
+@end verbatim
+
+The functions
+@verbatim
+pair min(picture pic, user=false);
+pair max(picture pic, user=false);
+pair size(picture pic, user=false);
+@end verbatim
+calculate the bounds that picture @code{pic} would
+have if it were currently fit to a frame using its default size specification.
+If @code{user} is @code{false} the returned value is in
+@code{PostScript} coordinates, otherwise it is in user coordinates.
+
+The function
+@verbatim
+pair point(picture pic=currentpicture, pair dir, bool user=true);
+@end verbatim
+is a convenient way of determining the point on the bounding box of
+@code{pic} in the direction @code{dir} relative to its center, ignoring
+the contributions from fixed-size objects (such as labels and arrowheads).
+If @code{user} is @code{true} the returned value is in user coordinates,
+otherwise it is in @code{PostScript} coordinates.
+
+The function
+@verbatim
+pair truepoint(picture pic=currentpicture, pair dir, bool user=true);
+@end verbatim
+is identical to @code{point}, except that it also accounts for
+fixed-size objects, using the scaling transform that picture @code{pic}
+would have if currently fit to a frame using its default size
+specification. If @code{user} is @code{true} the returned value is in
+user coordinates, otherwise it is in @code{PostScript} coordinates.
+
+@anchor{add}
+Sometimes it is useful to draw objects on separate pictures and add one
+picture to another using the @code{add} function:
+@cindex @code{add}
+@verbatim
+void add(picture src, bool group=true,
+ filltype filltype=NoFill, bool above=true);
+void add(picture dest, picture src, bool group=true,
+ filltype filltype=NoFill, bool above=true);
+@end verbatim
+@noindent
+The first example adds @code{src} to @code{currentpicture}; the second
+one adds @code{src} to @code{dest}.
+The @code{group} option specifies whether or not the graphical user
+interface should treat all of the elements of @code{src}
+as a single entity (@pxref{GUI}), @code{filltype} requests optional
+background filling or clipping, and @code{above} specifies
+whether to add @code{src} above or below existing objects.
+
+There are also routines to add a picture or frame @code{src} specified
+in postscript coordinates to another picture @code{dest} (or
+@code{currentpicture}) about the user coordinate
+@code{position}:
+@anchor{add about}
+@cindex @code{add}
+@cindex picture alignment
+@verbatim
+void add(picture src, pair position, bool group=true,
+ filltype filltype=NoFill, bool above=true);
+void add(picture dest, picture src, pair position,
+ bool group=true, filltype filltype=NoFill, bool above=true);
+void add(picture dest=currentpicture, frame src, pair position=0,
+ bool group=true, filltype filltype=NoFill, bool above=true);
+void add(picture dest=currentpicture, frame src, pair position,
+ pair align, bool group=true, filltype filltype=NoFill,
+ bool above=true);
+@end verbatim
+
+The optional @code{align} argument in the last form specifies a
+direction to use for aligning the frame, in a manner analogous to the
+@code{align} argument of @code{label} (@pxref{label}). However, one key
+difference is that when @code{align} is not specified, labels are
+centered, whereas frames and pictures are aligned so that their origin is
+at @code{position}. Illustrations of frame alignment can be found in
+the examples @ref{errorbars} and @ref{image}. If you want to align three
+or more subpictures, group them two at a time:
+
+@verbatiminclude subpictures.asy
+@sp 1
+@center @image{./subpictures}
+
+Alternatively, one can use @code{attach} to automatically increase the
+size of picture @code{dest} to accommodate adding a frame @code{src}
+about the user coordinate @code{position}:
+@cindex @code{attach}
+@verbatim
+void attach(picture dest=currentpicture, frame src,
+ pair position=0, bool group=true,
+ filltype filltype=NoFill, bool above=true);
+void attach(picture dest=currentpicture, frame src,
+ pair position, pair align, bool group=true,
+ filltype filltype=NoFill, bool above=true);
+@end verbatim
+
+@cindex @code{erase}
+To erase the contents of a picture (but not the size specification), use
+the function
+@verbatim
+void erase(picture pic=currentpicture);
+@end verbatim
+

+
+@cindex verbatim
+@cindex @code{postscript}

+@verbatim

+void postscript(picture pic=currentpicture, string s, pair min,
+ pair max)
+@end verbatim
+Here @code{min} and @code{max} can be used to specify explicit bounds
+associated with the resulting @code{PostScript} code.

+@end verbatim
+Here @code{min} and @code{max} can be used to specify explicit bounds

+@node Variable initializers, Structures, Files, Programming
+@section Variable initializers
+@cindex variable initializers
+@cindex @code{operator init}
+@cindex initializers
+
+A variable can be assigned a value when it is declared, as in
+@code{int x=3;} where the variable @code{x} is assigned the value @code{3}.
+As well as literal constants such as @code{3}, arbitary expressions can be used
+as initializers, as in @code{real x=2*sin(pi/2);}.
+
+A variable is not added to the namespace until after the initializer is
+evaluated, so for example, in
+@verbatim
+int x=2;
+int x=5*x;
+@end verbatim
+@noindent
+the @code{x} in the initializer on the second line refers to the variable
+@code{x} declared on the first line. The second line, then, declares a variable
+@code{x} shadowing the original @code{x} and initializes it to the value
+@code{10}.
+
+Variables of most types can be declared without an explicit initializer and they
+will be initialized by the default initializer of that type:
+
+@itemize
+@item Variables of the numeric types @code{int}, @code{real}, and @code{pair}
+are all initialized to zero; variables of type @code{triple} are
+initialized to @code{O=(0,0,0)}.
+@item @code{boolean} variables are initialized to @code{false}.
+@item @code{string} variables are initialized to the empty string.
+@item @code{transform} variables are initialized to the identity transformation.
+@item @code{path} and @code{guide} variables are initialized to
+@code{nullpath}.
+@item @code{pen} variables are initialized to the default pen.
+@item @code{frame} and @code{picture} variables are initialized to empty
+frames and pictures, respectively.
+@item @code{file} variables are initialized to @code{null}.
+@end itemize
+
+The default initializers for user-defined array, structure, and function types
+are explained in their respective sections. Some types, such as
+@code{code}, do not have default initializers. When a variable of such
+a type is introduced, the user must initialize it by explicitly giving
+it a value.
+
+The default initializer for any type @code{T} can be redeclared by defining the
+function @code{T operator init()}. For instance, @code{int} variables are
+usually initialized to zero, but in
+@verbatim
+int operator init() {
+ return 3;
+}
+int y;
+@end verbatim
+
+@noindent
+the variable @code{y} is initialized to @code{3}. This example was given for
+illustrative purposes; redeclaring the initializers of built-in types is not
+recommended. Typically, @code{operator init} is used to define sensible
+defaults for user-defined types.
+
+@cindex @code{var}
+The special type @code{var} may be used to infer the type of a variable from
+its initializer. If the initializer is an expression of a unique type, then
+the variable will be defined with that type. For instance,
+@verbatim
+var x=5;
+var y=4.3;
+var reddash=red+dashed;
+@end verbatim
+@noindent
+is equivalent to
+@verbatim
+int x=5;
+real y=4.3;
+pen reddash=red+dashed;
+@end verbatim
+
+@code{var} may also be used with the extended @code{for} loop syntax.
+
+@verbatim
+int[] a = {1,2,3};
+for (var x : a)
+ write(x);
+@end verbatim
+
+@node Structures, Operators, Variable initializers, Programming
+@section Structures
+@cindex @code{struct}
+@cindex structures
+@cindex @code{public}
+@cindex @code{restricted}
+@cindex @code{private}
+@cindex @code{this}
+@cindex @code{new}
+@cindex @code{null}
+
+Users may also define their own data types as structures, along with
+user-defined operators, much as in C++. By default, structure members
+are @code{public} (may be read and modified anywhere in the code), but may be
+optionally declared @code{restricted} (readable anywhere but writeable
+only inside the structure where they are defined) or @code{private}
+(readable and writable only inside the structure). In a structure definition,
+the keyword @code{this} can be used as an expression to refer to the enclosing
+structure. Any code at the
+top-level scope within the structure is executed on initialization.
+
+Variables hold references to structures. That is, in the example:
+@verbatim
+struct T {
+ int x;
+}
+
+T foo;
+T bar=foo;
+bar.x=5;
+@end verbatim
+
+The variable @code{foo} holds a reference to an instance of the structure
+@code{T}. When @code{bar} is assigned the value of @code{foo}, it too
+now holds a reference to the same instance as @code{foo} does. The assignment
+@code{bar.x=5} changes the value of the field @code{x} in that instance, so
+that @code{foo.x} will also be equal to @code{5}.
+
+The expression @code{new T} creates a new instance of the structure @code{T} and
+returns a reference to that instance. In creating the new instance, any code in
+the body of the record definition is executed. For example:
+@verbatim
+int Tcount=0;
+struct T {
+ int x;
+ ++Tcount;
+}
+
+T foo=new T;
+T foo;
+@end verbatim
+@noindent
+Here, @code{new T} produces a new instance of the class, which
+causes @code{Tcount} to be incremented, tracking the
+number of instances produced. The declarations @code{T foo=new T} and
+@code{T foo} are equivalent: the second form implicitly creates a new
+instance of @code{T}.
+That is, after the definition of a structure @code{T}, a variable of
+type @code{T} is initialized to a new instance (@code{new T}) by
+default. During the definition of the structure, however, variables
+of type @code{T} are initialized to @code{null} by default. This
+special behaviour is to avoid infinite recursion of creating new
+instances in code such as
+@verbatim
+struct tree {
+ int value;
+ tree left;
+ tree right;
+}
+@end verbatim
+
+The expression @code{null} can be cast to any structure type to yield a null
+reference, a reference that does not actually refer to any instance of the
+structure. Trying to use a field of a null reference will cause an error.
+
+@cindex alias
+@cindex @code{==}
+@cindex @code{!=}
+The function @code{bool alias(T,T)} checks to see if two structure references
+refer to the same instance of the structure (or both to @code{null}).
+In example at the beginning of this section, @code{alias(foo,bar)}
+would return true, but @code{alias(foo,new T)} would return false, as @code{new
+T} creates a new instance of the structure @code{T}. The boolean operators
+@code{==} and @code{!=} are by default equivalent to @code{alias} and
+@code{!alias} respectively, but may be overwritten for a particular type
+(for example, to do a deep comparison).
+
+Here is a simple example that illustrates the use of structures:
+@verbatim
+struct S {
+ real a=1;
+ real f(real a) {return a+this.a;}
+}
+
+S s; // Initializes s with new S;
+
+write(s.f(2)); // Outputs 3
+
+S operator + (S s1, S s2)
+{
+ S result;
+ result.a=s1.a+s2.a;
+ return result;
+}
+
+write((s+s).f(0)); // Outputs 2
+
+@end verbatim
+
+@cindex constructors
+It is often convenient to have functions that construct new instances of a
+structure. Say we have a @code{Person} structure:
+@verbatim
+struct Person {
+ string firstname;
+ string lastname;
+}
+
+Person joe;
+joe.firstname="Joe";
+joe.lastname="Jones";
+@end verbatim
+@noindent
+Creating a new Person is a chore; it takes three lines to create a new instance
+and to initialize its fields (that's still considerably less effort than
+creating a new person in real life, though).
+
+We can reduce the work by defining a constructor function
+@code{Person(string,string)}:
+@verbatim
+struct Person {
+ string firstname;
+ string lastname;
+
+ static Person Person(string firstname, string lastname) {
+ Person p=new Person;
+ p.firstname=firstname;
+ p.lastname=lastname;
+ return p;
+ }
+}
+
+Person joe=Person.Person("Joe", "Jones");
+@end verbatim
+
+While it is now easier than before to create a new instance, we still
+have to refer to the constructor by the qualified name
+@code{Person.Person}. If we add the line
+@verbatim
+from Person unravel Person;
+@end verbatim
+@noindent
+immediately after the structure definition, then the constructor can be used
+without qualification: @code{Person joe=Person("Joe", "Jones");}.
+
+The constructor is now easy to use, but it is quite a hassle to define. If you
+write a lot of constructors, you will find that you are repeating a lot of code
+in each of them. Fortunately, your friendly neighbourhood Asymptote
+developers have devised a way to automate much of the process.
+
+@cindex @code{operator init}
+If, in the body of a structure, Asymptote encounters the definition of
+a function of the form @code{void operator init(@var{args})}, it implicitly
+defines a constructor function of the arguments @code{@var{args}} that
+uses the @code{void operator init} function to initialize a
+new instance of the structure.
+That is, it essentially defines the following constructor (assuming the
+structure is called @code{Foo}):
+
+@example
+static Foo Foo(@var{args}) @{
+ Foo instance=new Foo;
+ instance.operator init(@var{args});
+ return instance;
+@}
+@end example
+
+This constructor is also implicitly copied to the enclosing scope after the end
+of the structure definition, so that it can used subsequently without qualifying
+it by the structure name. Our @code{Person} example can thus be implemented as:
+@verbatim
+struct Person {
+ string firstname;
+ string lastname;
+
+ void operator init(string firstname, string lastname) {
+ this.firstname=firstname;
+ this.lastname=lastname;
+ }
+}
+
+Person joe=Person("Joe", "Jones");
+@end verbatim
+
+The use of @code{operator init} to implicitly define constructors should not be
+confused with its use to define default values for variables
+(@pxref{Variable initializers}). Indeed, in the
+first case, the return type of the @code{operator init} must be @code{void}
+while in the second, it must be the (non-@code{void}) type of the variable.
+
+@cindex @code{cputime}
+The function @code{cputime()}
+returns a structure @code{cputime} with cumulative @acronym{CPU} times
+broken down into the fields @code{parent.user}, @code{parent.system},
+@code{child.user}, and @code{child.system}, along with the cumulative
+wall clock time in @code{parent.clock}, all measured in seconds.
+For convenience, the incremental fields @code{change.user},
+@code{change.system}, and @code{change.clock} indicate the change in
+the corresponding fields since the last call to @code{cputime()}. The
+function
+@verbatim
+void write(file file=stdout, string s="", cputime c,
+ string format=cputimeformat, suffix suffix=none);
+@end verbatim
+@noindent
+displays the incremental user cputime followed by ``u'',
+the incremental system cputime followed by ``s'',
+the total user cputime followed by ``U'', and
+the total system cputime followed by ``S''.
+
+@cindex inheritance
+@cindex virtual functions
+Much like in C++, casting (@pxref{Casts}) provides for an elegant
+implementation of structure inheritance, including virtual functions:
+@verbatim
+struct parent {
+ real x;
+ void operator init(int x) {this.x=x;}
+ void virtual(int) {write(0);}
+ void f() {virtual(1);}
+}
+
+void write(parent p) {write(p.x);}
+
+struct child {
+ parent parent;
+ real y=3;
+ void operator init(int x) {parent.operator init(x);}
+ void virtual(int x) {write(x);}
+ parent.virtual=virtual;
+ void f()=parent.f;
+}
+
+parent operator cast(child child) {return child.parent;}
+
+parent p=parent(1);
+child c=child(2);
+
+write(c); // Outputs 2;
+
+p.f(); // Outputs 0;
+c.f(); // Outputs 1;
+
+write(c.parent.x); // Outputs 2;
+write(c.y); // Outputs 3;
+@end verbatim

+
+@code{Asymptote} functions are treated as variables with a signature
+(non-function variables have null signatures). Variables with the
+same name are allowed, so long as they have distinct signatures.
+
+Function arguments are passed by value. To pass an argument by
+reference, simply enclose it in a structure (@pxref{Structures}).
+
+Here are some significant features of @code{Asymptote} functions:
+
+@enumerate
+@item Variables with signatures (functions) and without signatures
+(nonfunction variables) are distinct:
+@verbatim
+int x, x();
+x=5;
+x=new int() {return 17;};
+x=x(); // calls x() and puts the result, 17, in the scalar x
+@end verbatim
+
+@item Traditional function definitions are allowed:
+@verbatim
+int sqr(int x)
+{
+ return x*x;
+}
+sqr=null; // but the function is still just a variable.
+@end verbatim
+
+@item Casting can be used to resolve ambiguities:
+@verbatim
+int a, a(), b, b(); // Valid: creates four variables.
+a=b; // Invalid: assignment is ambiguous.
+a=(int) b; // Valid: resolves ambiguity.
+(int) (a=b); // Valid: resolves ambiguity.
+(int) a=b; // Invalid: cast expressions cannot be L-values.
+
+int c();
+c=a; // Valid: only one possible assignment.
+@end verbatim
+
+@item Anonymous (so-called "high-order") functions are also allowed:
+@cindex @code{typedef}
+@verbatim
+typedef int intop(int);
+intop adder(int m)
+{
+ return new int(int n) {return m+n;};
+}
+intop addby7=adder(7);
+write(addby7(1)); // Writes 8.
+@end verbatim
+
+@item
+@cindex overloading functions
+One may redefine a function @code{f}, even for calls to @code{f} in previously
+declared functions, by assigning another (anonymous or named)
+function to it. However, if @code{f} is overloaded by a
+new function definition, previous calls will still access the original
+version of @code{f}, as illustrated in this example:
+@verbatim
+void f() {
+ write("hi");
+}
+
+void g() {
+ f();
+}
+
+g(); // writes "hi"
+
+f=new void() {write("bye");};
+
+g(); // writes "bye"
+
+void f() {write("overloaded");};
+
+f(); // writes "overloaded"
+g(); // writes "bye"
+@end verbatim
+
+@cindex function declarations
+@item Anonymous functions can be used to redefine a function variable
+that has been declared (and implicitly initialized to the null function)
+but not yet explicitly defined:
+@verbatim
+void f(bool b);
+
+void g(bool b) {
+ if(b) f(b);
+ else write(b);
+}
+
+f=new void(bool b) {
+ write(b);
+ g(false);
+};
+
+g(true); // Writes true, then writes false.
+@end verbatim
+
+@end enumerate
+
+@code{Asymptote} is the only language we know of that treats functions
+as variables, but allows overloading by distinguishing variables
+based on their signatures.

+@cindex stack overflow
+Functions are allowed to call themselves recursively. As in C++, infinite
+nested recursion will generate a stack overflow (reported as a
+segmentation fault, unless a fully working version of the @acronym{GNU}
+library @code{libsigsegv} (e.g.@ 2.4 or later) is installed at
+configuration time).
+
+@node Default arguments, Named arguments, Functions, Functions
+@subsection Default arguments
+@cindex default arguments
+@cindex arguments
+
+@code{Asymptote} supports a more flexible mechanism for default function
+arguments than C++: they may appear anywhere in the function prototype.
+Because certain data types are implicitly cast to more sophisticated
+types (@pxref{Casts}) one can often avoid ambiguities by ordering
+function arguments from the simplest to the most complicated.
+For example, given
+@verbatim
+real f(int a=1, real b=0) {return a+b;}
+@end verbatim
+@noindent
+then @code{f(1)} returns 1.0, but @code{f(1.0)} returns 2.0.
+
+The value of a default argument is determined by evaluating the
+given @code{Asymptote} expression in the scope where the called
+function is defined.
+
+@node Named arguments, Rest arguments, Default arguments, Functions
+@subsection Named arguments
+@cindex keywords
+@cindex named arguments
+
+It is sometimes difficult to remember the order in which arguments
+appear in a function declaration. Named (keyword) arguments make calling
+functions with multiple arguments easier. Unlike in the C and C++
+languages, an assignment in a function argument is interpreted as an
+assignment to a parameter of the same name in the function signature,
+@emph{not within the local scope}. The command-line option @code{-d}
+may be used to check @code{Asymptote} code for cases where a
+named argument may be mistaken for a local assignment.
+
+When matching arguments to signatures, first all of the keywords are
+matched, then the arguments without names are matched against the
+unmatched formals as usual. For example,
+@verbatim
+int f(int x, int y) {
+ return 10x+y;
+}
+write(f(4,x=3));
+@end verbatim
+@noindent
+outputs 34, as @code{x} is already matched when we try to match the
+unnamed argument @code{4}, so it gets matched to the next item, @code{y}.
+
+For the rare occasions where it is desirable to assign a value to
+local variable within a function argument (generally @emph{not} a good
+programming practice), simply enclose the assignment in
+parentheses. For example, given the definition of @code{f} in the
+previous example,
+@verbatim
+int x;
+write(f(4,(x=3)));
+@end verbatim
+@noindent
+is equivalent to the statements
+@verbatim
+int x;
+x=3;
+write(f(4,3));
+@end verbatim
+@noindent
+and outputs 43.
+
+@cindex @code{keyword}
+@cindex keyword-only
+Parameters can be specified as ``keyword-only'' by putting @code{keyword}
+immediately before the parameter name, as in @code{int f(int keyword x)} or
+@code{int f(int keyword x=77)}. This forces the caller of the function to use
+a named argument to give a value for this parameter. That is, @code{f(x=42)}
+is legal, but @code{f(25)} is not. Keyword-only parameters must be listed
+after normal parameters in a function definition.
+
+
+As a technical detail, we point out that, since variables of the same
+name but different signatures are allowed in the same scope, the code
+@verbatim
+int f(int x, int x()) {
+ return x+x();
+}
+int seven() {return 7;}
+@end verbatim
+@noindent
+is legal in @code{Asymptote}, with @code{f(2,seven)} returning 9.
+A named argument matches the first unmatched formal of the same name, so
+@code{f(x=2,x=seven)} is an equivalent call, but @code{f(x=seven,2)}
+is not, as the first argument is matched to the first formal, and
+@code{int ()} cannot be implicitly cast to @code{int}. Default
+arguments do not affect which formal a named argument is matched to,
+so if @code{f} were defined as
+@verbatim
+int f(int x=3, int x()) {
+ return x+x();
+}
+@end verbatim
+@noindent
+then @code{f(x=seven)} would be illegal, even though @code{f(seven)}
+obviously would be allowed.
+
+@node Rest arguments, Mathematical functions, Named arguments, Functions
+@subsection Rest arguments
+@cindex rest arguments
+
+Rest arguments allow one to write functions that take a variable
+number of arguments:
+@verbatim
+// This function sums its arguments.
+int sum(... int[] nums) {
+ int total=0;
+ for(int i=0; i < nums.length; ++i)
+ total += nums[i];
+ return total;
+}
+
+sum(1,2,3,4); // returns 10
+sum(); // returns 0
+
+// This function subtracts subsequent arguments from the first.
+int subtract(int start ... int[] subs) {
+ for(int i=0; i < subs.length; ++i)
+ start -= subs[i];
+ return start;
+}
+
+subtract(10,1,2); // returns 7
+subtract(10); // returns 10
+subtract(); // illegal
+@end verbatim
+
+@cindex packing
+Putting an argument into a rest array is called @emph{packing}.
+One can give an explicit list of arguments for the rest
+argument, so @code{subtract} could alternatively be implemented as
+@verbatim
+int subtract(int start ... int[] subs) {
+ return start - sum(... subs);
+}
+@end verbatim
+
+One can even combine normal arguments with rest arguments:
+@verbatim
+sum(1,2,3 ... new int[] {4,5,6}); // returns 21
+@end verbatim
+@noindent
+@cindex unpacking
+This builds a new six-element array that is passed to @code{sum} as
+@code{nums}. The opposite operation, @emph{unpacking}, is not allowed:
+@verbatim
+subtract(... new int[] {10, 1, 2});
+@end verbatim
+@noindent
+is illegal, as the start formal is not matched.
+
+If no arguments are packed, then a zero-length array (as opposed to
+@code{null}) is bound to the rest parameter. Note that default
+arguments are ignored for rest formals and the rest argument is not
+bound to a keyword.
+
+In some cases, keyword-only parameters are helpful to avoid arguments intended
+for the rest parameter to be assigned to other parameters. For example, here
+the use of @code{keyword} is to avoid @code{pnorm(1.0,2.0,0.3)} matching
+@code{1.0} to @code{p}.
+@verbatim
+real pnorm(real keyword p=2.0 ... real[] v)
+{
+ return sum(v^p)^(1/p);
+}
+@end verbatim
+
+The overloading resolution in @code{Asymptote} is similar to the
+function matching rules used in C++. Every argument match is given a
+score. Exact matches score better than matches with casting, and
+matches with formals (regardless of casting) score better than packing
+an argument into the rest array. A candidate is maximal if all of the
+arguments score as well in it as with any other candidate. If there
+is one unique maximal candidate, it is chosen; otherwise, there is an
+ambiguity error.
+
+@verbatim
+int f(path g);
+int f(guide g);
+f((0,0)--(100,100)); // matches the second; the argument is a guide
+
+int g(int x, real y);
+int g(real x, int x);
+
+g(3,4); // ambiguous; the first candidate is better for the first argument,
+ // but the second candidate is better for the second argument
+
+int h(... int[] rest);
+int h(real x ... int[] rest);
+
+h(1,2); // the second definition matches, even though there is a cast,
+ // because casting is preferred over packing
+
+int i(int x ... int[] rest);
+int i(real x, real y ... int[] rest);
+
+i(3,4); // ambiguous; the first candidate is better for the first argument,
+ // but the second candidate is better for the second one

+* Slices:: Python-style array slices
+@end menu
+
+Appending @code{[]} to a built-in or user-defined type yields an array.
+The array element @code{i} of an array @code{A} can be accessed as @code{A[i]}.
+By default, attempts to access or assign to an array element using a negative
+index generates an error. Reading an array element with an index
+beyond the length of the array also generates an error; however,
+assignment to an element beyond the length of the array causes the
+array to be resized to accommodate the new element.
+One can also index an array @code{A} with an integer array @code{B}:
+the array @code{A[B]} is formed by indexing array @code{A} with
+successive elements of array @code{B}.
+A convenient Java-style shorthand exists for iterating over all elements of an
+array; see @ref{array iteration}.
+
+The declaration
+@verbatim
+real[] A;
+@end verbatim
+
+@noindent
+initializes @code{A} to be an empty (zero-length) array. Empty arrays should be
+distinguished from null arrays. If we say
+@verbatim
+real[] A=null;
+@end verbatim
+
+@noindent
+then @code{A} cannot be dereferenced at all (null arrays have no length
+and cannot be read from or assigned to).
+
+Arrays can be explicitly initialized like this:
+@verbatim
+real[] A={0,1,2};
+@end verbatim
+
+Array assignment in @code{Asymptote} does a shallow copy: only
+the pointer is copied (if one copy if modified, the other will be too).
+The @code{copy} function listed below provides a deep copy of an array.
+
+@cindex @code{length}
+@cindex @code{cyclic}
+@cindex @code{keys}

+@end itemize
+
+The member @code{A.length} evaluates to the length of the array.
+Setting @code{A.cyclic=true} signifies that array indices should be reduced
+modulo the current array length. Reading from or writing to a nonempty
+cyclic array never leads to out-of-bounds errors or array resizing.
+
+The member @code{A.keys} evaluates to an array of integers containing the
+indices of initialized entries in the array in ascending order. Hence, for an
+array of length @code{n} with all entries initialized, @code{A.keys} evaluates
+to @code{@{0,1,...,n-1@}}. A new keys array is produced each time
+@code{A.keys} is evaluated.
+
+The functions @code{A.push} and @code{A.append} append their
+arguments onto the end of the array, while @code{A.insert(int i ... T[] x)}
+inserts @code{x} into the array at index @code{i}.
+For convenience @code{A.push} returns the pushed item.
+The function @code{A.pop()} pops and returns the last element,
+while @code{A.delete(int i, int j=i)} deletes elements with indices in
+the range [@code{i},@code{j}], shifting the position of all higher-indexed
+elements down. If no arguments are given, @code{A.delete()} provides a
+convenient way of deleting all elements of @code{A}. The routine
+@code{A.initialized(int n)} can be used to examine whether the element
+at index @code{n} is initialized. Like all @code{Asymptote} functions,
+@code{push}, @code{append}, @code{pop}, @code{insert},
+@code{delete}, and @code{initialized} can be "pulled off" of the array
+and used on their own. For example,
+@verbatim
+int[] A={1};
+A.push(2); // A now contains {1,2}.
+A.append(A); // A now contains {1,2,1,2}.
+int f(int)=A.push;
+f(3); // A now contains {1,2,1,2,3}.
+int g()=A.pop;
+write(g()); // Outputs 3.
+A.delete(0); // A now contains {2,1,2}.
+A.delete(0,1); // A now contains {2}.
+A.insert(1,3); // A now contains {2,3}.
+A.insert(1 ... A); // A now contains {2,2,3,3}
+A.insert(2,4,5); // A now contains {2,2,4,5,3,3}.
+@end verbatim
+
+The @code{[]} suffix can also appear after the variable name; this
+is sometimes convenient for declaring a list of variables and arrays
+of the same type:
+@verbatim
+real a,A[];
+@end verbatim

+
+@end table
+
+@cindex vectorization
+@code{Asymptote} includes a full set of vectorized array instructions for
+arithmetic (including self) and logical operations. These
+element-by-element instructions are implemented in C++ code for speed. Given
+@verbatim
+real[] a={1,2};
+real[] b={3,2};
+@end verbatim
+@noindent
+then @code{a == b} and @code{a >= 2} both evaluate to the vector
+@code{@{false, true@}}.
+@cindex @code{all}
+To test whether all components of @code{a} and @code{b} agree,
+use the boolean function @code{all(a == b)}. One can also use conditionals like
+@code{(a >= 2) ? a : b}, which returns the array @code{@{3,2@}}, or
+@code{write((a >= 2) ? a : null}, which returns the array @code{@{2@}}.
+
+All of the standard built-in @code{libm} functions of signature
+@code{real(real)} also take a real array as an argument, effectively like an
+implicit call to @code{map}.
+
+As with other built-in types, arrays of the basic data types can be read
+in by assignment. In this example, the code
+@verbatim
+file fin=input("test.txt");
+real[] A=fin;
+@end verbatim
+
+@cindex @code{eof}
+@cindex @code{eol}
+@cindex @code{line}
+@cindex line mode
+@noindent
+reads real values into @code{A} until the end-of-file is reached (or an
+I/O error occurs).
+
+The virtual members @code{dimension}, @code{line}, @code{csv},
+@code{word}, and @code{read} of a file are useful for reading arrays.
+@cindex @code{line}
+For example, if line mode is set with @code{file line(bool b=true)}, then
+reading will stop once the end of the line is reached instead:
+@verbatim
+file fin=input("test.txt");
+real[] A=fin.line();
+@end verbatim
+
+@cindex reading string arrays
+@cindex @code{word}
+@cindex white-space string delimiter mode
+Since string reads by default read up to the end of line anyway, line mode
+normally has no effect on string array reads.
+However, there is a white-space delimiter mode for reading strings,
+@code{file word(bool b=true)}, which causes string reads to respect
+white-space delimiters, instead of the default end-of-line delimiter:
+@verbatim
+file fin=input("test.txt").line().word();
+real[] A=fin;
+@end verbatim
+
+@cindex @code{csv}
+@cindex comma-separated-value mode
+Another useful mode is comma-separated-value mode,
+@code{file csv(bool b=true)}, which causes reads to respect comma delimiters:
+@verbatim
+file fin=input("test.txt").csv();
+real[] A=fin;
+@end verbatim
+
+@cindex @code{dimension}
+To restrict the number of values read, use the @code{file dimension(int)}
+function:
+@verbatim
+file fin=input("test.txt");
+real[] A=fin.dimension(10);
+@end verbatim
+
+This reads 10 values into A, unless end-of-file (or end-of-line in line mode)
+occurs first. Attempting to read beyond the end of the file will produce a
+runtime error message. Specifying a value of 0 for the integer limit is
+equivalent to the previous example of reading until end-of-file (or
+end-of-line in line mode) is encountered.
+
+Two- and three-dimensional arrays of the basic data types can be read
+in like this:
+@verbatim
+file fin=input("test.txt");
+real[][] A=fin.dimension(2,3);
+real[][][] B=fin.dimension(2,3,4);
+@end verbatim
+@noindent
+
+@cindex @code{read}
+Sometimes the array dimensions are stored with the data as integer
+fields at the beginning of an array. Such 1, 2, or 3 dimensional
+arrays can be read in with the virtual member functions
+@code{read(1)}, @code{read(2)}, or @code{read(3)}, respectively:
+@verbatim
+file fin=input("test.txt");
+real[] A=fin.read(1);
+real[][] B=fin.read(2);
+real[][][] C=fin.read(3);
+@end verbatim
+
+@cindex @code{write}
+One, two, and three-dimensional arrays of the basic data types can be
+output with the functions @code{write(file,T[])},
+@code{write(file,T[][])}, @code{write(file,T[][][])}, respectively.
+
+@node Slices, , Arrays, Arrays
+@subsection Slices
+@cindex slices
+
+Asymptote allows a section of an array to be addressed as a slice
+using a Python-like syntax. If @code{A} is an array, the expression
+@code{A[m:n]} returns a new array consisting of the elements of @code{A} with
+indices from @code{m} up to but not including @code{n}. For example,
+@verbatim
+int[] x={0,1,2,3,4,5,6,7,8,9};
+int[] y=x[2:6]; // y={2,3,4,5};
+int[] z=x[5:10]; // z={5,6,7,8,9};
+@end verbatim
+
+If the left index is omitted, it is taken be @code{0}. If the right index is
+omitted it is taken to be the length of the array. If both are omitted, the
+slice then goes from the start of the array to the end, producing a non-cyclic
+deep copy of the array. For example:
+@verbatim
+int[] x={0,1,2,3,4,5,6,7,8,9};
+int[] y=x[:4]; // y={0,1,2,3}
+int[] z=x[5:]; // z={5,6,7,8,9}
+int[] w=x[:]; // w={0,1,2,3,4,5,6,7,8,9}, distinct from array x.
+@end verbatim
+
+If A is a non-cyclic array, it is illegal to use negative values for either of
+the indices. If the indices exceed the length of the array, however, they are
+politely truncated to that length.
+
+For cyclic arrays, the slice @code{A[m:n]} still consists of the cells with
+indices in the set [@code{m},@code{n}), but now negative
+values and values beyond the length of the array are allowed. The indices
+simply wrap around. For example:
+
+@verbatim
+int[] x={0,1,2,3,4,5,6,7,8,9};
+x.cyclic=true;
+int[] y=x[8:15]; // y={8,9,0,1,2,3,4}.
+int[] z=x[-5:5]; // z={5,6,7,8,9,0,1,2,3,4}
+int[] w=x[-3:17]; // w={7,8,9,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6}
+@end verbatim
+
+Notice that with cyclic arrays, it is possible to include the same element of
+the original array multiple times within a slice. Regardless of the original
+array, arrays produced by slices are always non-cyclic.
+
+If the left and right indices of a slice are the same, the result is an empty
+array. If the array being sliced is empty, the result is an empty array. Any
+slice with a left index greater than its right index will yield an error.
+
+Slices can also be assigned to, changing the value of the original array. If
+the array being assigned to the slice has a different length than the
+slice itself, elements will be inserted or removed from the array to
+accommodate it. For instance:
+@verbatim
+string[] toppings={"mayo", "salt", "ham", "lettuce"};
+toppings[0:2]=new string[] {"mustard", "pepper"};
+ // Now toppings={"mustard", "pepper", "ham", "lettuce"}
+toppings[2:3]=new string[] {"turkey", "bacon" };
+ // Now toppings={"mustard", "pepper", "turkey", "bacon", "lettuce"}
+toppings[0:3]=new string[] {"tomato"};
+ // Now toppings={"tomato", "bacon", "lettuce"}
+@end verbatim
+
+If an array is assigned to a slice of itself, a copy of the original array
+is assigned to the slice. That is, code such as @code{x[m:n]=x} is equivalent
+to @code{x[m:n]=copy(x)}. One can use the shorthand @code{x[m:m]=y} to insert
+the contents of the array @code{y} into the array @code{x} starting at the
+location just before @code{x[m]}.
+
+For a cyclic array, a slice is bridging if it addresses cells up to the end of
+the array and then continues on to address cells at the start of the array.
+For instance, if @code{A} is a cyclic array of length 10, @code{A[8:12]},
+@code{A[-3:1]}, and @code{A[5:25]} are bridging slices whereas @code{A[3:7]},
+@code{A[7:10]}, @code{A[-3:0]} and @code{A[103:107]} are not. Bridging slices
+can only be assigned to if the number of elements in the slice is exactly equal
+to the number of elements we are assigning to it. Otherwise, there is no clear
+way to decide which of the new entries should be @code{A[0]} and an error is
+reported. Non-bridging slices may be assigned an array of any length.
+
+For a cyclic array @code{A} an expression of the form
+@code{A[A.length:A.length]} is equivalent to the expression @code{A[0:0]} and
+so assigning to this slice will insert values at the start of the array.
+@code{A.append()} can be used to insert values at the end of the array.
+
+It is illegal to assign to a slice of a cyclic array that repeats any of the
+cells.

+@section Casts
+@cindex casts
+@cindex implicit casts
+@cindex @code{explicit}
+
+@code{Asymptote} implicitly casts @code{int} to @code{real}, @code{int} to
+@code{pair}, @code{real} to @code{pair}, @code{pair} to @code{path},
+@code{pair} to @code{guide}, @code{path} to @code{guide}, @code{guide}

+@code{path} to @code{path[]}, and @code{guide} to @code{path[]},
+along with various three-dimensional casts defined in module @code{three}.
+Implicit casts are automatically attempted on assignment and when
+trying to match function calls with possible function
+signatures. Implicit casting can be inhibited by declaring individual
+arguments @code{explicit} in the function signature, say to avoid an
+ambiguous function call in the following example, which outputs 0:
+@verbatim
+int f(pair a) {return 0;}
+int f(explicit real x) {return 1;}
+
+write(f(0));
+@end verbatim
+
+@cindex explicit casts
+Other conversions, say @code{real} to @code{int} or
+@code{real} to @code{string}, require an explicit cast:
+@verbatim
+int i=(int) 2.5;
+string s=(string) 2.5;
+
+real[] a={2.5,-3.5};
+int[] b=(int []) a;
+write(stdout,b); // Outputs 2,-3
+@end verbatim
+In situations where casting from a string to a type @code{T} fails,
+an uninitialized variable is returned; this condition can be detected
+with the function @code{bool initialized(T);}
+@verbatim
+int i=(int) "2.5";

+Casting to user-defined types is also possible using @code{operator cast}:

+ real angle;
+}
+
+pair operator cast(rpair x) {
+ return (x.radius*cos(x.angle),x.radius*sin(x.angle));

+@end verbatim
+
+One must use care when defining new cast operators. Suppose that in some
+code one wants all integers to represent multiples of 100. To convert them
+to reals, one would first want to multiply them by 100. However, the
+straightforward implementation
+@verbatim
+real operator cast(int x) {return x*100;}
+@end verbatim
+@noindent
+is equivalent to an infinite recursion, since the result @code{x*100}
+needs itself to be cast from an integer to a real. Instead, we want to
+use the standard conversion of int to real:
+@verbatim
+real convert(int x) {return x*100;}
+real operator cast(int x)=convert;
+@end verbatim
+
+@cindex @code{operator ecast}
+Explicit casts are implemented similarly, with @code{operator ecast}.

+@section Import
+@cindex @code{access}
+While @code{Asymptote} provides many features by default,
+some applications require specialized features contained in
+external @code{Asymptote} modules. For instance, the lines
+@verbatim
+access graph;
+graph.axes();
+@end verbatim
+@noindent
+draw @math{x} and @math{y} axes on a two-dimensional graph. Here, the
+command looks up the module under the name @code{graph} in a global dictionary
+of modules and puts it in a new variable named @code{graph}.
+The module is a structure, and we can refer to its fields as we usually
+would with a structure.
+
+@cindex @code{from}
+Often, one wants to use module functions without having to specify
+the module name. The code
+@verbatim
+from graph access axes;
+@end verbatim
+@noindent
+adds the @code{axes} field of @code{graph} into the local name space,
+so that subsequently, one can just write @code{axes()}. If the given name
+is overloaded, all types and variables of that name are added. To add
+more than one name, just use a comma-separated list:
+@verbatim
+from graph access axes, xaxis, yaxis;
+@end verbatim
+@noindent
+Wild card notation can be used to add all non-private fields and types of a
+module to the local name space:
+
+@verbatim
+from graph access *;
+@end verbatim
+
+@cindex @code{unravel}
+Similarly, one can add the non-private fields and types of a structure
+to the local environment with the @code{unravel} keyword:
+@verbatim
+struct matrix {
+ real a,b,c,d;
+}
+
+real det(matrix m) {
+ unravel m;
+ return a*d-b*c;
+}
+@end verbatim
+Alternatively, one can unravel selective fields:
+@verbatim
+real det(matrix m) {
+ from m unravel a,b,c as C,d;
+ return a*d-b*C;
+}
+@end verbatim
+
+@cindex @code{import}
+@cindex @code{access}
+The command
+@verbatim
+import graph;
+@end verbatim
+is a convenient abbreviation for the commands
+@verbatim
+access graph;
+unravel graph;
+@end verbatim
+That is, @code{import graph} first loads a module into a structure called
+@code{graph} and then adds its non-private fields and types to the
+local environment. This way, if a member variable (or function) is
+overwritten with a local variable (or function of the same signature),
+the original one can still be accessed by qualifying it with the
+module name.
+
+Wild card importing will work fine in most cases, but one does not usually know
+all of the internal types and variables of a module, which can also
+change as the module writer adds or changes features of the module.
+As such, it is prudent to add @code{import} commands at the start of an
+@code{Asymptote} file, so that imported names won't shadow locally
+defined functions. Still, imported names may shadow other imported
+names, depending on the order in which they were imported, and
+imported functions may cause overloading resolution problems if they
+have the same name as local functions defined later.
+
+@cindex @code{as}
+To rename modules or fields when adding them to the local environment, use
+@code{as}:
+@verbatim
+access graph as graph2d;
+from graph access xaxis as xline, yaxis as yline;
+@end verbatim
+
+The command
+@verbatim
+import graph as graph2d;
+@end verbatim
+is a convenient abbreviation for the commands
+@verbatim
+access graph as graph2d;
+unravel graph2d;
+@end verbatim
+
+Except for a few built-in modules, such as @code{settings}, all modules
+are implemented as @code{Asymptote} files. When looking up a module
+that has not yet been loaded, @code{Asymptote} searches the standard
+search paths (@pxref{Search paths}) for the matching file. The file
+corresponding to that name is read and the code within it is interpreted
+as the body of a structure defining the module.
+
+If the file name contains
+nonalphanumeric characters, enclose it with quotation marks:
+
+@noindent
+@code{access "@value{Datadir}/asymptote/graph.asy" as graph;}
+
+@noindent
+@code{from "@value{Datadir}/asymptote/graph.asy" access axes;}
+
+@noindent
+@code{import "@value{Datadir}/asymptote/graph.asy" as graph;}
+
+@cindex @acronym{URL}
+@cindex @acronym{libcurl}
+If @code{Asymptote} is compiled with support for @code{libcurl},
+the file name can even be a @acronym{URL}:
+@noindent
+@code{import "https://raw.githubusercontent.com/vectorgraphics/asymptote/HEAD/doc/axis3.asy" as axis3;}
+
+It is an error if modules import themselves (or each other in a cycle).
+The module name to be imported must be known at compile time.
+
+@cindex runtime imports
+@cindex @code{eval}
+However, you can import an @code{Asymptote} module determined by the
+string @code{s} at runtime like this:
+@verbatim
+eval("import "+s,true);
+@end verbatim
+
+@cindex @code{asy}
+To conditionally execute an array of asy files, use
+@verbatim
+void asy(string format, bool overwrite ... string[] s);
+@end verbatim
+The file will only be processed, using output format @code{format}, if
+overwrite is @code{true} or the output file is missing.
+
+One can evaluate an @code{Asymptote} expression (without any return
+value, however) contained in the string @code{s} with:
+@cindex @code{eval}
+@verbatim
+void eval(string s, bool embedded=false);
+@end verbatim
+It is not necessary to terminate the string @code{s} with a semicolon.
+If @code{embedded} is @code{true}, the string will be evaluated
+at the top level of the current environment.
+If @code{embedded} is @code{false} (the default), the string
+will be evaluated in an independent environment, sharing the same
+@code{settings} module (@pxref{settings}).
+
+@cindex @code{quote}
+One can evaluate arbitrary @code{Asymptote} code (which may
+contain unescaped quotation marks) with the command
+@verbatim
+void eval(code s, bool embedded=false);
+@end verbatim
+Here @code{code} is a special type used with @code{quote @{@}}
+to enclose @code{Asymptote code} like this:
+@verbatim
+real a=1;
+code s=quote {
+ write(a);
+};
+eval(s,true); // Outputs 1
+@end verbatim
+
+One application of @code{eval} is the creation of parametrized Asymptote
+code, such as a map from one type to another (@pxref{map}).
+
+@cindex @code{include}
+To include the contents of an existing file @code{graph} verbatim (as if the
+contents of the file were inserted at that point), use one of the forms:
+@verbatim
+include graph;
+@end verbatim
+
+@noindent
+@code{include "@value{Datadir}/asymptote/graph.asy";}
+
+To list all global functions and variables defined in a module named
+by the contents of the string @code{s}, use the function
+@verbatim
+void list(string s, bool imports=false);
+@end verbatim
+@noindent
+Imported global functions and variables are also listed if
+@code{imports} is @code{true}.
+
+@node Static, , Import, Programming
+@section Static
+@cindex @code{static}
+
+Static qualifiers allocate the memory address of a variable in a higher
+enclosing level.
+
+For a function body, the variable is allocated in the block where the
+function is defined; so in the code
+@verbatim
+struct s {
+ int count() {
+ static int c=0;
+ ++c;
+ return c;
+ }
+}
+@end verbatim
+
+@noindent
+there is one instance of the variable @code{c} for each
+object @code{s} (as opposed to each call of @code{count}).
+
+Similarly, in
+@verbatim
+int factorial(int n) {
+ int helper(int k) {
+ static int x=1;
+ x *= k;
+ return k == 1 ? x : helper(k-1);
+ }
+ return helper(n);
+}
+@end verbatim
+
+@noindent
+there is one instance of @code{x} for every call to
+@code{factorial} (and not for every call to @code{helper}), so this is
+a correct, but ugly, implementation of factorial.
+
+Similarly, a static variable declared within a structure is allocated in
+the block where the structure is defined. Thus,
+@verbatim
+struct A {
+ struct B {
+ static pair z;
+ }
+}
+@end verbatim
+
+@noindent
+creates one object @code{z} for each object of type @code{A} created.
+
+In this example,
+@verbatim
+int pow(int n, int k) {
+ struct A {
+ static int x=1;
+ void helper() {
+ x *= n;
+ }
+ }
+ for(int i=0; i < k; ++i) {
+ A a;
+ a.helper();
+ }
+ return A.x;
+}
+@end verbatim
+
+@noindent
+there is one instance of @code{x} for each call to @code{pow}, so this
+is an ugly implementation of exponentiation.
+
+Loop constructs allocate a new frame in every iteration. This is so that
+higher-order functions can refer to variables of a specific iteration of a
+loop:
+@verbatim
+void f();
+for(int i=0; i < 10; ++i) {
+ int x=i;
+ if(x==5) {
+ f=new void() {write(x);};
+ }
+}
+f();
+@end verbatim
+
+Here, every iteration of the loop has its own variable @code{x}, so @code{f()}
+will write @code{5}. If a variable in a loop is declared static, it will be
+allocated where the enclosing function or structure was defined (just as if it
+were declared static outside of the loop). For instance, in:
+@verbatim
+void f() {
+ static int x;
+ for(int i=0; i < 10; ++i) {
+ static int y;
+ }
+}
+@end verbatim
+@noindent
+both @code{x} and @code{y} will be allocated in the same place, which is
+also where @code{f} is allocated.
+
+Statements may also be declared static, in which case they are run at the place
+where the enclosing function or structure is defined.
+Declarations or statements not enclosed in a function or structure definition
+are already at the top level, so static modifiers are meaningless. A warning is
+given in such a case.
+
+Since structures can have static fields, it is not always clear for a qualified
+name whether the qualifier is a variable or a type. For instance, in:
+
+@verbatim
+struct A {
+ static int x;
+}
+pair A;
+
+int y=A.x;
+@end verbatim
+@noindent
+does the @code{A} in @code{A.x} refer to the structure or to the pair variable.
+It is the convention in Asymptote that, if there is a non-function variable with
+the same name as the qualifier, the qualifier refers to that variable, and not
+to the type. This is regardless of what fields the variable actually possesses.

+@cindex @code{asymptote.sty}
+
+@code{Asymptote} comes with a convenient @code{LaTeX} style file
+@code{asymptote.sty} (v1.36 or later required) that makes @code{LaTeX}
+@code{Asymptote}-aware. Entering @code{Asymptote} code
+directly into the @code{LaTeX} source file, at the point where it is
+needed, keeps figures organized and avoids the need to invent new file
+names for each figure. Simply add the line
+@code{\usepackage@{asymptote@}} at the beginning of your file
+and enclose your @code{Asymptote} code within a
+@code{\begin@{asy@}...\end@{asy@}} environment. As with the
+@code{LaTeX} @code{comment} environment, the @code{\end@{asy@}} command
+must appear on a line by itself, with no trailing commands/comments.
+A blank line is not allowed after @code{\begin@{asy@}}.
+
+The sample @code{LaTeX} file below, named @code{latexusage.tex}, can
+be run as follows:
+@verbatim
+latex latexusage
+asy latexusage-*.asy
+latex latexusage
+@end verbatim
+
+@noindent
+or
+@verbatim
+pdflatex latexusage
+asy latexusage-*.asy
+pdflatex latexusage
+@end verbatim
+@noindent
+To switch between using inline Asymptote code with @code{latex} and
+@code{pdflatex} you may first need to remove the files @code{latexusage-*.tex}.
+
+@cindex @code{latexmk}
+@cindex @code{perl}
+An even better method for processing a @code{LaTeX} file with embedded
+@code{Asymptote} code is to use the @code{latexmk} utility from
+@quotation
+@url{http://mirror.ctan.org/support/latexmk/}
+@end quotation
+@noindent
+after putting the contents of
+@url{https://raw.githubusercontent.com/vectorgraphics/asymptote/HEAD/doc/latexmkrc}
+@noindent
+in a file @code{latexmkrc} in the same directory. The command
+@verbatim
+latexmk -pdf latexusage
+@end verbatim
+@noindent
+will then call @code{Asymptote} automatically, recompiling only the figures
+that have changed. Since each figure is compiled in a separate
+system process, this method also tends to use less memory.
+To store the figures in a separate directory named @code{asy}, one can define
+@verbatim
+\def\asydir{asy}
+@end verbatim
+in @code{latexusage.tex} and put the contents of
+@url{https://raw.githubusercontent.com/vectorgraphics/asymptote/HEAD/doc/latexmkrc_asydir}

+External @code{Asymptote} code can be included with
+@cindex @code{asyinclude}
+@verbatim
+\asyinclude[<options>]{<filename.asy>}

+Three-dimensional @acronym{PRC} files may either be embedded within
+the page (the default) or attached as annotated (but printable)
+attachments, using the @code{attach} option and the @code{attachfile2}
+(or older @code{attachfile}) @code{LaTeX} package.
+The @code{inline} option generates
+inline @code{LaTeX} code instead of @acronym{EPS} or @acronym{PDF}
+files. This makes 2D LaTeX symbols visible to the
+@code{\begin@{asy@}...\end@{asy@}} environment. In this mode,
+Asymptote correctly aligns 2D LaTeX symbols defined outside of
+@code{\begin@{asy@}...\end@{asy@}}, but treats their size as zero; an
+optional second string can be given to @code{Label} to provide an
+estimate of the unknown label size.
+
+Note that if the @code{latex} @TeX{} engine is used with the
+@code{inline} option, labels might not show up in @acronym{DVI}
+viewers that cannot handle raw @code{PostScript} code. One can use
+@code{dvips}/@code{dvipdf} to produce @code{PostScript}/@acronym{PDF}
+output (we recommend using the modified version of @code{dvipdf} in

+@end verbatim
+
+This routine can be used to draw on picture @code{pic} a general axis
+based on an arbitrary path @code{g}, using pen @code{p}.
+One can optionally label the axis with Label @code{L} and add an arrow
+@code{arrow}. The tick type is given by @code{ticks}.
+The optional integer array @code{divisor} specifies what tick divisors
+to try in the attempt to produce uncrowded tick labels. A @code{true}
+value for the flag @code{opposite} identifies an unlabelled secondary
+axis (typically drawn opposite a primary axis). The axis is drawn before
+any existing objects in @code{pic} unless @code{above=true}.
+The tick locator @code{ticklocate} is constructed by the routine
+@verbatim

+ real tickmin=-infinity, real tickmax=infinity,
+ real time(real)=null, pair dir(real)=zero);

+
+@item These routines are useful for manually putting ticks and labels on axes
+(if the variable @code{Label} is given as the @code{Label}

+Here are some simple examples of two-dimensional graphs:
+
+@enumerate
+
+@cindex textbook graph
+@item This example draws a textbook-style graph of
+@math{y=} exp@math{(x)}, with the @math{y} axis starting at @math{y=0}:
+@verbatiminclude exp.asy
+@sp 1
+@center @image{./exp}
+
+
+@item The next example draws a scientific-style graph with a legend.
+The position of the legend can be adjusted either explicitly or by using the
+graphical user interface (@pxref{GUI}). If an
+@code{UnFill(real xmargin=0, real ymargin=xmargin)} or
+@code{Fill(pen)} option is specified to @code{add}, the legend will obscure
+any underlying objects. Here we illustrate how to clip the portion of
+the picture covered by a label:
+
+@cindex scientific graph
+@verbatiminclude lineargraph0.asy
+@sp 1
+@center @image{./lineargraph0}
+
+@cindex @code{attach}
+To specify a fixed size for the graph proper, use @code{attach}:
+@verbatiminclude lineargraph.asy
+
+@cindex @code{legend}
+A legend can have multiple entries per line:
+@verbatiminclude legend.asy
+@sp 1
+@center @image{./legend}
+
+@item This example draws a graph of one array versus another (both of
+the same size) using custom tick locations and a smaller font size for
+the tick labels on the @math{y} axis.
+@verbatiminclude datagraph.asy
+@sp 1
+@center @image{./datagraph}
+
+@item This example shows how to graph columns of data read from a file.
+@verbatiminclude filegraph.asy

+@cindex @code{marker}
+@cindex @code{marknodes}
+@cindex @code{markuniform}
+@cindex @code{mark}
+@cindex path markers
+@anchor{pathmarkers}
+@item The next example draws two graphs of an array of coordinate pairs,
+using frame alignment and data markers. In the left-hand graph, the
+markers, constructed with
+@verbatim
+marker marker(path g, markroutine markroutine=marknodes,
+ pen p=currentpen, filltype filltype=NoFill,
+ bool above=true);
+@end verbatim
+using the path @code{unitcircle} (@pxref{filltype}), are drawn
+below each node. Any frame can be converted to a marker, using
+@anchor{marker}
+@verbatim
+marker marker(frame f, markroutine markroutine=marknodes,
+ bool above=true);
+@end verbatim
+In the right-hand graph, the unit @math{n}-sided regular polygon
+@code{polygon(int n)} and the unit @math{n}-point cyclic cross
+@code{cross(int n, bool round=true, real r=0)} (where @code{r} is an
+optional ``inner'' radius) are used to build a custom marker frame.
+@anchor{markuniform}
+Here @code{markuniform(bool centered=false, int n, bool rotated=false)}
+adds this frame at @code{n} uniformly spaced points along the arclength
+of the path, optionally rotated by the angle of the local tangent to the path
+(if centered is true, the frames will be centered within @code{n} evenly
+spaced arclength intervals). Alternatively, one can use
+markroutine @code{marknodes} to request that the marks be placed at each
+Bezier node of the path, or
+markroutine @code{markuniform(pair z(real t), real a, real b, int n)}
+to place marks at points @code{z(t)} for n evenly spaced values of
+@code{t} in @code{[a,b]}.
+
+These markers are predefined:
+@verbatim
+marker[] Mark={
+ marker(scale(circlescale)*unitcircle),
+ marker(polygon(3)),marker(polygon(4)),
+ marker(polygon(5)),marker(invert*polygon(3)),
+ marker(cross(4)),marker(cross(6))
+};
+
+marker[] MarkFill={
+ marker(scale(circlescale)*unitcircle,Fill),marker(polygon(3),Fill),
+ marker(polygon(4),Fill),marker(polygon(5),Fill),
+ marker(invert*polygon(3),Fill)
+};
+@end verbatim
+
+The example also illustrates the @code{errorbar} routines:
+
+@verbatim
+void errorbars(picture pic=currentpicture, pair[] z, pair[] dp,
+ pair[] dm={}, bool[] cond={}, pen p=currentpen,
+ real size=0);
+
+void errorbars(picture pic=currentpicture, real[] x, real[] y,
+ real[] dpx, real[] dpy, real[] dmx={}, real[] dmy={},
+ bool[] cond={}, pen p=currentpen, real size=0);
+@end verbatim
+
+@noindent
+Here, the positive and negative extents of the error are given by the
+absolute values of the elements of the pair array @code{dp} and the
+optional pair array @code{dm}. If @code{dm} is not specified, the
+positive and negative extents of the error are assumed to be equal.
+@anchor{errorbars}

+@item A custom mark routine can be also be specified:

+
+@item This example shows how to label an axis with arbitrary strings.
+@verbatiminclude monthaxis.asy

+@end verbatim
+@noindent
+and the analogous function @code{ylimits} can be uncommented
+to set the respective axes limits for picture @code{pic} to the
+specified @code{min} and @code{max} values. Alternatively, the function
+@verbatim
+void limits(picture pic=currentpicture, pair min, pair max, bool crop=NoCrop);
+@end verbatim
+can be used to limit the axes to the box having opposite vertices at
+the given pairs). Existing objects in picture @code{pic} will be cropped to lie
+within the given limits if @code{crop}=@code{Crop}. The function
+@code{crop(picture pic)} can be used to crop a graph to the current
+graph limits.
+@verbatiminclude parametricgraph.asy
+@sp 1
+@center @image{./parametricgraph}
+
+@cindex scaled graph
+The next example illustrates how one can extract a common axis scaling
+factor.
+@verbatiminclude scaledgraph.asy
+@sp 1
+@center @image{./scaledgraph}
+
+@anchor{automatic scaling}
+@cindex automatic scaling
+@cindex @code{scale}
+@cindex @code{Linear}
+@cindex @code{Log}
+@cindex automatic scaling
+Axis scaling can be requested and/or automatic selection of the
+axis limits can be inhibited with one of these @code{scale} routines:
+@verbatim
+void scale(picture pic=currentpicture, scaleT x, scaleT y);
+
+void scale(picture pic=currentpicture, bool xautoscale=true,
+ bool yautoscale=xautoscale, bool zautoscale=yautoscale);
+@end verbatim
+
+This sets the scalings for picture @code{pic}. The @code{graph} routines
+accept an optional @code{picture} argument for determining the appropriate
+scalings to use; if none is given, it uses those set for
+@code{currentpicture}.
+
+Two frequently used scaling routines
+@code{Linear} and @code{Log} are predefined in @code{graph}.
+
+All picture coordinates (including those in paths and those given
+to the @code{label} and @code{limits} functions) are always treated as linear
+(post-scaled) coordinates. Use
+@cindex @code{Scale}
+@verbatim
+pair Scale(picture pic=currentpicture, pair z);
+@end verbatim
+to convert a graph coordinate into a scaled picture coordinate.
+
+The @math{x} and @math{y} components can be individually scaled using
+the analogous routines
+@verbatim
+real ScaleX(picture pic=currentpicture, real x);
+real ScaleY(picture pic=currentpicture, real y);
+@end verbatim
+
+The predefined scaling routines can be given two optional boolean arguments:
+@code{automin=false} and @code{automax=automin}. These default to
+@code{false} but can be respectively set to @code{true} to enable
+automatic selection of "nice" axis minimum and maximum values. The
+@code{Linear} scaling can also take as optional final arguments a
+multiplicative scaling factor and intercept (e.g.@ for a depth axis,
+@code{Linear(-1)} requests axis reversal).
+
+@cindex logarithmic graph
+@cindex log-log graph
+For example, to draw a log/log graph of a function, use @code{scale(Log,Log)}:
+@verbatiminclude loggraph.asy
+@sp 1
+@center @image{./loggraph}
+
+@cindex grid
+By extending the ticks, one can easily produce a logarithmic grid:
+@verbatiminclude loggrid.asy
+
+@sp 1
+@center @image{./loggrid}
+
+One can also specify custom tick locations and formats for logarithmic axes:
+@verbatiminclude logticks.asy
+@sp 1
+@center @image{./logticks}
+
+@cindex @code{log2} graph
+It is easy to draw logarithmic graphs with respect to other bases:
+@verbatiminclude log2graph.asy
+@sp 1
+@center @image{./log2graph}
+
+@cindex broken axis
+Here is an example of "broken" linear @math{x} and logarithmic
+@math{y} axes that omit the segments [3,8] and [100,1000], respectively.
+In the case of a logarithmic axis, the break endpoints are automatically
+rounded to the nearest integral power of the base.
+@verbatiminclude brokenaxis.asy
+@sp 1
+@center @image{./brokenaxis}
+
+@cindex secondary axis
+@cindex @code{secondaryX}
+@cindex @code{secondaryY}
+@item @code{Asymptote} can draw secondary axes with the routines
+@verbatim
+picture secondaryX(picture primary=currentpicture, void f(picture));
+picture secondaryY(picture primary=currentpicture, void f(picture));
+@end verbatim
+
+In this example, @code{secondaryY} is used to draw a secondary linear
+@math{y} axis against a primary logarithmic @math{y} axis:
+@verbatiminclude Bode.asy
+@sp 1
+@center @image{./Bode}
+
+A secondary logarithmic @math{y} axis can be drawn like this:
+@verbatiminclude secondaryaxis.asy
+@sp 1
+@center @image{./secondaryaxis}
+
+@item Here is a histogram example, which uses the @code{stats} module.
+@cindex @code{axis}
+@verbatiminclude histogram.asy
+@sp 1
+@center @image{./histogram}
+
+@item Here is an example of reading column data in from a file and a
+least-squares fit, using the @code{stats} module.
+@cindex @code{leastsquares}
+@verbatiminclude leastsquares.asy

+@item Here is an example that illustrates the general @code{axis} routine.
+@cindex @code{axis}
+@verbatiminclude generalaxis.asy
+@sp 1
+@center @image{./generalaxis}
+
+@item To draw a vector field of @code{n} arrows evenly spaced along
+the arclength of a path, use the routine
+@cindex @code{vectorfield}
+@verbatim
+picture vectorfield(path vector(real), path g, int n, bool truesize=false,
+ pen p=currentpen, arrowbar arrow=Arrow);
+@end verbatim
+as illustrated in this simple example of a flow field:
+@verbatiminclude flow.asy
+@sp 1
+@center @image{./flow}
+
+@item To draw a vector field of @code{nx}@math{\times}@code{ny} arrows
+in @code{box(a,b)}, use the routine

+@verbatim
+picture vectorfield(path vector(pair), pair a, pair b,
+ int nx=nmesh, int ny=nx, bool truesize=false,
+ real maxlength=truesize ? 0 : maxlength(a,b,nx,ny),

+@code{Asymptote} can also generate color density images
+and palettes. The following palettes are predefined in
+@code{palette.asy}:
+
+@table @code
+
+@cindex @code{Grayscale}
+@item pen[] Grayscale(int NColors=256)
+a grayscale palette;
+
+@cindex @code{Rainbow}

+a rainbow spectrum;
+
+@cindex @code{BWRainbow}

+a rainbow spectrum tapering off to black/white at the ends;
+
+@cindex @code{BWRainbow2}
+@item pen[] BWRainbow2(int NColors=32761)
+a double rainbow palette tapering off to black/white at the ends, with
+a linearly scaled intensity.
+
+@cindex @code{Wheel}
+@item pen[] Wheel(int NColors=32766)
+a full color wheel palette;
+
+@cindex @code{Gradient}
+@item pen[] Gradient(int NColors=256 ... pen[] p)
+a palette varying linearly over the specified array of pens, using
+NColors in each interpolation interval;
+
+@end table
+
+The function @code{cmyk(pen[] Palette)} may be used to convert any
+of these palettes to the @acronym{CMYK} colorspace.
+
+A color density plot using palette @code{palette} can be generated from
+a function @code{f}(@math{x},@math{y}) and added to a picture @code{pic}:
+@cindex @code{image}
+@verbatim
+bounds image(picture pic=currentpicture, real f(real, real),
+ range range=Full, pair initial, pair final,
+ int nx=ngraph, int ny=nx, pen[] palette, bool antialias=false)
+@end verbatim
+The function @code{f} will be sampled at @code{nx} and @code{ny}
+evenly spaced points over a rectangle defined by the points
+@code{initial} and @code{final}, respecting the current graphical
+scaling of @code{pic}. The color space is scaled according to the
+@math{z} axis scaling (@pxref{automatic scaling}). A bounds structure
+for the function values is returned:
+@verbatim
+struct bounds {
+ real min;
+ real max;
+ // Possible tick intervals:
+ int[] divisor;
+}
+@end verbatim
+@noindent
+This information can be used for generating an optional palette bar.
+The palette color space corresponds to a range of values specified by
+the argument @code{range}, which can be @code{Full}, @code{Automatic},
+or an explicit range @code{Range(real min, real max)}.
+Here @code{Full} specifies a range varying from the
+minimum to maximum values of the function over the sampling interval,
+while @code{Automatic} selects "nice" limits.
+The example @code{@uref{https://asymptote.sourceforge.io/gallery/2Dgraphs/imagecontour.svg,,imagecontour}@uref{https://asymptote.sourceforge.io/gallery/2Dgraphs/imagecontour.asy,,.asy}} illustrates how level sets
+(contour lines) can be drawn on a color density plot (@pxref{contour}).
+
+A color density plot can also be generated from an explicit real[][]
+array @code{data}:
+@cindex @code{image}
+@verbatim
+bounds image(picture pic=currentpicture, real[][] f, range range=Full,
+ pair initial, pair final, pen[] palette,
+ bool transpose=(initial.x < final.x && initial.y < final.y),
+ bool copy=true, bool antialias=false);
+@end verbatim
+@noindent
+If the initial point is to the left and below the final point,
+by default the array indices are interpreted according to the
+Cartesian convention (first index: @math{x}, second index: @math{y})
+rather than the usual matrix convention (first index: @math{-y},
+second index: @math{x}).
+
+To construct an image from an array of irregularly spaced points
+and an array of values @code{f} at these points, use one of the routines
+@verbatim
+bounds image(picture pic=currentpicture, pair[] z, real[] f,
+ range range=Full, pen[] palette)
+bounds image(picture pic=currentpicture, real[] x, real[] y, real[] f,
+ range range=Full, pen[] palette)
+@end verbatim
+
+An optionally labelled palette bar may be generated with the routine
+@verbatim
+void palette(picture pic=currentpicture, Label L="", bounds bounds,
+ pair initial, pair final, axis axis=Right, pen[] palette,
+ pen p=currentpen, paletteticks ticks=PaletteTicks,
+ bool copy=true, bool antialias=false);
+@end verbatim
+The color space of @code{palette} is taken to be over bounds @code{bounds} with
+scaling given by the @math{z} scaling of @code{pic}.
+The palette orientation is specified by @code{axis}, which may be one of
+@code{Right}, @code{Left}, @code{Top}, or @code{Bottom}.
+The bar is drawn over the rectangle from @code{initial} to @code{final}.
+The argument @code{paletteticks} is a special tick type (@pxref{ticks})
+that takes the following arguments:
+@verbatim
+paletteticks PaletteTicks(Label format="", ticklabel ticklabel=null,
+ bool beginlabel=true, bool endlabel=true,
+ int N=0, int n=0, real Step=0, real step=0,
+ pen pTick=nullpen, pen ptick=nullpen);
+@end verbatim
+
+The image and palette bar can be fit to a frame and added and
+optionally aligned to a picture at the desired location:
+
+@anchor{image}
+@verbatiminclude image.asy
+@sp 1
+@center @image{./image}
+
+Here is an example that uses logarithmic scaling of the function values:
+
+@anchor{logimage}
+@verbatiminclude logimage.asy
+@sp 1
+@center @image{./logimage}
+
+One can also draw an image directly from a two-dimensional pen array
+or a function @code{pen f(int, int)}:
+@verbatim
+void image(picture pic=currentpicture, pen[][] data,
+ pair initial, pair final,
+ bool transpose=(initial.x < final.x && initial.y < final.y),
+ bool copy=true, bool antialias=false);
+void image(picture pic=currentpicture, pen f(int, int), int width, int height,
+ pair initial, pair final,
+ bool transpose=(initial.x < final.x && initial.y < final.y),
+ bool antialias=false);
+@end verbatim

+For convenience, the module @code{palette} also defines functions
+that may be used to construct a pen array from a given function and palette:

+This module fully extends the notion of guides and paths in @code{Asymptote}
+to three dimensions. It introduces the new types guide3, path3, and surface.
+Guides in three dimensions are specified with the same syntax as in two
+dimensions except that triples @code{(x,y,z)} are used in place of pairs
+@code{(x,y)} for the nodes and direction specifiers. This
+generalization of John Hobby's spline algorithm is shape-invariant under
+three-dimensional rotation, scaling, and shifting, and reduces in the
+planar case to the two-dimensional algorithm used in @code{Asymptote},
+@code{MetaPost}, and @code{MetaFont} [cf.@ J. C. Bowman, Proceedings in
+Applied Mathematics and Mechanics, 7:1, 2010021-2010022 (2007)].
+
+For example, a unit circle in the @math{XY} plane may be filled and
+drawn like this:
+@verbatiminclude unitcircle3.asy
+@sp 1
+@center @image{./unitcircle3}
+@noindent
+and then distorted into a saddle:
+@verbatiminclude saddle.asy
+@sp 1
+@center @image{./saddle}
+@noindent
+
+Module @code{three} provides constructors for converting two-dimensional
+paths to three-dimensional ones, and vice-versa:
+@cindex @code{path3}
+@cindex @code{path}
+@verbatim

+A Bezier surface, the natural two-dimensional generalization of Bezier
+curves, is defined in @code{three_surface.asy} as a structure
+containing an array of Bezier patches. Surfaces may drawn with one of
+the routines
+@verbatim

+
+@end verbatim
+The parameters @code{nu} and @code{nv} specify the number of subdivisions
+for drawing optional mesh lines for each Bezier patch. The optional
+@code{name} parameter is used as a prefix for naming the surface
+patches in the @acronym{PRC} model tree.

+vertex-dependent colors, which are supported by
+@code{Asymptote}'s native @code{OpenGL}/@code{WebGL} renderers
+and the two-dimensional vector output format (@code{settings.render=0}). Since
+the @acronym{PRC} output format does not currently support vertex
+shading of Bezier surfaces, @acronym{PRC} patches are shaded with the mean of the four vertex colors.
+
+@cindex @code{surface}
+@cindex @code{planar}
+@cindex @code{Bezier patch}
+@cindex @code{Bezier triangle}
+A surface can be constructed from a cyclic @code{path3} with the constructor
+@verbatim
+surface surface(path3 external, triple[] internal=new triple[],
+ pen[] colors=new pen[], bool3 planar=default);
+@end verbatim
+@noindent
+and then filled:

+draw(surface(unitcircle3),red,nolight);
+draw(surface(unitcircle3,new pen[] {red,green,blue,black}),nolight);
+@end verbatim
+@noindent
+The first example draws a Bezier patch and the second example draws
+a Bezier triangle. The third and fourth examples are planar surfaces.
+The last example constructs a patch with vertex-specific colors.
+A three-dimensional planar surface in the plane @code{plane} can be
+constructed from a two-dimensional cyclic path @code{g} with the constructor
+@cindex @code{surface}
+@verbatim
+surface surface(path p, triple plane(pair)=XYplane);
+@end verbatim
+@noindent
+and then filled:
+@verbatim
+draw(surface((0,0)--E+2N--2E--E+N..0.2E..cycle),red);
+@end verbatim
+@noindent
+@cindex @code{bezulate}
+Planar Bezier surfaces patches are constructed using Orest Shardt's
+@code{bezulate} routine, which decomposes (possibly nonsimply
+connected) regions bounded (according to the @code{zerowinding} fill rule)
+by simple cyclic paths (intersecting only at the endpoints)
+into subregions bounded by cyclic paths of length @code{4} or less.
+
+A more efficient routine also exists for drawing tessellations
+composed of many 3D triangles, with specified vertices, and optional
+normals or vertex colors:
+@cindex @code{draw}
+@cindex @code{triangles}
+@cindex @code{tessellation}
+@verbatim
+void draw(picture pic=currentpicture, triple[] v, int[][] vi,
+ triple[] n={}, int[][] ni=vi, material m=currentpen, pen[] p={},
+ int[][] pi=vi, light light=currentlight);
+@end verbatim
+Here, the triple array @code{v} lists the (typically distinct) vertices, while
+the array @code{vi} contains integer arrays of length 3 containing
+the indices of the elements in @code{v} that form the vertices of each
+triangle. Similarly, the arguments @code{n} and @code{ni} contain
+optional normal data and @code{p} and @code{pi} contain optional pen
+vertex data. If more than one normal or pen is specified for a vertex, the
+last one specified is used.
+An example of this tessellation facility is given in @code{@uref{https://asymptote.sourceforge.io/gallery/3Dwebgl/triangles.html,,triangles}@uref{https://asymptote.sourceforge.io/gallery/3Dwebgl/triangles.asy,,.asy}}.
+
+@cindex @code{thin}
+@cindex @code{thick}
+@cindex @code{tube}
+Arbitrary thick three-dimensional curves and line caps (which the
+@code{OpenGL} standard does not require implementations to provide) are
+constructed with
+@verbatim
+tube tube(path3 p, real width, render render=defaultrender);
+@end verbatim
+@noindent
+this returns a tube structure representing a tube of diameter @code{width}
+centered approximately on @code{g}. The tube structure consists of a
+surface @code{s} and the actual tube center, path3 @code{center}.
+Drawing thick lines as tubes can be slow to render,
+especially with the @code{Adobe Reader} renderer. The setting
+@code{thick=false} can be used to disable this feature and force all
+lines to be drawn with @code{linewidth(0)} (one pixel wide, regardless
+of the resolution). By default, mesh and contour lines in three-dimensions
+are always drawn thin, unless an explicit line width is given in the pen
+parameter or the setting @code{thin} is set to @code{false}. The pens
+@code{thin()} and @code{thick()} defined in @code{plain_pens.asy} can
+also be used to override these defaults for specific draw commands.

+
+Normally, @code{WebGL} files generated by @code{Asymptote} are
+dynamically remeshed to fit the browser window dimensions.
+However, the setting @code{absolute=true} can be used to force the image to be
+rendered at its designed size (accounting for multiple device pixels
+per @code{css} pixel).
+
+The interactive @code{WebGL} files produced by @code{Asymptote} use the
+default mouse and (many of the same) key bindings as the @code{OpenGL}
+renderer. Zooming via the mouse wheel of a @code{WebGL} image embedded
+within another page is disabled until the image is activated by a
+click or touch event and will remain enabled until the @code{ESC} key
+is pressed.
+
+By default, viewing the 3D @acronym{HTML} files generated by Asymptote requires
+network access to download the @code{AsyGL} rendering library, which
+is normally cached by the browser for future use.
+However, the setting @code{offline=true} can be used to embed this
+small (about 48kB) library within a stand-alone @acronym{HTML} file
+that can be viewed offline.

+@code{|n|} for other formats. The default value of @code{render} is -1.
+By default, the scene is internally rendered at twice the specified
+resolution; this can be disabled by setting @code{antialias=1}.
+High resolution rendering is done by tiling the image. If your
+graphics card allows it, the rendering can be made more efficient by
+increasing the maximum tile size @code{maxtile} to your screen
+dimensions (indicated by @code{maxtile=(0,0)}. If your video card
+generates unwanted black stripes in the output, try setting the
+horizontal and vertical components of @code{maxtiles} to something
+less than your screen dimensions. The tile size is also limited by the
+setting @code{maxviewport}, which restricts the maximum width and
+height of the viewport. On @code{UNIX} systems some graphics
+drivers support batch mode (@code{-noV}) rendering in an
+iconified window; this can be enabled with the setting @code{iconify=true}.

+A stationary preview image with a resolution of @code{n} pixels per
+@code{bp} can be embedded with the setting @code{render=n}; this allows

+@code{@uref{https://asymptote.sourceforge.io/gallery/3Dwebgl/three_arrows.html,,three_arrows}@uref{https://asymptote.sourceforge.io/gallery/3Dwebgl/three_arrows.asy,,.asy}} to arbitrary cross sections, colors, and spine
+transformations. The routine
+@verbatim
+surface tube(path3 g, coloredpath section,
+ transform T(real)=new transform(real t) {return identity();},
+ real corner=1, real relstep=0);
+@end verbatim
+@noindent
+draws a tube along @code{g} with cross section @code{section}, after
+applying the transformation @code{T(t)} at @code{point(g,t)}.
+The parameter @code{corner} controls the number of elementary tubes at
+the angular points of @code{g}. A nonzero value of @code{relstep}
+specifies a fixed relative time step (in the sense of
+@code{relpoint(g,t)}) to use in constructing elementary tubes along @code{g}.
+The type @code{coloredpath} is a generalization of @code{path} to
+which a @code{path} can be cast:
+@cindex @code{coloredpath}
+@verbatim
+struct coloredpath
+{
+ path p;
+ pen[] pens(real);
+ int colortype=coloredSegments;
+}
+@end verbatim
+@noindent
+@cindex @code{coloredSegments}
+@cindex @code{coloredNodes}
+Here @code{p} defines the cross section and
+the method @code{pens(real t)} returns an array of pens (interpreted
+as a cyclic array) used for shading the tube patches at
+@code{relpoint(g,t)}. If @code{colortype=coloredSegments}, the tube patches
+are filled as if each segment of the section was colored with the pen
+returned by @code{pens(t)}, whereas if @code{colortype=coloredNodes}, the
+tube components are vertex shaded as if the nodes of the section were colored.
+
+A @code{coloredpath} can be constructed with one of the routines:
+@verbatim
+coloredpath coloredpath(path p, pen[] pens(real),
+ int colortype=coloredSegments);
+coloredpath coloredpath(path p, pen[] pens=new pen[] {currentpen},
+ int colortype=coloredSegments);
+coloredpath coloredpath(path p, pen pen(real));
+@end verbatim
+@noindent
+In the second case, the pens are independent of the relative time.
+In the third case, the array of pens contains only one pen, which
+depends of the relative time.
+
+The casting of @code{path} to @code{coloredpath} allows the
+use of a @code{path} instead of a @code{coloredpath}; in this case the
+shading behaviour is the default shading behavior for a surface.
+
+An example of @code{tube} is provided in the file
+@code{@uref{https://asymptote.sourceforge.io/gallery/3Dwebgl/trefoilknot.html,,trefoilknot}@uref{https://asymptote.sourceforge.io/gallery/3Dwebgl/trefoilknot.asy,,.asy}}. Further examples can be found at

+@end verbatim
+@cindex @code{block.position}
+

+@node contour, contour3, flowchart, Base modules
+@section @code{contour}
+@cindex @code{contour}
+This module draws contour lines.
+To construct contours corresponding to the values in a real array @code{c}
+for a function @code{f} on @code{box(a,b)}, use the routine
+@verbatim
+guide[][] contour(real f(real, real), pair a, pair b,
+ real[] c, int nx=ngraph, int ny=nx,
+ interpolate join=operator --, int subsample=1);
+@end verbatim
+@noindent
+The integers @code{nx} and @code{ny} define the resolution.
+The default resolution, @code{ngraph x ngraph} (here @code{ngraph}
+defaults to @code{100}) can be increased for greater accuracy.
+The default interpolation operator is @code{operator --} (linear). Spline
+interpolation (@code{operator ..}) may produce smoother
+contours but it can also lead to overshooting.
+The @code{subsample} parameter indicates the number of interior points
+that should be used to sample contours within each @code{1 x 1} box;
+the default value of @code{1} is usually sufficient.
+
+To construct contours for an array of data values on a uniform
+two-dimensional lattice on @code{box(a,b)}, use
+@verbatim
+guide[][] contour(real[][] f, pair a, pair b, real[] c,
+ interpolate join=operator --, int subsample=1);
+@end verbatim
+
+To construct contours for an array of data values on a nonoverlapping
+regular mesh specified by the two-dimensional array @code{z},
+@verbatim
+guide[][] contour(pair[][] z, real[][] f, real[] c,
+ interpolate join=operator --, int subsample=1);
+
+@end verbatim
+@noindent
+To construct contours for an array of values @code{f} specified at
+irregularly positioned points @code{z}, use the routine
+@verbatim
+guide[][] contour(pair[] z, real[] f, real[] c, interpolate join=operator --);
+@end verbatim
+@noindent
+The contours themselves can be drawn with one of the routines
+@verbatim
+void draw(picture pic=currentpicture, Label[] L=new Label[],
+ guide[][] g, pen p=currentpen);
+
+void draw(picture pic=currentpicture, Label[] L=new Label[],
+ guide[][] g, pen[] p);
+@end verbatim
+
+The following simple example draws the contour at value @code{1}
+for the function @math{z=x^2+y^2}, which is a unit circle:
+@verbatiminclude onecontour.asy
+@sp 1
+@center @image{./onecontour}
+
+The next example draws and labels multiple contours for the function
+@math{z=x^2-y^2} with the resolution @code{100 x 100}, using a dashed
+pen for negative contours and a solid pen for positive (and zero) contours:
+@verbatiminclude multicontour.asy
+@sp 1
+@center @image{./multicontour}
+
+The next example illustrates how contour lines can be drawn on color
+density images:
+@verbatiminclude imagecontour.asy
+@sp 1
+@center @image{./imagecontour}
+
+Finally, here is an example that illustrates the construction of contours
+from irregularly spaced data:
+@verbatiminclude irregularcontour.asy
+@sp 1
+@center @image{./irregularcontour}
+
+In the above example, the contours of irregularly spaced data are constructed by
+first creating a triangular mesh from an array @code{z} of pairs:
+
+@cindex @code{triangulate}
+@verbatim
+int[][] triangulate(pair[] z);
+@end verbatim
+
+@verbatiminclude triangulate.asy
+@sp 1
+@center @image{./triangulate}
+
+The example @code{@uref{https://asymptote.sourceforge.io/gallery/2Dgraphs/Gouraudcontour.pdf,,Gouraudcontour}@uref{https://asymptote.sourceforge.io/gallery/2Dgraphs/Gouraudcontour.asy,,.asy}} illustrates how to produce color
+density images over such irregular triangular meshes.
+@code{Asymptote} uses a robust version of Paul Bourke's Delaunay triangulation
+algorithm based on the public-domain exact arithmetic predicates written by
+Jonathan Shewchuk.

+Its usage is illustrated in the example file @code{@uref{https://asymptote.sourceforge.io/gallery/3Dgraphs/magnetic.html,,magnetic}@uref{https://asymptote.sourceforge.io/gallery/3Dgraphs/magnetic.asy,,.asy}}.

+@section @code{smoothcontour3}
+@cindex @code{smoothcontour3}
+This module, written by Charles Staats, draws implicitly defined surfaces
+with smooth appearance.
+The purpose of this module is similar to that of @code{contour3}: given
+a real-valued function @math{f(x,y,z)}, construct the surface described by
+the equation @math{f(x,y,z) = 0}. The @code{smoothcontour3} module generally produces
+nicer results than @code{contour3}, but takes longer to compile. Additionally, the
+algorithm assumes that the function and the surface are both smooth; if they are not,
+then @code{contour3} may be a better choice.
+
+To construct the null surface of a function @code{f(triple)} or @code{ff(real,real,real)}
+over @code{box(a,b)}, use the routine
+@cindex @code{implicitsurface}
+@verbatim
+surface implicitsurface(real f(triple)=null,
+ real ff(real,real,real)=null,
+ triple a,
+ triple b,
+ int n=nmesh,
+ bool keyword overlapedges=false,
+ int keyword nx=n,
+ int keyword ny=n,
+ int keyword nz=n,
+ int keyword maxdepth=8,
+ bool usetriangles=true);
+@end verbatim
+@noindent
+The optional parameter @code{overlapedges} attempts to compensate for
+an artifact that can cause the renderer to ``see through'' the
+boundary between patches. Although
+it defaults to @code{false}, it should usually be set to @code{true}.
+The example @code{@uref{https://asymptote.sourceforge.io/gallery/3Dwebgl/genustwo.html,,genustwo}@uref{https://asymptote.sourceforge.io/gallery/3Dwebgl/genustwo.asy,,.asy}} illustrates the use of this function.

+@node slopefield, ode, smoothcontour3, Base modules
+@section @code{slopefield}
+@cindex @code{slopefield}
+To draw a slope field for the differential equation @math{dy/dx=f(x,y)} (or

+@verbatim

+ int nx=nmesh, int ny=nx,
+ real tickfactor=0.5, pen p=currentpen,
+ arrowbar arrow=None);
+@end verbatim
+@noindent
+Here, the points @code{a} and @code{b} are the lower left and upper
+right corners of the rectangle in which the slope field is to be drawn,
+@code{nx} and @code{ny} are the respective number of ticks in the
+@math{x} and @math{y} directions, @code{tickfactor} is the fraction of
+the minimum cell dimension to use for drawing ticks, and @code{p} is
+the pen to use for drawing the slope fields.
+The return value is a picture that can be added to
+@code{currentpicture} via the @code{add(picture)} command.
+
+The function
+@cindex @code{curve}
+@verbatim
+path curve(pair c, real f(real,real), pair a, pair b);
+@end verbatim
+@noindent
+takes a point (@code{c}) and a slope field-defining function @code{f}
+and returns, as a path, the curve passing through that point. The points
+@code{a} and @code{b} represent the rectangular boundaries over which
+the curve is interpolated.
+
+Both @code{slopefield} and @code{curve} alternatively accept a function

+@chapter Interactive mode
+@cindex interactive mode
+Interactive mode is entered by executing the command @code{asy} with
+no file arguments. When the @code{-multiline} option is disabled (the default),
+each line must be a complete @code{Asymptote} statement (unless
+explicitly continued by a final backslash character @code{\});
+it is not necessary to terminate input lines with a semicolon.
+If one assigns @code{settings.multiline=true}, interactive code can be
+entered over multiple lines; in this mode, the automatic termination of
+interactive input lines by a semicolon is inhibited. Multiline mode is useful
+for cutting and pasting @code{Asymptote} code directly into the
+interactive input buffer.
+
+@cindex @code{%}
+Interactive mode can be conveniently used as a calculator: expressions
+entered at the interactive prompt (for which a corresponding @code{write}
+function exists) are automatically evaluated and written to @code{stdout}.
+If the expression is non-writable, its type signature will be printed out
+instead. In either case, the expression can be referred to using the symbol
+@code{%} in the next line input at the prompt. For example:
+@verbatim
+> 2+3
+5
+> %*4
+20
+> 1/%
+0.05
+> sin(%)
+0.0499791692706783
+> currentpicture
+<picture currentpicture>
+> %.size(200,0)
+>
+@end verbatim
+
+@cindex @code{operator answer}
+The @code{%} symbol, when used as a variable, is shorthand for the identifier
+@code{operator answer}, which is set by the prompt after each written
+expression evaluation.
+
+
+The following special commands are supported only in interactive mode
+and must be entered immediately after the prompt:
+
+@table @code
+@cindex @code{help}
+@item help
+view the manual;
+@item erase
+erase @code{currentpicture};
+@cindex @code{input}
+@item reset
+reset the @code{Asymptote} environment to its initial state, except for
+changes to the settings module (@pxref{settings}), the current directory
+(@pxref{cd}), and breakpoints (@pxref{Debugger});
+@cindex @code{input}
+@item input FILE
+does an interactive reset, followed by the command
+@code{include FILE}. If the file name @code{FILE} contains
+nonalphanumeric characters, enclose it with quotation marks.
+A trailing semi-colon followed by optional @code{Asymptote} commands may
+be entered on the same line.
+@cindex @code{quit}
+@cindex @code{exit}
+@cindex @code{history}
+@anchor{history}
+@item quit
+exit interactive mode (@code{exit} is a synonym; the abbreviation
+@code{q} is also accepted unless there exists a top-level variable named
+@code{q}).
+@cindex @code{historylines}
+A history of the most recent 1000 (this number can be changed with the
+@code{historylines} configuration variable) previous commands will be retained
+in the file @code{.asy/history} in the user's home directory (unless
+the command-line option @code{-localhistory} was specified, in which case
+the history will be stored in the file @code{.asy_history} in the
+current directory).
+
+@end table
+
+Typing @code{ctrl-C} interrupts the execution of @code{Asymptote} code
+and returns control to the interactive prompt.
+
+Interactive mode is implemented with the @acronym{GNU} @code{readline} library,
+with command history and auto-completion. To customize the key bindings, see:
+@url{https://tiswww.case.edu/php/chet/readline/readline.html}
+
+@cindex @code{Python} usage
+The file @code{asymptote.py} in the @code{Asymptote} system directory
+provides an alternative way of entering @code{Asymptote} commands
+interactively, coupled with the full power of @code{Python}. Copy this

+@code{Python 3} the commands
+@verbatim

+@cindex GUI installation
+
+As @code{xasy} is written in the interactive scripting language
+@code{Python/Qt}, it requires @code{Python} (@url{https://www.python.org}),
+along with the @code{Python} packages @code{pyqt5}, @code{cson}, and
+@code{numpy}:
+
+@verbatim
+pip3 install cson numpy pyqt5 PyQt5.sip
+@end verbatim
+
+Pictures are deconstructed into the @acronym{SVG} image format.
+Since @code{Qt5} does not support @code{SVG} clipping, you will need
+the @code{rsvg-convert} utility, which is part of the
+@code{librsvg2-tools} package on @code{UNIX} systems
+and the @code{librsvg} package on @code{MacOS X}; under
+@code{Microsoft Windows}, it is available as
+
+@url{https://sourceforge.net/projects/tumagcc/files/rsvg-convert-2.40.20.7z}

+@cindex arrow keys
+@cindex mouse wheel
+@cindex @code{deconstruct}
+The arrow keys (or mouse wheel) are convenient for temporarily
+raising and lowering objects within @code{xasy}, allowing an object to
+be selected. Pressing the arrow keys will pan while the shift key is held
+and zoom while the control key is held. The mouse wheel will pan while
+the alt or shift keys is held and zoom while the control key is held.
+In translate mode, an object can be dragged coarsely with the mouse
+or positioned finely with the arrow keys while holding down the mouse button.
+
+Deconstruction of compound objects (such as arrows) can be prevented
+by enclosing them within the commands
+@verbatim
+void begingroup(picture pic=currentpicture);
+void endgroup(picture pic=currentpicture);
+@end verbatim
+By default, the elements of a picture or frame will be grouped
+together on adding them to a picture. However, the elements of a frame
+added to another frame are not grouped together by default: their
+elements will be individually deconstructed (@pxref{add}).

+@chapter Debugger
+@cindex debugger
+Asymptote now includes a line-based (as opposed to code-based)
+debugger that can assist the user in following flow control. To set a
+break point in file @code{file} at line @code{line}, use the command
+
+@cindex @code{stop}
+@verbatim
+void stop(string file, int line, code s=quote{});
+@end verbatim
+@noindent
+The optional argument @code{s} may be used to conditionally set the variable
+@code{ignore} in @code{plain_debugger.asy} to @code{true}. For example, the
+first 10 instances of this breakpoint will be ignored (the
+variable @code{int count=0} is defined in @code{plain_debugger.asy}):
+@verbatim
+stop("test",2,quote{ignore=(++count <= 10);});
+@end verbatim
+
+To set a break point in file @code{file} at the first line containing
+the string @code{text}, use
+
+@verbatim
+void stop(string file, string text, code s=quote{});
+@end verbatim
+@noindent
+To list all breakpoints, use:
+@cindex @code{breakpoints}
+@verbatim
+void breakpoints();
+@end verbatim
+@noindent
+To clear a breakpoint, use:
+@cindex @code{clear}
+@verbatim
+void clear(string file, int line);
+@end verbatim
+@noindent
+To clear all breakpoints, use:
+@verbatim
+void clear();
+@end verbatim

+The following commands may be entered at the debugging prompt:
+
+@table @code

+ <body>
+ <h1>Asymptote Proposal &mdash External Modules</h1>
+ <h2>Overview</h2>
+ <p>External modules allow users to extend Asymptote by calling functions
+ written in another programming language.</p>
+ <p>Users do this by writing a .asyc file, which contains a mix of
+ Asymptote code and code from another language, say C++. Then, a program
+ is run which produces a .asy file and a C++ source file. The C++ file is
+ compiled to produce a shared library file. Then, the .asy file can be
+ imported in Asymptote to use the externally defined features.</p>
+ <p>This spec is describes a proposed feature that has not yet been
+ implemented. It is incomplete, and does not address all of the issues
+ involved in implementing the feature.</p>
+ <h2>Example</h2>
+ <p>Let&#8217;s look at a simple example that shows off the main features.
+ Asymptote currently doesn&#8217;t offer a way to read the contents of a
+ directory. This would be useful if, say, we wanted to make a series of
+ graphs for every .csv file in a directory.</p>
+ <pre>
+/*****
+ * dir.asyc
+ * Andy Hammerlindl 2007/09/11
+ *
+ * An example for the proposed external module support in Asymptote. This reads
+ * the contents of a directory via the POSIX commands.
+ *
+ * Example usage in asymptote:
+ * access dir;
+ * dir.entry[] entries= dir.open('.');
+ * for (dir.entry e : entries)
+ * write(e.name);
+ *****/
+
+// Verbatim code will appear in the c++ or asy file (as specified) interleaved
+// in the same order as it appears here.
+verbatim c++ {
+ #include &lt;sys/types.h&gt;
+ #include &lt;dirent.h&gt;
+ #include &lt;errno.h&gt;
+
+ // asy.h is included by default (needed for hidden code, anyway).
+ // Asymptote-specific types, such as array below, are in the asy namespace.
+ using namespace asy;
+}
+
+// Define a new opaque type in asy which is internally represented by struct
+// dirent *. This is too messy to expose to users of the module, so define
+// everything as private.

+ return (Int)e-&gt;d_ino;
+}
+

+
+// Define an asy structure to expose the information. These steps are annoying,

+ reclen=entry_d_reclen(e);
+ type=entry_d_type(e);
+ name=entry_d_name(e);
+ }
+ }
+}
+
+
+// Given the name of a directory, return an array of entries. Return 0
+// (a null array) on error.
+private entry_t[] base_read(string name)
+{
+ DIR *dir=opendir(name.c_str());
+
+ // TODO: Add standard style of error reporting.
+ if (dir == NULL)
+ return 0;
+
+ // Create the array structure.
+ // array is derived from gc, so will be automatically memory-managed.
+ array *a=new array();
+
+ struct dirent *entry;
+ while (entry=readdir(dir))
+ a-&gt;push&lt;struct dirent *&gt;(entry);
+
+ // The loop has exited, either by error, or after reading the entire
+ // directory. Check before closedir(), in case that call resets errno.
+ if (errno != 0) {
+ closedir(dir);
+ return 0;
+ }
+
+ closedir(dir);
+ return a;
+}
+
+verbatim asy {
+ private entry[] cleanEntries(entry_t[] raw_entries) {
+ if (raw_entries) {

+ return entries;
+ }
+ return null;
+ }
+
+ entry[] read(string name) {
+ return cleanEntries(base_read(name));
+ }
+}
+
+</pre>
+ <h2>Type Mappings</h2>
+ <p>Types in Asymptote do not directly relate to types in C++, but there
+ is a partial mapping between them. The header file
+ <code>asymptote.h</code> provides typedefs for the primitive asymptote
+ types. For instance <code>string</code> in Asymptote maps to the C++
+ class <code>asy::string</code> which is a variant of
+ <code>std::string</code> and <code>real</code> to <code>asy::real</code>
+ which is a basic floating point type (probably <code>double</code>).
+ Because <code>int</code> is a reserved word in C++, the Asymptote type
+ <code>int</code> is mapped to <code>asy::Int</code> which is one of the
+ basic signed numeric types in C++ (currently 64 bit).
+ <code>asy::pair</code> is a class that implements complex numbers. In
+ the first version of the external module implementation, these will be
+ the only primitive types with mappings, but eventually all of them will
+ be added.</p>
+
+ <p>All Asymptote arrays, regardless of the cell type, are mapped to
+ <code>asy::array *</code> where <code>asy::array</code> is a C++ class.
+ The cells of the array are of the type <code>asy::item</code> which can
+ hold any Asymptote data type. Items can be constructed from any C++
+ type. Once constructed, the value of an item can be retrieved by the
+ function <code>template&lt;typename T&gt; T get(const item&amp;)</code>.
+ Calling <code>get</code> on an item using the wrong type generates a
+ runtime error. </p>
+<pre>
+// Examples of using item.
+item x((asy::Int)2);
+item y(3.4);
+item z=new array;
+item w=(asy::real)3.4;
+
+cout &lt;&lt; get&lt;asy::Int&gt;(x);
+cout &lt;&lt; get&lt;double&gt;(y);
+
+x=y; // x now stores a double.
+cout &lt;&lt; get&lt;double&gt;(x);
+
+cout &lt;&lt; get&lt;asy::real&gt;(w);
+</pre>
+
+ <p>The <code>asy::array</code> class implements, at a minimum, the
+ methods:</p>
+ <ul>
+ <li><code>size_t size()</code>
+ which returns the number of elements,</li>
+ <li><code>template &lt;typename T&gt; T read(size_t i) const</code>
+ which returns the i-th element, interpreted as being of type t.</li>
+ <li><code>template &lt;typename T&gt; void push(item i)</code>
+ adds the item to the end of the array.</li>
+ </ul>
+ <p>It allows access to elements of the array as items by
+ <code>operator[]</code>. We may specify that <code>asy::array</code>
+ be a model of the Random Access Container in the C++ Standard Template
+ Library. It is currently implemented as a subclass of an STL
+ vector.</p>
+<pre>
+// Example of a C++ function that doubles the entries in an array of integers.
+using namespace asy;
+
+void doubler(array *a) {
+ assert(a);
+ size_t length=a-&gt;size();
+ for (size_t i=0; i&lt;length; ++i) {
+ Int x=a-&gt;read&lt;Int&gt;(i); // This is shorthand for get&lt;Int&gt;((*a)[i]).
+ a[i]=2*x; // The type of 2*x is also Int, so this will enter
+ // the item as the proper type.
+ }
+}
+</pre>
+ <p>Users can map new Asymptote types to their own custom C++ types using
+ Opaque Type Declarations, explained below.</p>
+
+ <h2>Syntactic Features</h2>
+ <p>A .asyc file is neither an asy file with some C++ in it, nor a C++
+ with some asy code in it. It can only contain a small number of
+ specific constructs:</p>
+ <ul>
+ <li>Comments</li>
+ <li>Function Definitions</li>
+ <li>Verbatim Code Block</li>
+ <li>Opaque Type Declaration</li>
+ </ul>
+ <!-- Move to after constructs -->
+ <p>Each component may produce code for either the .asy file, the .cc
+ file, or both. The pieces of code produced by each construct appears in
+ the output file in the same order as the constructs in the .asyc. For
+ example, if a function definition occurs before a verbatim Asymptote
+ code block, we can be sure that the function is defined and can be used
+ in that block. Similarly, if a verbatim C++ block occurs before a
+ function definition, then the body of the function can use features
+ declared in the verbatim section.</p>
+
+ <h3>Comments</h3>
+ <p>C++/Asymptote style comments using <code>/* */</code> or
+ <code>//</code> are allowed at the top level. These do not affect the
+ definition of the module, but the implementation may copy them into the
+ .asy and .cc to help explain the resulting code.</p>
+
+ <h3>Verbatim Code Blocks</h3>
+ <p>Verbatim code, ie. code to be copied directly into the either
+ the output .asy or .cc file can be specified in the .asyc file by
+ enclosing it in a verbatim code block. This starts with the special
+ identifier <code>verbatim</code> followed by either <code>c++</code>
+ or <code>asy</code> to specify into which file the code will be copied,
+ and then a block of code in braces. When the .asyc file is parsed,
+ the parser keeps track of matching open and close braces inside the
+ verbatim code block, so that the brace at the start of the block can
+ be matched with the one at the end. This matching process will ignore
+ braces occuring in comments and string and character literals.</p>
+ <h4>Open issue</h4>
+ <p>It may prove to be impractical to walk through the code, matching
+ braces. Also, this plan precludes having a verbatim block with an
+ unbalanced number of braces which might be useful, say to start a
+ namespace at the beginning of the C++ file, and end it at the end of the
+ file. As such, it may be useful to have another technique. A really
+ simple idea (with obvious drawbacks) would be to use the first closing
+ braces that occur at the same indentation level as the verbatim keyword
+ (assuming that the code block itself will be indented). Other
+ alternatives are to use more complicated tokens such as <code>%{</code>
+ and <code>%}</code>, or the shell style <code>&lt;&lt;EOF</code>.</p>
+
+ <h3>Function Definitions</h3>
+ <p>A function definition given at the top level of the file (and not
+ inside a verbatim block) looks much like a function definition in
+ Asymptote or C++, but is actually a mix of both. The header of the
+ function is given in Asymptote code, and defines how the function will
+ look in the resulting Asymptote module. The body, on the other hand, is
+ given in C++, and defines how the function is implemented in C++. As a
+ simple example, consider:
+ <pre>real sum(real x, real y=0.0) {
+ return x+y;
+}</pre>
+ <h4>Header</h4>
+ <p> The header of the definition gives
+ the name, permission, return type, and parameters of the function.
+ Because the function is defined for use in Asymptote, all of the types
+ are given as Asymptote types.</p>
+ <h5>Permissions</h5>
+ <p>As in pure Asymptote, the function can optionally be given a
+ <code>private</code>, <code>restricted</code> or <code>public</code>
+ permission. If not specified, the permission is <code>public</code> by
+ default. This is the permission that the function will have when it is
+ part of the Asymptote module. The example of <code>sum</code> above
+ specifies no permission, so it is public.</p>
+ <p>Just as public methods such as <code>plain.draw</code> can be
+ re-assigned by scripts that import the <code>plain</code> module, the
+ current plan is to allow Asymptote code to modify public members of any
+ module, including ones defined using native code. This is in contrast
+ to builtin functions bindings, which cannot be modified.</p>
+ <h5>Return Type</h5>
+ <p>This gives the Asymptote return type of the function. This cannot be
+ an arbitrary Asymptote type, but must one which maps to a C++ type as
+ explained in the type mapping section above. Our example of <code>sum</code> gives
+ <code>real</code> as a return type, which maps to the C++ type
+ <code>asy::real</code>.</p>
+ <h5>Function Name</h5>
+ <p>This gives the name of the function as it will appear in the
+ Asymptote module. In our example, the Asymptote name is
+ <code>sum</code>. The name can be any Asymptote identifier, including
+ operator names, such as <code>operator +</code>.</p>
+ <p>It is important to note that the Asymptote name has no relation to
+ the C++ name of the function, which may be something strange, such as
+ <code>_asy_func_modulename162</code>. Also, the actual signature and
+ return type of the C++ function may bear no relation to the Asymptote
+ signature. That said, the C++ name of the function may be defined by
+ giving the function name as <code>asyname:cname</code>. Then it can be
+ referred to by other C++ code. The function will be defined with C
+ calling convention, so that its name is not mangled.</p>
+ <h5>Formal Parameters</h5>
+ <p>The function header takes a list of formal parameters. Just as in
+ pure Asymptote code, these can include <code>explicit</code>
+ keywords, type declarations with array and functional types, and rest
+ parameters. Just as with the return type of the function, the type of
+ each of the parameters must map to a C++ type.</p>
+ <p>Parameters may be given an optional Asymptote name and an optional
+ C++ name. These may be declared in one of six ways as in the following
+ examples:</p>
+ <pre>void f(int)
+void f(int name)
+void f(int :)
+void f(int asyname:)
+void f(int :cname)
+void f(int asyname:cname)
+</pre>
+ <p>If the parameter just contains a type, with no identifier,
+ then it has no Asymptote name and no C++ name. If it contains a single
+ name (with no colon), then that name is both the Asymptote and the C++
+ name. If it contains a colon in the place of an identifier, with an
+ optional name in front of the colon and an optional name behind the
+ colon, than the name in front (if given) is the Asymptote name, and the
+ name behind (if given) is the C++ name.</p>
+ <p>The Asymptote name can be any Asymptote identifier, including
+ operator names, but the C++ name must be a valid C++ identifier. For
+ instance <code>void f(int operator +)</code> is not allowed, as the
+ parameter would not have a valid C++ name. The examples
+ <code>void f(int operator +:)</code> and
+ <code>void f(int operator +:addop)</code> are allowed.</p>
+ <p>When called by Asymptote code, named arguments are only matched to
+ the Asymptote names, so for example a function defined by
+ <code>void f(int :x, string x:y)</code> could be called by
+ <code>f(x="hi mom", 4)</code>, but one defined by
+ <code>void f(int x, string x:y)</code> could not.</p>
+ <p>Each formal parameter may take a piece of code as a default value.
+ Because the function is implemented in C++, this code must be given as
+ C++ code. More akin to Asymptote than C++, default arguments may occur
+ for any non-rest parameters, not just those at the end of the list, and
+ may refer to earlier parameters in the list. Earlier parameters are
+ refered to by their C++ names. Example:
+<pre>void drawbox(pair center, real width, real height=2*width, pen p)</pre>
+ Default arguments are parsed by finding the next comma that is not part
+ of a comment, string literal, or character constant, and is not nested
+ inside parentheses. The C++ code between the equals-sign and the comma
+ is taken as the expression for the default argument.</p>
+ <h4>Body</h4>
+ <p>The body of the function is written as C++ code. When the .asyc
+ file is processed, this C++ code is copied verbatim into an actual C++
+ function providing the implementation. However, the actual body of the
+ resultant C++ function may contain code other than the body provided by
+ the user. This auxillary code could include instruction to retrieve the
+ arguments of the function from their representation in the Asymptote
+ virtual machine and bind them to local variables with their C++ names.
+ It could also include initialization and finalization code for the
+ function.</p>
+ <p>In writing code for the function body, one can be assured that all
+ function arguments with C++ names have been bound and are therefore
+ usable in the code. Since all parameters must have Asymptote types that
+ map to C++ types, the types of the paramaters in the body have the type
+ resulting from that mapping.</p>
+ <p>The <code>return</code> keyword can be used to return the result of
+ the function (or without an expression, if the return type was declared
+ as void). The Asymptote return type must map to a C++ type, and the
+ expression given in the return statement will be implicitly cast to that
+ type.</p>
+ <p>Since the implementation will likely not use an actual return
+ statement to return the value of the function back to the Asymptote
+ virtual machine, the interpreter of the .asyc file may walk through the
+ code converting return expressions into a special format in the actual
+ implementation of the function.<p>
+
+ <h3>Opaque Type Declarations</h3>
+ <p>There are a number of mappings between Asymptote and C++ types
+ builtin to the facility. For instance <code>int</code> maps to
+ <code>asy::Int</code> and <code>real</code> to <code>asy::real</code>.
+ Users, however, may want to reference other C++ objects in Asymptote
+ code. This done though opaque type declarations.</p>
+
+ <p>An opaque type declaration is given by an optional permission
+ modifier, the keyword <code>asytype</code>, a C++ type, and an Asymptote
+ identifier; in that order.</p>
+<pre>
+// Examples
+asytype char char;
+public asytype const std::list&lt;asy::Int&gt; *intList;
+private asytype const struct dirert *entry_t;
+</pre>
+ <p>This declaration mapping the Asymptote identifier to the C++ type
+ within the module. The permission of the Asymptote type is given by the
+ permission modifier (or public if the modifier is omitted). The type is
+ opaque, in that none of its internal structure is revealed in the
+ Asymptote code. Like any other type, however, objects of this new type
+ can be returned from functions, given as an arguments to functions, and
+ stored in variables, structures and arrays.</p>
+ <p>In many cases, such as the directory listing example at the start, it
+ will be practical to declare the type as private, and use an Asymptote
+ structure as a wrapper hiding the C++ implementation.</p>

+1 Description
+*************
+
+'Asymptote' is a powerful descriptive vector graphics language that
+provides a mathematical coordinate-based framework for technical
+drawing. Labels and equations are typeset with 'LaTeX', for overall
+document consistency, yielding the same high-quality level of
+typesetting that 'LaTeX' provides for scientific text. By default it
+produces 'PostScript' output, but it can also generate 'PDF', 'SVG',
+'WebGL', 'PRC', and any format that the 'ImageMagick' package can
+produce. You can even try it out in your Web browser without installing
+it, using the 'Asymptote Web Application':
+
+ <http://asymptote.ualberta.ca>
+
+ A major advantage of 'Asymptote' over other graphics packages is that
+it is a high-level programming language, as opposed to just a graphics
+program: it can therefore exploit the best features of the script
+(command-driven) and graphical-user-interface (GUI) methods for
+producing figures. The rudimentary GUI 'xasy' included with the package
+allows one to move script-generated objects around. To make 'Asymptote'
+accessible to the average user, this GUI is currently being developed
+into a full-fledged interface that can generate objects directly.
+However, the script portion of the language is now ready for general use
+by users who are willing to learn a few simple 'Asymptote' graphics
+commands (*note Drawing commands::).
+
+ 'Asymptote' is mathematically oriented (e.g. one can use complex
+multiplication to rotate a vector) and uses 'LaTeX' to do the
+typesetting of labels. This is an important feature for scientific
+applications. It was inspired by an earlier drawing program (with a
+weaker syntax and capabilities) called 'MetaPost'.
+
+ The 'Asymptote' vector graphics language provides:
+
+ * a standard for typesetting mathematical figures, just as
+ TeX/'LaTeX' is the de-facto standard for typesetting equations.
+
+ * 'LaTeX' typesetting of labels, for overall document consistency;
+
+ * the ability to generate and embed 3D vector WebGL graphics within
+ HTML files;
+
+ * the ability to generate and embed 3D vector PRC graphics within PDF
+ files;
+
+ * a natural coordinate-based framework for technical drawing,
+ inspired by 'MetaPost', with a much cleaner, powerful C++-like
+ programming syntax;
+
+ * compilation of figures into virtual machine code for speed, without
+ sacrificing portability;
+
+ * the power of a script-based language coupled to the convenience of
+ a GUI;
+
+ * customization using its own C++-like graphics programming language;
+
+ * sensible defaults for graphical features, with the ability to
+ override;
+
+ * a high-level mathematically oriented interface to the 'PostScript'
+ language for vector graphics, including affine transforms and
+ complex variables;
+
+ * functions that can create new (anonymous) functions;
+
+ * deferred drawing that uses the simplex method to solve overall size
+ constraint issues between fixed-sized objects (labels and
+ arrowheads) and objects that should scale with figure size;
+
+ Many of the features of 'Asymptote' are written in the 'Asymptote'
+language itself. While the stock version of 'Asymptote' is designed for
+mathematics typesetting needs, one can write 'Asymptote' modules that
+tailor it to specific applications; for example, a scientific graphing
+module is available (*note graph::). Examples of 'Asymptote' code and
+output, including animations, are available at
+ <https://asymptote.sourceforge.io/gallery/>
+Clicking on an example file name in this manual, like 'Pythagoras', will
+display the PDF output, whereas clicking on its '.asy' extension will
+show the corresponding 'Asymptote' code in a separate window.
+
+ Links to many external resources, including an excellent user-written
+'Asymptote' tutorial can be found at
+ <https://asymptote.sourceforge.io/links.html>
+ A quick reference card for 'Asymptote' is available at
+ <https://asymptote.sourceforge.io/asyRefCard.pdf>

+
+2.1 UNIX binary distributions
+=============================
+
+We release both 'tgz' and RPM binary distributions of 'Asymptote'. The
+root user can install the 'Linux x86_64' 'tgz' distribution of version
+'x.xx' of 'Asymptote' with the commands:
+tar -C / -zxf asymptote-x.xx.x86_64.tgz
+texhash
+The 'texhash' command, which installs LaTeX style files, is optional.
+The executable file will be '/usr/local/bin/asy') and example code will
+be installed by default in '/usr/local/share/doc/asymptote/examples'.
+
+Fedora users can easily install a recent version of 'Asymptote' with the
+command
+dnf --enablerepo=rawhide install asymptote
+
+To install the latest version of 'Asymptote' on a Debian-based
+distribution (e.g. Ubuntu, Mepis, Linspire) follow the instructions for
+compiling from 'UNIX' source (*note Compiling from UNIX source::).
+Alternatively, Debian users can install one of Hubert Chan's prebuilt
+'Asymptote' binaries from
+ <http://ftp.debian.org/debian/pool/main/a/asymptote>
+
+
+File: asymptote.info, Node: MacOS X binary distributions, Next: Microsoft Windows, Prev: UNIX binary distributions, Up: Installation
+
+2.2 MacOS X binary distributions
+================================
+
+'MacOS X' users can either compile the 'UNIX' source code (*note
+Compiling from UNIX source::) or install the 'Asymptote' binary
+available at
+
+ <https://www.macports.org/>
+
+Note that many 'MacOS X' (and FreeBSD) systems lack the GNU 'readline'
+library. For full interactive functionality, GNU 'readline' version 4.3
+or later must be installed.
+
+
+File: asymptote.info, Node: Microsoft Windows, Next: Configuring, Prev: MacOS X binary distributions, Up: Installation
+
+2.3 Microsoft Windows
+=====================
+
+Users of the 'Microsoft Windows' operating system can install the
+self-extracting 'Asymptote' executable 'asymptote-x.xx-setup.exe', where
+'x.xx' denotes the latest version.
+
+ A working TeX implementation (we recommend
+<https://www.tug.org/texlive> or <http://www.miktex.org>) will be
+required to typeset labels. You will also need to install 'GPL
+Ghostscript' version 9.52 or later from
+<http://downloads.ghostscript.com/public>.
+
+ To view 'PostScript' output, you can install the program 'gsview'
+available from <http://www.cs.wisc.edu/~ghost/gsview/>.
+
+ The 'ImageMagick' package from
+<https://www.imagemagick.org/script/binary-releases.php>
+
+is required to support output formats other than HTML, PDF, SVG, and PNG
+(*note convert::). The 'Python 3' interpreter from
+<https://www.python.org> is only required if you wish to try out the
+graphical user interface (*note GUI::).
+
+Example code will be installed by default in the 'examples' subdirectory
+of the installation directory (by default, 'C:\Program
+Files\Asymptote').
+
+
+File: asymptote.info, Node: Configuring, Next: Search paths, Prev: Microsoft Windows, Up: Installation
+
+2.4 Configuring
+===============
+
+In interactive mode, or when given the '-V' option (the default when
+running 'Asymptote' on a single file under 'MSDOS'), 'Asymptote' will
+automatically invoke the 'PostScript' viewer 'gv' (under 'UNIX') or
+'gsview' (under 'MSDOS' to display graphical output. The 'PostScript'
+viewer should be capable of automatically redrawing whenever the output
+file is updated. The default 'UNIX' 'PostScript' viewer 'gv' supports
+this (via a 'SIGHUP' signal). Version 'gv-3.6.3' or later (from
+<https://ftp.gnu.org/gnu/gv/>) is required for interactive mode to work
+properly. Users of 'ggv' will need to enable 'Watch file' under
+'Edit/PostScript Viewer Preferences'. Users of 'gsview' will need to
+enable 'Options/Auto Redisplay' (however, under 'MSDOS' it is still
+necessary to click on the 'gsview' window; under 'UNIX' one must
+manually redisplay by pressing the 'r' key).
+
+ Configuration variables are most easily set as 'Asymptote' variables
+in an optional configuration file 'config.asy' *note configuration
+file::). For example, the setting 'pdfviewer' specifies the location of
+the PDF viewer. Here are the default values of several important
+configuration variables under 'UNIX':
+
+import settings;
+pdfviewer="acroread";
+htmlviewer="google-chrome";
+psviewer="gv";
+display="display";
+animate="animate";
+gs="gs";
+libgs="";
+
+Under 'MSDOS', the viewer settings 'htmlviewer', 'pdfviewer',
+'psviewer', 'display', and 'animate' default to the string 'cmd',
+requesting the application normally associated with each file type. The
+(installation-dependent) default values of 'gs' and 'libgs' are
+determined automatically from the 'Microsoft Windows' registry. The
+'gs' setting specifies the location of the 'PostScript' processor
+'Ghostscript', available from <https://www.ghostscript.com/>.
+
+The configuration variable 'htmlviewer' specifies the browser to use to
+display 3D 'WebGL' output. The default setting is 'google-chrome' under
+'UNIX' and 'cmd' under 'Microsoft Windows'. Note that 'Internet
+Explorer' does not support 'WebGL'; 'Microsoft Windows' users should set
+their default html browser to 'chrome' or 'microsoft-edge'. By default,
+2D and 3D 'HTML' images expand to the enclosing canvas; this can be
+disabled by setting the configuation variable 'absolute' to 'true'.
+
+ On 'UNIX' systems, to support automatic document reloading of 'PDF'
+files in 'Adobe Reader', we recommend copying the file 'reload.js' from
+the 'Asymptote' system directory (by default,
+'/usr/local/share/asymptote' under 'UNIX' to
+'~/.adobe/Acrobat/x.x/JavaScripts/', where 'x.x' represents the
+appropriate 'Adobe Reader' version number. The automatic document
+reload feature must then be explicitly enabled by putting
+import settings;
+pdfreload=true;
+pdfreloadOptions="-tempFile";
+in the 'Asymptote' configuration file. This reload feature is not
+useful under 'MSDOS' since the document cannot be updated anyway on that
+operating system until it is first closed by 'Adobe Reader'.
+
+ The configuration variable 'dir' can be used to adjust the search
+path (*note Search paths::).
+
+ By default, 'Asymptote' attempts to center the figure on the page,
+assuming that the paper type is 'letter'. The default paper type may be
+changed to 'a4' with the configuration variable 'papertype'. Alignment
+to other paper sizes can be obtained by setting the configuration
+variables 'paperwidth' and 'paperheight'.
+
+ These additional configuration variables normally do not require
+adjustment:
+config
+texpath
+texcommand
+dvips
+dvisvgm
+convert
+asygl
+
+ Warnings (such as "unbounded" and "offaxis") may be enabled or
+disabled with the functions
+warn(string s);
+nowarn(string s);
+or by directly modifying the string array 'settings.suppress', which
+lists all disabled warnings.
+
+ Configuration variables may also be set or overwritten with a
+command-line option:
+asy -psviewer=gsview -V venn
+
+ Alternatively, system environment versions of the above configuration
+variables may be set in the conventional way. The corresponding
+environment variable name is obtained by converting the configuration
+variable name to upper case and prepending 'ASYMPTOTE_': for example, to
+set the environment variable
+ASYMPTOTE_PSVIEWER="C:\Program Files\Ghostgum\gsview\gsview32.exe";
+under 'Microsoft Windows XP':
+ 1. Click on the 'Start' button;
+ 2. Right-click on 'My Computer';
+ 3. Choose 'View system information';
+ 4. Click the 'Advanced' tab;
+ 5. Click the 'Environment Variables' button.
+
+
+File: asymptote.info, Node: Search paths, Next: Compiling from UNIX source, Prev: Configuring, Up: Installation
+
+2.5 Search paths
+================
+
+In looking for 'Asymptote' files, 'asy' will search the following paths,
+in the order listed:
+ 1. The current directory;
+ 2. A list of one or more directories specified by the configuration
+ variable 'dir' or environment variable 'ASYMPTOTE_DIR' (separated
+ by ':' under UNIX and ';' under 'MSDOS');
+ 3. The directory specified by the environment variable
+ 'ASYMPTOTE_HOME'; if this variable is not set, the directory '.asy'
+ in the user's home directory ('%USERPROFILE%\.asy' under 'MSDOS')
+ is used;
+ 4. The 'Asymptote' system directory (by default,
+ '/usr/local/share/asymptote' under 'UNIX' and 'C:\Program
+ Files\Asymptote' under 'MSDOS').
+ 5. The 'Asymptote' examples directory (by default,
+ '/usr/local/share/doc/asymptote/examples' under 'UNIX' and
+ 'C:\Program Files\Asymptote\examples' under 'MSDOS').

+==============================
+
+To compile and install a 'UNIX' executable from the source release
+'asymptote-x.xx.src.tgz' in the subdirectory 'x.xx' under
+
+ <https://sourceforge.net/projects/asymptote/files/>
+
+ execute the commands:
+gunzip asymptote-x.xx.src.tgz
+tar -xf asymptote-x.xx.src.tar
+cd asymptote-x.xx
+ By default the system version of the Boehm garbage collector will be
+used; if it is old we recommend first putting
+<https://github.com/ivmai/bdwgc/releases/download/v8.0.4/gc-8.0.4.tar.gz>
+<https://www.ivmaisoft.com/_bin/atomic_ops/libatomic_ops-7.6.10.tar.gz>
+in the 'Asymptote' source directory.
+
+ On 'UNIX' platforms (other than 'MacOS X'), we recommend using
+version '3.2.1' of the 'freeglut' library. To compile 'freeglut',
+download
+ <https://prdownloads.sourceforge.net/freeglut/freeglut-3.2.1.tar.gz>
+and type (as the root user):
+gunzip freeglut-3.2.1.tar.gz
+tar -xf freeglut-3.2.1.tar
+cd freeglut-3.2.1
+cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_C_FLAGS=-fcommon .
+make
+make install
+
+ Then compile 'Asymptote' with the commands
+./configure
+make all
+make install
+Be sure to use GNU 'make' (on non-GNU systems this command may be called
+'gmake'). To build the documentation, you may need to install the
+'texinfo-tex' package. If you get errors from a broken 'texinfo' or
+'pdftex' installation, simply put
+ <https://asymptote.sourceforge.io/asymptote.pdf>
+in the directory 'doc' and repeat the command 'make all'.
+
+For a (default) system-wide installation, the last command should be
+done as the root user. To install without root privileges, change the
+'./configure' command to
+./configure --prefix=$HOME/asymptote
+ One can disable use of the Boehm garbage collector by configuring
+with './configure --disable-gc'. For a list of other configuration
+options, say './configure --help'. For example, under 'MacOS X', one
+can tell configure to use the 'clang' compilers and look for header
+files and libraries in nonstandard locations:
+./configure CC=clang CXX=clang++ CPPFLAGS=-I/opt/local/include LDFLAGS=-L/opt/local/lib
+
+ If you are compiling 'Asymptote' with 'gcc', you will need a
+relatively recent version (e.g. 3.4.4 or later). For full interactive
+functionality, you will need version 4.3 or later of the GNU 'readline'
+library. The file 'gcc3.3.2curses.patch' in the 'patches' directory can
+be used to patch the broken curses.h header file (or a local copy
+thereof in the current directory) on some 'AIX' and 'IRIX' systems.
+
+ The 'FFTW' library is only required if you want 'Asymptote' to be
+able to take Fourier transforms of data (say, to compute an audio power
+spectrum). The 'GSL' library is only required if you require the
+special functions that it supports.
+
+ If you don't want to install 'Asymptote' system wide, just make sure
+the compiled binary 'asy' and GUI script 'xasy' are in your path and set
+the configuration variable 'dir' to point to the directory 'base' (in
+the top level directory of the 'Asymptote' source code).

+
+2.7 Editing modes
+=================
+
+Users of 'emacs' can edit 'Asymptote' code with the mode 'asy-mode',
+after enabling it by putting the following lines in their '.emacs'
+initialization file, replacing 'ASYDIR' with the location of the
+'Asymptote' system directory (by default, '/usr/local/share/asymptote'
+or 'C:\Program Files\Asymptote' under 'MSDOS'):
+(add-to-list 'load-path "ASYDIR")
+(autoload 'asy-mode "asy-mode.el" "Asymptote major mode." t)
+(autoload 'lasy-mode "asy-mode.el" "hybrid Asymptote/Latex major mode." t)
+(autoload 'asy-insinuate-latex "asy-mode.el" "Asymptote insinuate LaTeX." t)
+(add-to-list 'auto-mode-alist '("\\.asy$" . asy-mode))
+
+Particularly useful key bindings in this mode are 'C-c C-c', which
+compiles and displays the current buffer, and the key binding 'C-c ?',
+which shows the available function prototypes for the command at the
+cursor. For full functionality you should also install the Apache
+Software Foundation package 'two-mode-mode':
+ <https://www.dedasys.com/freesoftware/files/two-mode-mode.el>
+Once installed, you can use the hybrid mode 'lasy-mode' to edit a LaTeX
+file containing embedded 'Asymptote' code (*note LaTeX usage::). This
+mode can be enabled within 'latex-mode' with the key sequence 'M-x
+lasy-mode <RET>'. On 'UNIX' systems, additional keywords will be
+generated from all 'asy' files in the space-separated list of
+directories specified by the environment variable 'ASYMPTOTE_SITEDIR'.
+Further documentation of 'asy-mode' is available within 'emacs' by
+pressing the sequence keys 'C-h f asy-mode <RET>'.
+
+ Fans of 'vim' can customize 'vim' for 'Asymptote' with
+
+'cp /usr/local/share/asymptote/asy.vim ~/.vim/syntax/asy.vim'
+
+and add the following to their '~/.vimrc' file:
+augroup filetypedetect
+au BufNewFile,BufRead *.asy setf asy
+augroup END
+filetype plugin on
+
+ If any of these directories or files don't exist, just create them.
+To set 'vim' up to run the current asymptote script using ':make' just
+add to '~/.vim/ftplugin/asy.vim':
+setlocal makeprg=asy\ %
+setlocal errorformat=%f:\ %l.%c:\ %m
+
+ Syntax highlighting support for the KDE editor 'Kate' can be enabled
+by running 'asy-kate.sh' in the '/usr/local/share/asymptote' directory
+and putting the generated 'asymptote.xml' file in
+'~/.kde/share/apps/katepart/syntax/'.

+
+
+File: asymptote.info, Node: Drawing in batch mode, Next: Drawing in interactive mode, Prev: Tutorial, Up: Tutorial
+
+3.1 Drawing in batch mode
+=========================
+
+To draw a line from coordinate (0,0) to coordinate (100,100), create a
+text file 'test.asy' containing
+draw((0,0)--(100,100));
+
+Then execute the command
+asy -V test
+Alternatively, 'MSDOS' users can drag and drop 'test.asy' onto the
+Desktop 'asy' icon (or make 'Asymptote' the default application for the
+extension 'asy').
+
+This method, known as _batch mode_, outputs a 'PostScript' file
+'test.eps'. If you prefer PDF output, use the command line
+asy -V -f pdf test
+ In either case, the '-V' option opens up a viewer window so you can
+immediately view the result:
+
+ [./diagonal]
+Here, the '--' connector joins the two points '(0,0)' and '(100,100)'
+with a line segment.
+
+
+File: asymptote.info, Node: Drawing in interactive mode, Next: Figure size, Prev: Drawing in batch mode, Up: Tutorial
+
+3.2 Drawing in interactive mode
+===============================
+
+Another method is _interactive mode_, where 'Asymptote' reads individual
+commands as they are entered by the user. To try this out, enter
+'Asymptote''s interactive mode by clicking on the 'Asymptote' icon or
+typing the command 'asy'. Then type
+draw((0,0)--(100,100));
+followed by 'Enter', to obtain the above image. At this point you can
+type further 'draw' commands, which will be added to the displayed
+figure, 'erase' to clear the canvas,
+input test;
+to execute all of the commands contained in the file 'test.asy', or
+'quit' to exit interactive mode. You can use the arrow keys in
+interactive mode to edit previous lines. The tab key will automatically
+complete unambiguous words; otherwise, hitting tab again will show the
+possible choices. Further commands specific to interactive mode are
+described in *note Interactive mode::.
+
+
+File: asymptote.info, Node: Figure size, Next: Labels, Prev: Drawing in interactive mode, Up: Tutorial
+
+3.3 Figure size
+===============
+
+In 'Asymptote', coordinates like '(0,0)' and '(100,100)', called
+_pairs_, are expressed in 'PostScript' "big points" (1 'bp' = 1/72
+'inch') and the default line width is '0.5bp'. However, it is often
+inconvenient to work directly in 'PostScript' coordinates. The next
+example produces identical output to the previous example, by scaling
+the line '(0,0)--(1,1)' to fit a rectangle of width '100.5 bp' and
+height '100.5 bp' (the extra '0.5bp' accounts for the line width):
+size(100.5,100.5);
+draw((0,0)--(1,1));
+
+ [./diagonal]
+
+ One can also specify the size in 'pt' (1 'pt' = 1/72.27 'inch'),
+'cm', 'mm', or 'inches'. Two nonzero size arguments (or a single size
+argument) restrict the size in both directions, preserving the aspect
+ratio. If 0 is given as a size argument, no restriction is made in that
+direction; the overall scaling will be determined by the other direction
+(*note size::):
+size(0,100.5);
+draw((0,0)--(2,1),Arrow);
+
+ [./bigdiagonal]
+
+ To connect several points and create a cyclic path, use the 'cycle'
+keyword:
+size(3cm);
+draw((0,0)--(1,0)--(1,1)--(0,1)--cycle);
+
+ [./square]
+For convenience, the path '(0,0)--(1,0)--(1,1)--(0,1)--cycle' may be
+replaced with the predefined variable 'unitsquare', or equivalently,
+'box((0,0),(1,1))'.
+
+ To make the user coordinates represent multiples of exactly '1cm':
+unitsize(1cm);
+draw(unitsquare);
+
+
+File: asymptote.info, Node: Labels, Next: Paths, Prev: Figure size, Up: Tutorial
+
+3.4 Labels
+==========
+
+Adding labels is easy in 'Asymptote'; one specifies the label as a
+double-quoted 'LaTeX' string, a coordinate, and an optional alignment
+direction:
+size(3cm);
+draw(unitsquare);
+label("$A$",(0,0),SW);
+label("$B$",(1,0),SE);
+label("$C$",(1,1),NE);
+label("$D$",(0,1),NW);
+
+ [./labelsquare]
+
+ 'Asymptote' uses the standard compass directions 'E=(1,0)',
+'N=(0,1)', 'NE=unit(N+E)', and 'ENE=unit(E+NE)', etc., which along with
+the directions 'up', 'down', 'right', and 'left' are defined as pairs in
+the 'Asymptote' base module 'plain' (a user who has a local variable
+named 'E' may access the compass direction 'E' by prefixing it with the
+name of the module where it is defined: 'plain.E').
+
+
+File: asymptote.info, Node: Paths, Prev: Labels, Up: Tutorial
+
+3.5 Paths
+=========
+
+This example draws a path that approximates a quarter circle, terminated
+with an arrowhead:
+size(100,0);
+draw((1,0){up}..{left}(0,1),Arrow);
+
+ [./quartercircle]
+Here the directions 'up' and 'left' in braces specify the outgoing and
+incoming directions at the points '(1,0)' and '(0,1)', respectively.
+
+ In general, a path is specified as a list of points (or other paths)
+interconnected with '--', which denotes a straight line segment, or
+'..', which denotes a cubic spline (*note Bezier curves::). Specifying
+a final '..cycle' creates a cyclic path that connects smoothly back to
+the initial node, as in this approximation (accurate to within 0.06%) of
+a unit circle:
+path unitcircle=E..N..W..S..cycle;
+
+An 'Asymptote' path, being connected, is equivalent to a 'PostScript
+subpath'. The '^^' binary operator, which requests that the pen be
+moved (without drawing or affecting endpoint curvatures) from the final
+point of the left-hand path to the initial point of the right-hand path,
+may be used to group several 'Asymptote' paths into a 'path[]' array
+(equivalent to a 'PostScript' path):
+size(0,100);
+path unitcircle=E..N..W..S..cycle;
+path g=scale(2)*unitcircle;
+filldraw(unitcircle^^g,evenodd+yellow,black);
+
+
+ [./superpath]
+
+The 'PostScript' even-odd fill rule here specifies that only the region
+bounded between the two unit circles is filled (*note fillrule::). In
+this example, the same effect can be achieved by using the default zero
+winding number fill rule, if one is careful to alternate the orientation
+of the paths:
+filldraw(unitcircle^^reverse(g),yellow,black);
+
+ The '^^' operator is used by the 'box(triple, triple)' function in
+the module 'three' to construct the edges of a cube 'unitbox' without
+retracing steps (*note three::):
+import three;
+
+currentprojection=orthographic(5,4,2,center=true);
+
+size(5cm);
+size3(3cm,5cm,8cm);
+
+draw(unitbox);
+
+dot(unitbox,red);
+
+label("$O$",(0,0,0),NW);
+label("(1,0,0)",(1,0,0),S);
+label("(0,1,0)",(0,1,0),E);
+label("(0,0,1)",(0,0,1),Z);
+
+ [./cube]
+
+ See section *note graph:: (or the online 'Asymptote' gallery and
+external links posted at <https://asymptote.sourceforge.io>) for further
+examples, including two-dimensional and interactive three-dimensional
+scientific graphs. Additional examples have been posted by Philippe
+Ivaldi at <http://www.piprime.fr/asymptote>.

+
+4 Drawing commands
+******************
+
+All of 'Asymptote''s graphical capabilities are based on four primitive
+commands. The three 'PostScript' drawing commands 'draw', 'fill', and
+'clip' add objects to a picture in the order in which they are executed,
+with the most recently drawn object appearing on top. The labeling
+command 'label' can be used to add text labels and external EPS images,
+which will appear on top of the 'PostScript' objects (since this is
+normally what one wants), but again in the relative order in which they
+were executed. After drawing objects on a picture, the picture can be
+output with the 'shipout' function (*note shipout::).
+
+ If you wish to draw 'PostScript' objects on top of labels (or
+verbatim 'tex' commands; *note tex::), the 'layer' command may be used
+to start a new 'PostScript/LaTeX' layer:
+void layer(picture pic=currentpicture);
+
+ The 'layer' function gives one full control over the order in which
+objects are drawn. Layers are drawn sequentially, with the most recent
+layer appearing on top. Within each layer, labels, images, and verbatim
+'tex' commands are always drawn after the 'PostScript' objects in that
+layer.
+
+ A page break can be generated with the command
+void newpage(picture pic=currentpicture);
+
+ While some of these drawing commands take many options, they all have
+sensible default values (for example, the picture argument defaults to
+currentpicture).
+

+File: asymptote.info, Node: draw, Next: fill, Prev: Drawing commands, Up: Drawing commands
+
+4.1 draw
+========
+
+void draw(picture pic=currentpicture, Label L="", path g,
+ align align=NoAlign, pen p=currentpen,
+ arrowbar arrow=None, arrowbar bar=None, margin margin=NoMargin,
+ Label legend="", marker marker=nomarker);
+
+ Draw the path 'g' on the picture 'pic' using pen 'p' for drawing,
+with optional drawing attributes (Label 'L', explicit label alignment
+'align', arrows and bars 'arrow' and 'bar', margins 'margin', legend,
+and markers 'marker'). Only one parameter, the path, is required. For
+convenience, the arguments 'arrow' and 'bar' may be specified in either
+order. The argument 'legend' is a Label to use in constructing an
+optional legend entry.
+
+ Bars are useful for indicating dimensions. The possible values of
+'bar' are 'None', 'BeginBar', 'EndBar' (or equivalently 'Bar'), and
+'Bars' (which draws a bar at both ends of the path). Each of these bar
+specifiers (except for 'None') will accept an optional real argument
+that denotes the length of the bar in 'PostScript' coordinates. The
+default bar length is 'barsize(pen)'.
+
+ The possible values of 'arrow' are 'None', 'Blank' (which draws no
+arrows or path), 'BeginArrow', 'MidArrow', 'EndArrow' (or equivalently
+'Arrow'), and 'Arrows' (which draws an arrow at both ends of the path).
+All of the arrow specifiers except for 'None' and 'Blank' may be given
+the optional arguments arrowhead 'arrowhead' (one of the predefined
+arrowhead styles 'DefaultHead', 'SimpleHead', 'HookHead', 'TeXHead'),
+real 'size' (arrowhead size in 'PostScript' coordinates), real 'angle'
+(arrowhead angle in degrees), filltype 'filltype' (one of 'FillDraw',
+'Fill', 'NoFill', 'UnFill', 'Draw') and (except for 'MidArrow' and
+'Arrows') a real 'position' (in the sense of 'point(path p, real t)')
+along the path where the tip of the arrow should be placed. The default
+arrowhead size when drawn with a pen 'p' is 'arrowsize(p)'. There are
+also arrow versions with slightly modified default values of 'size' and
+'angle' suitable for curved arrows: 'BeginArcArrow', 'EndArcArrow' (or
+equivalently 'ArcArrow'), 'MidArcArrow', and 'ArcArrows'.
+
+ Margins can be used to shrink the visible portion of a path by
+'labelmargin(p)' to avoid overlap with other drawn objects. Typical
+values of 'margin' are 'NoMargin', 'BeginMargin', 'EndMargin' (or
+equivalently 'Margin'), and 'Margins' (which leaves a margin at both
+ends of the path). One may use 'Margin(real begin, real end=begin)' to
+specify the size of the beginning and ending margin, respectively, in
+multiples of the units 'labelmargin(p)' used for aligning labels.
+Alternatively, 'BeginPenMargin', 'EndPenMargin' (or equivalently
+'PenMargin'), 'PenMargins', 'PenMargin(real begin, real end=begin)'
+specify a margin in units of the pen line width, taking account of the
+pen line width when drawing the path or arrow. For example, use
+'DotMargin', an abbreviation for
+'PenMargin(-0.5*dotfactor,0.5*dotfactor)', to draw from the usual
+beginning point just up to the boundary of an end dot of width
+'dotfactor*linewidth(p)'. The qualifiers 'BeginDotMargin',
+'EndDotMargin', and 'DotMargins' work similarly. The qualifier
+'TrueMargin(real begin, real end=begin)' allows one to specify a margin
+directly in 'PostScript' units, independent of the pen line width.
+
+ The use of arrows, bars, and margins is illustrated by the examples
+'Pythagoras.asy' and 'sqrtx01.asy'.
+
+ The legend for a picture 'pic' can be fit and aligned to a frame with
+the routine:
+frame legend(picture pic=currentpicture, int perline=1,
+ real xmargin=legendmargin, real ymargin=xmargin,
+ real linelength=legendlinelength,
+ real hskip=legendhskip, real vskip=legendvskip,
+ real maxwidth=0, real maxheight=0,
+ bool hstretch=false, bool vstretch=false, pen p=currentpen);
+Here 'xmargin' and 'ymargin' specify the surrounding x and y margins,
+'perline' specifies the number of entries per line (default 1; 0 means
+choose this number automatically), 'linelength' specifies the length of
+the path lines, 'hskip' and 'vskip' specify the line skip (as a multiple
+of the legend entry size), 'maxwidth' and 'maxheight' specify optional
+upper limits on the width and height of the resulting legend (0 means
+unlimited), 'hstretch' and 'vstretch' allow the legend to stretch
+horizontally or vertically, and 'p' specifies the pen used to draw the
+bounding box. The legend frame can then be added and aligned about a
+point on a picture 'dest' using 'add' or 'attach' (*note add about::).
+
+ To draw a dot, simply draw a path containing a single point. The
+'dot' command defined in the module 'plain' draws a dot having a
+diameter equal to an explicit pen line width or the default line width
+magnified by 'dotfactor' (6 by default), using the specified filltype
+(*note filltype::) or 'dotfilltype' ('Fill' by default):
+void dot(frame f, pair z, pen p=currentpen, filltype filltype=dotfilltype);
+void dot(picture pic=currentpicture, pair z, pen p=currentpen,
+ filltype filltype=dotfilltype);
+void dot(picture pic=currentpicture, Label L, pair z, align align=NoAlign,
+ string format=defaultformat, pen p=currentpen, filltype filltype=dotfilltype);
+void dot(picture pic=currentpicture, Label[] L=new Label[], pair[] z,
+ align align=NoAlign, string format=defaultformat, pen p=currentpen,
+ filltype filltype=dotfilltype);
+void dot(picture pic=currentpicture, path[] g, pen p=currentpen,
+ filltype filltype=dotfilltype);
+void dot(picture pic=currentpicture, Label L, pen p=currentpen,
+ filltype filltype=dotfilltype);
+
+ If the variable 'Label' is given as the 'Label' argument to the third
+routine, the 'format' argument will be used to format a string based on
+the dot location (here 'defaultformat' is '"$%.4g$"'). The fourth
+routine draws a dot at every point of a pair array 'z'. One can also
+draw a dot at every node of a path:
+void dot(picture pic=currentpicture, Label[] L=new Label[],
+ explicit path g, align align=RightSide, string format=defaultformat,
+ pen p=currentpen, filltype filltype=dotfilltype);
+ See *note pathmarkers:: and *note markers:: for more general methods
+for marking path nodes.
+
+ To draw a fixed-sized object (in 'PostScript' coordinates) about the
+user coordinate 'origin', use the routine
+void draw(pair origin, picture pic=currentpicture, Label L="", path g,
+ align align=NoAlign, pen p=currentpen, arrowbar arrow=None,
+ arrowbar bar=None, margin margin=NoMargin, Label legend="",
+ marker marker=nomarker);
+
+
+File: asymptote.info, Node: fill, Next: clip, Prev: draw, Up: Drawing commands
+
+4.2 fill
+========
+
+void fill(picture pic=currentpicture, path g, pen p=currentpen);
+
+ Fill the interior region bounded by the cyclic path 'g' on the
+picture 'pic', using the pen 'p'.
+
+ There is also a convenient 'filldraw' command, which fills the path
+and then draws in the boundary. One can specify separate pens for each
+operation:
+void filldraw(picture pic=currentpicture, path g, pen fillpen=currentpen,
+ pen drawpen=currentpen);
+
+ This fixed-size version of 'fill' allows one to fill an object
+described in 'PostScript' coordinates about the user coordinate
+'origin':
+void fill(pair origin, picture pic=currentpicture, path g, pen p=currentpen);
+
+This is just a convenient abbreviation for the commands:
+picture opic;
+fill(opic,g,p);
+add(pic,opic,origin);
+
+ The routine
+void filloutside(picture pic=currentpicture, path g, pen p=currentpen);
+fills the region exterior to the path 'g', out to the current boundary
+of picture 'pic'.
+
+ Lattice gradient shading varying smoothly over a two-dimensional
+array of pens 'p', using fill rule 'fillrule', can be produced with
+void latticeshade(picture pic=currentpicture, path g, bool stroke=false,
+ pen fillrule=currentpen, pen[][] p)
+ If 'stroke=true', the region filled is the same as the region that
+would be drawn by 'draw(pic,g,zerowinding)'; in this case the path 'g'
+need not be cyclic. The pens in 'p' must belong to the same color
+space. One can use the functions 'rgb(pen)' or 'cmyk(pen)' to promote
+pens to a higher color space, as illustrated in the example file
+'latticeshading.asy'.
+
+ Axial gradient shading varying smoothly from 'pena' to 'penb' in the
+direction of the line segment 'a--b' can be achieved with
+void axialshade(picture pic=currentpicture, path g, bool stroke=false,
+ pen pena, pair a, bool extenda=true,
+ pen penb, pair b, bool extendb=true);
+The boolean parameters 'extenda' and 'extendb' indicate whether the
+shading should extend beyond the axis endpoints 'a' and 'b'. An example
+of axial shading is provided in the example file 'axialshade.asy'.
+
+ Radial gradient shading varying smoothly from 'pena' on the circle
+with center 'a' and radius 'ra' to 'penb' on the circle with center 'b'
+and radius 'rb' is similar:
+void radialshade(picture pic=currentpicture, path g, bool stroke=false,
+ pen pena, pair a, real ra, bool extenda=true,
+ pen penb, pair b, real rb, bool extendb=true);
+The boolean parameters 'extenda' and 'extendb' indicate whether the
+shading should extend beyond the radii 'a' and 'b'. Illustrations of
+radial shading are provided in the example files 'shade.asy',
+'ring.asy', and 'shadestroke.asy'.
+
+ Gouraud shading using fill rule 'fillrule' and the vertex colors in
+the pen array 'p' on a triangular lattice defined by the vertices 'z'
+and edge flags 'edges' is implemented with
+void gouraudshade(picture pic=currentpicture, path g, bool stroke=false,
+ pen fillrule=currentpen, pen[] p, pair[] z,
+ int[] edges);
+void gouraudshade(picture pic=currentpicture, path g, bool stroke=false,
+ pen fillrule=currentpen, pen[] p, int[] edges);
+In the second form, the elements of 'z' are taken to be successive nodes
+of path 'g'. The pens in 'p' must belong to the same color space.
+Illustrations of Gouraud shading are provided in the example file
+'Gouraud.asy'. The edge flags used in Gouraud shading are documented
+here:
+ <https://www.adobe.com/content/dam/acom/en/devnet/postscript/pdfs/TN5600.SmoothShading.pdf>
+
+ Tensor product shading using clipping path 'g', fill rule 'fillrule'
+on patches bounded by the n cyclic paths of length 4 in path array 'b',
+using the vertex colors specified in the n \times 4 pen array 'p' and
+internal control points in the n \times 4 array 'z', is implemented with
+void tensorshade(picture pic=currentpicture, path[] g, bool stroke=false,
+ pen fillrule=currentpen, pen[][] p, path[] b=g,
+ pair[][] z=new pair[][]);
+If the array 'z' is empty, Coons shading, in which the color control
+points are calculated automatically, is used. The pens in 'p' must
+belong to the same color space. A simpler interface for the case of a
+single patch (n=1) is also available:
+void tensorshade(picture pic=currentpicture, path g, bool stroke=false,
+ pen fillrule=currentpen, pen[] p, path b=g,
+ pair[] z=new pair[]);
+ One can also smoothly shade the regions between consecutive paths of
+a sequence using a given array of pens:
+void draw(picture pic=currentpicture, pen fillrule=currentpen, path[] g,
+ pen[] p);
+Illustrations of tensor product and Coons shading are provided in the
+example files 'tensor.asy', 'Coons.asy', 'BezierPatch.asy', and
+'rainbow.asy'.
+
+ More general shading possibilities are available using TeX engines
+that produce PDF output (*note texengines::): the routine
+void functionshade(picture pic=currentpicture, path[] g, bool stroke=false,
+ pen fillrule=currentpen, string shader);
+shades on picture 'pic' the interior of path 'g' according to fill rule
+'fillrule' using the 'PostScript' calculator routine specified by the
+string 'shader'; this routine takes 2 arguments, each in [0,1], and
+returns 'colors(fillrule).length' color components. Function shading is
+illustrated in the example 'functionshading.asy'.
+
+ The following routine uses 'evenodd' clipping together with the '^^'
+operator to unfill a region:
+
+void unfill(picture pic=currentpicture, path g);

+4.3 clip
+========
+
+void clip(picture pic=currentpicture, path g, stroke=false,
+ pen fillrule=currentpen);
+
+ Clip the current contents of picture 'pic' to the region bounded by
+the path 'g', using fill rule 'fillrule' (*note fillrule::). If
+'stroke=true', the clipped portion is the same as the region that would
+be drawn with 'draw(pic,g,zerowinding)'; in this case the path 'g' need
+not be cyclic. While clipping has no notion of depth (it transcends
+layers and even pages), one can localize clipping to a temporary
+picture, which can then be added to 'pic'. For an illustration of
+picture clipping, see the first example in *note LaTeX usage::.
+
+
+File: asymptote.info, Node: label, Prev: clip, Up: Drawing commands
+
+4.4 label
+=========
+
+void label(picture pic=currentpicture, Label L, pair position,
+ align align=NoAlign, pen p=currentpen, filltype filltype=NoFill)
+
+ Draw Label 'L' on picture 'pic' using pen 'p'. If 'align' is
+'NoAlign', the label will be centered at user coordinate 'position';
+otherwise it will be aligned in the direction of 'align' and displaced
+from 'position' by the 'PostScript' offset 'align*labelmargin(p)'. The
+constant 'Align' can be used to align the bottom-left corner of the
+label at 'position'. The Label 'L' can either be a string or the
+structure obtained by calling one of the functions
+Label Label(string s="", pair position, align align=NoAlign,
+ pen p=nullpen, embed embed=Rotate, filltype filltype=NoFill);
+Label Label(string s="", align align=NoAlign,
+ pen p=nullpen, embed embed=Rotate, filltype filltype=NoFill);
+Label Label(Label L, pair position, align align=NoAlign,
+ pen p=nullpen, embed embed=L.embed, filltype filltype=NoFill);
+Label Label(Label L, align align=NoAlign,
+ pen p=nullpen, embed embed=L.embed, filltype filltype=NoFill);
+ The text of a Label can be scaled, slanted, rotated, or shifted by
+multiplying it on the left by an affine transform (*note Transforms::).
+For example, 'rotate(45)*xscale(2)*L' first scales 'L' in the x
+direction and then rotates it counterclockwise by 45 degrees. The final
+position of a Label can also be shifted by a 'PostScript' coordinate
+translation: 'shift(10,0)*L'. An explicit pen specified within the
+Label overrides other pen arguments. The 'embed' argument determines
+how the Label should transform with the embedding picture:
+'Shift'
+ only shift with embedding picture;
+
+'Rotate'
+ only shift and rotate with embedding picture (default);
+
+'Rotate(pair z)'
+ rotate with (picture-transformed) vector 'z'.
+
+'Slant'
+ only shift, rotate, slant, and reflect with embedding picture;
+
+'Scale'
+ shift, rotate, slant, reflect, and scale with embedding picture.
+
+ To add a label to a path, use
+void label(picture pic=currentpicture, Label L, path g, align align=NoAlign,
+ pen p=currentpen, filltype filltype=NoFill);
+ By default the label will be positioned at the midpoint of the path.
+An alternative label position (in the sense of 'point(path p, real t)')
+may be specified as a real value for 'position' in constructing the
+Label. The position 'Relative(real)' specifies a location relative to
+the total arclength of the path. These convenient abbreviations are
+predefined:
+position BeginPoint=Relative(0);
+position MidPoint=Relative(0.5);
+position EndPoint=Relative(1);
+
+ Path labels are aligned in the direction 'align', which may be
+specified as an absolute compass direction (pair) or a direction
+'Relative(pair)' measured relative to a north axis in the local
+direction of the path. For convenience 'LeftSide', 'Center', and
+'RightSide' are defined as 'Relative(W)', 'Relative((0,0))', and
+'Relative(E)', respectively. Multiplying 'LeftSide' and 'RightSide' on
+the left by a real scaling factor will move the label further away from
+or closer to the path.
+
+ A label with a fixed-size arrow of length 'arrowlength' pointing to
+'b' from direction 'dir' can be produced with the routine
+void arrow(picture pic=currentpicture, Label L="", pair b, pair dir,
+ real length=arrowlength, align align=NoAlign,
+ pen p=currentpen, arrowbar arrow=Arrow, margin margin=EndMargin);
+ If no alignment is specified (either in the Label or as an explicit
+argument), the optional Label will be aligned in the direction 'dir',
+using margin 'margin'.
+
+ The function 'string graphic(string name, string options="")' returns
+a string that can be used to include an encapsulated 'PostScript' (EPS)
+file. Here, 'name' is the name of the file to include and 'options' is
+a string containing a comma-separated list of optional bounding box
+('bb=llx lly urx ury'), width ('width=value'), height ('height=value'),
+rotation ('angle=value'), scaling ('scale=factor'), clipping
+('clip=bool'), and draft mode ('draft=bool') parameters. The 'layer()'
+function can be used to force future objects to be drawn on top of the
+included image:
+label(graphic("file.eps","width=1cm"),(0,0),NE);
+layer();
+
+ The 'string baseline(string s, string template="\strut")' function
+can be used to enlarge the bounding box of labels to match a given
+template, so that their baselines will be typeset on a horizontal line.
+See 'Pythagoras.asy' for an example.
+
+ One can prevent labels from overwriting one another with the
+'overwrite' pen attribute (*note overwrite::).
+
+ The structure 'object' defined in 'plain_Label.asy' allows Labels and
+frames to be treated in a uniform manner. A group of objects may be
+packed together into single frame with the routine
+frame pack(pair align=2S ... object inset[]);
+To draw or fill a box (or ellipse or other path) around a Label and
+return the bounding object, use one of the routines
+object draw(picture pic=currentpicture, Label L, envelope e,
+ real xmargin=0, real ymargin=xmargin, pen p=currentpen,
+ filltype filltype=NoFill, bool above=true);
+object draw(picture pic=currentpicture, Label L, envelope e, pair position,
+ real xmargin=0, real ymargin=xmargin, pen p=currentpen,
+ filltype filltype=NoFill, bool above=true);
+Here 'envelope' is a boundary-drawing routine such as 'box', 'roundbox',
+or 'ellipse' defined in 'plain_boxes.asy' (*note envelope::).
+
+ The function 'path[] texpath(Label L)' returns the path array that
+TeX would fill to draw the Label 'L'.
+
+ The 'string minipage(string s, width=100pt)' function can be used to
+format string 's' into a paragraph of width 'width'. This example uses
+'minipage', 'clip', and 'graphic' to produce a CD label:
+
+ [./CDlabel]
+size(11.7cm,11.7cm);
+
+asy(nativeformat(),"logo");
+
+fill(unitcircle^^(scale(2/11.7)*unitcircle),
+ evenodd+rgb(124/255,205/255,124/255));
+label(scale(1.1)*minipage(

+
+5 Bezier curves
+***************
+
+Each interior node of a cubic spline may be given a direction prefix or
+suffix '{dir}': the direction of the pair 'dir' specifies the direction
+of the incoming or outgoing tangent, respectively, to the curve at that
+node. Exterior nodes may be given direction specifiers only on their
+interior side.
+
+ A cubic spline between the node z_0, with postcontrol point c_0, and
+the node z_1, with precontrol point c_1, is computed as the Bezier curve
+
+ [(1-t)^3*z_0+3t(1-t)^2*c_0+3t^2(1-t)*c_1+t^3*z_1 for 0 <=t <= 1.]
+
+ As illustrated in the diagram below, the third-order midpoint (m_5)
+constructed from two endpoints z_0 and z_1 and two control points c_0
+and c_1, is the point corresponding to t=1/2 on the Bezier curve formed
+by the quadruple (z_0, c_0, c_1, z_1). This allows one to recursively
+construct the desired curve, by using the newly extracted third-order
+midpoint as an endpoint and the respective second- and first-order
+midpoints as control points:
+
+ [./bezier2]
+
+ Here m_0, m_1 and m_2 are the first-order midpoints, m_3 and m_4 are
+the second-order midpoints, and m_5 is the third-order midpoint. The
+curve is then constructed by recursively applying the algorithm to (z_0,
+m_0, m_3, m_5) and (m_5, m_4, m_2, z_1).
+
+ In fact, an analogous property holds for points located at any
+fraction t in [0,1] of each segment, not just for midpoints (t=1/2).
+
+ The Bezier curve constructed in this manner has the following
+properties:
+
+ * It is entirely contained in the convex hull of the given four
+ points.
+
+ * It starts heading from the first endpoint to the first control
+ point and finishes heading from the second control point to the
+ second endpoint.
+
+ The user can specify explicit control points between two nodes like
+this:
+draw((0,0)..controls (0,100) and (100,100)..(100,0));
+
+ However, it is usually more convenient to just use the '..' operator,
+which tells 'Asymptote' to choose its own control points using the
+algorithms described in Donald Knuth's monograph, The MetaFontbook,
+Chapter 14. The user can still customize the guide (or path) by
+specifying direction, tension, and curl values.
+
+ The higher the tension, the straighter the curve is, and the more it
+approximates a straight line. One can change the spline tension from
+its default value of 1 to any real value greater than or equal to 0.75
+(cf. John D. Hobby, Discrete and Computational Geometry 1, 1986):
+draw((100,0)..tension 2 ..(100,100)..(0,100));
+draw((100,0)..tension 3 and 2 ..(100,100)..(0,100));
+draw((100,0)..tension atleast 2 ..(100,100)..(0,100));
+
+ In these examples there is a space between '2' and '..'. This is
+needed as '2.' is interpreted as a numerical constant.
+
+ The curl parameter specifies the curvature at the endpoints of a path
+(0 means straight; the default value of 1 means approximately circular):
+draw((100,0){curl 0}..(100,100)..{curl 0}(0,100));
+
+ The 'MetaPost ...' path connector, which requests, when possible, an
+inflection-free curve confined to a triangle defined by the endpoints
+and directions, is implemented in 'Asymptote' as the convenient
+abbreviation '::' for '..tension atleast 1 ..' (the ellipsis '...' is
+used in 'Asymptote' to indicate a variable number of arguments; *note
+Rest arguments::). For example, compare
+draw((0,0){up}..(100,25){right}..(200,0){down});
+
+ [./dots]
+with
+draw((0,0){up}::(100,25){right}::(200,0){down});
+
+ [./colons]
+
+ The '---' connector is an abbreviation for '..tension atleast
+infinity..' and the '&' connector concatenates two paths, after first
+stripping off the last node of the first path (which normally should
+coincide with the first node of the second path).

+ 'Asymptote' supports 'while', 'do', 'break', and 'continue'

+
+// Iterate over an array
+int[] array={1,1,2,3,5};
+for(int k : array) {
+ write(k);
+}
+In addition, it supports many features beyond the ones found in those
+languages.

+
+6.1 Data types
+==============
+
+'Asymptote' supports the following data types (in addition to
+user-defined types):
+
+'void'
+ The void type is used only by functions that take or return no
+ arguments.
+
+'bool'
+ a boolean type that can only take on the values 'true' or 'false'.
+ For example:
+ bool b=true;
+
+ defines a boolean variable 'b' and initializes it to the value
+ 'true'. If no initializer is given:
+ bool b;
+
+ the value 'false' is assumed.
+
+'bool3'
+ an extended boolean type that can take on the values 'true',
+ 'default', or 'false'. A bool3 type can be cast to or from a bool.
+ The default initializer for bool3 is 'default'.
+
+'int'
+ an integer type; if no initializer is given, the implicit value '0'
+ is assumed. The minimum allowed value of an integer is 'intMin'
+ and the maximum value is 'intMax'.
+
+'real'
+ a real number; this should be set to the highest-precision native
+ floating-point type on the architecture. The implicit initializer
+ for reals is '0.0'. Real numbers have precision 'realEpsilon',
+ with 'realDigits' significant digits. The smallest positive real
+ number is 'realMin' and the largest positive real number is
+ 'realMax'. The variables 'inf' and 'nan', along with the function
+ 'bool isnan(real x)' are useful when floating-point exceptions are
+ masked with the '-mask' command-line option (the default in
+ interactive mode).
+
+'pair'
+ complex number, that is, an ordered pair of real components
+ '(x,y)'. The real and imaginary parts of a pair 'z' can read as
+ 'z.x' and 'z.y'. We say that 'x' and 'y' are virtual members of
+ the data element pair; they cannot be directly modified, however.
+ The implicit initializer for pairs is '(0.0,0.0)'.
+
+ There are a number of ways to take the complex conjugate of a pair:
+ pair z=(3,4);
+ z=(z.x,-z.y);
+ z=z.x-I*z.y;
+ z=conj(z);
+
+ Here 'I' is the pair '(0,1)'. A number of built-in functions are
+ defined for pairs:
+
+ 'pair conj(pair z)'
+ returns the conjugate of 'z';
+
+ 'real length(pair z)'
+ returns the complex modulus |'z'| of its argument 'z'. For
+ example,
+ pair z=(3,4);
+ length(z);
+ returns the result 5. A synonym for 'length(pair)' is
+ 'abs(pair)'. The function 'abs2(pair z)' returns |'z'|^2;
+
+ 'real angle(pair z, bool warn=true)'
+ returns the angle of 'z' in radians in the interval
+ [-'pi','pi'] or '0' if 'warn' is 'false' and 'z=(0,0)' (rather
+ than producing an error);
+
+ 'real degrees(pair z, bool warn=true)'
+ returns the angle of 'z' in degrees in the interval [0,360) or
+ '0' if 'warn' is 'false' and 'z=(0,0)' (rather than producing
+ an error);
+
+ 'pair unit(pair z)'
+ returns a unit vector in the direction of the pair 'z';
+
+ 'pair expi(real angle)'
+ returns a unit vector in the direction 'angle' measured in
+ radians;
+
+ 'pair dir(real degrees)'
+ returns a unit vector in the direction 'degrees' measured in
+ degrees;
+
+ 'real xpart(pair z)'
+ returns 'z.x';
+
+ 'real ypart(pair z)'
+ returns 'z.y';
+
+ 'pair realmult(pair z, pair w)'
+ returns the element-by-element product '(z.x*w.x,z.y*w.y)';
+
+ 'real dot(explicit pair z, explicit pair w)'
+ returns the dot product 'z.x*w.x+z.y*w.y';
+
+ 'real cross(explicit pair z, explicit pair w)'
+ returns the 2D scalar product 'z.x*w.y-z.y*w.x';
+
+ 'real orient(pair a, pair b, pair c);'
+ returns a positive (negative) value if 'a--b--c--cycle' is
+ oriented counterclockwise (clockwise) or zero if all three
+ points are colinear. Equivalently, a positive (negative)
+ value is returned if 'c' lies to the left (right) of the line
+ through 'a' and 'b' or zero if 'c' lies on this line. The
+ value returned can be expressed in terms of the 2D scalar
+ cross product as 'cross(a-c,b-c)', which is the determinant
+ |a.x a.y 1|
+ |b.x b.y 1|
+ |c.x c.y 1|
+
+ 'real incircle(pair a, pair b, pair c, pair d);'
+ returns a positive (negative) value if 'd' lies inside
+ (outside) the circle passing through the
+ counterclockwise-oriented points 'a,b,c' or zero if 'd' lies
+ on the this circle. The value returned is the determinant
+ |a.x a.y a.x^2+a.y^2 1|
+ |b.x b.y b.x^2+b.y^2 1|
+ |c.x c.y c.x^2+c.y^2 1|
+ |d.x d.y d.x^2+d.y^2 1|
+
+ 'pair minbound(pair z, pair w)'
+ returns '(min(z.x,w.x),min(z.y,w.y))';
+
+ 'pair maxbound(pair z, pair w)'
+ returns '(max(z.x,w.x),max(z.y,w.y))'.
+
+'triple'
+ an ordered triple of real components '(x,y,z)' used for
+ three-dimensional drawings. The respective components of a triple
+ 'v' can read as 'v.x', 'v.y', and 'v.z'. The implicit initializer
+ for triples is '(0.0,0.0,0.0)'.
+
+ Here are the built-in functions for triples:
+ 'real length(triple v)'
+ returns the length |'v'| of its argument 'v'. A synonym for
+ 'length(triple)' is 'abs(triple)'. The function 'abs2(triple
+ v)' returns |'v'|^2;
+
+ 'real polar(triple v, bool warn=true)'
+ returns the colatitude of 'v' measured from the z axis in
+ radians or '0' if 'warn' is 'false' and 'v=O' (rather than
+ producing an error);
+
+ 'real azimuth(triple v, bool warn=true)'
+ returns the longitude of 'v' measured from the x axis in
+ radians or '0' if 'warn' is 'false' and 'v.x=v.y=0' (rather
+ than producing an error);
+
+ 'real colatitude(triple v, bool warn=true)'
+ returns the colatitude of 'v' measured from the z axis in
+ degrees or '0' if 'warn' is 'false' and 'v=O' (rather than
+ producing an error);
+
+ 'real latitude(triple v, bool warn=true)'
+ returns the latitude of 'v' measured from the xy plane in
+ degrees or '0' if 'warn' is 'false' and 'v=O' (rather than
+ producing an error);
+
+ 'real longitude(triple v, bool warn=true)'
+ returns the longitude of 'v' measured from the x axis in
+ degrees or '0' if 'warn' is 'false' and 'v.x=v.y=0' (rather
+ than producing an error);
+
+ 'triple unit(triple v)'
+ returns a unit triple in the direction of the triple 'v';
+
+ 'triple expi(real polar, real azimuth)'
+ returns a unit triple in the direction '(polar,azimuth)'
+ measured in radians;
+
+ 'triple dir(real colatitude, real longitude)'
+ returns a unit triple in the direction
+ '(colatitude,longitude)' measured in degrees;
+
+ 'real xpart(triple v)'
+ returns 'v.x';
+
+ 'real ypart(triple v)'
+ returns 'v.y';
+
+ 'real zpart(triple v)'
+ returns 'v.z';
+
+ 'real dot(triple u, triple v)'
+ returns the dot product 'u.x*v.x+u.y*v.y+u.z*v.z';
+
+ 'triple cross(triple u, triple v)'
+ returns the cross product
+
+ '(u.y*v.z-u.z*v.y,u.z*v.x-u.x*v.z,u.x*v.y-v.x*u.y)';
+
+ 'triple minbound(triple u, triple v)'
+ returns '(min(u.x,v.x),min(u.y,v.y),min(u.z,v.z))';
+
+ 'triple maxbound(triple u, triple v)'
+ returns '(max(u.x,v.x),max(u.y,v.y),max(u.z,v.z)').
+
+'string'
+ a character string, implemented using the STL 'string' class.
+
+ Strings delimited by double quotes ('"') are subject to the
+ following mappings to allow the use of double quotes in TeX
+ (e.g. for using the 'babel' package, *note babel::):
+
+ * \" maps to "
+ * \\ maps to \\
+
+ Strings delimited by single quotes (''') have the same mappings as
+ character strings in ANSI 'C':
+
+ * \' maps to '
+ * \" maps to "
+ * \? maps to ?
+ * \\ maps to backslash
+ * \a maps to alert
+ * \b maps to backspace
+ * \f maps to form feed
+ * \n maps to newline
+ * \r maps to carriage return
+ * \t maps to tab
+ * \v maps to vertical tab
+ * \0-\377 map to corresponding octal byte
+ * \x0-\xFF map to corresponding hexadecimal byte
+
+ The implicit initializer for strings is the empty string '""'.
+ Strings may be concatenated with the '+' operator. In the
+ following string functions, position '0' denotes the start of the
+ string:
+
+ 'int length(string s)'
+ returns the length of the string 's';
+
+ 'int find(string s, string t, int pos=0)'
+ returns the position of the first occurrence of string 't' in
+ string 's' at or after position 'pos', or -1 if 't' is not a
+ substring of 's';
+
+ 'int rfind(string s, string t, int pos=-1)'
+ returns the position of the last occurrence of string 't' in
+ string 's' at or before position 'pos' (if 'pos'=-1, at the
+ end of the string 's'), or -1 if 't' is not a substring of
+ 's';
+
+ 'string insert(string s, int pos, string t)'
+ returns the string formed by inserting string 't' at position
+ 'pos' in 's';
+
+ 'string erase(string s, int pos, int n)'
+ returns the string formed by erasing the string of length 'n'
+ (if 'n'=-1, to the end of the string 's') at position 'pos' in
+ 's';
+
+ 'string substr(string s, int pos, int n=-1)'
+ returns the substring of 's' starting at position 'pos' and of
+ length 'n' (if 'n'=-1, until the end of the string 's');
+
+ 'string reverse(string s)'
+ returns the string formed by reversing string 's';
+
+ 'string replace(string s, string before, string after)'
+ returns a string with all occurrences of the string 'before'
+ in the string 's' changed to the string 'after';
+
+ 'string replace(string s, string[][] table)'
+ returns a string constructed by translating in string 's' all
+ occurrences of the string 'before' in an array 'table' of
+ string pairs {'before','after'} to the corresponding string
+ 'after';
+
+ 'string[] split(string s, string delimiter="")'
+ returns an array of strings obtained by splitting 's' into
+ substrings delimited by 'delimiter' (an empty delimiter
+ signifies a space, but with duplicate delimiters discarded);
+
+ 'string[] array(string s)'
+ returns an array of strings obtained by splitting 's' into
+ individual characters. The inverse operation is provided by
+ 'operator +(...string[] a)'.
+
+ 'string format(string s, int n, string locale="")'
+ returns a string containing 'n' formatted according to the
+ C-style format string 's' using locale 'locale' (or the
+ current locale if an empty string is specified), following the
+ behaviour of the C function 'fprintf'), except that only one
+ data field is allowed.
+
+ 'string format(string s=defaultformat, bool forcemath=false, string s=defaultseparator, real x, string locale="")'
+ returns a string containing 'x' formatted according to the
+ C-style format string 's' using locale 'locale' (or the

+
+ 'string time(string format="%a %b %d %T %Z %Y")'
+ returns the current time formatted by the ANSI C routine

+ locale. Thus
+ time();
+ time("%a %b %d %H:%M:%S %Z %Y");
+
+ are equivalent ways of returning the current time in the
+ default format used by the 'UNIX' 'date' command;
+
+ 'int seconds(string t="", string format="")'
+ returns the time measured in seconds after the Epoch (Thu Jan
+ 01 00:00:00 UTC 1970) as determined by the ANSI C routine
+ 'strptime' according to the string 'format' using the current

+
+ 'string time(int seconds, string format="%a %b %d %T %Z %Y")'

+ time(seconds()-24*60*60);
+
+ 'int system(string s)'
+ 'int system(string[] s)'
+ if the setting 'safe' is false, call the arbitrary system

+
+ 'void abort(string s="")'
+ aborts execution (with a non-zero return code in batch mode);

+
+6.2 Paths and guides
+====================
+
+'path'
+ a cubic spline resolved into a fixed path. The implicit
+ initializer for paths is 'nullpath'.
+
+ For example, the routine 'circle(pair c, real r)', which returns a
+ Bezier curve approximating a circle of radius 'r' centered on 'c',
+ is based on 'unitcircle' (*note unitcircle::):
+ path circle(pair c, real r)
+ {
+ return shift(c)*scale(r)*unitcircle;
+ }
+ If high accuracy is needed, a true circle may be produced with the
+ routine 'Circle' defined in the module 'graph':
+ import graph;
+ path Circle(pair c, real r, int n=nCircle);
+
+ A circular arc consistent with 'circle' centered on 'c' with radius
+ 'r' from 'angle1' to 'angle2' degrees, drawing counterclockwise if
+ 'angle2 >= angle1', can be constructed with
+ path arc(pair c, real r, real angle1, real angle2);
+ One may also specify the direction explicitly:
+ path arc(pair c, real r, real angle1, real angle2, bool direction);
+ Here the direction can be specified as CCW (counter-clockwise) or
+ CW (clockwise). For convenience, an arc centered at 'c' from pair
+ 'z1' to 'z2' (assuming '|z2-c|=|z1-c|') in the may also be
+ constructed with
+ path arc(pair c, explicit pair z1, explicit pair z2,
+ bool direction=CCW)
+
+ If high accuracy is needed, true arcs may be produced with routines
+ in the module 'graph' that produce Bezier curves with 'n' control
+ points:
+ import graph;
+ path Arc(pair c, real r, real angle1, real angle2, bool direction,
+ int n=nCircle);
+ path Arc(pair c, real r, real angle1, real angle2, int n=nCircle);
+ path Arc(pair c, explicit pair z1, explicit pair z2,
+ bool direction=CCW, int n=nCircle);
+
+ An ellipse can be drawn with the routine
+ path ellipse(pair c, real a, real b)
+ {
+ return shift(c)*scale(a,b)*unitcircle;
+ }
+
+ A brace can be constructed between pairs 'a' and 'b' with
+ path brace(pair a, pair b, real amplitude=bracedefaultratio*length(b-a));
+
+ This example illustrates the use of all five guide connectors
+ discussed in *note Tutorial:: and *note Bezier curves:::
+ size(300,0);
+ pair[] z=new pair[10];
+
+ z[0]=(0,100); z[1]=(50,0); z[2]=(180,0);
+
+ for(int n=3; n <= 9; ++n)
+ z[n]=z[n-3]+(200,0);

+ path p=z[0]..z[1]---z[2]::{up}z[3]

+ draw(p,grey+linewidth(4mm));
+
+ dot(z);
+
+ [./join]
+
+ Here are some useful functions for paths:
+
+ 'int length(path p);'
+ This is the number of (linear or cubic) segments in path 'p'.
+ If 'p' is cyclic, this is the same as the number of nodes in
+ 'p'.
+
+ 'int size(path p);'
+ This is the number of nodes in the path 'p'. If 'p' is
+ cyclic, this is the same as 'length(p)'.
+
+ 'bool cyclic(path p);'
+ returns 'true' iff path 'p' is cyclic.
+
+ 'bool straight(path p, int i);'
+ returns 'true' iff the segment of path 'p' between node 'i'
+ and node 'i+1' is straight.
+
+ 'bool piecewisestraight(path p)'
+ returns 'true' iff the path 'p' is piecewise straight.
+
+ 'pair point(path p, int t);'
+ If 'p' is cyclic, return the coordinates of node 't' mod
+ 'length(p)'. Otherwise, return the coordinates of node 't',
+ unless 't' < 0 (in which case 'point(0)' is returned) or 't' >
+ 'length(p)' (in which case 'point(length(p))' is returned).
+
+ 'pair point(path p, real t);'
+ This returns the coordinates of the point between node
+ 'floor(t)' and 'floor(t)+1' corresponding to the cubic spline
+ parameter 't-floor(t)' (*note Bezier curves::). If 't' lies
+ outside the range [0,'length(p)'], it is first reduced modulo
+ 'length(p)' in the case where 'p' is cyclic or else converted
+ to the corresponding endpoint of 'p'.
+
+ 'pair dir(path p, int t, int sign=0, bool normalize=true);'
+ If 'sign < 0', return the direction (as a pair) of the

+
+ 'pair dir(path p, real t, bool normalize=true);'
+ returns the direction of the tangent to path 'p' at the point
+ between node 'floor(t)' and 'floor(t)+1' corresponding to the
+ cubic spline parameter 't-floor(t)' (*note Bezier curves::).
+
+ 'pair dir(path p)'
+ returns dir(p,length(p)).
+
+ 'pair dir(path p, path q)'
+ returns unit(dir(p)+dir(q)).
+
+ 'pair accel(path p, int t, int sign=0);'
+ If 'sign < 0', return the acceleration of the incoming path
+ 'p' at node 't'; if 'sign > 0', return the acceleration of the
+ outgoing path. If 'sign=0', the mean of these two
+ accelerations is returned.
+
+ 'pair accel(path p, real t);'
+ returns the acceleration of the path 'p' at the point 't'.
+
+ 'real radius(path p, real t);'
+ returns the radius of curvature of the path 'p' at the point
+ 't'.
+
+ 'pair precontrol(path p, int t);'
+ returns the precontrol point of 'p' at node 't'.
+
+ 'pair precontrol(path p, real t);'
+ returns the effective precontrol point of 'p' at parameter
+ 't'.
+
+ 'pair postcontrol(path p, int t);'
+ returns the postcontrol point of 'p' at node 't'.
+
+ 'pair postcontrol(path p, real t);'
+ returns the effective postcontrol point of 'p' at parameter
+ 't'.
+
+ 'real arclength(path p);'
+ returns the length (in user coordinates) of the piecewise
+ linear or cubic curve that path 'p' represents.
+
+ 'real arctime(path p, real L);'
+ returns the path "time", a real number between 0 and the
+ length of the path in the sense of 'point(path p, real t)', at
+ which the cumulative arclength (measured from the beginning of
+ the path) equals 'L'.
+
+ 'pair arcpoint(path p, real L);'
+ returns 'point(p,arctime(p,L))'.
+
+ 'real dirtime(path p, pair z);'
+ returns the first "time", a real number between 0 and the
+ length of the path in the sense of 'point(path, real)', at
+ which the tangent to the path has the direction of pair 'z',
+ or -1 if this never happens.
+
+ 'real reltime(path p, real l);'
+ returns the time on path 'p' at the relative fraction 'l' of
+ its arclength.
+
+ 'pair relpoint(path p, real l);'
+ returns the point on path 'p' at the relative fraction 'l' of
+ its arclength.
+
+ 'pair midpoint(path p);'
+ returns the point on path 'p' at half of its arclength.
+
+ 'path reverse(path p);'
+ returns a path running backwards along 'p'.
+

+ If 'a' < 'b', the direction of the subpath is reversed.
+
+ 'path subpath(path p, real a, real b);'
+ returns the subpath of 'p' running from path time 'a' to path
+ time 'b', in the sense of 'point(path, real)'. If 'a' < 'b',
+ the direction of the subpath is reversed.
+
+ 'real[] intersect(path p, path q, real fuzz=-1);'
+ If 'p' and 'q' have at least one intersection point, return a
+ real array of length 2 containing the times representing the
+ respective path times along 'p' and 'q', in the sense of
+ 'point(path, real)', for one such intersection point (as
+ chosen by the algorithm described on page 137 of 'The
+ MetaFontbook'). The computations are performed to the
+ absolute error specified by 'fuzz', or if 'fuzz < 0', to
+ machine precision. If the paths do not intersect, return a
+ real array of length 0.
+
+ 'real[][] intersections(path p, path q, real fuzz=-1);'
+ Return all (unless there are infinitely many) intersection
+ times of paths 'p' and 'q' as a sorted array of real arrays of

+ machine precision.
+
+ 'real[] intersections(path p, explicit pair a, explicit pair b, real fuzz=-1);'
+ Return all (unless there are infinitely many) intersection
+ times of path 'p' with the (infinite) line through points 'a'
+ and 'b' as a sorted array. The intersections returned are
+ guaranteed to be correct to within the absolute error
+ specified by 'fuzz', or if 'fuzz < 0', to machine precision.
+
+ 'real[] times(path p, real x)'
+ returns all intersection times of path 'p' with the vertical
+ line through '(x,0)'.
+
+ 'real[] times(path p, explicit pair z)'
+ returns all intersection times of path 'p' with the horizontal
+ line through '(0,z.y)'.
+

+ 'p' reaches its minimal horizontal and vertical extents,
+ respectively.
+
+ 'real[] maxtimes(path p)'

+ respectively.
+
+ 'pair intersectionpoint(path p, path q, real fuzz=-1);'

+ paths 'p' and 'q'.
+
+ 'pair extension(pair P, pair Q, pair p, pair q);'
+ returns the intersection point of the extensions of the line
+ segments 'P--Q' and 'p--q', or if the lines are parallel,
+ '(infinity,infinity)'.
+
+ 'slice cut(path p, path knife, int n);'
+ returns the portions of path 'p' before and after the 'n'th
+ intersection of 'p' with path 'knife' as a structure 'slice'
+ (if no intersection exist is found, the entire path is
+ considered to be 'before' the intersection):
+ struct slice {
+ path before,after;
+ }
+ The argument 'n' is treated as modulo the number of
+ intersections.
+
+ 'slice firstcut(path p, path knife);'
+ equivalent to 'cut(p,knife,0);' Note that 'firstcut.after'
+ plays the role of the 'MetaPost cutbefore' command.
+
+ 'slice lastcut(path p, path knife);'
+ equivalent to 'cut(p,knife,-1);' Note that 'lastcut.before'
+ plays the role of the 'MetaPost cutafter' command.
+
+ 'path buildcycle(... path[] p);'
+ This returns the path surrounding a region bounded by a list
+ of two or more consecutively intersecting paths, following the
+ behaviour of the 'MetaPost buildcycle' command.
+
+ 'pair min(path p);'
+ returns the pair (left,bottom) for the path bounding box of
+ path 'p'.
+
+ 'pair max(path p);'
+ returns the pair (right,top) for the path bounding box of path
+ 'p'.
+
+ 'int windingnumber(path p, pair z);'
+ returns the winding number of the cyclic path 'p' relative to
+ the point 'z'. The winding number is positive if the path
+ encircles 'z' in the counterclockwise direction. If 'z' lies
+ on 'p' the constant 'undefined' (defined to be the largest odd
+ integer) is returned.
+
+ 'bool interior(int windingnumber, pen fillrule)'
+ returns true if 'windingnumber' corresponds to an interior
+ point according to 'fillrule'.
+
+ 'bool inside(path p, pair z, pen fillrule=currentpen);'
+ returns 'true' iff the point 'z' lies inside or on the edge of
+ the region bounded by the cyclic path 'p' according to the
+ fill rule 'fillrule' (*note fillrule::).
+
+ 'int inside(path p, path q, pen fillrule=currentpen);'
+ returns '1' if the cyclic path 'p' strictly contains 'q'
+ according to the fill rule 'fillrule' (*note fillrule::), '-1'
+ if the cyclic path 'q' strictly contains 'p', and '0'
+ otherwise.
+
+ 'pair inside(path p, pen fillrule=currentpen);'
+ returns an arbitrary point strictly inside a cyclic path 'p'
+ according to the fill rule 'fillrule' (*note fillrule::).
+
+ 'path[] strokepath(path g, pen p=currentpen);'
+ returns the path array that 'PostScript' would fill in drawing
+ path 'g' with pen 'p'.
+
+'guide'
+ an unresolved cubic spline (list of cubic-spline nodes and control
+ points). The implicit initializer for a guide is 'nullpath'; this
+ is useful for building up a guide within a loop.
+
+ A guide is similar to a path except that the computation of the
+ cubic spline is deferred until drawing time (when it is resolved
+ into a path); this allows two guides with free endpoint conditions
+ to be joined together smoothly. The solid curve in the following
+ example is built up incrementally as a guide, but only resolved at
+ drawing time; the dashed curve is incrementally resolved at each
+ iteration, before the entire set of nodes (shown in red) is known:
+
+ size(200);
+
+ real mexican(real x) {return (1-8x^2)*exp(-(4x^2));}
+
+ int n=30;
+ real a=1.5;
+ real width=2a/n;
+
+ guide hat;
+ path solved;
+
+ for(int i=0; i < n; ++i) {
+ real t=-a+i*width;
+ pair z=(t,mexican(t));
+ hat=hat..z;
+ solved=solved..z;
+ }
+
+ draw(hat);
+ dot(hat,red);
+ draw(solved,dashed);
+
+
+ [./mexicanhat]
+
+ We point out an efficiency distinction in the use of guides and
+ paths:
+ guide g;
+ for(int i=0; i < 10; ++i)
+ g=g--(i,i);
+ path p=g;
+
+ runs in linear time, whereas
+ path p;
+ for(int i=0; i < 10; ++i)
+ p=p--(i,i);
+
+ runs in quadratic time, as the entire path up to that point is
+ copied at each step of the iteration.
+
+ The following routines can be used to examine the individual
+ elements of a guide without actually resolving the guide to a fixed
+ path (except for internal cycles, which are resolved):
+
+ 'int size(guide g);'
+ Analogous to 'size(path p)'.
+
+ 'int length(guide g);'
+ Analogous to 'length(path p)'.
+
+ 'bool cyclic(path p);'
+ Analogous to 'cyclic(path p)'.
+
+ 'pair point(guide g, int t);'
+ Analogous to 'point(path p, int t)'.
+
+ 'guide reverse(guide g);'
+ Analogous to 'reverse(path p)'. If 'g' is cyclic and also
+ contains a secondary cycle, it is first solved to a path, then
+ reversed. If 'g' is not cyclic but contains an internal
+ cycle, only the internal cycle is solved before reversal. If
+ there are no internal cycles, the guide is reversed but not
+ solved to a path.
+
+ 'pair[] dirSpecifier(guide g, int i);'
+ This returns a pair array of length 2 containing the outgoing
+ (in element 0) and incoming (in element 1) direction
+ specifiers (or '(0,0)' if none specified) for the segment of
+ guide 'g' between nodes 'i' and 'i+1'.
+
+ 'pair[] controlSpecifier(guide g, int i);'
+ If the segment of guide 'g' between nodes 'i' and 'i+1' has
+ explicit outgoing and incoming control points, they are
+ returned as elements 0 and 1, respectively, of a two-element
+ array. Otherwise, an empty array is returned.
+
+ 'tensionSpecifier tensionSpecifier(guide g, int i);'
+ This returns the tension specifier for the segment of guide
+ 'g' between nodes 'i' and 'i+1'. The individual components of
+ the 'tensionSpecifier' type can be accessed as the virtual
+ members 'in', 'out', and 'atLeast'.
+
+ 'real[] curlSpecifier(guide g);'
+ This returns an array containing the initial curl specifier
+ (in element 0) and final curl specifier (in element 1) for
+ guide 'g'.
+
+ As a technical detail we note that a direction specifier given to
+ 'nullpath' modifies the node on the other side: the guides
+ a..{up}nullpath..b;
+ c..nullpath{up}..d;
+ e..{up}nullpath{down}..f;
+ are respectively equivalent to
+ a..nullpath..{up}b;
+ c{up}..nullpath..d;
+ e{down}..nullpath..{up}f;

+
+6.3 Pens
+========
+
+In 'Asymptote', pens provide a context for the four basic drawing
+commands (*note Drawing commands::). They are used to specify the
+following drawing attributes: color, line type, line width, line cap,
+line join, fill rule, text alignment, font, font size, pattern,
+overwrite mode, and calligraphic transforms on the pen nib. The default
+pen used by the drawing routines is called 'currentpen'. This provides
+the same functionality as the 'MetaPost' command 'pickup'. The implicit
+initializer for pens is 'defaultpen'.
+
+ Pens may be added together with the nonassociative binary operator
+'+'. This will add the colors of the two pens. All other non-default
+attributes of the rightmost pen will override those of the leftmost pen.
+Thus, one can obtain a yellow dashed pen by saying 'dashed+red+green' or
+'red+green+dashed' or 'red+dashed+green'. The binary operator '*' can
+be used to scale the color of a pen by a real number, until it saturates
+with one or more color components equal to 1.
+
+ * Colors are specified using one of the following colorspaces:
+ 'pen gray(real g);'
+ This produces a grayscale color, where the intensity 'g' lies
+ in the interval [0,1], with 0.0 denoting black and 1.0
+ denoting white.
+
+ 'pen rgb(real r, real g, real b);'
+ This produces an RGB color, where each of the red, green, and
+ blue intensities 'r', 'g', 'b', lies in the interval [0,1].
+
+ 'pen RGB(int r, int g, int b);'
+ This produces an RGB color, where each of the red, green, and
+ blue intensities 'r', 'g', 'b', lies in the interval [0,255].
+
+ 'pen cmyk(real c, real m, real y, real k);'
+ This produces a CMYK color, where each of the cyan, magenta,
+ yellow, and black intensities 'c', 'm', 'y', 'k', lies in the
+ interval [0,1].
+
+ 'pen invisible;'
+ This special pen writes in invisible ink, but adjusts the
+ bounding box as if something had been drawn (like the
+ '\phantom' command in TeX). The function 'bool
+ invisible(pen)' can be used to test whether a pen is
+ invisible.
+
+ The default color is 'black'; this may be changed with the routine
+ 'defaultpen(pen)'. The function 'colorspace(pen p)' returns the
+ colorspace of pen 'p' as a string ('"gray"', '"rgb"', '"cmyk"', or
+ '""').
+
+ The function 'real[] colors(pen)' returns the color components of a
+ pen. The functions 'pen gray(pen)', 'pen rgb(pen)', and 'pen
+ cmyk(pen)' return new pens obtained by converting their arguments
+ to the respective color spaces. The function
+ 'colorless(pen=currentpen)' returns a copy of its argument with the
+ color attributes stripped (to avoid color mixing).
+
+ A 6-character RGB hexadecimal string can be converted to a pen with
+ the routine
+ pen rgb(string s);
+ A pen can be converted to a hexadecimal string with
+ * string hex(pen p);
+
+ Various shades and mixtures of the grayscale primary colors 'black'
+ and 'white', RGB primary colors 'red', 'green', and 'blue', and RGB
+ secondary colors 'cyan', 'magenta', and 'yellow' are defined as
+ named colors, along with the CMYK primary colors 'Cyan', 'Magenta',
+ 'Yellow', and 'Black', in the module 'plain':
+
+ [./colors]
+
+ The standard 140 RGB 'X11' colors can be imported with the command
+ import x11colors;
+ and the standard 68 CMYK TeX colors can be imported with the
+ command
+ import texcolors;
+ Note that there is some overlap between these two standards and the
+ definitions of some colors (e.g. 'Green') actually disagree.
+
+ 'Asymptote' also comes with a 'asycolors.sty' 'LaTeX' package that
+ defines to 'LaTeX' CMYK versions of 'Asymptote''s predefined
+ colors, so that they can be used directly within 'LaTeX' strings.
+ Normally, such colors are passed to 'LaTeX' via a pen argument;
+ however, to change the color of only a portion of a string, say for
+ a slide presentation, (*note slide::) it may be desirable to
+ specify the color directly to 'LaTeX'. This file can be passed to
+ 'LaTeX' with the 'Asymptote' command
+ usepackage("asycolors");
+
+ The structure 'hsv' defined in 'plain_pens.asy' may be used to
+ convert between HSV and RGB spaces, where the hue 'h' is an angle
+ in [0,360) and the saturation 's' and value 'v' lie in '[0,1]':
+ pen p=hsv(180,0.5,0.75);
+ write(p); // ([default], red=0.375, green=0.75, blue=0.75)
+ hsv q=p;
+ write(q.h,q.s,q.v); // 180 0.5 0.75
+
+ * Line types are specified with the function 'pen linetype(real[] a,
+ real offset=0, bool scale=true, bool adjust=true)', where 'a' is an
+ array of real array numbers. The optional parameter 'offset'
+ specifies where in the pattern to begin. The first number
+ specifies how far (if 'scale' is 'true', in units of the pen line
+ width; otherwise in 'PostScript' units) to draw with the pen on,
+ the second number specifies how far to draw with the pen off, and
+ so on. If 'adjust' is 'true', these spacings are automatically
+ adjusted by 'Asymptote' to fit the arclength of the path. Here are
+ the predefined line types:
+ pen solid=linetype(new real[]);
+ pen dotted=linetype(new real[] {0,4});
+ pen dashed=linetype(new real[] {8,8});
+ pen longdashed=linetype(new real[] {24,8});
+ pen dashdotted=linetype(new real[] {8,8,0,8});
+ pen longdashdotted=linetype(new real[] {24,8,0,8});
+ pen Dotted(pen p=currentpen) {return linetype(new real[] {0,3})+2*linewidth(p);}
+ pen Dotted=Dotted();
+
+ [./linetype]
+
+ The default line type is 'solid'; this may be changed with
+ 'defaultpen(pen)'. The line type of a pen can be determined with
+ the functions 'real[] linetype(pen p=currentpen)', 'real offset(pen
+ p)', 'bool scale(pen p)', and 'bool adjust(pen p)'.
+
+ * The pen line width is specified in 'PostScript' units with 'pen
+ linewidth(real)'. The default line width is 0.5 bp; this value may
+ be changed with 'defaultpen(pen)'. The line width of a pen is
+ returned by 'real linewidth(pen p=currentpen)'. For convenience,
+ in the module 'plain_pens' we define
+ void defaultpen(real w) {defaultpen(linewidth(w));}
+ pen operator +(pen p, real w) {return p+linewidth(w);}
+ pen operator +(real w, pen p) {return linewidth(w)+p;}
+ so that one may set the line width like this:
+ defaultpen(2);
+ pen p=red+0.5;
+
+ * A pen with a specific 'PostScript' line cap is returned on calling
+ 'linecap' with an integer argument:
+ pen squarecap=linecap(0);
+ pen roundcap=linecap(1);
+ pen extendcap=linecap(2);
+
+ The default line cap, 'roundcap', may be changed with
+ 'defaultpen(pen)'. The line cap of a pen is returned by 'int
+ linecap(pen p=currentpen)'.
+
+ * A pen with a specific 'PostScript' join style is returned on
+ calling 'linejoin' with an integer argument:
+ pen miterjoin=linejoin(0);
+ pen roundjoin=linejoin(1);
+ pen beveljoin=linejoin(2);
+
+ The default join style, 'roundjoin', may be changed with
+ 'defaultpen(pen)'.The join style of a pen is returned by 'int
+ linejoin(pen p=currentpen)'.
+
+ * A pen with a specific 'PostScript' miter limit is returned by
+ calling 'miterlimit(real)'. The default miterlimit, '10.0', may be
+ changed with 'defaultpen(pen)'. The miter limit of a pen is
+ returned by 'real miterlimit(pen p=currentpen)'.
+
+ * A pen with a specific 'PostScript' fill rule is returned on calling
+ 'fillrule' with an integer argument:
+ pen zerowinding=fillrule(0);
+ pen evenodd=fillrule(1);
+
+ The fill rule, which identifies the algorithm used to determine the
+ insideness of a path or array of paths, only affects the 'clip',
+ 'fill', and 'inside' functions. For the 'zerowinding' fill rule, a
+ point 'z' is outside the region bounded by a path if the number of
+ upward intersections of the path with the horizontal line
+ 'z--z+infinity' minus the number of downward intersections is zero.
+ For the 'evenodd' fill rule, 'z' is considered to be outside the
+ region if the total number of such intersections is even. The
+ default fill rule, 'zerowinding', may be changed with
+ 'defaultpen(pen)'. The fill rule of a pen is returned by 'int
+ fillrule(pen p=currentpen)'.
+
+ * A pen with a specific text alignment setting is returned on calling
+ 'basealign' with an integer argument:
+ pen nobasealign=basealign(0);
+ pen basealign=basealign(1);
+
+ The default setting, 'nobasealign',which may be changed with
+ 'defaultpen(pen)', causes the label alignment routines to use the
+ full label bounding box for alignment. In contrast, 'basealign'
+ requests that the TeX baseline be respected. The base align
+ setting of a pen is returned by 'int basealign(pen p=currentpen)'.
+
+ * The font size is specified in TeX points (1 pt = 1/72.27 inches)
+ with the function 'pen fontsize(real size, real
+ lineskip=1.2*size)'. The default font size, 12pt, may be changed
+ with 'defaultpen(pen)'. Nonstandard font sizes may require
+ inserting
+ import fontsize;
+ at the beginning of the file (this requires the 'type1cm' package
+ available from
+ <http://mirror.ctan.org/macros/latex/contrib/type1cm/>
+ and included in recent 'LaTeX' distributions). The font size and
+ line skip of a pen can be examined with the routines 'real
+ fontsize(pen p=currentpen)' and 'real lineskip(pen p=currentpen)',
+ respectively.
+
+ * A pen using a specific LaTeX NFSS font is returned by calling the
+ function 'pen font(string encoding, string family, string series,
+ string shape)'. The default setting, 'font("OT1","cmr","m","n")',
+ corresponds to 12pt Computer Modern Roman; this may be changed with
+ 'defaultpen(pen)'. The font setting of a pen is returned by
+ 'string font(pen p=currentpen)'.
+
+ Alternatively, one may select a fixed-size TeX font (on which
+ 'fontsize' has no effect) like '"cmr12"' (12pt Computer Modern
+ Roman) or '"pcrr"' (Courier) using the function 'pen font(string
+ name)'. An optional size argument can also be given to scale the
+ font to the requested size: 'pen font(string name, real size)'.
+
+ A nonstandard font command can be generated with 'pen
+ fontcommand(string)'.
+
+ A convenient interface to the following standard 'PostScript' fonts
+ is also provided:
+ pen AvantGarde(string series="m", string shape="n");
+ pen Bookman(string series="m", string shape="n");
+ pen Courier(string series="m", string shape="n");
+ pen Helvetica(string series="m", string shape="n");
+ pen NewCenturySchoolBook(string series="m", string shape="n");
+ pen Palatino(string series="m", string shape="n");
+ pen TimesRoman(string series="m", string shape="n");
+ pen ZapfChancery(string series="m", string shape="n");
+ pen Symbol(string series="m", string shape="n");
+ pen ZapfDingbats(string series="m", string shape="n");
+
+ * Starting with the 2018/04/01 release, LaTeX takes UTF-8 as the new
+ default input encoding. However, you can still set different input
+ encoding (so as the font, font encoding or even language context).
+ Here is an example for 'cp1251' and Russian language in Cyrillic
+ script (font encoding 'T2A'):
+ texpreamble("\usepackage[math]{anttor}");
+ texpreamble("\usepackage[T2A]{fontenc}");
+ texpreamble("\usepackage[cp1251]{inputenc}");
+ texpreamble("\usepackage[russian]{babel}");
+ Support for Chinese, Japanese, and Korean fonts is provided by the
+ CJK package:
+ <https://ctan.org/pkg/cjk>
+ The following commands enable the CJK song family (within a label,
+ you can also temporarily switch to another family, say kai, by
+ prepending '"\CJKfamily{kai}"' to the label string):
+ texpreamble("\usepackage{CJK}
+ \AtBeginDocument{\begin{CJK*}{GBK}{song}}
+ \AtEndDocument{\clearpage\end{CJK*}}");
+
+ * The transparency of a pen can be changed with the command:
+ pen opacity(real opacity=1, string blend="Compatible");
+ The opacity can be varied from '0' (fully transparent) to the
+ default value of '1' (opaque), and 'blend' specifies one of the
+ following foreground-background blending operations:
+ "Compatible","Normal","Multiply","Screen","Overlay","SoftLight",
+ "HardLight","ColorDodge","ColorBurn","Darken","Lighten","Difference",
+ "Exclusion","Hue","Saturation","Color","Luminosity",
+ as described in
+ <https://www.adobe.com/content/dam/acom/en/devnet/pdf/pdfs/PDF32000_2008.pdf>.
+ Since 'PostScript' does not support transparency, this feature is
+ only effective with the '-f pdf' output format option; other
+ formats can be produced from the resulting PDF file with the
+ 'ImageMagick' 'convert' program. Labels are always drawn with an
+ 'opacity' of 1. A simple example of transparent filling is
+ provided in the example file 'transparency.asy'.
+
+ * 'PostScript' commands within a 'picture' may be used to create a
+ tiling pattern, identified by the string 'name', for 'fill' and
+ 'draw' operations by adding it to the global 'PostScript' frame
+ 'currentpatterns', with optional left-bottom margin 'lb' and
+ right-top margin 'rt'.
+ import patterns;
+ void add(string name, picture pic, pair lb=0, pair rt=0);
+
+ To 'fill' or 'draw' using pattern 'name', use the pen
+ 'pattern("name")'. For example, rectangular tilings can be
+ constructed using the routines 'picture tile(real Hx=5mm, real
+ Hy=0, pen p=currentpen, filltype filltype=NoFill)', 'picture
+ checker(real Hx=5mm, real Hy=0, pen p=currentpen)', and 'picture
+ brick(real Hx=5mm, real Hy=0, pen p=currentpen)' defined in module
+ 'patterns':
+ size(0,90);
+ import patterns;
+
+ add("tile",tile());
+ add("filledtilewithmargin",tile(6mm,4mm,red,Fill),(1mm,1mm),(1mm,1mm));
+ add("checker",checker());
+ add("brick",brick());
+
+ real s=2.5;
+ filldraw(unitcircle,pattern("tile"));
+ filldraw(shift(s,0)*unitcircle,pattern("filledtilewithmargin"));
+ filldraw(shift(2s,0)*unitcircle,pattern("checker"));
+ filldraw(shift(3s,0)*unitcircle,pattern("brick"));
+
+ [./tile]
+
+ Hatch patterns can be generated with the routines 'picture
+ hatch(real H=5mm, pair dir=NE, pen p=currentpen)', 'picture
+ crosshatch(real H=5mm, pen p=currentpen)':
+ size(0,100);
+ import patterns;
+
+ add("hatch",hatch());
+ add("hatchback",hatch(NW));
+ add("crosshatch",crosshatch(3mm));
+
+ real s=1.25;
+ filldraw(unitsquare,pattern("hatch"));
+ filldraw(shift(s,0)*unitsquare,pattern("hatchback"));
+ filldraw(shift(2s,0)*unitsquare,pattern("crosshatch"));
+
+ [./hatch]
+
+ You may need to turn off aliasing in your 'PostScript' viewer for
+ patterns to appear correctly. Custom patterns can easily be
+ constructed, following the examples in module 'patterns'. The
+ tiled pattern can even incorporate shading (*note gradient
+ shading::), as illustrated in this example (not included in the
+ manual because not all printers support 'PostScript' 3):
+ size(0,100);
+ import patterns;
+
+ real d=4mm;
+ picture tiling;
+ path square=scale(d)*unitsquare;
+ axialshade(tiling,square,white,(0,0),black,(d,d));
+ fill(tiling,shift(d,d)*square,blue);
+ add("shadedtiling",tiling);
+
+ filldraw(unitcircle,pattern("shadedtiling"));
+
+
+ * One can specify a custom pen nib as an arbitrary polygonal path
+ with 'pen makepen(path)'; this path represents the mark to be drawn
+ for paths containing a single point. This pen nib path can be
+ recovered from a pen with 'path nib(pen)'. Unlike in 'MetaPost',
+ the path need not be convex:
+
+ size(200);
+ pen convex=makepen(scale(10)*polygon(8))+grey;
+ draw((1,0.4),convex);
+ draw((0,0)---(1,1)..(2,0)--cycle,convex);
+
+ pen nonconvex=scale(10)*
+ makepen((0,0)--(0.25,-1)--(0.5,0.25)--(1,0)--(0.5,1.25)--cycle)+red;
+ draw((0.5,-1.5),nonconvex);
+ draw((0,-1.5)..(1,-0.5)..(2,-1.5),nonconvex);
+
+ [./makepen]
+
+ The value 'nullpath' represents a circular pen nib (the default);
+ an elliptical pen can be achieved simply by multiplying the pen by
+ a transform: 'yscale(2)*currentpen'.
+
+ * One can prevent labels from overwriting one another by using the
+ pen attribute 'overwrite', which takes a single argument:
+
+ 'Allow'
+ Allow labels to overwrite one another. This is the default
+ behaviour (unless overridden with 'defaultpen(pen)'.
+
+ 'Suppress'
+ Suppress, with a warning, each label that would overwrite
+ another label.
+
+ 'SuppressQuiet'
+ Suppress, without warning, each label that would overwrite
+ another label.
+
+ 'Move'
+ Move a label that would overwrite another out of the way and
+ issue a warning. As this adjustment is during the final
+ output phase (in 'PostScript' coordinates) it could result in
+ a larger figure than requested.
+
+ 'MoveQuiet'
+ Move a label that would overwrite another out of the way,
+ without warning. As this adjustment is during the final
+ output phase (in 'PostScript' coordinates) it could result in
+ a larger figure than requested.
+
+ The routine 'defaultpen()' returns the current default pen
+attributes. Calling the routine 'resetdefaultpen()' resets all pen
+default attributes to their initial values.

+
+6.4 Transforms
+==============
+
+'Asymptote' makes extensive use of affine transforms. A pair '(x,y)' is
+transformed by the transform 't=(t.x,t.y,t.xx,t.xy,t.yx,t.yy)' to
+'(x',y')', where
+x' = t.x + t.xx * x + t.xy * y
+y' = t.y + t.yx * x + t.yy * y
+This is equivalent to the 'PostScript' transformation '[t.xx t.yx t.xy
+t.yy t.x t.y]'.
+
+ Transforms can be applied to pairs, guides, paths, pens, strings,
+transforms, frames, and pictures by multiplication (via the binary
+operator '*') on the left (*note circle:: for an example). Transforms
+can be composed with one another and inverted with the function
+'transform inverse(transform t)'; they can also be raised to any integer
+power with the '^' operator.
+
+ The built-in transforms are:
+
+'transform identity;'
+ the identity transform;
+'transform shift(pair z);'
+ translates by the pair 'z';
+'transform shift(real x, real y);'
+ translates by the pair '(x,y)';
+'transform xscale(real x);'
+ scales by 'x' in the x direction;
+'transform yscale(real y);'
+ scales by 'y' in the y direction;
+'transform scale(real s);'
+ scale by 's' in both x and y directions;
+'transform scale(real x, real y);'
+ scale by 'x' in the x direction and by 'y' in the y direction;
+'transform slant(real s);'
+ maps '(x,y)' -> '(x+s*y,y)';
+'transform rotate(real angle, pair z=(0,0));'
+ rotates by 'angle' in degrees about 'z';
+'transform reflect(pair a, pair b);'
+ reflects about the line 'a--b'.
+'transform zeroTransform;'
+ the zero transform;
+
+ The implicit initializer for transforms is 'identity()'. The
+routines 'shift(transform t)' and 'shiftless(transform t)' return the
+transforms '(t.x,t.y,0,0,0,0)' and '(0,0,t.xx,t.xy,t.yx,t.yy)'
+respectively. The function 'bool isometry(transform t)' can be used to
+test if 't' is an isometry (preserves distance).
+

+
+6.5 Frames and pictures
+=======================
+
+'frame'
+ Frames are canvases for drawing in 'PostScript' coordinates. While
+ working with frames directly is occasionally necessary for
+ constructing deferred drawing routines, pictures are usually more
+ convenient to work with. The implicit initializer for frames is
+ 'newframe'. The function 'bool empty(frame f)' returns 'true' only
+ if the frame 'f' is empty. A frame may be erased with the
+ 'erase(frame)' routine. The functions 'pair min(frame)' and 'pair
+ max(frame)' return the (left,bottom) and (right,top) coordinates of
+ the frame bounding box, respectively. The contents of frame 'src'
+ may be appended to frame 'dest' with the command
+ void add(frame dest, frame src);
+ or prepended with
+ void prepend(frame dest, frame src);
+ A frame obtained by aligning frame 'f' in the direction 'align', in
+ a manner analogous to the 'align' argument of 'label' (*note
+ label::), is returned by
+ frame align(frame f, pair align);
+
+ To draw or fill a box or ellipse around a label or frame and return
+ the boundary as a path, use one of the predefined 'envelope'
+ routines
+ path box(frame f, Label L="", real xmargin=0,
+ real ymargin=xmargin, pen p=currentpen,
+ filltype filltype=NoFill, bool above=true);
+ path roundbox(frame f, Label L="", real xmargin=0,
+ real ymargin=xmargin, pen p=currentpen,
+ filltype filltype=NoFill, bool above=true);
+ path ellipse(frame f, Label L="", real xmargin=0,
+ real ymargin=xmargin, pen p=currentpen,
+ filltype filltype=NoFill, bool above=true);
+
+'picture'
+ Pictures are high-level structures (*note Structures::) defined in
+ the module 'plain' that provide canvases for drawing in user
+ coordinates. The default picture is called 'currentpicture'. A
+ new picture can be created like this:
+ picture pic;
+ Anonymous pictures can be made by the expression 'new picture'.
+
+ The 'size' routine specifies the dimensions of the desired picture:
+
+ void size(picture pic=currentpicture, real x, real y=x,
+ bool keepAspect=Aspect);
+
+ If the 'x' and 'y' sizes are both 0, user coordinates will be
+ interpreted as 'PostScript' coordinates. In this case, the
+ transform mapping 'pic' to the final output frame is 'identity()'.
+
+ If exactly one of 'x' or 'y' is 0, no size restriction is imposed
+ in that direction; it will be scaled the same as the other
+ direction.
+
+ If 'keepAspect' is set to 'Aspect' or 'true', the picture will be
+ scaled with its aspect ratio preserved such that the final width is
+ no more than 'x' and the final height is no more than 'y'.
+
+ If 'keepAspect' is set to 'IgnoreAspect' or 'false', the picture
+ will be scaled in both directions so that the final width is 'x'
+ and the height is 'y'.
+
+ To make the user coordinates of picture 'pic' represent multiples
+ of 'x' units in the x direction and 'y' units in the y direction,
+ use
+ void unitsize(picture pic=currentpicture, real x, real y=x);
+ When nonzero, these 'x' and 'y' values override the corresponding
+ size parameters of picture 'pic'.
+
+ The routine
+ void size(picture pic=currentpicture, real xsize, real ysize,
+ pair min, pair max);
+ forces the final picture scaling to map the user coordinates
+ 'box(min,max)' to a region of width 'xsize' and height 'ysize'
+ (when these parameters are nonzero).
+
+ Alternatively, calling the routine
+ transform fixedscaling(picture pic=currentpicture, pair min,
+ pair max, pen p=nullpen, bool warn=false);
+ will cause picture 'pic' to use a fixed scaling to map user
+ coordinates in 'box(min,max)' to the (already specified) picture
+ size, taking account of the width of pen 'p'. A warning will be
+ issued if the final picture exceeds the specified size.
+
+ A picture 'pic' can be fit to a frame and output to a file
+ 'prefix'.'format' using image format 'format' by calling the
+ 'shipout' function:
+ void shipout(string prefix=defaultfilename, picture pic=currentpicture,
+ orientation orientation=orientation,
+ string format="", bool wait=false, bool view=true,
+ string options="", string script="",
+ light light=currentlight, projection P=currentprojection)
+ The default output format, 'PostScript', may be changed with the
+ '-f' or '-tex' command-line options. The 'options', 'script', and
+ 'projection' parameters are only relevant for 3D pictures. If
+ 'defaultfilename' is an empty string, the prefix 'outprefix()' will
+ be used.
+
+ A 'shipout()' command is added implicitly at file exit if no
+ previous 'shipout' commands have been executed. The default page
+ orientation is 'Portrait'; this may be modified by changing the
+ variable 'orientation'. To output in landscape mode, simply set
+ the variable 'orientation=Landscape' or issue the command
+ shipout(Landscape);
+
+ To rotate the page by -90 degrees, use the orientation 'Seascape'.
+ The orientation 'UpsideDown' rotates the page by 180 degrees.
+
+ A picture 'pic' can be explicitly fit to a frame by calling
+ frame pic.fit(real xsize=pic.xsize, real ysize=pic.ysize,
+ bool keepAspect=pic.keepAspect);
+ The default size and aspect ratio settings are those given to the
+ 'size' command (which default to '0', '0', and 'true',
+ respectively). The transformation that would currently be used to
+ fit a picture 'pic' to a frame is returned by the member function
+ 'pic.calculateTransform()'.
+
+ In certain cases (e.g. 2D graphs) where only an approximate size
+ estimate for 'pic' is available, the picture fitting routine
+ frame pic.scale(real xsize=this.xsize, real ysize=this.ysize,
+ bool keepAspect=this.keepAspect);
+ (which scales the resulting frame, including labels and fixed-size
+ objects) will enforce perfect compliance with the requested size
+ specification, but should not normally be required.
+
+ To draw a bounding box with margins around a picture, fit the
+ picture to a frame using the function
+ frame bbox(picture pic=currentpicture, real xmargin=0,
+ real ymargin=xmargin, pen p=currentpen,
+ filltype filltype=NoFill);
+ Here 'filltype' specifies one of the following fill types:
+ 'FillDraw'
+ Fill the interior and draw the boundary.
+
+ 'FillDraw(real xmargin=0, real ymargin=xmargin, pen fillpen=nullpen,'
+ 'pen drawpen=nullpen)' If 'fillpen' is 'nullpen', fill with
+ the drawing pen; otherwise fill with pen 'fillpen'. If
+ 'drawpen' is 'nullpen', draw the boundary with 'fillpen';
+ otherwise with 'drawpen'. An optional margin of 'xmargin' and
+ 'ymargin' can be specified.
+
+ 'Fill'
+ Fill the interior.
+
+ 'Fill(real xmargin=0, real ymargin=xmargin, pen p=nullpen)'
+ If 'p' is 'nullpen', fill with the drawing pen; otherwise fill
+ with pen 'p'. An optional margin of 'xmargin' and 'ymargin'
+ can be specified.
+
+ 'NoFill'
+ Do not fill.
+
+ 'Draw'
+ Draw only the boundary.
+
+ 'Draw(real xmargin=0, real ymargin=xmargin, pen p=nullpen)'
+ If 'p' is 'nullpen', draw the boundary with the drawing pen;
+ otherwise draw with pen 'p'. An optional margin of 'xmargin'
+ and 'ymargin' can be specified.
+
+ 'UnFill'
+ Clip the region.
+
+ 'UnFill(real xmargin=0, real ymargin=xmargin)'
+ Clip the region and surrounding margins 'xmargin' and
+ 'ymargin'.
+
+ 'RadialShade(pen penc, pen penr)'
+ Fill varying radially from 'penc' at the center of the
+ bounding box to 'penr' at the edge.
+
+ 'RadialShadeDraw(real xmargin=0, real ymargin=xmargin, pen penc,'
+ 'pen penr, pen drawpen=nullpen)' Fill with RadialShade and
+ draw the boundary.
+
+ For example, to draw a bounding box around a picture with a 0.25 cm
+ margin and output the resulting frame, use the command:
+ shipout(bbox(0.25cm));
+ A 'picture' may be fit to a frame with the background color pen
+ 'p', using the function 'bbox(p,Fill)'.
+
+ To pad a picture to a precise size in both directions, fit the
+ picture to a frame using the function
+ frame pad(picture pic=currentpicture, real xsize=pic.xsize,
+ real ysize=pic.ysize, filltype filltype=NoFill);
+
+ The functions
+ pair min(picture pic, user=false);
+ pair max(picture pic, user=false);
+ pair size(picture pic, user=false);
+ calculate the bounds that picture 'pic' would have if it were
+ currently fit to a frame using its default size specification. If
+ 'user' is 'false' the returned value is in 'PostScript'
+ coordinates, otherwise it is in user coordinates.
+
+ The function
+ pair point(picture pic=currentpicture, pair dir, bool user=true);
+ is a convenient way of determining the point on the bounding box of
+ 'pic' in the direction 'dir' relative to its center, ignoring the
+ contributions from fixed-size objects (such as labels and
+ arrowheads). If 'user' is 'true' the returned value is in user
+ coordinates, otherwise it is in 'PostScript' coordinates.
+
+ The function
+ pair truepoint(picture pic=currentpicture, pair dir, bool user=true);
+ is identical to 'point', except that it also accounts for
+ fixed-size objects, using the scaling transform that picture 'pic'
+ would have if currently fit to a frame using its default size
+ specification. If 'user' is 'true' the returned value is in user
+ coordinates, otherwise it is in 'PostScript' coordinates.
+
+ Sometimes it is useful to draw objects on separate pictures and add
+ one picture to another using the 'add' function:
+ void add(picture src, bool group=true,
+ filltype filltype=NoFill, bool above=true);
+ void add(picture dest, picture src, bool group=true,
+ filltype filltype=NoFill, bool above=true);
+ The first example adds 'src' to 'currentpicture'; the second one
+ adds 'src' to 'dest'. The 'group' option specifies whether or not
+ the graphical user interface should treat all of the elements of
+ 'src' as a single entity (*note GUI::), 'filltype' requests
+ optional background filling or clipping, and 'above' specifies
+ whether to add 'src' above or below existing objects.
+
+ There are also routines to add a picture or frame 'src' specified
+ in postscript coordinates to another picture 'dest' (or
+ 'currentpicture') about the user coordinate 'position':
+ void add(picture src, pair position, bool group=true,
+ filltype filltype=NoFill, bool above=true);
+ void add(picture dest, picture src, pair position,
+ bool group=true, filltype filltype=NoFill, bool above=true);
+ void add(picture dest=currentpicture, frame src, pair position=0,
+ bool group=true, filltype filltype=NoFill, bool above=true);
+ void add(picture dest=currentpicture, frame src, pair position,
+ pair align, bool group=true, filltype filltype=NoFill,
+ bool above=true);
+
+ The optional 'align' argument in the last form specifies a
+ direction to use for aligning the frame, in a manner analogous to
+ the 'align' argument of 'label' (*note label::). However, one key
+ difference is that when 'align' is not specified, labels are
+ centered, whereas frames and pictures are aligned so that their
+ origin is at 'position'. Illustrations of frame alignment can be
+ found in the examples *note errorbars:: and *note image::. If you
+ want to align three or more subpictures, group them two at a time:
+
+ picture pic1;
+ real size=50;
+ size(pic1,size);
+ fill(pic1,(0,0)--(50,100)--(100,0)--cycle,red);
+
+ picture pic2;
+ size(pic2,size);
+ fill(pic2,unitcircle,green);
+

+
+ Alternatively, one can use 'attach' to automatically increase the
+ size of picture 'dest' to accommodate adding a frame 'src' about
+ the user coordinate 'position':
+ void attach(picture dest=currentpicture, frame src,
+ pair position=0, bool group=true,
+ filltype filltype=NoFill, bool above=true);
+ void attach(picture dest=currentpicture, frame src,
+ pair position, pair align, bool group=true,

+
+ To erase the contents of a picture (but not the size
+ specification), use the function
+ void erase(picture pic=currentpicture);
+
+ To save a snapshot of 'currentpicture', 'currentpen', and
+ 'currentprojection', use the function 'save()'.
+
+ To restore a snapshot of 'currentpicture', 'currentpen', and
+ 'currentprojection', use the function 'restore()'.
+
+ Many further examples of picture and frame operations are provided
+ in the base module 'plain'.
+
+ It is possible to insert verbatim 'PostScript' commands in a
+ picture with one of the routines
+ void postscript(picture pic=currentpicture, string s);
+ void postscript(picture pic=currentpicture, string s, pair min,

+ Here 'min' and 'max' can be used to specify explicit bounds
+ associated with the resulting 'PostScript' code.
+
+ Verbatim TeX commands can be inserted in the intermediate 'LaTeX'

+ void tex(picture pic=currentpicture, string s);
+ void tex(picture pic=currentpicture, string s, pair min, pair max)
+ Here 'min' and 'max' can be used to specify explicit bounds

+
+ To issue a global TeX command (such as a TeX macro definition) in

+
+ The routine

+
+6.6 Files
+=========
+
+'Asymptote' can read and write text files (including comma-separated
+value) files and portable XDR (External Data Representation) binary
+files.
+
+ An input file can be opened with
+input(string name="", bool check=true, string comment="#", string mode="");
+ reading is then done by assignment:
+file fin=input("test.txt");
+real a=fin;
+
+ If the optional boolean argument 'check' is 'false', no check will be
+made that the file exists. If the file does not exist or is not
+readable, the function 'bool error(file)' will return 'true'. The first
+character of the string 'comment' specifies a comment character. If
+this character is encountered in a data file, the remainder of the line
+is ignored. When reading strings, a comment character followed
+immediately by another comment character is treated as a single literal
+comment character. If 'Asymptote' is compiled with support for
+'libcurl', 'name' can be a URL.
+
+ Unless the '-noglobalread' command-line option is specified, one can
+change the current working directory for read operations to the contents
+of the string 's' with the function 'string cd(string s)', which returns
+the new working directory. If 'string s' is empty, the path is reset to
+the value it had at program startup.
+
+ When reading pairs, the enclosing parenthesis are optional. Strings
+are also read by assignment, by reading characters up to but not
+including a newline. In addition, 'Asymptote' provides the function
+'string getc(file)' to read the next character (treating the comment
+character as an ordinary character) and return it as a string.
+
+ A file named 'name' can be open for output with
+file output(string name="", bool update=false, string comment="#", string mode="");
+If 'update=false', any existing data in the file will be erased and only
+write operations can be used on the file. If 'update=true', any
+existing data will be preserved, the position will be set to the
+end-of-file, and both reading and writing operations will be enabled.
+For security reasons, writing to files in directories other than the
+current directory is allowed only if the '-globalwrite' (or '-nosafe')
+command-line option is specified. Reading from files in other
+directories is allowed unless the '-noglobalread' command-line option is
+specified. The function 'string mktemp(string s)' may be used to create
+and return the name of a unique temporary file in the current directory
+based on the string 's'.
+
+ There are two special files: 'stdin', which reads from the keyboard,
+and 'stdout', which writes to the terminal. The implicit initializer
+for files is 'null'.
+
+ Data of a built-in type 'T' can be written to an output file by
+calling one of the functions
+write(string s="", T x, suffix suffix=endl ... T[]);
+write(file file, string s="", T x, suffix suffix=none ... T[]);
+write(file file=stdout, string s="", explicit T[] x ... T[][]);
+write(file file=stdout, T[][]);
+write(file file=stdout, T[][][]);
+write(suffix suffix=endl);
+write(file file, suffix suffix=none);
+ If 'file' is not specified, 'stdout' is used and terminated by
+default with a newline. If specified, the optional identifying string
+'s' is written before the data 'x'. An arbitrary number of data values
+may be listed when writing scalars or one-dimensional arrays. The
+'suffix' may be one of the following: 'none' (do nothing), 'flush'
+(output buffered data), 'endl' (terminate with a newline and flush),
+'newl' (terminate with a newline), 'DOSendl' (terminate with a DOS
+newline and flush), 'DOSnewl' (terminate with a DOS newline), 'tab'
+(terminate with a tab), or 'comma' (terminate with a comma). Here are
+some simple examples of data output:
+file fout=output("test.txt");
+write(fout,1); // Writes "1"
+write(fout); // Writes a new line
+write(fout,"List: ",1,2,3); // Writes "List: 1 2 3"
+
+ A file may be opened with 'mode="xdr"', to read or write double
+precision (64-bit) reals and single precision (32-bit) integers in Sun
+Microsystem's XDR (External Data Representation) portable binary format
+(available on all 'UNIX' platforms). Alternatively, a file may also be
+opened with 'mode="binary"' to read or write double precision reals and
+single precision integers in the native (nonportable) machine binary
+format, or to read the entire file into a string. The virtual member
+functions 'file singlereal(bool b=true)' and 'file singleint(bool
+b=true)' be used to change the precision of real and integer I/O
+operations, respectively, for an XDR or binary file 'f'. Similarly, the
+function 'file signedint(bool b=true)' can be used to modify the
+signedness of integer reads and writes for an XDR or binary file 'f'.
+
+ The virtual members 'name', 'mode', 'singlereal', 'singleint', and
+'signedint' may be used to query the respective parameters for a given
+file.
+
+ One can test a file for end-of-file with the boolean function
+'eof(file)', end-of-line with 'eol(file)', and for I/O errors with
+'error(file)'. One can flush the output buffers with 'flush(file)',
+clear a previous I/O error with 'clear(file)', and close the file with
+'close(file)'. The function 'int precision(file file=stdout, int
+digits=0)' sets the number of digits of output precision for 'file' to
+'digits', provided 'digits' is nonzero, and returns the previous
+precision setting. The function 'int tell(file)' returns the current
+position in a file relative to the beginning. The routine 'seek(file
+file, int pos)' can be used to change this position, where a negative
+value for the position 'pos' is interpreted as relative to the
+end-of-file. For example, one can rewind a file 'file' with the command
+'seek(file,0)' and position to the final character in the file with
+'seek(file,-1)'. The command 'seekeof(file)' sets the position to the
+end of the file.
+
+ Assigning 'settings.scroll=n' for a positive integer 'n' requests a
+pause after every 'n' output lines to 'stdout'. One may then press
+'Enter' to continue to the next 'n' output lines, 's' followed by
+'Enter' to scroll without further interruption, or 'q' followed by
+'Enter' to quit the current output operation. If 'n' is negative, the
+output scrolls a page at a time (i.e. by one less than the current
+number of display lines). The default value, 'settings.scroll=0',
+specifies continuous scrolling.
+
+ The routines
+string getstring(string name="", string default="", string prompt="",
+ bool store=true);
+int getint(string name="", int default=0, string prompt="",
+ bool store=true);
+real getreal(string name="", real default=0, string prompt="",
+ bool store=true);
+pair getpair(string name="", pair default=0, string prompt="",
+ bool store=true);
+triple gettriple(string name="", triple default=(0,0,0), string prompt="",
+ bool store=true);
+defined in the module 'plain' may be used to prompt for a value from
+'stdin' using the GNU 'readline' library. If 'store=true', the history
+of values for 'name' is stored in the file '".asy_history_"+name' (*note
+history::). The most recent value in the history will be used to
+provide a default value for subsequent runs. The default value
+(initially 'default') is displayed after 'prompt'. These functions are
+based on the internal routines
+string readline(string prompt="", string name="", bool tabcompletion=false);
+void saveline(string name, string value, bool store=true);
+ Here, 'readline' prompts the user with the default value formatted
+according to 'prompt', while 'saveline' is used to save the string
+'value' in a local history named 'name', optionally storing the local
+history in a file '".asy_history_"+name'.
+
+ The routine 'history(string name, int n=1)' can be used to look up
+the 'n' most recent values (or all values up to 'historylines' if 'n=0')
+entered for string 'name'. The routine 'history(int n=0)' returns the
+interactive history. For example,
+write(output("transcript.asy"),history());
+outputs the interactive history to the file 'transcript.asy'.
+
+ The function 'int delete(string s)' deletes the file named by the
+string 's'. Unless the '-globalwrite' (or '-nosafe') option is enabled,
+the file must reside in the current directory. The function 'int
+rename(string from, string to)' may be used to rename file 'from' to
+file 'to'. Unless the '-globalwrite' (or '-nosafe') option is enabled,
+this operation is restricted to the current directory. The functions
+int convert(string args="", string file="", string format="");
+int animate(string args="", string file="", string format="");
+call the 'ImageMagick' commands 'convert' and 'animate', respectively,
+with the arguments 'args' and the file name constructed from the strings
+'file' and 'format'.

+
+File: asymptote.info, Node: Variable initializers, Next: Structures, Prev: Files, Up: Programming
+
+6.7 Variable initializers
+=========================
+
+A variable can be assigned a value when it is declared, as in 'int x=3;'
+where the variable 'x' is assigned the value '3'. As well as literal
+constants such as '3', arbitary expressions can be used as initializers,
+as in 'real x=2*sin(pi/2);'.
+
+ A variable is not added to the namespace until after the initializer
+is evaluated, so for example, in
+int x=2;
+int x=5*x;
+the 'x' in the initializer on the second line refers to the variable 'x'
+declared on the first line. The second line, then, declares a variable
+'x' shadowing the original 'x' and initializes it to the value '10'.
+
+ Variables of most types can be declared without an explicit
+initializer and they will be initialized by the default initializer of
+that type:
+
+ * Variables of the numeric types 'int', 'real', and 'pair' are all
+ initialized to zero; variables of type 'triple' are initialized to
+ 'O=(0,0,0)'.
+ * 'boolean' variables are initialized to 'false'.
+ * 'string' variables are initialized to the empty string.
+ * 'transform' variables are initialized to the identity
+ transformation.
+ * 'path' and 'guide' variables are initialized to 'nullpath'.
+ * 'pen' variables are initialized to the default pen.
+ * 'frame' and 'picture' variables are initialized to empty frames and
+ pictures, respectively.
+ * 'file' variables are initialized to 'null'.
+
+ The default initializers for user-defined array, structure, and
+function types are explained in their respective sections. Some types,
+such as 'code', do not have default initializers. When a variable of
+such a type is introduced, the user must initialize it by explicitly
+giving it a value.
+
+ The default initializer for any type 'T' can be redeclared by
+defining the function 'T operator init()'. For instance, 'int'
+variables are usually initialized to zero, but in
+int operator init() {
+ return 3;
+}
+int y;
+
+the variable 'y' is initialized to '3'. This example was given for
+illustrative purposes; redeclaring the initializers of built-in types is
+not recommended. Typically, 'operator init' is used to define sensible
+defaults for user-defined types.
+
+ The special type 'var' may be used to infer the type of a variable
+from its initializer. If the initializer is an expression of a unique
+type, then the variable will be defined with that type. For instance,
+var x=5;
+var y=4.3;
+var reddash=red+dashed;
+is equivalent to
+int x=5;
+real y=4.3;
+pen reddash=red+dashed;
+
+ 'var' may also be used with the extended 'for' loop syntax.
+
+int[] a = {1,2,3};
+for (var x : a)
+ write(x);
+
+
+File: asymptote.info, Node: Structures, Next: Operators, Prev: Variable initializers, Up: Programming
+
+6.8 Structures
+==============
+
+Users may also define their own data types as structures, along with
+user-defined operators, much as in C++. By default, structure members
+are 'public' (may be read and modified anywhere in the code), but may be
+optionally declared 'restricted' (readable anywhere but writeable only
+inside the structure where they are defined) or 'private' (readable and
+writable only inside the structure). In a structure definition, the
+keyword 'this' can be used as an expression to refer to the enclosing
+structure. Any code at the top-level scope within the structure is
+executed on initialization.
+
+ Variables hold references to structures. That is, in the example:
+struct T {
+ int x;
+}
+
+T foo;
+T bar=foo;
+bar.x=5;
+
+ The variable 'foo' holds a reference to an instance of the structure
+'T'. When 'bar' is assigned the value of 'foo', it too now holds a
+reference to the same instance as 'foo' does. The assignment 'bar.x=5'
+changes the value of the field 'x' in that instance, so that 'foo.x'
+will also be equal to '5'.
+
+ The expression 'new T' creates a new instance of the structure 'T'
+and returns a reference to that instance. In creating the new instance,
+any code in the body of the record definition is executed. For example:
+int Tcount=0;
+struct T {
+ int x;
+ ++Tcount;
+}
+
+T foo=new T;
+T foo;
+Here, 'new T' produces a new instance of the class, which causes
+'Tcount' to be incremented, tracking the number of instances produced.
+The declarations 'T foo=new T' and 'T foo' are equivalent: the second
+form implicitly creates a new instance of 'T'. That is, after the
+definition of a structure 'T', a variable of type 'T' is initialized to
+a new instance ('new T') by default. During the definition of the
+structure, however, variables of type 'T' are initialized to 'null' by
+default. This special behaviour is to avoid infinite recursion of
+creating new instances in code such as
+struct tree {
+ int value;
+ tree left;
+ tree right;
+}
+
+ The expression 'null' can be cast to any structure type to yield a
+null reference, a reference that does not actually refer to any instance
+of the structure. Trying to use a field of a null reference will cause
+an error.
+
+ The function 'bool alias(T,T)' checks to see if two structure
+references refer to the same instance of the structure (or both to
+'null'). In example at the beginning of this section, 'alias(foo,bar)'
+would return true, but 'alias(foo,new T)' would return false, as 'new T'
+creates a new instance of the structure 'T'. The boolean operators '=='
+and '!=' are by default equivalent to 'alias' and '!alias' respectively,
+but may be overwritten for a particular type (for example, to do a deep
+comparison).
+
+ Here is a simple example that illustrates the use of structures:
+struct S {
+ real a=1;
+ real f(real a) {return a+this.a;}
+}
+
+S s; // Initializes s with new S;
+
+write(s.f(2)); // Outputs 3
+
+S operator + (S s1, S s2)
+{
+ S result;
+ result.a=s1.a+s2.a;
+ return result;
+}
+
+write((s+s).f(0)); // Outputs 2
+
+
+ It is often convenient to have functions that construct new instances
+of a structure. Say we have a 'Person' structure:
+struct Person {
+ string firstname;
+ string lastname;
+}
+
+Person joe;
+joe.firstname="Joe";
+joe.lastname="Jones";
+Creating a new Person is a chore; it takes three lines to create a new
+instance and to initialize its fields (that's still considerably less
+effort than creating a new person in real life, though).
+
+ We can reduce the work by defining a constructor function
+'Person(string,string)':
+struct Person {
+ string firstname;
+ string lastname;
+
+ static Person Person(string firstname, string lastname) {
+ Person p=new Person;
+ p.firstname=firstname;
+ p.lastname=lastname;
+ return p;
+ }
+}
+
+Person joe=Person.Person("Joe", "Jones");
+
+ While it is now easier than before to create a new instance, we still
+have to refer to the constructor by the qualified name 'Person.Person'.
+If we add the line
+from Person unravel Person;
+immediately after the structure definition, then the constructor can be
+used without qualification: 'Person joe=Person("Joe", "Jones");'.
+
+ The constructor is now easy to use, but it is quite a hassle to
+define. If you write a lot of constructors, you will find that you are
+repeating a lot of code in each of them. Fortunately, your friendly
+neighbourhood Asymptote developers have devised a way to automate much
+of the process.
+
+ If, in the body of a structure, Asymptote encounters the definition
+of a function of the form 'void operator init(ARGS)', it implicitly
+defines a constructor function of the arguments 'ARGS' that uses the
+'void operator init' function to initialize a new instance of the
+structure. That is, it essentially defines the following constructor
+(assuming the structure is called 'Foo'):
+
+ static Foo Foo(ARGS) {
+ Foo instance=new Foo;
+ instance.operator init(ARGS);
+ return instance;
+ }
+
+ This constructor is also implicitly copied to the enclosing scope
+after the end of the structure definition, so that it can used
+subsequently without qualifying it by the structure name. Our 'Person'
+example can thus be implemented as:
+struct Person {
+ string firstname;
+ string lastname;
+
+ void operator init(string firstname, string lastname) {
+ this.firstname=firstname;
+ this.lastname=lastname;
+ }
+}
+
+Person joe=Person("Joe", "Jones");
+
+ The use of 'operator init' to implicitly define constructors should
+not be confused with its use to define default values for variables
+(*note Variable initializers::). Indeed, in the first case, the return
+type of the 'operator init' must be 'void' while in the second, it must
+be the (non-'void') type of the variable.
+
+ The function 'cputime()' returns a structure 'cputime' with
+cumulative CPU times broken down into the fields 'parent.user',
+'parent.system', 'child.user', and 'child.system', along with the
+cumulative wall clock time in 'parent.clock', all measured in seconds.
+For convenience, the incremental fields 'change.user', 'change.system',
+and 'change.clock' indicate the change in the corresponding fields since
+the last call to 'cputime()'. The function
+void write(file file=stdout, string s="", cputime c,
+ string format=cputimeformat, suffix suffix=none);
+displays the incremental user cputime followed by "u", the incremental
+system cputime followed by "s", the total user cputime followed by "U",
+and the total system cputime followed by "S".
+
+ Much like in C++, casting (*note Casts::) provides for an elegant
+implementation of structure inheritance, including virtual functions:
+struct parent {
+ real x;
+ void operator init(int x) {this.x=x;}
+ void virtual(int) {write(0);}
+ void f() {virtual(1);}
+}
+
+void write(parent p) {write(p.x);}
+
+struct child {
+ parent parent;
+ real y=3;
+ void operator init(int x) {parent.operator init(x);}
+ void virtual(int x) {write(x);}
+ parent.virtual=virtual;
+ void f()=parent.f;
+}
+
+parent operator cast(child child) {return child.parent;}
+
+parent p=parent(1);
+child c=child(2);
+
+write(c); // Outputs 2;
+
+p.f(); // Outputs 0;
+c.f(); // Outputs 1;
+
+write(c.parent.x); // Outputs 2;
+write(c.y); // Outputs 3;
+
+ For further examples of structures, see 'Legend' and 'picture' in the
+'Asymptote' base module 'plain'.

+
+6.9.1 Arithmetic & logical operators
+------------------------------------
+
+'Asymptote' uses the standard binary arithmetic operators. However,
+when one integer is divided by another, both arguments are converted to
+real values before dividing and a real quotient is returned (since this
+is typically what is intended; otherwise one can use the function 'int
+quotient(int x, int y)', which returns greatest integer less than or
+equal to 'x/y'). In all other cases both operands are promoted to the
+same type, which will also be the type of the result:
+'+'
+ addition
+'-'
+ subtraction
+'*'
+ multiplication
+'/'
+ division
+'#'
+ integer division; equivalent to 'quotient(x,y)'. Noting that the
+ 'Python3' community adopted our comment symbol ('//') for integer
+ division, we decided to reciprocate and use their comment symbol
+ for integer division in 'Asymptote'!
+'%'
+ modulo; the result always has the same sign as the divisor. In
+ particular, this makes 'q*(p # q)+p % q == p' for all integers 'p'
+ and nonzero integers 'q'.
+'^'
+ power; if the exponent (second argument) is an int, recursive
+ multiplication is used; otherwise, logarithms and exponentials are
+ used ('**' is a synonym for '^').
+
+ The usual boolean operators are also defined:
+'=='
+ equals
+'!='
+ not equals
+'<'
+ less than
+'<='
+ less than or equals
+'>='
+ greater than or equals
+'>'
+ greater than
+'&&'
+ and (with conditional evaluation of right-hand argument)
+'&'
+ and
+'||'
+ or (with conditional evaluation of right-hand argument)
+'|'
+ or
+'^'
+ xor
+'!'
+ not
+
+ 'Asymptote' also supports the C-like conditional syntax:
+bool positive=(pi > 0) ? true : false;
+
+ The function 'T interp(T a, T b, real t)' returns '(1-t)*a+t*b' for
+nonintegral built-in arithmetic types 'T'. If 'a' and 'b' are pens,
+they are first promoted to the same color space.
+
+ 'Asymptote' also defines bitwise functions 'int AND(int,int)', 'int
+OR(int,int)', 'int XOR(int,int)', 'int NOT(int)', 'int CLZ(int)' (count
+leading zeros), 'int CTZ(int)' (count trailing zeros), 'int
+popcount(int)' (count bits populated by ones), and 'int bitreverse(int
+a, int bits)' (reverse bits within a word of length bits).

+
+6.9.2 Self & prefix operators
+-----------------------------
+
+As in C, each of the arithmetic operators '+', '-', '*', '/', '#', '%',
+and '^' can be used as a self operator. The prefix operators '++'
+(increment by one) and '--' (decrement by one) are also defined. For
+example,
+int i=1;
+i += 2;
+int j=++i;
+
+is equivalent to the code
+int i=1;
+i=i+2;
+int j=i=i+1;
+
+ However, postfix operators like 'i++' and 'i--' are not defined
+(because of the inherent ambiguities that would arise with the '--'
+path-joining operator). In the rare instances where 'i++' and 'i--' are
+really needed, one can substitute the expressions '(++i-1)' and
+'(--i+1)', respectively.
+
+
+File: asymptote.info, Node: User-defined operators, Prev: Self & prefix operators, Up: Operators
+
+6.9.3 User-defined operators
+----------------------------
+
+The following symbols may be used with 'operator' to define or redefine
+operators on structures and built-in types:
+- + * / % ^ ! < > == != <= >= & | ^^ .. :: -- --- ++
+<< >> $ $$ @ @@ <>
+The operators on the second line have precedence one higher than the
+boolean operators '<', '>', '<=', and '>='.
+
+ Guide operators like '..' may be overloaded, say, to write a user
+function that produces a new guide from a given guide:
+guide dots(... guide[] g)=operator ..;
+
+guide operator ..(... guide[] g) {
+ guide G;
+ if(g.length > 0) {
+ write(g[0]);
+ G=g[0];
+ }
+ for(int i=1; i < g.length; ++i) {
+ write(g[i]);
+ write();
+ G=dots(G,g[i]);
+ }
+ return G;
+}
+
+guide g=(0,0){up}..{SW}(100,100){NE}..{curl 3}(50,50)..(10,10);

+6.11 Functions
+==============
+
+* Menu:
+
+* Default arguments:: Default values can appear anywhere
+* Named arguments:: Assigning function arguments by keyword
+* Rest arguments:: Functions with a variable number of arguments
+* Mathematical functions:: Standard libm functions
+
+'Asymptote' functions are treated as variables with a signature
+(non-function variables have null signatures). Variables with the same
+name are allowed, so long as they have distinct signatures.
+
+ Function arguments are passed by value. To pass an argument by
+reference, simply enclose it in a structure (*note Structures::).
+
+ Here are some significant features of 'Asymptote' functions:
+
+ 1. Variables with signatures (functions) and without signatures
+ (nonfunction variables) are distinct:
+ int x, x();
+ x=5;
+ x=new int() {return 17;};
+ x=x(); // calls x() and puts the result, 17, in the scalar x
+
+ 2. Traditional function definitions are allowed:
+ int sqr(int x)
+ {
+ return x*x;
+ }
+ sqr=null; // but the function is still just a variable.
+
+ 3. Casting can be used to resolve ambiguities:
+ int a, a(), b, b(); // Valid: creates four variables.
+ a=b; // Invalid: assignment is ambiguous.
+ a=(int) b; // Valid: resolves ambiguity.
+ (int) (a=b); // Valid: resolves ambiguity.
+ (int) a=b; // Invalid: cast expressions cannot be L-values.
+
+ int c();
+ c=a; // Valid: only one possible assignment.
+
+ 4. Anonymous (so-called "high-order") functions are also allowed:
+ typedef int intop(int);
+ intop adder(int m)
+ {
+ return new int(int n) {return m+n;};
+ }
+ intop addby7=adder(7);
+ write(addby7(1)); // Writes 8.
+
+ 5. One may redefine a function 'f', even for calls to 'f' in
+ previously declared functions, by assigning another (anonymous or
+ named) function to it. However, if 'f' is overloaded by a new
+ function definition, previous calls will still access the original
+ version of 'f', as illustrated in this example:
+ void f() {
+ write("hi");
+ }
+
+ void g() {
+ f();
+ }
+
+ g(); // writes "hi"
+
+ f=new void() {write("bye");};
+
+ g(); // writes "bye"
+
+ void f() {write("overloaded");};
+
+ f(); // writes "overloaded"
+ g(); // writes "bye"
+
+ 6. Anonymous functions can be used to redefine a function variable
+ that has been declared (and implicitly initialized to the null
+ function) but not yet explicitly defined:
+ void f(bool b);
+
+ void g(bool b) {
+ if(b) f(b);
+ else write(b);
+ }
+
+ f=new void(bool b) {
+ write(b);
+ g(false);
+ };
+
+ g(true); // Writes true, then writes false.
+
+ 'Asymptote' is the only language we know of that treats functions as
+variables, but allows overloading by distinguishing variables based on
+their signatures.
+
+ Functions are allowed to call themselves recursively. As in C++,
+infinite nested recursion will generate a stack overflow (reported as a
+segmentation fault, unless a fully working version of the GNU library
+'libsigsegv' (e.g. 2.4 or later) is installed at configuration time).

+
+6.11.1 Default arguments
+------------------------
+
+'Asymptote' supports a more flexible mechanism for default function
+arguments than C++: they may appear anywhere in the function prototype.
+Because certain data types are implicitly cast to more sophisticated
+types (*note Casts::) one can often avoid ambiguities by ordering
+function arguments from the simplest to the most complicated. For
+example, given
+real f(int a=1, real b=0) {return a+b;}
+then 'f(1)' returns 1.0, but 'f(1.0)' returns 2.0.
+
+ The value of a default argument is determined by evaluating the given
+'Asymptote' expression in the scope where the called function is
+defined.
+
+
+File: asymptote.info, Node: Named arguments, Next: Rest arguments, Prev: Default arguments, Up: Functions
+
+6.11.2 Named arguments
+----------------------
+
+It is sometimes difficult to remember the order in which arguments
+appear in a function declaration. Named (keyword) arguments make
+calling functions with multiple arguments easier. Unlike in the C and
+C++ languages, an assignment in a function argument is interpreted as an
+assignment to a parameter of the same name in the function signature,
+_not within the local scope_. The command-line option '-d' may be used
+to check 'Asymptote' code for cases where a named argument may be
+mistaken for a local assignment.
+
+ When matching arguments to signatures, first all of the keywords are
+matched, then the arguments without names are matched against the
+unmatched formals as usual. For example,
+int f(int x, int y) {
+ return 10x+y;
+}
+write(f(4,x=3));
+outputs 34, as 'x' is already matched when we try to match the unnamed
+argument '4', so it gets matched to the next item, 'y'.
+
+ For the rare occasions where it is desirable to assign a value to
+local variable within a function argument (generally _not_ a good
+programming practice), simply enclose the assignment in parentheses.
+For example, given the definition of 'f' in the previous example,
+int x;
+write(f(4,(x=3)));
+is equivalent to the statements
+int x;
+x=3;
+write(f(4,3));
+and outputs 43.
+
+ Parameters can be specified as "keyword-only" by putting 'keyword'
+immediately before the parameter name, as in 'int f(int keyword x)' or
+'int f(int keyword x=77)'. This forces the caller of the function to
+use a named argument to give a value for this parameter. That is,
+'f(x=42)' is legal, but 'f(25)' is not. Keyword-only parameters must be
+listed after normal parameters in a function definition.
+
+ As a technical detail, we point out that, since variables of the same
+name but different signatures are allowed in the same scope, the code
+int f(int x, int x()) {
+ return x+x();
+}
+int seven() {return 7;}
+is legal in 'Asymptote', with 'f(2,seven)' returning 9. A named
+argument matches the first unmatched formal of the same name, so
+'f(x=2,x=seven)' is an equivalent call, but 'f(x=seven,2)' is not, as
+the first argument is matched to the first formal, and 'int ()' cannot
+be implicitly cast to 'int'. Default arguments do not affect which
+formal a named argument is matched to, so if 'f' were defined as
+int f(int x=3, int x()) {
+ return x+x();
+}
+then 'f(x=seven)' would be illegal, even though 'f(seven)' obviously
+would be allowed.
+

+
+6.11.3 Rest arguments
+---------------------
+
+Rest arguments allow one to write functions that take a variable number
+of arguments:
+// This function sums its arguments.
+int sum(... int[] nums) {
+ int total=0;
+ for(int i=0; i < nums.length; ++i)
+ total += nums[i];
+ return total;
+}
+
+sum(1,2,3,4); // returns 10
+sum(); // returns 0
+
+// This function subtracts subsequent arguments from the first.
+int subtract(int start ... int[] subs) {
+ for(int i=0; i < subs.length; ++i)
+ start -= subs[i];
+ return start;
+}
+
+subtract(10,1,2); // returns 7
+subtract(10); // returns 10
+subtract(); // illegal
+
+ Putting an argument into a rest array is called _packing_. One can
+give an explicit list of arguments for the rest argument, so 'subtract'
+could alternatively be implemented as
+int subtract(int start ... int[] subs) {
+ return start - sum(... subs);
+}
+
+ One can even combine normal arguments with rest arguments:
+sum(1,2,3 ... new int[] {4,5,6}); // returns 21
+This builds a new six-element array that is passed to 'sum' as 'nums'.
+The opposite operation, _unpacking_, is not allowed:
+subtract(... new int[] {10, 1, 2});
+is illegal, as the start formal is not matched.
+
+ If no arguments are packed, then a zero-length array (as opposed to
+'null') is bound to the rest parameter. Note that default arguments are
+ignored for rest formals and the rest argument is not bound to a
+keyword.
+
+ In some cases, keyword-only parameters are helpful to avoid arguments
+intended for the rest parameter to be assigned to other parameters. For
+example, here the use of 'keyword' is to avoid 'pnorm(1.0,2.0,0.3)'
+matching '1.0' to 'p'.
+real pnorm(real keyword p=2.0 ... real[] v)
+{
+ return sum(v^p)^(1/p);
+}
+
+ The overloading resolution in 'Asymptote' is similar to the function
+matching rules used in C++. Every argument match is given a score.
+Exact matches score better than matches with casting, and matches with
+formals (regardless of casting) score better than packing an argument
+into the rest array. A candidate is maximal if all of the arguments
+score as well in it as with any other candidate. If there is one unique
+maximal candidate, it is chosen; otherwise, there is an ambiguity error.
+
+int f(path g);
+int f(guide g);
+f((0,0)--(100,100)); // matches the second; the argument is a guide
+
+int g(int x, real y);
+int g(real x, int x);
+
+g(3,4); // ambiguous; the first candidate is better for the first argument,
+ // but the second candidate is better for the second argument
+
+int h(... int[] rest);
+int h(real x ... int[] rest);
+
+h(1,2); // the second definition matches, even though there is a cast,
+ // because casting is preferred over packing
+
+int i(int x ... int[] rest);
+int i(real x, real y ... int[] rest);
+
+i(3,4); // ambiguous; the first candidate is better for the first argument,
+ // but the second candidate is better for the second one

+6.11.4 Mathematical functions
+-----------------------------
+
+'Asymptote' has built-in versions of the standard 'libm' mathematical
+real(real) functions 'sin', 'cos', 'tan', 'asin', 'acos', 'atan', 'exp',
+'log', 'pow10', 'log10', 'sinh', 'cosh', 'tanh', 'asinh', 'acosh',
+'atanh', 'sqrt', 'cbrt', 'fabs', 'expm1', 'log1p', as well as the
+identity function 'identity'. 'Asymptote' also defines the order 'n'
+Bessel functions of the first kind 'Jn(int n, real)' and second kind
+'Yn(int n, real)', as well as the gamma function 'gamma', the error
+function 'erf', and the complementary error function 'erfc'. The
+standard real(real, real) functions 'atan2', 'hypot', 'fmod',
+'remainder' are also included.
+
+ The functions 'degrees(real radians)' and 'radians(real degrees)' can
+be used to convert between radians and degrees. The function
+'Degrees(real radians)' returns the angle in degrees in the interval
+[0,360). For convenience, 'Asymptote' defines variants 'Sin', 'Cos',
+'Tan', 'aSin', 'aCos', and 'aTan' of the standard trigonometric
+functions that use degrees rather than radians. We also define complex
+versions of the 'sqrt', 'sin', 'cos', 'exp', 'log', and 'gamma'
+functions.
+
+ The functions 'floor', 'ceil', and 'round' differ from their usual
+definitions in that they all return an int value rather than a real
+(since that is normally what one wants). The functions 'Floor', 'Ceil',
+and 'Round' are respectively similar, except that if the result cannot
+be converted to a valid int, they return 'intMax' for positive arguments
+and 'intMin' for negative arguments, rather than generating an integer
+overflow. We also define a function 'sgn', which returns the sign of
+its real argument as an integer (-1, 0, or 1).
+
+ There is an 'abs(int)' function, as well as an 'abs(real)' function
+(equivalent to 'fabs(real)'), an 'abs(pair)' function (equivalent to
+'length(pair)').
+
+ Random numbers can be seeded with 'srand(int)' and generated with the
+'int rand()' function, which returns a random integer between 0 and the
+integer 'randMax'. The 'unitrand()' function returns a random number
+uniformly distributed in the interval [0,1]. A Gaussian random number
+generator 'Gaussrand' and a collection of statistics routines, including
+'histogram', are provided in the module 'stats'. The functions
+'factorial(int n)', which returns n!, and 'choose(int n, int k)', which
+returns n!/(k!(n-k)!), are also defined.
+
+ When configured with the GNU Scientific Library (GSL), available from
+<https://www.gnu.org/software/gsl/>, 'Asymptote' contains an internal
+module 'gsl' that defines the airy functions 'Ai(real)', 'Bi(real)',
+'Ai_deriv(real)', 'Bi_deriv(real)', 'zero_Ai(int)', 'zero_Bi(int)',
+'zero_Ai_deriv(int)', 'zero_Bi_deriv(int)', the Bessel functions 'I(int,
+real)', 'K(int, real)', 'j(int, real)', 'y(int, real)', 'i_scaled(int,
+real)', 'k_scaled(int, real)', 'J(real, real)', 'Y(real, real)',
+'I(real, real)', 'K(real, real)', 'zero_J(real, int)', the elliptic
+functions 'F(real, real)', 'E(real, real)', and 'P(real, real)', the
+Jacobi elliptic functions 'real[] sncndn(real,real)', the
+exponential/trigonometric integrals 'Ei', 'Si', and 'Ci', the Legendre
+polynomials 'Pl(int, real)', and the Riemann zeta function 'zeta(real)'.
+For example, to compute the sine integral 'Si' of 1.0:
+import gsl;
+write(Si(1.0));
+
+ 'Asymptote' also provides a few general purpose numerical routines:
+
+'real newton(int iterations=100, real f(real), real fprime(real), real x, bool verbose=false);'
+ Use Newton-Raphson iteration to solve for a root of a real-valued
+ differentiable function 'f', given its derivative 'fprime' and an
+ initial guess 'x'. Diagnostics for each iteration are printed if
+ 'verbose=true'. If the iteration fails after the maximum allowed
+ number of loops ('iterations'), 'realMax' is returned.
+
+'real newton(int iterations=100, real f(real), real fprime(real), real x1, real x2, bool verbose=false);'
+ Use bracketed Newton-Raphson bisection to solve for a root of a
+ real-valued differentiable function 'f' within an interval
+ ['x1','x2'] (on which the endpoint values of 'f' have opposite
+ signs), given its derivative 'fprime'. Diagnostics for each
+ iteration are printed if 'verbose=true'. If the iteration fails
+ after the maximum allowed number of loops ('iterations'), 'realMax'
+ is returned.
+
+'real simpson(real f(real), real a, real b, real acc=realEpsilon, real dxmax=b-a)'
+ returns the integral of 'f' from 'a' to 'b' using adaptive Simpson
+ integration.

+6.12 Arrays
+===========
+
+* Menu:
+
+* Slices:: Python-style array slices
+
+Appending '[]' to a built-in or user-defined type yields an array. The
+array element 'i' of an array 'A' can be accessed as 'A[i]'. By
+default, attempts to access or assign to an array element using a
+negative index generates an error. Reading an array element with an
+index beyond the length of the array also generates an error; however,
+assignment to an element beyond the length of the array causes the array
+to be resized to accommodate the new element. One can also index an
+array 'A' with an integer array 'B': the array 'A[B]' is formed by
+indexing array 'A' with successive elements of array 'B'. A convenient
+Java-style shorthand exists for iterating over all elements of an array;
+see *note array iteration::.
+
+ The declaration
+real[] A;
+
+initializes 'A' to be an empty (zero-length) array. Empty arrays should
+be distinguished from null arrays. If we say
+real[] A=null;
+
+then 'A' cannot be dereferenced at all (null arrays have no length and
+cannot be read from or assigned to).
+
+ Arrays can be explicitly initialized like this:
+real[] A={0,1,2};
+
+ Array assignment in 'Asymptote' does a shallow copy: only the pointer
+is copied (if one copy if modified, the other will be too). The 'copy'
+function listed below provides a deep copy of an array.
+
+ Every array 'A' of type 'T[]' has the virtual members
+ * 'int length',
+ * 'int cyclic',
+ * 'int[] keys',
+ * 'T push(T x)',
+ * 'void append(T[] a)',
+ * 'T pop()',
+ * 'void insert(int i ... T[] x)',
+ * 'void delete(int i, int j=i)',
+ * 'void delete()', and
+ * 'bool initialized(int n)'.
+
+ The member 'A.length' evaluates to the length of the array. Setting
+'A.cyclic=true' signifies that array indices should be reduced modulo
+the current array length. Reading from or writing to a nonempty cyclic
+array never leads to out-of-bounds errors or array resizing.
+
+ The member 'A.keys' evaluates to an array of integers containing the
+indices of initialized entries in the array in ascending order. Hence,
+for an array of length 'n' with all entries initialized, 'A.keys'
+evaluates to '{0,1,...,n-1}'. A new keys array is produced each time
+'A.keys' is evaluated.
+
+ The functions 'A.push' and 'A.append' append their arguments onto the
+end of the array, while 'A.insert(int i ... T[] x)' inserts 'x' into the
+array at index 'i'. For convenience 'A.push' returns the pushed item.
+The function 'A.pop()' pops and returns the last element, while
+'A.delete(int i, int j=i)' deletes elements with indices in the range
+['i','j'], shifting the position of all higher-indexed elements down.
+If no arguments are given, 'A.delete()' provides a convenient way of
+deleting all elements of 'A'. The routine 'A.initialized(int n)' can be
+used to examine whether the element at index 'n' is initialized. Like
+all 'Asymptote' functions, 'push', 'append', 'pop', 'insert', 'delete',
+and 'initialized' can be "pulled off" of the array and used on their
+own. For example,
+int[] A={1};
+A.push(2); // A now contains {1,2}.
+A.append(A); // A now contains {1,2,1,2}.
+int f(int)=A.push;
+f(3); // A now contains {1,2,1,2,3}.
+int g()=A.pop;
+write(g()); // Outputs 3.
+A.delete(0); // A now contains {2,1,2}.
+A.delete(0,1); // A now contains {2}.
+A.insert(1,3); // A now contains {2,3}.
+A.insert(1 ... A); // A now contains {2,2,3,3}
+A.insert(2,4,5); // A now contains {2,2,4,5,3,3}.
+
+ The '[]' suffix can also appear after the variable name; this is
+sometimes convenient for declaring a list of variables and arrays of the
+same type:
+real a,A[];
+This declares 'a' to be 'real' and implicitly declares 'A' to be of type
+'real[]'.
+
+ In the following list of built-in array functions, 'T' represents a
+generic type. Note that the internal functions 'alias', 'array',
+'copy', 'concat', 'sequence', 'map', and 'transpose', which depend on
+type 'T[]', are defined only after the first declaration of a variable
+of type 'T[]'.
+
+'new T[]'
+ returns a new empty array of type 'T[]';
+
+'new T[] {list}'
+ returns a new array of type 'T[]' initialized with 'list' (a comma
+ delimited list of elements);
+
+'new T[n]'
+ returns a new array of 'n' elements of type 'T[]'. These 'n' array
+ elements are not initialized unless they are arrays themselves (in
+ which case they are each initialized to empty arrays);
+
+'T[] array(int n, T value, int depth=intMax)'
+ returns an array consisting of 'n' copies of 'value'. If 'value'
+ is itself an array, a deep copy of 'value' is made for each entry.
+ If 'depth' is specified, this deep copying only recurses to the
+ specified number of levels;
+
+'int[] sequence(int n)'
+ if 'n >= 1' returns the array '{0,1,...,n-1}' (otherwise returns a
+ null array);
+
+'int[] sequence(int n, int m)'
+ if 'm >= n' returns an array '{n,n+1,...,m}' (otherwise returns a
+ null array);
+
+'T[] sequence(T f(int), int n)'
+ if 'n >= 1' returns the sequence '{f_i :i=0,1,...n-1}' given a
+ function 'T f(int)' and integer 'int n' (otherwise returns a null
+ array);
+
+'T[] map(T f(T), T[] a)'
+ returns the array obtained by applying the function 'f' to each
+ element of the array 'a'. This is equivalent to 'sequence(new
+ T(int i) {return f(a[i]);},a.length)';
+
+'T2[] map(T2 f(T1), T1[] a)'
+ constructed by calling 'mapArray("T1","T2")', returns the array
+ obtained by applying the function 'f' to each element of the array
+ 'a';
+
+'int[] reverse(int n)'
+ if 'n >= 1' returns the array '{n-1,n-2,...,0}' (otherwise returns
+ a null array);
+
+'int[] complement(int[] a, int n)'
+ returns the complement of the integer array 'a' in
+ '{0,1,2,...,n-1}', so that 'b[complement(a,b.length)]' yields the
+ complement of 'b[a]';
+
+'real[] uniform(real a, real b, int n)'
+ if 'n >= 1' returns a uniform partition of '[a,b]' into 'n'
+ subintervals (otherwise returns a null array);
+
+'int find(bool[] a, int n=1)'
+ returns the index of the 'n'th 'true' value in the boolean array
+ 'a' or -1 if not found. If 'n' is negative, search backwards from
+ the end of the array for the '-n'th value;
+
+'int[] findall(bool[] a)'
+ returns the indices of all 'true' values in the boolean array 'a';
+
+'int search(T[] a, T key)'
+ For built-in ordered types 'T', searches a sorted array 'a' of 'n'
+ elements for k, returning the index 'i' if 'a[i] <= key < a[i+1]',
+ '-1' if 'key' is less than all elements of 'a', or 'n-1' if 'key'
+ is greater than or equal to the last element of 'a';
+
+'int search(T[] a, T key, bool less(T i, T j))'
+ searches an array 'a' sorted in ascending order such that element
+ 'i' precedes element 'j' if 'less(i,j)' is true;
+
+'T[] copy(T[] a)'
+ returns a deep copy of the array 'a';
+
+'T[] concat(... T[][] a)'
+ returns a new array formed by concatenating the given
+ one-dimensional arrays given as arguments;
+
+'bool alias(T[] a, T[] b)'
+ returns 'true' if the arrays 'a' and 'b' are identical;
+
+'T[] sort(T[] a)'
+ For built-in ordered types 'T', returns a copy of 'a' sorted in
+ ascending order;
+
+'T[][] sort(T[][] a)'
+ For built-in ordered types 'T', returns a copy of 'a' with the rows
+ sorted by the first column, breaking ties with successively higher
+ columns. For example:
+ string[][] a={{"bob","9"},{"alice","5"},{"pete","7"},
+ {"alice","4"}};
+ // Row sort (by column 0, using column 1 to break ties):
+ write(sort(a));
+
+ produces
+ alice 4
+ alice 5
+ bob 9
+ pete 7
+
+'T[] sort(T[] a, bool less(T i, T j), bool stable=true)'
+ returns a copy of 'a' sorted in ascending order such that element
+ 'i' precedes element 'j' if 'less(i,j)' is true, subject to (if
+ 'stable' is 'true') the stability constraint that the original
+ order of elements 'i' and 'j' is preserved if 'less(i,j)' and
+ 'less(j,i)' are both 'false';
+
+'T[][] transpose(T[][] a)'
+ returns the transpose of 'a';
+
+'T[][][] transpose(T[][][] a, int[] perm)'
+ returns the 3D transpose of 'a' obtained by applying the
+ permutation 'perm' of 'new int[]{0,1,2}' to the indices of each
+ entry;
+
+'T sum(T[] a)'
+ for arithmetic types 'T', returns the sum of 'a'. In the case
+ where 'T' is 'bool', the number of true elements in 'a' is
+ returned;
+
+'T min(T[] a)'
+'T min(T[][] a)'
+'T min(T[][][] a)'
+ for built-in ordered types 'T', returns the minimum element of 'a';
+
+'T max(T[] a)'
+'T max(T[][] a)'
+'T max(T[][][] a)'
+ for built-in ordered types 'T', returns the maximum element of 'a';
+
+'T[] min(T[] a, T[] b)'
+ for built-in ordered types 'T', and arrays 'a' and 'b' of the same
+ length, returns an array composed of the minimum of the
+ corresponding elements of 'a' and 'b';
+
+'T[] max(T[] a, T[] b)'
+ for built-in ordered types 'T', and arrays 'a' and 'b' of the same
+ length, returns an array composed of the maximum of the
+ corresponding elements of 'a' and 'b';
+
+'pair[] pairs(real[] x, real[] y);'
+ for arrays 'x' and 'y' of the same length, returns the pair array
+ 'sequence(new pair(int i) {return (x[i],y[i]);},x.length)';
+
+'pair[] fft(pair[] a, int sign=1)'
+ returns the unnormalized Fast Fourier Transform of 'a' (if the
+ optional 'FFTW' package is installed), using the given 'sign'.
+ Here is a simple example:
+ int n=4;
+ pair[] f=sequence(n);
+ write(f);
+ pair[] g=fft(f,-1);
+ write();
+ write(g);
+ f=fft(g,1);
+ write();
+ write(f/n);
+
+'pair[][] fft(pair[][] a, int sign=1)'
+ returns the unnormalized two-dimensional Fourier transform of 'a'
+ using the given 'sign';
+
+'pair[][][] fft(pair[][][] a, int sign=1)'
+ returns the unnormalized three-dimensional Fourier transform of 'a'
+ using the given 'sign';
+
+'real dot(real[] a, real[] b)'
+ returns the dot product of the vectors 'a' and 'b';
+
+'pair dot(pair[] a, pair[] b)'
+ returns the complex dot product 'sum(a*conj(b))' of the vectors 'a'
+ and 'b';
+
+'real[] tridiagonal(real[] a, real[] b, real[] c, real[] f);'

+
+'real[][] solve(real[][] a, real[][] b, bool warn=true)'
+ Solve the linear equation 'a'x='b' and return the solution x, where
+ 'a' is an n \times n matrix and 'b' is an n \times m matrix. If

+
+'real[] cubicroots(real a, real b, real c, real d);'
+ This numerically robust solver returns the real roots of the cubic
+ equation ax^3+bx^2+cx+d=0. Multiple roots are listed separately.
+
+ 'Asymptote' includes a full set of vectorized array instructions for
+arithmetic (including self) and logical operations. These
+element-by-element instructions are implemented in C++ code for speed.
+Given
+real[] a={1,2};
+real[] b={3,2};
+then 'a == b' and 'a >= 2' both evaluate to the vector '{false, true}'.
+To test whether all components of 'a' and 'b' agree, use the boolean
+function 'all(a == b)'. One can also use conditionals like '(a >= 2) ?
+a : b', which returns the array '{3,2}', or 'write((a >= 2) ? a : null',
+which returns the array '{2}'.
+
+ All of the standard built-in 'libm' functions of signature
+'real(real)' also take a real array as an argument, effectively like an
+implicit call to 'map'.
+
+ As with other built-in types, arrays of the basic data types can be
+read in by assignment. In this example, the code
+file fin=input("test.txt");
+real[] A=fin;
+
+reads real values into 'A' until the end-of-file is reached (or an I/O
+error occurs).
+
+ The virtual members 'dimension', 'line', 'csv', 'word', and 'read' of
+a file are useful for reading arrays. For example, if line mode is set
+with 'file line(bool b=true)', then reading will stop once the end of
+the line is reached instead:
+file fin=input("test.txt");
+real[] A=fin.line();
+
+ Since string reads by default read up to the end of line anyway, line
+mode normally has no effect on string array reads. However, there is a
+white-space delimiter mode for reading strings, 'file word(bool
+b=true)', which causes string reads to respect white-space delimiters,
+instead of the default end-of-line delimiter:
+file fin=input("test.txt").line().word();
+real[] A=fin;
+
+ Another useful mode is comma-separated-value mode, 'file csv(bool
+b=true)', which causes reads to respect comma delimiters:
+file fin=input("test.txt").csv();
+real[] A=fin;
+
+ To restrict the number of values read, use the 'file dimension(int)'
+function:
+file fin=input("test.txt");
+real[] A=fin.dimension(10);
+
+ This reads 10 values into A, unless end-of-file (or end-of-line in
+line mode) occurs first. Attempting to read beyond the end of the file
+will produce a runtime error message. Specifying a value of 0 for the
+integer limit is equivalent to the previous example of reading until
+end-of-file (or end-of-line in line mode) is encountered.
+
+ Two- and three-dimensional arrays of the basic data types can be read
+in like this:
+file fin=input("test.txt");
+real[][] A=fin.dimension(2,3);
+real[][][] B=fin.dimension(2,3,4);
+
+ Sometimes the array dimensions are stored with the data as integer
+fields at the beginning of an array. Such 1, 2, or 3 dimensional arrays
+can be read in with the virtual member functions 'read(1)', 'read(2)',
+or 'read(3)', respectively:
+file fin=input("test.txt");
+real[] A=fin.read(1);
+real[][] B=fin.read(2);
+real[][][] C=fin.read(3);
+
+ One, two, and three-dimensional arrays of the basic data types can be
+output with the functions 'write(file,T[])', 'write(file,T[][])',
+'write(file,T[][][])', respectively.

+
+6.12.1 Slices
+-------------
+
+Asymptote allows a section of an array to be addressed as a slice using
+a Python-like syntax. If 'A' is an array, the expression 'A[m:n]'
+returns a new array consisting of the elements of 'A' with indices from
+'m' up to but not including 'n'. For example,
+int[] x={0,1,2,3,4,5,6,7,8,9};
+int[] y=x[2:6]; // y={2,3,4,5};
+int[] z=x[5:10]; // z={5,6,7,8,9};
+
+ If the left index is omitted, it is taken be '0'. If the right index
+is omitted it is taken to be the length of the array. If both are
+omitted, the slice then goes from the start of the array to the end,
+producing a non-cyclic deep copy of the array. For example:
+int[] x={0,1,2,3,4,5,6,7,8,9};
+int[] y=x[:4]; // y={0,1,2,3}
+int[] z=x[5:]; // z={5,6,7,8,9}
+int[] w=x[:]; // w={0,1,2,3,4,5,6,7,8,9}, distinct from array x.
+
+ If A is a non-cyclic array, it is illegal to use negative values for
+either of the indices. If the indices exceed the length of the array,
+however, they are politely truncated to that length.
+
+ For cyclic arrays, the slice 'A[m:n]' still consists of the cells
+with indices in the set ['m','n'), but now negative values and values
+beyond the length of the array are allowed. The indices simply wrap
+around. For example:
+
+int[] x={0,1,2,3,4,5,6,7,8,9};
+x.cyclic=true;
+int[] y=x[8:15]; // y={8,9,0,1,2,3,4}.
+int[] z=x[-5:5]; // z={5,6,7,8,9,0,1,2,3,4}
+int[] w=x[-3:17]; // w={7,8,9,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6}
+
+ Notice that with cyclic arrays, it is possible to include the same
+element of the original array multiple times within a slice. Regardless
+of the original array, arrays produced by slices are always non-cyclic.
+
+ If the left and right indices of a slice are the same, the result is
+an empty array. If the array being sliced is empty, the result is an
+empty array. Any slice with a left index greater than its right index
+will yield an error.
+
+ Slices can also be assigned to, changing the value of the original
+array. If the array being assigned to the slice has a different length
+than the slice itself, elements will be inserted or removed from the
+array to accommodate it. For instance:
+string[] toppings={"mayo", "salt", "ham", "lettuce"};
+toppings[0:2]=new string[] {"mustard", "pepper"};
+ // Now toppings={"mustard", "pepper", "ham", "lettuce"}
+toppings[2:3]=new string[] {"turkey", "bacon" };
+ // Now toppings={"mustard", "pepper", "turkey", "bacon", "lettuce"}
+toppings[0:3]=new string[] {"tomato"};
+ // Now toppings={"tomato", "bacon", "lettuce"}
+
+ If an array is assigned to a slice of itself, a copy of the original
+array is assigned to the slice. That is, code such as 'x[m:n]=x' is
+equivalent to 'x[m:n]=copy(x)'. One can use the shorthand 'x[m:m]=y' to
+insert the contents of the array 'y' into the array 'x' starting at the
+location just before 'x[m]'.
+
+ For a cyclic array, a slice is bridging if it addresses cells up to
+the end of the array and then continues on to address cells at the start
+of the array. For instance, if 'A' is a cyclic array of length 10,
+'A[8:12]', 'A[-3:1]', and 'A[5:25]' are bridging slices whereas
+'A[3:7]', 'A[7:10]', 'A[-3:0]' and 'A[103:107]' are not. Bridging
+slices can only be assigned to if the number of elements in the slice is
+exactly equal to the number of elements we are assigning to it.
+Otherwise, there is no clear way to decide which of the new entries
+should be 'A[0]' and an error is reported. Non-bridging slices may be
+assigned an array of any length.
+
+ For a cyclic array 'A' an expression of the form
+'A[A.length:A.length]' is equivalent to the expression 'A[0:0]' and so
+assigning to this slice will insert values at the start of the array.
+'A.append()' can be used to insert values at the end of the array.
+
+ It is illegal to assign to a slice of a cyclic array that repeats any
+of the cells.

+
+6.13 Casts
+==========
+
+'Asymptote' implicitly casts 'int' to 'real', 'int' to 'pair', 'real' to
+'pair', 'pair' to 'path', 'pair' to 'guide', 'path' to 'guide', 'guide'
+to 'path', 'real' to 'pen', 'pair[]' to 'guide[]', 'pair[]' to 'path[]',
+'path' to 'path[]', and 'guide' to 'path[]', along with various
+three-dimensional casts defined in module 'three'. Implicit casts are
+automatically attempted on assignment and when trying to match function
+calls with possible function signatures. Implicit casting can be
+inhibited by declaring individual arguments 'explicit' in the function
+signature, say to avoid an ambiguous function call in the following
+example, which outputs 0:
+int f(pair a) {return 0;}
+int f(explicit real x) {return 1;}
+
+write(f(0));
+
+ Other conversions, say 'real' to 'int' or 'real' to 'string', require
+an explicit cast:
+int i=(int) 2.5;
+string s=(string) 2.5;
+
+real[] a={2.5,-3.5};
+int[] b=(int []) a;
+write(stdout,b); // Outputs 2,-3
+ In situations where casting from a string to a type 'T' fails, an
+uninitialized variable is returned; this condition can be detected with
+the function 'bool initialized(T);'
+int i=(int) "2.5";
+assert(initialized(i),"Invalid cast.");
+
+real x=(real) "2.5a";
+assert(initialized(x),"Invalid cast.");
+
+ Casting to user-defined types is also possible using 'operator cast':
+struct rpair {
+ real radius;
+ real angle;
+}
+
+pair operator cast(rpair x) {
+ return (x.radius*cos(x.angle),x.radius*sin(x.angle));
+}
+
+rpair x;
+x.radius=1;
+x.angle=pi/6;
+
+write(x); // Outputs (0.866025403784439,0.5)
+
+ One must use care when defining new cast operators. Suppose that in
+some code one wants all integers to represent multiples of 100. To
+convert them to reals, one would first want to multiply them by 100.
+However, the straightforward implementation
+real operator cast(int x) {return x*100;}
+is equivalent to an infinite recursion, since the result 'x*100' needs
+itself to be cast from an integer to a real. Instead, we want to use
+the standard conversion of int to real:
+real convert(int x) {return x*100;}
+real operator cast(int x)=convert;
+
+ Explicit casts are implemented similarly, with 'operator ecast'.

+
+6.14 Import
+===========
+
+While 'Asymptote' provides many features by default, some applications
+require specialized features contained in external 'Asymptote' modules.
+For instance, the lines
+access graph;
+graph.axes();
+draw x and y axes on a two-dimensional graph. Here, the command looks
+up the module under the name 'graph' in a global dictionary of modules
+and puts it in a new variable named 'graph'. The module is a structure,
+and we can refer to its fields as we usually would with a structure.
+
+ Often, one wants to use module functions without having to specify
+the module name. The code
+from graph access axes;
+adds the 'axes' field of 'graph' into the local name space, so that
+subsequently, one can just write 'axes()'. If the given name is
+overloaded, all types and variables of that name are added. To add more
+than one name, just use a comma-separated list:
+from graph access axes, xaxis, yaxis;
+Wild card notation can be used to add all non-private fields and types
+of a module to the local name space:
+
+from graph access *;
+
+ Similarly, one can add the non-private fields and types of a
+structure to the local environment with the 'unravel' keyword:
+struct matrix {
+ real a,b,c,d;
+}
+
+real det(matrix m) {
+ unravel m;
+ return a*d-b*c;
+}
+ Alternatively, one can unravel selective fields:
+real det(matrix m) {
+ from m unravel a,b,c as C,d;
+ return a*d-b*C;
+}
+
+ The command
+import graph;
+ is a convenient abbreviation for the commands
+access graph;
+unravel graph;
+ That is, 'import graph' first loads a module into a structure called
+'graph' and then adds its non-private fields and types to the local
+environment. This way, if a member variable (or function) is
+overwritten with a local variable (or function of the same signature),
+the original one can still be accessed by qualifying it with the module
+name.
+
+ Wild card importing will work fine in most cases, but one does not
+usually know all of the internal types and variables of a module, which
+can also change as the module writer adds or changes features of the
+module. As such, it is prudent to add 'import' commands at the start of
+an 'Asymptote' file, so that imported names won't shadow locally defined
+functions. Still, imported names may shadow other imported names,
+depending on the order in which they were imported, and imported
+functions may cause overloading resolution problems if they have the
+same name as local functions defined later.
+
+ To rename modules or fields when adding them to the local
+environment, use 'as':
+access graph as graph2d;
+from graph access xaxis as xline, yaxis as yline;
+
+ The command
+import graph as graph2d;
+ is a convenient abbreviation for the commands
+access graph as graph2d;
+unravel graph2d;
+
+ Except for a few built-in modules, such as 'settings', all modules
+are implemented as 'Asymptote' files. When looking up a module that has
+not yet been loaded, 'Asymptote' searches the standard search paths
+(*note Search paths::) for the matching file. The file corresponding to
+that name is read and the code within it is interpreted as the body of a
+structure defining the module.
+
+ If the file name contains nonalphanumeric characters, enclose it with
+quotation marks:
+
+'access "/usr/local/share/asymptote/graph.asy" as graph;'
+
+'from "/usr/local/share/asymptote/graph.asy" access axes;'
+
+'import "/usr/local/share/asymptote/graph.asy" as graph;'
+
+ If 'Asymptote' is compiled with support for 'libcurl', the file name
+can even be a URL: 'import
+"https://raw.githubusercontent.com/vectorgraphics/asymptote/HEAD/doc/axis3.asy"
+as axis3;'
+
+ It is an error if modules import themselves (or each other in a
+cycle). The module name to be imported must be known at compile time.
+
+ However, you can import an 'Asymptote' module determined by the
+string 's' at runtime like this:
+eval("import "+s,true);
+
+ To conditionally execute an array of asy files, use
+void asy(string format, bool overwrite ... string[] s);
+ The file will only be processed, using output format 'format', if
+overwrite is 'true' or the output file is missing.
+
+ One can evaluate an 'Asymptote' expression (without any return value,
+however) contained in the string 's' with:
+void eval(string s, bool embedded=false);
+ It is not necessary to terminate the string 's' with a semicolon. If
+'embedded' is 'true', the string will be evaluated at the top level of
+the current environment. If 'embedded' is 'false' (the default), the
+string will be evaluated in an independent environment, sharing the same
+'settings' module (*note settings::).
+
+ One can evaluate arbitrary 'Asymptote' code (which may contain
+unescaped quotation marks) with the command
+void eval(code s, bool embedded=false);
+ Here 'code' is a special type used with 'quote {}' to enclose
+'Asymptote code' like this:
+real a=1;
+code s=quote {
+ write(a);
+};
+eval(s,true); // Outputs 1
+
+ One application of 'eval' is the creation of parametrized Asymptote
+code, such as a map from one type to another (*note map::).
+
+ To include the contents of an existing file 'graph' verbatim (as if
+the contents of the file were inserted at that point), use one of the
+forms:
+include graph;
+
+'include "/usr/local/share/asymptote/graph.asy";'
+
+ To list all global functions and variables defined in a module named
+by the contents of the string 's', use the function
+void list(string s, bool imports=false);
+Imported global functions and variables are also listed if 'imports' is
+'true'.
+
+
+File: asymptote.info, Node: Static, Prev: Import, Up: Programming
+
+6.15 Static
+===========
+
+Static qualifiers allocate the memory address of a variable in a higher
+enclosing level.
+
+ For a function body, the variable is allocated in the block where the
+function is defined; so in the code
+struct s {
+ int count() {
+ static int c=0;
+ ++c;
+ return c;
+ }
+}
+
+there is one instance of the variable 'c' for each object 's' (as
+opposed to each call of 'count').
+
+ Similarly, in
+int factorial(int n) {
+ int helper(int k) {
+ static int x=1;
+ x *= k;
+ return k == 1 ? x : helper(k-1);
+ }
+ return helper(n);
+}
+
+there is one instance of 'x' for every call to 'factorial' (and not for
+every call to 'helper'), so this is a correct, but ugly, implementation
+of factorial.
+
+ Similarly, a static variable declared within a structure is allocated
+in the block where the structure is defined. Thus,
+struct A {
+ struct B {
+ static pair z;
+ }
+}
+
+creates one object 'z' for each object of type 'A' created.
+
+ In this example,
+int pow(int n, int k) {
+ struct A {
+ static int x=1;
+ void helper() {
+ x *= n;
+ }
+ }
+ for(int i=0; i < k; ++i) {
+ A a;
+ a.helper();
+ }
+ return A.x;
+}
+
+there is one instance of 'x' for each call to 'pow', so this is an ugly
+implementation of exponentiation.
+
+ Loop constructs allocate a new frame in every iteration. This is so
+that higher-order functions can refer to variables of a specific
+iteration of a loop:
+void f();
+for(int i=0; i < 10; ++i) {
+ int x=i;
+ if(x==5) {
+ f=new void() {write(x);};
+ }
+}
+f();
+
+ Here, every iteration of the loop has its own variable 'x', so 'f()'
+will write '5'. If a variable in a loop is declared static, it will be
+allocated where the enclosing function or structure was defined (just as
+if it were declared static outside of the loop). For instance, in:
+void f() {
+ static int x;
+ for(int i=0; i < 10; ++i) {
+ static int y;
+ }
+}
+both 'x' and 'y' will be allocated in the same place, which is also
+where 'f' is allocated.
+
+ Statements may also be declared static, in which case they are run at
+the place where the enclosing function or structure is defined.
+Declarations or statements not enclosed in a function or structure
+definition are already at the top level, so static modifiers are
+meaningless. A warning is given in such a case.
+
+ Since structures can have static fields, it is not always clear for a
+qualified name whether the qualifier is a variable or a type. For
+instance, in:
+
+struct A {
+ static int x;
+}
+pair A;
+
+int y=A.x;
+does the 'A' in 'A.x' refer to the structure or to the pair variable.
+It is the convention in Asymptote that, if there is a non-function
+variable with the same name as the qualifier, the qualifier refers to
+that variable, and not to the type. This is regardless of what fields
+the variable actually possesses.

+
+7 'LaTeX' usage
+***************
+
+'Asymptote' comes with a convenient 'LaTeX' style file 'asymptote.sty'
+(v1.36 or later required) that makes 'LaTeX' 'Asymptote'-aware.
+Entering 'Asymptote' code directly into the 'LaTeX' source file, at the
+point where it is needed, keeps figures organized and avoids the need to
+invent new file names for each figure. Simply add the line
+'\usepackage{asymptote}' at the beginning of your file and enclose your
+'Asymptote' code within a '\begin{asy}...\end{asy}' environment. As
+with the 'LaTeX' 'comment' environment, the '\end{asy}' command must
+appear on a line by itself, with no trailing commands/comments. A blank
+line is not allowed after '\begin{asy}'.
+
+ The sample 'LaTeX' file below, named 'latexusage.tex', can be run as
+follows:
+latex latexusage
+asy latexusage-*.asy
+latex latexusage
+
+or
+pdflatex latexusage
+asy latexusage-*.asy
+pdflatex latexusage
+To switch between using inline Asymptote code with 'latex' and
+'pdflatex' you may first need to remove the files 'latexusage-*.tex'.
+
+ An even better method for processing a 'LaTeX' file with embedded
+'Asymptote' code is to use the 'latexmk' utility from
+ <http://mirror.ctan.org/support/latexmk/>
+after putting the contents of
+<https://raw.githubusercontent.com/vectorgraphics/asymptote/HEAD/doc/latexmkrc>
+in a file 'latexmkrc' in the same directory. The command
+latexmk -pdf latexusage
+will then call 'Asymptote' automatically, recompiling only the figures
+that have changed. Since each figure is compiled in a separate system
+process, this method also tends to use less memory. To store the
+figures in a separate directory named 'asy', one can define
+\def\asydir{asy}
+ in 'latexusage.tex' and put the contents of
+<https://raw.githubusercontent.com/vectorgraphics/asymptote/HEAD/doc/latexmkrc_asydir>
+in a file 'latexmkrc' in the same directory. External 'Asymptote' code
+can be included with
+\asyinclude[<options>]{<filename.asy>}
+so that 'latexmk' will recognize when the code is changed. Note that
+'latemk' requires 'perl', available from <https://www.perl.org/>.
+
+ One can specify 'width', 'height', 'keepAspect', 'viewportwidth',
+'viewportheight', 'attach', and 'inline'. 'keyval'-style options to the
+'asy' and 'asyinclude' environments. Three-dimensional PRC files may
+either be embedded within the page (the default) or attached as
+annotated (but printable) attachments, using the 'attach' option and the
+'attachfile2' (or older 'attachfile') 'LaTeX' package. The 'inline'
+option generates inline 'LaTeX' code instead of EPS or PDF files. This
+makes 2D LaTeX symbols visible to the '\begin{asy}...\end{asy}'
+environment. In this mode, Asymptote correctly aligns 2D LaTeX symbols
+defined outside of '\begin{asy}...\end{asy}', but treats their size as
+zero; an optional second string can be given to 'Label' to provide an
+estimate of the unknown label size.
+
+ Note that if the 'latex' TeX engine is used with the 'inline' option,
+labels might not show up in DVI viewers that cannot handle raw
+'PostScript' code. One can use 'dvips'/'dvipdf' to produce
+'PostScript'/PDF output (we recommend using the modified version of
+'dvipdf' in the 'Asymptote' patches directory, which accepts the 'dvips
+-z' hyperdvi option).
+

+
+8.1 'plain'
+===========
+
+This is the default 'Asymptote' base file, which defines key parts of
+the drawing language (such as the 'picture' structure).
+
+ By default, an implicit 'private import plain;' occurs before
+translating a file and before the first command given in interactive
+mode. This also applies when translating files for module definitions
+(except when translating 'plain', of course). This means that the types
+and functions defined in 'plain' are accessible in almost all
+'Asymptote' code. Use the '-noautoplain' command-line option to disable
+this feature.
+
+
+File: asymptote.info, Node: simplex, Next: math, Prev: plain, Up: Base modules
+
+8.2 'simplex'
+=============
+
+This module solves the two-variable linear programming problem using the

+
+8.3 'math'
+==========
+
+This module extends 'Asymptote''s mathematical capabilities with useful
+functions such as
+
+'void drawline(picture pic=currentpicture, pair P, pair Q, pen p=currentpen);'
+ draw the visible portion of the (infinite) line going through 'P'
+ and 'Q', without altering the size of picture 'pic', using pen 'p'.
+
+'real intersect(triple P, triple Q, triple n, triple Z);'
+ returns the intersection time of the extension of the line segment
+ 'PQ' with the plane perpendicular to 'n' and passing through 'Z'.
+
+'triple intersectionpoint(triple n0, triple P0, triple n1, triple P1);'
+ Return any point on the intersection of the two planes with normals
+ 'n0' and 'n1' passing through points 'P0' and 'P1', respectively.

+'real[] partialsum(real[] a, real[] dx)'
+ returns the partial 'dx'-weighted sums of a real array 'a'.
+
+'bool increasing(real[] a, bool strict=false)'
+ returns, if 'strict=false', whether 'i > j' implies 'a[i] >= a[j]',
+ or if 'strict=true', whether 'i > j' implies implies 'a[i] > a[j]'.
+
+'int unique(real[] a, real x)'
+ if the sorted array 'a' does not contain 'x', insert it
+ sequentially, returning the index of 'x' in the resulting array.
+

+
+8.4 'interpolate'
+=================
+
+This module implements Lagrange, Hermite, and standard cubic spline
+interpolation in 'Asymptote', as illustrated in the example
+'interpolate1.asy'.
+
+
+File: asymptote.info, Node: geometry, Next: trembling, Prev: interpolate, Up: Base modules
+
+8.5 'geometry'
+==============
+
+This module, written by Philippe Ivaldi, provides an extensive set of
+geometry routines, including 'perpendicular' symbols and a 'triangle'
+structure. Link to the documentation for the 'geometry' module are
+posted here: <https://asymptote.sourceforge.io/links.html>, including an
+extensive set of examples,
+<http://www.piprime.fr/files/asymptote/geometry/>, and an index:
+ <http://www.piprime.fr/files/asymptote/geometry/modules/geometry.asy.index.type.html>
+
+
+File: asymptote.info, Node: trembling, Next: stats, Prev: geometry, Up: Base modules
+
+8.6 'trembling'
+===============
+
+This module, written by Philippe Ivaldi and illustrated in the example
+'floatingdisk.asy', allows one to draw wavy lines, as if drawn by hand.
+
+
+File: asymptote.info, Node: stats, Next: patterns, Prev: trembling, Up: Base modules
+
+8.7 'stats'
+===========
+
+This module implements a Gaussian random number generator and a
+collection of statistics routines, including 'histogram' and
+'leastsquares'.
+
+
+File: asymptote.info, Node: patterns, Next: markers, Prev: stats, Up: Base modules
+
+8.8 'patterns'
+==============
+
+This module implements 'PostScript' tiling patterns and includes several
+convenient pattern generation routines.
+
+
+File: asymptote.info, Node: markers, Next: tree, Prev: patterns, Up: Base modules
+
+8.9 'markers'
+=============
+
+This module implements specialized routines for marking paths and
+angles. The principal mark routine provided by this module is
+markroutine markinterval(int n=1, frame f, bool rotated=false);
+which centers 'n' copies of frame 'f' within uniformly space intervals
+in arclength along the path, optionally rotated by the angle of the
+local tangent.
+
+ The 'marker' (*note marker::) routine can be used to construct new
+markers from these predefined frames:
+
+frame stickframe(int n=1, real size=0, pair space=0, real angle=0,
+ pair offset=0, pen p=currentpen);
+frame circlebarframe(int n=1, real barsize=0,
+ real radius=0,real angle=0,
+ pair offset=0, pen p=currentpen,
+ filltype filltype=NoFill, bool above=false);
+frame crossframe(int n=3, real size=0, pair space=0,
+ real angle=0, pair offset=0, pen p=currentpen);
+frame tildeframe(int n=1, real size=0, pair space=0,
+ real angle=0, pair offset=0, pen p=currentpen);
+
+ For convenience, this module also constructs the markers
+'StickIntervalMarker', 'CrossIntervalMarker', 'CircleBarIntervalMarker',
+and 'TildeIntervalMarker' from the above frames. The example
+'markers1.asy' illustrates the use of these markers:
+
+
+ [./markers1]
+
+ This module also provides a routine for marking an angle AOB:
+void markangle(picture pic=currentpicture, Label L="",
+ int n=1, real radius=0, real space=0,
+ pair A, pair O, pair B, arrowbar arrow=None,
+ pen p=currentpen, margin margin=NoMargin,
+ marker marker=nomarker);
+as illustrated in the example 'markers2.asy'.
+
+
+ [./markers2]
+
+
+File: asymptote.info, Node: map, Next: tree, Prev: markers, Up: Base modules
+
+8.10 'map'
+==========
+
+This module creates a struct parameterized by the types specified in
+strings 'key' and 'value', mapping keys to values with a specified
+default:
+import map;
+
+mapTemplate(name="map",key="string",value="int",default="-1");
+
+map M;
+
+M.add("z",2);
+M.add("a",3);
+M.add("d",4);
+write(M.lookup("a"));
+write(M.lookup("y"));
+
+
+File: asymptote.info, Node: tree, Next: binarytree, Prev: markers, Up: Base modules
+
+8.11 'tree'
+===========
+
+This module implements an example of a dynamic binary search tree.
+
+
+File: asymptote.info, Node: binarytree, Next: drawtree, Prev: tree, Up: Base modules
+
+8.12 'binarytree'
+=================
+
+This module can be used to draw an arbitrary binary tree and includes an
+input routine for the special case of a binary search tree, as
+illustrated in the example 'binarytreetest.asy':
+import binarytree;
+
+picture pic,pic2;
+
+binarytree bt=binarytree(1,2,4,nil,5,nil,nil,0,nil,nil,3,6,nil,nil,7);
+draw(pic,bt,condensed=false);
+
+binarytree st=searchtree(10,5,2,1,3,4,7,6,8,9,15,13,12,11,14,17,16,18,19);
+draw(pic2,st,blue,condensed=true);
+
+add(pic.fit(),(0,0),10N);
+add(pic2.fit(),(0,0),10S);
+
+
+ [./binarytreetest]
+
+
+File: asymptote.info, Node: drawtree, Next: syzygy, Prev: binarytree, Up: Base modules
+
+8.13 'drawtree'
+===============
+
+This is a simple tree drawing module used by the example 'treetest.asy'.
+
+
+File: asymptote.info, Node: syzygy, Next: feynman, Prev: drawtree, Up: Base modules
+
+8.14 'syzygy'
+=============
+
+This module automates the drawing of braids, relations, and syzygies,
+along with the corresponding equations, as illustrated in the example
+'knots.asy'.
+
+
+File: asymptote.info, Node: feynman, Next: roundedpath, Prev: syzygy, Up: Base modules
+
+8.15 'feynman'
+==============
+
+This module, contributed by Martin Wiebusch, is useful for drawing
+Feynman diagrams, as illustrated by the examples 'eetomumu.asy' and
+'fermi.asy'.
+
+
+File: asymptote.info, Node: roundedpath, Next: animation, Prev: feynman, Up: Base modules
+
+8.16 'roundedpath'
+==================
+
+This module, contributed by Stefan Knorr, is useful for rounding the
+sharp corners of paths, as illustrated in the example file
+'roundpath.asy'.
+
+
+File: asymptote.info, Node: animation, Next: embed, Prev: roundedpath, Up: Base modules
+
+8.17 'animation'
+================
+
+This module allows one to generate animations, as illustrated by the
+files 'wheel.asy', 'wavepacket.asy', and 'cube.asy' in the 'animations'
+subdirectory of the examples directory. These animations use the
+'ImageMagick' 'convert' program to merge multiple images into a GIF or
+MPEG movie.
+
+ The related 'animate' module, derived from the 'animation' module,
+generates higher-quality portable clickable PDF movies, with optional
+controls. This requires installing the module
+ <http://mirror.ctan.org/macros/latex/contrib/animate/animate.sty>
+(version 2007/11/30 or later) in a new directory 'animate' in the local
+'LaTeX' directory (for example, in
+'/usr/local/share/texmf/tex/latex/animate'). On 'UNIX' systems, one
+must then execute the command 'texhash'.
+
+ The example 'pdfmovie.asy' in the 'animations' directory, along with
+the slide presentations 'slidemovies.asy' and 'intro', illustrate the
+use of embedded PDF movies. The examples 'inlinemovie.tex' and
+'inlinemovie3.tex' show how to generate and embed PDF movies directly
+within a 'LaTeX' file (*note LaTeX usage::). The member function
+string pdf(fit fit=NoBox, real delay=animationdelay, string options="",
+ bool keep=settings.keep, bool multipage=true);
+of the 'animate' structure accepts any of the 'animate.sty' options, as
+described here:
+ <http://mirror.ctan.org/macros/latex/contrib/animate/doc/animate.pdf>
+
+
+File: asymptote.info, Node: embed, Next: slide, Prev: animation, Up: Base modules
+
+8.18 'embed'
+============
+
+This module provides an interface to the 'LaTeX' package (included with
+'MikTeX')
+ <http://mirror.ctan.org/macros/latex/contrib/media9>
+for embedding movies, sounds, and 3D objects into a PDF document.
+
+ A more portable method for embedding movie files, which should work
+on any platform and does not require the 'media9' package, is provided
+by using the 'external' module instead of 'embed'.
+
+ Examples of the above two interfaces is provided in the file
+'embeddedmovie.asy' in the 'animations' subdirectory of the examples
+directory and in 'externalmovie.asy'. For a higher quality embedded
+movie generated directly by 'Asymptote', use the 'animate' module along
+with the 'animate.sty' package to embed a portable PDF animation (*note
+animate::).
+
+ An example of embedding 'U3D' code is provided in the file
+'embeddedu3d'.
+
+
+File: asymptote.info, Node: slide, Next: MetaPost, Prev: embed, Up: Base modules
+
+8.19 'slide'
+============
+
+This module provides a simple yet high-quality facility for making
+presentation slides, including portable embedded PDF animations (see the
+file 'slidemovies.asy'). A simple example is provided in
+'slidedemo.asy'.
+
+
+File: asymptote.info, Node: MetaPost, Next: babel, Prev: slide, Up: Base modules
+
+8.20 'MetaPost'
+===============
+
+This module provides some useful routines to help 'MetaPost' users
+migrate old 'MetaPost' code to 'Asymptote'. Further contributions here
+are welcome.
+
+ Unlike 'MetaPost', 'Asymptote' does not implicitly solve linear
+equations and therefore does not have the notion of a 'whatever'
+unknown. The routine 'extension' (*note extension::) provides a useful
+replacement for a common use of 'whatever': finding the intersection
+point of the lines through 'P', 'Q' and 'p', 'q'. For less common
+occurrences of 'whatever', one can use the built-in explicit linear
+equation solver 'solve' instead.
+
+
+File: asymptote.info, Node: babel, Next: labelpath, Prev: MetaPost, Up: Base modules
+
+8.21 'babel'
+============
+
+This module implements the 'LaTeX' 'babel' package in 'Asymptote'. For
+example:
+import babel;
+babel("german");
+
+
+File: asymptote.info, Node: labelpath, Next: labelpath3, Prev: babel, Up: Base modules
+
+8.22 'labelpath'
+================
+
+This module uses the 'PSTricks' 'pstextpath' macro to fit labels along a
+path (properly kerned, as illustrated in the example file
+'curvedlabel.asy'), using the command
+void labelpath(picture pic=currentpicture, Label L, path g,
+ string justify=Centered, pen p=currentpen);
+Here 'justify' is one of 'LeftJustified', 'Centered', or
+'RightJustified'. The x component of a shift transform applied to the
+Label is interpreted as a shift along the curve, whereas the y component
+is interpreted as a shift away from the curve. All other Label
+transforms are ignored. This module requires the 'latex' tex engine and
+inherits the limitations of the 'PSTricks' '\pstextpath' macro.
+
+
+File: asymptote.info, Node: labelpath3, Next: annotate, Prev: labelpath, Up: Base modules
+
+8.23 'labelpath3'
+=================
+
+This module, contributed by Jens Schwaiger, implements a 3D version of
+'labelpath' that does not require the 'PSTricks' package. An example is
+provided in 'curvedlabel3.asy'.
+
+
+File: asymptote.info, Node: annotate, Next: CAD, Prev: labelpath3, Up: Base modules
+
+8.24 'annotate'
+===============
+
+This module supports PDF annotations for viewing with 'Adobe Reader',
+via the function
+void annotate(picture pic=currentpicture, string title, string text,
+ pair position);
+Annotations are illustrated in the example file 'annotation.asy'.
+Currently, annotations are only implemented for the 'latex' (default)
+and 'tex' TeX engines.
+
+
+File: asymptote.info, Node: CAD, Next: graph, Prev: annotate, Up: Base modules
+
+8.25 'CAD'
+==========
+
+This module, contributed by Mark Henning, provides basic pen definitions
+and measurement functions for simple 2D CAD drawings according to DIN
+15. It is documented separately, in the file 'CAD.pdf'.
+
+
+File: asymptote.info, Node: graph, Next: palette, Prev: CAD, Up: Base modules
+
+8.26 'graph'
+============
+
+This module implements two-dimensional linear and logarithmic graphs,
+including automatic scale and tick selection (with the ability to
+override manually). A graph is a 'guide' (that can be drawn with the
+draw command, with an optional legend) constructed with one of the
+following routines:
+
+ * guide graph(picture pic=currentpicture, real f(real), real a, real b,
+ int n=ngraph, real T(real)=identity,
+ interpolate join=operator --);
+ guide[] graph(picture pic=currentpicture, real f(real), real a, real b,
+ int n=ngraph, real T(real)=identity, bool3 cond(real),
+ interpolate join=operator --);
+
+ Returns a graph using the scaling information for picture 'pic'
+ (*note automatic scaling::) of the function 'f' on the interval
+ ['T'('a'),'T'('b')], sampling at 'n' points evenly spaced in
+ ['a','b'], optionally restricted by the bool3 function 'cond' on
+ ['a','b']. If 'cond' is:
+ * 'true', the point is added to the existing guide;
+ * 'default', the point is added to a new guide;
+ * 'false', the point is omitted and a new guide is begun.
+ The points are connected using the interpolation specified by
+ 'join':
+
+ * 'operator --' (linear interpolation; the abbreviation
+ 'Straight' is also accepted);
+
+ * 'operator ..' (piecewise Bezier cubic spline interpolation;
+ the abbreviation 'Spline' is also accepted);
+
+ * 'Hermite' (standard cubic spline interpolation using boundary
+ condition 'notaknot', 'natural', 'periodic', 'clamped(real
+ slopea, real slopeb)'), or 'monotonic'. The abbreviation
+ 'Hermite' is equivalent to 'Hermite(notaknot)' for nonperiodic
+ data and 'Hermite(periodic)' for periodic data).
+
+ * guide graph(picture pic=currentpicture, real x(real), real y(real),
+ real a, real b, int n=ngraph, real T(real)=identity,
+ interpolate join=operator --);
+ guide[] graph(picture pic=currentpicture, real x(real), real y(real),
+ real a, real b, int n=ngraph, real T(real)=identity,
+ bool3 cond(real), interpolate join=operator --);
+
+ Returns a graph using the scaling information for picture 'pic' of
+ the parametrized function ('x'(t),'y'(t)) for t in the interval
+ ['T'('a'),'T'('b')], sampling at 'n' points evenly spaced in
+ ['a','b'], optionally restricted by the bool3 function 'cond' on
+ ['a','b'], using the given interpolation type.
+
+ * guide graph(picture pic=currentpicture, pair z(real), real a, real b,
+ int n=ngraph, real T(real)=identity,
+ interpolate join=operator --);
+ guide[] graph(picture pic=currentpicture, pair z(real), real a, real b,
+ int n=ngraph, real T(real)=identity, bool3 cond(real),
+ interpolate join=operator --);
+
+ Returns a graph using the scaling information for picture 'pic' of
+ the parametrized function 'z'(t) for t in the interval
+ ['T'('a'),'T'('b')], sampling at 'n' points evenly spaced in
+ ['a','b'], optionally restricted by the bool3 function 'cond' on
+ ['a','b'], using the given interpolation type.
+
+ * guide graph(picture pic=currentpicture, pair[] z,
+ interpolate join=operator --);
+ guide[] graph(picture pic=currentpicture, pair[] z, bool3[] cond,
+ interpolate join=operator --);
+
+ Returns a graph using the scaling information for picture 'pic' of
+ the elements of the array 'z', optionally restricted to those
+ indices for which the elements of the boolean array 'cond' are
+ 'true', using the given interpolation type.
+
+ * guide graph(picture pic=currentpicture, real[] x, real[] y,
+ interpolate join=operator --);
+ guide[] graph(picture pic=currentpicture, real[] x, real[] y,
+ bool3[] cond, interpolate join=operator --);
+
+ Returns a graph using the scaling information for picture 'pic' of
+ the elements of the arrays ('x','y'), optionally restricted to
+ those indices for which the elements of the boolean array 'cond'
+ are 'true', using the given interpolation type.
+
+ * guide polargraph(picture pic=currentpicture, real f(real), real a,
+ real b, int n=ngraph, interpolate join=operator --);
+
+ Returns a polar-coordinate graph using the scaling information for
+ picture 'pic' of the function 'f' on the interval ['a','b'],
+ sampling at 'n' evenly spaced points, with the given interpolation
+ type.
+
+ * guide polargraph(picture pic=currentpicture, real[] r, real[] theta,
+ interpolate join=operator--);
+ Returns a polar-coordinate graph using the scaling information for
+ picture 'pic' of the elements of the arrays ('r','theta'), using
+ the given interpolation type.
+
+
+
+
+ An axis can be drawn on a picture with one of the following commands:
+
+ * void xaxis(picture pic=currentpicture, Label L="", axis axis=YZero,
+ real xmin=-infinity, real xmax=infinity, pen p=currentpen,
+ ticks ticks=NoTicks, arrowbar arrow=None, bool above=false);
+
+ Draw an x axis on picture 'pic' from x='xmin' to x='xmax' using pen
+ 'p', optionally labelling it with Label 'L'. The relative label
+ location along the axis (a real number from [0,1]) defaults to 1
+ (*note Label::), so that the label is drawn at the end of the axis.
+ An infinite value of 'xmin' or 'xmax' specifies that the
+ corresponding axis limit will be automatically determined from the
+ picture limits. The optional 'arrow' argument takes the same
+ values as in the 'draw' command (*note arrows::). The axis is
+ drawn before any existing objects in 'pic' unless 'above=true'.
+ The axis placement is determined by one of the following 'axis'
+ types:
+
+ 'YZero(bool extend=true)'
+ Request an x axis at y=0 (or y=1 on a logarithmic axis)
+ extending to the full dimensions of the picture, unless
+ 'extend'=false.
+
+ 'YEquals(real Y, bool extend=true)'
+ Request an x axis at y='Y' extending to the full dimensions of
+ the picture, unless 'extend'=false.
+
+ 'Bottom(bool extend=false)'
+ Request a bottom axis.
+
+ 'Top(bool extend=false)'
+ Request a top axis.
+
+ 'BottomTop(bool extend=false)'
+ Request a bottom and top axis.
+
+ Custom axis types can be created by following the examples in the
+ module 'graph.asy'. One can easily override the default values for
+ the standard axis types:
+ import graph;
+
+ YZero=new axis(bool extend=true) {
+ return new void(picture pic, axisT axis) {
+ real y=pic.scale.x.scale.logarithmic ? 1 : 0;
+ axis.value=I*pic.scale.y.T(y);
+ axis.position=1;
+ axis.side=right;
+ axis.align=2.5E;
+ axis.value2=Infinity;
+ axis.extend=extend;
+ };
+ };
+ YZero=YZero();
+
+
+ The default tick option is 'NoTicks'. The options 'LeftTicks',
+ 'RightTicks', or 'Ticks' can be used to draw ticks on the left,
+ right, or both sides of the path, relative to the direction in
+ which the path is drawn. These tick routines accept a number of
+ optional arguments:
+ ticks LeftTicks(Label format="", ticklabel ticklabel=null,
+ bool beginlabel=true, bool endlabel=true,
+ int N=0, int n=0, real Step=0, real step=0,
+ bool begin=true, bool end=true, tickmodifier modify=None,
+ real Size=0, real size=0, bool extend=false,
+ pen pTick=nullpen, pen ptick=nullpen);
+
+ If any of these parameters are omitted, reasonable defaults will be
+ chosen:
+ 'Label format'
+ override the default tick label format ('defaultformat',
+ initially "$%.4g$"), rotation, pen, and alignment (for
+ example, 'LeftSide', 'Center', or 'RightSide') relative to the
+ axis. To enable 'LaTeX' math mode fonts, the format string
+ should begin and end with '$' *note format::. If the format
+ string is 'trailingzero', trailing zeros will be added to the
+ tick labels; if the format string is '"%"', the tick label
+ will be suppressed;
+ 'ticklabel'
+ is a function 'string(real x)' returning the label (by
+ default, format(format.s,x)) for each major tick value 'x';
+ 'bool beginlabel'
+ include the first label;
+ 'bool endlabel'
+ include the last label;
+ 'int N'
+ when automatic scaling is enabled (the default; *note
+ automatic scaling::), divide a linear axis evenly into this
+ many intervals, separated by major ticks; for a logarithmic
+ axis, this is the number of decades between labelled ticks;
+ 'int n'
+ divide each interval into this many subintervals, separated by
+ minor ticks;
+ 'real Step'
+ the tick value spacing between major ticks (if 'N'='0');
+ 'real step'
+ the tick value spacing between minor ticks (if 'n'='0');
+ 'bool begin'
+ include the first major tick;
+ 'bool end'
+ include the last major tick;
+ 'tickmodifier modify;'
+ an optional function that takes and returns a 'tickvalue'
+ structure having real[] members 'major' and 'minor' consisting
+ of the tick values (to allow modification of the automatically
+ generated tick values);
+ 'real Size'
+ the size of the major ticks (in 'PostScript' coordinates);
+ 'real size'
+ the size of the minor ticks (in 'PostScript' coordinates);
+ 'bool extend;'
+ extend the ticks between two axes (useful for drawing a grid
+ on the graph);
+ 'pen pTick'
+ an optional pen used to draw the major ticks;
+ 'pen ptick'
+ an optional pen used to draw the minor ticks.
+
+ For convenience, the predefined tickmodifiers 'OmitTick(... real[]
+ x)', 'OmitTickInterval(real a, real b)', and
+ 'OmitTickIntervals(real[] a, real[] b)' can be used to remove
+ specific auto-generated ticks and their labels. The
+ 'OmitFormat(string s=defaultformat ... real[] x)' ticklabel can be
+ used to remove specific tick labels but not the corresponding
+ ticks. The tickmodifier 'NoZero' is an abbreviation for
+ 'OmitTick(0)' and the ticklabel 'NoZeroFormat' is an abbrevation
+ for 'OmitFormat(0)'.
+
+ It is also possible to specify custom tick locations with
+ 'LeftTicks', 'RightTicks', and 'Ticks' by passing explicit real
+ arrays 'Ticks' and (optionally) 'ticks' containing the locations of
+ the major and minor ticks, respectively:
+ ticks LeftTicks(Label format="", ticklabel ticklabel=null,
+ bool beginlabel=true, bool endlabel=true,
+ real[] Ticks, real[] ticks=new real[],
+ real Size=0, real size=0, bool extend=false,
+ pen pTick=nullpen, pen ptick=nullpen)
+
+ * void yaxis(picture pic=currentpicture, Label L="", axis axis=XZero,
+ real ymin=-infinity, real ymax=infinity, pen p=currentpen,
+ ticks ticks=NoTicks, arrowbar arrow=None, bool above=false,
+ bool autorotate=true);
+
+ Draw a y axis on picture 'pic' from y='ymin' to y='ymax' using pen
+ 'p', optionally labelling it with a Label 'L' that is autorotated
+ unless 'autorotate=false'. The relative location of the label (a
+ real number from [0,1]) defaults to 1 (*note Label::). An infinite
+ value of 'ymin' or 'ymax' specifies that the corresponding axis
+ limit will be automatically determined from the picture limits.
+ The optional 'arrow' argument takes the same values as in the
+ 'draw' command (*note arrows::). The axis is drawn before any
+ existing objects in 'pic' unless 'above=true'. The tick type is
+ specified by 'ticks' and the axis placement is determined by one of
+ the following 'axis' types:
+
+ 'XZero(bool extend=true)'
+ Request a y axis at x=0 (or x=1 on a logarithmic axis)
+ extending to the full dimensions of the picture, unless
+ 'extend'=false.
+
+ 'XEquals(real X, bool extend=true)'
+ Request a y axis at x='X' extending to the full dimensions of
+ the picture, unless 'extend'=false.
+
+ 'Left(bool extend=false)'
+ Request a left axis.
+
+ 'Right(bool extend=false)'
+ Request a right axis.
+
+ 'LeftRight(bool extend=false)'
+ Request a left and right axis.
+
+ * For convenience, the functions
+ void xequals(picture pic=currentpicture, Label L="", real x,
+ bool extend=false, real ymin=-infinity, real ymax=infinity,
+ pen p=currentpen, ticks ticks=NoTicks, bool above=true,
+ arrowbar arrow=None);
+ and
+ void yequals(picture pic=currentpicture, Label L="", real y,
+ bool extend=false, real xmin=-infinity, real xmax=infinity,
+ pen p=currentpen, ticks ticks=NoTicks, bool above=true,
+ arrowbar arrow=None);
+ can be respectively used to call 'yaxis' and 'xaxis' with the
+ appropriate axis types 'XEquals(x,extend)' and 'YEquals(y,extend)'.
+ This is the recommended way of drawing vertical or horizontal lines
+ and axes at arbitrary locations.
+
+ * void axes(picture pic=currentpicture, Label xlabel="", Label ylabel="",
+ bool extend=true,
+ pair min=(-infinity,-infinity), pair max=(infinity,infinity),
+ pen p=currentpen, arrowbar arrow=None, bool above=false);
+ This convenience routine draws both x and y axes on picture 'pic'
+ from 'min' to 'max', with optional labels 'xlabel' and 'ylabel' and
+ any arrows specified by 'arrow'. The axes are drawn on top of
+ existing objects in 'pic' only if 'above=true'.
+
+ * void axis(picture pic=currentpicture, Label L="", path g,
+ pen p=currentpen, ticks ticks, ticklocate locate,
+ arrowbar arrow=None, int[] divisor=new int[],
+ bool above=false, bool opposite=false);
+
+ This routine can be used to draw on picture 'pic' a general axis
+ based on an arbitrary path 'g', using pen 'p'. One can optionally
+ label the axis with Label 'L' and add an arrow 'arrow'. The tick
+ type is given by 'ticks'. The optional integer array 'divisor'
+ specifies what tick divisors to try in the attempt to produce
+ uncrowded tick labels. A 'true' value for the flag 'opposite'
+ identifies an unlabelled secondary axis (typically drawn opposite a
+ primary axis). The axis is drawn before any existing objects in
+ 'pic' unless 'above=true'. The tick locator 'ticklocate' is
+ constructed by the routine
+ ticklocate ticklocate(real a, real b, autoscaleT S=defaultS,
+ real tickmin=-infinity, real tickmax=infinity,
+ real time(real)=null, pair dir(real)=zero);
+ where 'a' and 'b' specify the respective tick values at
+ 'point(g,0)' and 'point(g,length(g))', 'S' specifies the
+ autoscaling transformation, the function 'real time(real v)'
+ returns the time corresponding to the value 'v', and 'pair dir(real
+ t)' returns the absolute tick direction as a function of 't' (zero
+ means draw the tick perpendicular to the axis).
+
+ * These routines are useful for manually putting ticks and labels on
+ axes (if the variable 'Label' is given as the 'Label' argument, the
+ 'format' argument will be used to format a string based on the tick
+ location):
+ void xtick(picture pic=currentpicture, Label L="", explicit pair z,
+ pair dir=N, string format="",
+ real size=Ticksize, pen p=currentpen);
+ void xtick(picture pic=currentpicture, Label L="", real x,
+ pair dir=N, string format="",
+ real size=Ticksize, pen p=currentpen);
+ void ytick(picture pic=currentpicture, Label L="", explicit pair z,
+ pair dir=E, string format="",
+ real size=Ticksize, pen p=currentpen);
+ void ytick(picture pic=currentpicture, Label L="", real y,
+ pair dir=E, string format="",
+ real size=Ticksize, pen p=currentpen);
+ void tick(picture pic=currentpicture, pair z,
+ pair dir, real size=Ticksize, pen p=currentpen);
+ void labelx(picture pic=currentpicture, Label L="", explicit pair z,
+ align align=S, string format="", pen p=currentpen);
+ void labelx(picture pic=currentpicture, Label L="", real x,
+ align align=S, string format="", pen p=currentpen);
+ void labelx(picture pic=currentpicture, Label L,
+ string format="", explicit pen p=currentpen);
+ void labely(picture pic=currentpicture, Label L="", explicit pair z,
+ align align=W, string format="", pen p=currentpen);
+ void labely(picture pic=currentpicture, Label L="", real y,
+ align align=W, string format="", pen p=currentpen);
+ void labely(picture pic=currentpicture, Label L,
+ string format="", explicit pen p=currentpen);
+
+ Here are some simple examples of two-dimensional graphs:
+
+ 1. This example draws a textbook-style graph of y= exp(x), with the y
+ axis starting at y=0:
+ import graph;
+ size(150,0);
+
+ real f(real x) {return exp(x);}
+ pair F(real x) {return (x,f(x));}
+
+ draw(graph(f,-4,2,operator ..),red);
+
+ xaxis("$x$");
+ yaxis("$y$",0);
+
+ labely(1,E);
+ label("$e^x$",F(1),SE);
+
+
+ [./exp]
+
+ 2. The next example draws a scientific-style graph with a legend. The
+ position of the legend can be adjusted either explicitly or by
+ using the graphical user interface (*note GUI::). If an
+ 'UnFill(real xmargin=0, real ymargin=xmargin)' or 'Fill(pen)'
+ option is specified to 'add', the legend will obscure any
+ underlying objects. Here we illustrate how to clip the portion of
+ the picture covered by a label:
+
+ import graph;
+
+ size(400,200,IgnoreAspect);
+
+ real Sin(real t) {return sin(2pi*t);}
+ real Cos(real t) {return cos(2pi*t);}
+
+ draw(graph(Sin,0,1),red,"$\sin(2\pi x)$");
+ draw(graph(Cos,0,1),blue,"$\cos(2\pi x)$");
+
+ xaxis("$x$",BottomTop,LeftTicks);
+ yaxis("$y$",LeftRight,RightTicks(trailingzero));
+
+ label("LABEL",point(0),UnFill(1mm));
+
+ add(legend(),point(E),20E,UnFill);
+
+ [./lineargraph0]
+
+ To specify a fixed size for the graph proper, use 'attach':
+ import graph;
+
+ size(250,200,IgnoreAspect);
+
+ real Sin(real t) {return sin(2pi*t);}
+ real Cos(real t) {return cos(2pi*t);}
+
+ draw(graph(Sin,0,1),red,"$\sin(2\pi x)$");
+ draw(graph(Cos,0,1),blue,"$\cos(2\pi x)$");
+
+ xaxis("$x$",BottomTop,LeftTicks);
+ yaxis("$y$",LeftRight,RightTicks(trailingzero));
+
+ label("LABEL",point(0),UnFill(1mm));
+
+ attach(legend(),truepoint(E),20E,UnFill);
+
+ A legend can have multiple entries per line:
+ import graph;
+ size(8cm,6cm,IgnoreAspect);
+
+ typedef real realfcn(real);
+ realfcn F(real p) {
+ return new real(real x) {return sin(p*x);};
+ };
+
+ for(int i=1; i < 5; ++i)
+ draw(graph(F(i*pi),0,1),Pen(i),
+ "$\sin("+(i == 1 ? "" : (string) i)+"\pi x)$");
+ xaxis("$x$",BottomTop,LeftTicks);
+ yaxis("$y$",LeftRight,RightTicks(trailingzero));
+
+ attach(legend(2),(point(S).x,truepoint(S).y),10S,UnFill);
+
+ [./legend]
+
+ 3. This example draws a graph of one array versus another (both of the
+ same size) using custom tick locations and a smaller font size for
+ the tick labels on the y axis.
+ import graph;
+
+ size(200,150,IgnoreAspect);
+
+ real[] x={0,1,2,3};
+ real[] y=x^2;
+
+ draw(graph(x,y),red);
+
+ xaxis("$x$",BottomTop,LeftTicks);
+ yaxis("$y$",LeftRight,
+ RightTicks(Label(fontsize(8pt)),new real[]{0,4,9}));
+
+ [./datagraph]
+
+ 4. This example shows how to graph columns of data read from a file.
+ import graph;
+
+ size(200,150,IgnoreAspect);
+
+ file in=input("filegraph.dat").line();
+ real[][] a=in;
+ a=transpose(a);
+
+ real[] x=a[0];
+ real[] y=a[1];
+
+ draw(graph(x,y),red);
+
+ xaxis("$x$",BottomTop,LeftTicks);
+ yaxis("$y$",LeftRight,RightTicks);
+
+ [./filegraph]
+
+ 5. The next example draws two graphs of an array of coordinate pairs,
+ using frame alignment and data markers. In the left-hand graph,
+ the markers, constructed with
+ marker marker(path g, markroutine markroutine=marknodes,
+ pen p=currentpen, filltype filltype=NoFill,
+ bool above=true);
+ using the path 'unitcircle' (*note filltype::), are drawn below
+ each node. Any frame can be converted to a marker, using
+ marker marker(frame f, markroutine markroutine=marknodes,
+ bool above=true);
+ In the right-hand graph, the unit n-sided regular polygon
+ 'polygon(int n)' and the unit n-point cyclic cross 'cross(int n,
+ bool round=true, real r=0)' (where 'r' is an optional "inner"
+ radius) are used to build a custom marker frame. Here
+ 'markuniform(bool centered=false, int n, bool rotated=false)' adds
+ this frame at 'n' uniformly spaced points along the arclength of
+ the path, optionally rotated by the angle of the local tangent to
+ the path (if centered is true, the frames will be centered within
+ 'n' evenly spaced arclength intervals). Alternatively, one can use
+ markroutine 'marknodes' to request that the marks be placed at each
+ Bezier node of the path, or markroutine 'markuniform(pair z(real
+ t), real a, real b, int n)' to place marks at points 'z(t)' for n
+ evenly spaced values of 't' in '[a,b]'.
+
+ These markers are predefined:
+ marker[] Mark={
+ marker(scale(circlescale)*unitcircle),
+ marker(polygon(3)),marker(polygon(4)),
+ marker(polygon(5)),marker(invert*polygon(3)),
+ marker(cross(4)),marker(cross(6))
+ };
+
+ marker[] MarkFill={
+ marker(scale(circlescale)*unitcircle,Fill),marker(polygon(3),Fill),
+ marker(polygon(4),Fill),marker(polygon(5),Fill),
+ marker(invert*polygon(3),Fill)
+ };
+
+ The example also illustrates the 'errorbar' routines:
+
+ void errorbars(picture pic=currentpicture, pair[] z, pair[] dp,
+ pair[] dm={}, bool[] cond={}, pen p=currentpen,
+ real size=0);
+
+ void errorbars(picture pic=currentpicture, real[] x, real[] y,
+ real[] dpx, real[] dpy, real[] dmx={}, real[] dmy={},
+ bool[] cond={}, pen p=currentpen, real size=0);
+
+ Here, the positive and negative extents of the error are given by
+ the absolute values of the elements of the pair array 'dp' and the
+ optional pair array 'dm'. If 'dm' is not specified, the positive
+ and negative extents of the error are assumed to be equal.
+ import graph;
+
+ picture pic;
+ real xsize=200, ysize=140;
+ size(pic,xsize,ysize,IgnoreAspect);
+
+ pair[] f={(5,5),(50,20),(90,90)};
+ pair[] df={(0,0),(5,7),(0,5)};
+
+ errorbars(pic,f,df,red);
+ draw(pic,graph(pic,f),"legend",
+ marker(scale(0.8mm)*unitcircle,red,FillDraw(blue),above=false));
+
+ scale(pic,true);
+
+ xaxis(pic,"$x$",BottomTop,LeftTicks);
+ yaxis(pic,"$y$",LeftRight,RightTicks);
+ add(pic,legend(pic),point(pic,NW),20SE,UnFill);
+
+ picture pic2;
+ size(pic2,xsize,ysize,IgnoreAspect);
+
+ frame mark;
+ filldraw(mark,scale(0.8mm)*polygon(6),green,green);
+ draw(mark,scale(0.8mm)*cross(6),blue);
+
+ draw(pic2,graph(pic2,f),marker(mark,markuniform(5)));
+
+ scale(pic2,true);
+
+ xaxis(pic2,"$x$",BottomTop,LeftTicks);
+ yaxis(pic2,"$y$",LeftRight,RightTicks);
+
+ yequals(pic2,55.0,red+Dotted);
+ xequals(pic2,70.0,red+Dotted);
+
+ // Fit pic to W of origin:
+ add(pic.fit(),(0,0),W);
+
+ // Fit pic2 to E of (5mm,0):
+ add(pic2.fit(),(5mm,0),E);
+
+
+ [./errorbars]
+
+ 6. A custom mark routine can be also be specified:
+ import graph;
+
+ size(200,100,IgnoreAspect);
+
+ markroutine marks() {
+ return new void(picture pic=currentpicture, frame f, path g) {
+ path p=scale(1mm)*unitcircle;
+ for(int i=0; i <= length(g); ++i) {
+ pair z=point(g,i);
+ frame f;
+ if(i % 4 == 0) {
+ fill(f,p);
+ add(pic,f,z);
+ } else {
+ if(z.y > 50) {
+ pic.add(new void(frame F, transform t) {
+ path q=shift(t*z)*p;
+ unfill(F,q);
+ draw(F,q);
+ });
+ } else {
+ draw(f,p);
+ add(pic,f,z);
+ }
+ }
+ }
+ };
+ }
+
+ pair[] f={(5,5),(40,20),(55,51),(90,30)};
+
+ draw(graph(f),marker(marks()));
+
+ scale(true);
+
+ xaxis("$x$",BottomTop,LeftTicks);
+ yaxis("$y$",LeftRight,RightTicks);
+
+ [./graphmarkers]
+
+ 7. This example shows how to label an axis with arbitrary strings.
+ import graph;
+
+ size(400,150,IgnoreAspect);
+
+ real[] x=sequence(12);
+ real[] y=sin(2pi*x/12);
+
+ scale(false);
+
+ string[] month={"Jan","Feb","Mar","Apr","May","Jun",
+ "Jul","Aug","Sep","Oct","Nov","Dec"};
+
+ draw(graph(x,y),red,MarkFill[0]);
+
+ xaxis(BottomTop,LeftTicks(new string(real x) {
+ return month[round(x % 12)];}));
+ yaxis("$y$",LeftRight,RightTicks(4));
+
+ [./monthaxis]
+
+ 8. The next example draws a graph of a parametrized curve. The calls
+ to
+ xlimits(picture pic=currentpicture, real min=-infinity,
+ real max=infinity, bool crop=NoCrop);
+ and the analogous function 'ylimits' can be uncommented to set the
+ respective axes limits for picture 'pic' to the specified 'min' and
+ 'max' values. Alternatively, the function
+ void limits(picture pic=currentpicture, pair min, pair max, bool crop=NoCrop);
+ can be used to limit the axes to the box having opposite vertices
+ at the given pairs). Existing objects in picture 'pic' will be
+ cropped to lie within the given limits if 'crop'='Crop'. The
+ function 'crop(picture pic)' can be used to crop a graph to the
+ current graph limits.
+ import graph;
+
+ size(0,200);
+
+ real x(real t) {return cos(2pi*t);}
+ real y(real t) {return sin(2pi*t);}
+
+ draw(graph(x,y,0,1));
+
+ //limits((0,-1),(1,0),Crop);
+
+ xaxis("$x$",BottomTop,LeftTicks);
+ yaxis("$y$",LeftRight,RightTicks(trailingzero));
+
+
+
+ [./parametricgraph]
+
+ The next example illustrates how one can extract a common axis
+ scaling factor.
+ import graph;
+
+ axiscoverage=0.9;
+ size(200,IgnoreAspect);
+
+ real[] x={-1e-11,1e-11};
+ real[] y={0,1e6};
+
+ real xscale=round(log10(max(x)));
+ real yscale=round(log10(max(y)))-1;
+
+ draw(graph(x*10^(-xscale),y*10^(-yscale)),red);
+
+ xaxis("$x/10^{"+(string) xscale+"}$",BottomTop,LeftTicks);
+ yaxis("$y/10^{"+(string) yscale+"}$",LeftRight,RightTicks(trailingzero));
+
+ [./scaledgraph]
+
+ Axis scaling can be requested and/or automatic selection of the
+ axis limits can be inhibited with one of these 'scale' routines:
+ void scale(picture pic=currentpicture, scaleT x, scaleT y);
+
+ void scale(picture pic=currentpicture, bool xautoscale=true,
+ bool yautoscale=xautoscale, bool zautoscale=yautoscale);
+
+ This sets the scalings for picture 'pic'. The 'graph' routines
+ accept an optional 'picture' argument for determining the
+ appropriate scalings to use; if none is given, it uses those set
+ for 'currentpicture'.
+
+ Two frequently used scaling routines 'Linear' and 'Log' are
+ predefined in 'graph'.
+
+ All picture coordinates (including those in paths and those given
+ to the 'label' and 'limits' functions) are always treated as linear
+ (post-scaled) coordinates. Use
+ pair Scale(picture pic=currentpicture, pair z);
+ to convert a graph coordinate into a scaled picture coordinate.
+
+ The x and y components can be individually scaled using the
+ analogous routines
+ real ScaleX(picture pic=currentpicture, real x);
+ real ScaleY(picture pic=currentpicture, real y);
+
+ The predefined scaling routines can be given two optional boolean
+ arguments: 'automin=false' and 'automax=automin'. These default to
+ 'false' but can be respectively set to 'true' to enable automatic
+ selection of "nice" axis minimum and maximum values. The 'Linear'
+ scaling can also take as optional final arguments a multiplicative
+ scaling factor and intercept (e.g. for a depth axis, 'Linear(-1)'
+ requests axis reversal).
+
+ For example, to draw a log/log graph of a function, use
+ 'scale(Log,Log)':
+ import graph;
+
+ size(200,200,IgnoreAspect);
+
+ real f(real t) {return 1/t;}
+
+ scale(Log,Log);
+
+ draw(graph(f,0.1,10));
+
+ //limits((1,0.1),(10,0.5),Crop);
+
+ dot(Label("(3,5)",align=S),Scale((3,5)));
+
+ xaxis("$x$",BottomTop,LeftTicks);
+ yaxis("$y$",LeftRight,RightTicks);
+
+
+ [./loggraph]
+
+ By extending the ticks, one can easily produce a logarithmic grid:
+ import graph;
+ size(200,200,IgnoreAspect);
+
+ real f(real t) {return 1/t;}
+
+ scale(Log,Log);
+ draw(graph(f,0.1,10),red);
+ pen thin=linewidth(0.5*linewidth());
+ xaxis("$x$",BottomTop,LeftTicks(begin=false,end=false,extend=true,
+ ptick=thin));
+ yaxis("$y$",LeftRight,RightTicks(begin=false,end=false,extend=true,
+ ptick=thin));
+
+
+
+ [./loggrid]
+
+ One can also specify custom tick locations and formats for
+ logarithmic axes:
+ import graph;
+
+ size(300,175,IgnoreAspect);
+ scale(Log,Log);
+ draw(graph(identity,5,20));
+ xlimits(5,20);
+ ylimits(1,100);

+ It is easy to draw logarithmic graphs with respect to other bases:
+ import graph;
+ size(200,IgnoreAspect);
+
+ // Base-2 logarithmic scale on y-axis:
+
+ real log2(real x) {static real log2=log(2); return log(x)/log2;}
+ real pow2(real x) {return 2^x;}
+
+ scaleT yscale=scaleT(log2,pow2,logarithmic=true);
+ scale(Linear,yscale);
+
+ real f(real x) {return 1+x^2;}
+
+ draw(graph(f,-4,4));

+ yaxis("$y$",ymin=1,ymax=f(5),RightTicks(Label(Fill(white))),EndArrow);
+ xaxis("$x$",xmin=-5,xmax=5,LeftTicks,EndArrow);
+
+ [./log2graph]
+
+ Here is an example of "broken" linear x and logarithmic y axes that
+ omit the segments [3,8] and [100,1000], respectively. In the case
+ of a logarithmic axis, the break endpoints are automatically
+ rounded to the nearest integral power of the base.
+ import graph;

+ picture secondaryX(picture primary=currentpicture, void f(picture));
+ picture secondaryY(picture primary=currentpicture, void f(picture));
+
+ In this example, 'secondaryY' is used to draw a secondary linear y
+ axis against a primary logarithmic y axis:
+ import graph;

+
+ size(10cm,5cm,IgnoreAspect);
+

+
+8.27 'palette'
+==============
+
+'Asymptote' can also generate color density images and palettes. The
+following palettes are predefined in 'palette.asy':
+
+'pen[] Grayscale(int NColors=256)'
+ a grayscale palette;
+
+'pen[] Rainbow(int NColors=32766)'
+ a rainbow spectrum;
+
+'pen[] BWRainbow(int NColors=32761)'
+ a rainbow spectrum tapering off to black/white at the ends;
+
+'pen[] BWRainbow2(int NColors=32761)'
+ a double rainbow palette tapering off to black/white at the ends,
+ with a linearly scaled intensity.
+
+'pen[] Wheel(int NColors=32766)'
+ a full color wheel palette;
+
+'pen[] Gradient(int NColors=256 ... pen[] p)'
+ a palette varying linearly over the specified array of pens, using
+ NColors in each interpolation interval;
+
+ The function 'cmyk(pen[] Palette)' may be used to convert any of
+these palettes to the CMYK colorspace.
+
+ A color density plot using palette 'palette' can be generated from a
+function 'f'(x,y) and added to a picture 'pic':
+bounds image(picture pic=currentpicture, real f(real, real),
+ range range=Full, pair initial, pair final,
+ int nx=ngraph, int ny=nx, pen[] palette, bool antialias=false)
+ The function 'f' will be sampled at 'nx' and 'ny' evenly spaced
+points over a rectangle defined by the points 'initial' and 'final',
+respecting the current graphical scaling of 'pic'. The color space is
+scaled according to the z axis scaling (*note automatic scaling::). A
+bounds structure for the function values is returned:
+struct bounds {
+ real min;
+ real max;
+ // Possible tick intervals:
+ int[] divisor;
+}
+This information can be used for generating an optional palette bar.
+The palette color space corresponds to a range of values specified by
+the argument 'range', which can be 'Full', 'Automatic', or an explicit
+range 'Range(real min, real max)'. Here 'Full' specifies a range
+varying from the minimum to maximum values of the function over the
+sampling interval, while 'Automatic' selects "nice" limits. The example
+'imagecontour.asy' illustrates how level sets (contour lines) can be
+drawn on a color density plot (*note contour::).
+
+ A color density plot can also be generated from an explicit real[][]
+array 'data':
+bounds image(picture pic=currentpicture, real[][] f, range range=Full,
+ pair initial, pair final, pen[] palette,
+ bool transpose=(initial.x < final.x && initial.y < final.y),
+ bool copy=true, bool antialias=false);
+If the initial point is to the left and below the final point, by
+default the array indices are interpreted according to the Cartesian
+convention (first index: x, second index: y) rather than the usual
+matrix convention (first index: -y, second index: x).
+
+ To construct an image from an array of irregularly spaced points and
+an array of values 'f' at these points, use one of the routines
+bounds image(picture pic=currentpicture, pair[] z, real[] f,
+ range range=Full, pen[] palette)
+bounds image(picture pic=currentpicture, real[] x, real[] y, real[] f,
+ range range=Full, pen[] palette)
+
+ An optionally labelled palette bar may be generated with the routine
+void palette(picture pic=currentpicture, Label L="", bounds bounds,
+ pair initial, pair final, axis axis=Right, pen[] palette,
+ pen p=currentpen, paletteticks ticks=PaletteTicks,
+ bool copy=true, bool antialias=false);
+ The color space of 'palette' is taken to be over bounds 'bounds' with
+scaling given by the z scaling of 'pic'. The palette orientation is
+specified by 'axis', which may be one of 'Right', 'Left', 'Top', or
+'Bottom'. The bar is drawn over the rectangle from 'initial' to
+'final'. The argument 'paletteticks' is a special tick type (*note
+ticks::) that takes the following arguments:
+paletteticks PaletteTicks(Label format="", ticklabel ticklabel=null,
+ bool beginlabel=true, bool endlabel=true,
+ int N=0, int n=0, real Step=0, real step=0,
+ pen pTick=nullpen, pen ptick=nullpen);
+
+ The image and palette bar can be fit to a frame and added and
+optionally aligned to a picture at the desired location:
+
+size(12cm,12cm);
+
+import graph;
+import palette;
+
+int n=256;

+ PaletteTicks("$%+#.1f$"));
+add(bar.fit(),point(E),30E);
+
+ [./image]
+
+ Here is an example that uses logarithmic scaling of the function
+values:
+
+import graph;
+import palette;
+
+size(10cm,10cm,IgnoreAspect);
+
+real f(real x, real y) {
+ return 0.9*pow10(2*sin(x/5+2*y^0.25)) + 0.1*(1+cos(10*log(y)));

+
+8.28 'three'
+============
+
+This module fully extends the notion of guides and paths in 'Asymptote'
+to three dimensions. It introduces the new types guide3, path3, and
+surface. Guides in three dimensions are specified with the same syntax
+as in two dimensions except that triples '(x,y,z)' are used in place of
+pairs '(x,y)' for the nodes and direction specifiers. This
+generalization of John Hobby's spline algorithm is shape-invariant under
+three-dimensional rotation, scaling, and shifting, and reduces in the
+planar case to the two-dimensional algorithm used in 'Asymptote',
+'MetaPost', and 'MetaFont' [cf. J. C. Bowman, Proceedings in Applied
+Mathematics and Mechanics, 7:1, 2010021-2010022 (2007)].
+
+ For example, a unit circle in the XY plane may be filled and drawn
+like this:
+import three;
+
+size(100);
+
+path3 g=(1,0,0)..(0,1,0)..(-1,0,0)..(0,-1,0)..cycle;
+draw(g);
+draw(O--Z,red+dashed,Arrow3);
+draw(((-1,-1,0)--(1,-1,0)--(1,1,0)--(-1,1,0)--cycle));
+dot(g,red);
+
+ [./unitcircle3]
+and then distorted into a saddle:
+import three;
+
+size(100,0);
+path3 g=(1,0,0)..(0,1,1)..(-1,0,0)..(0,-1,1)..cycle;
+draw(g);
+draw(((-1,-1,0)--(1,-1,0)--(1,1,0)--(-1,1,0)--cycle));
+dot(g,red);
+
+ [./saddle]
+
+ Module 'three' provides constructors for converting two-dimensional
+paths to three-dimensional ones, and vice-versa:
+path3 path3(path p, triple plane(pair)=XYplane);
+path path(path3 p, pair P(triple)=xypart);
+
+ A Bezier surface, the natural two-dimensional generalization of
+Bezier curves, is defined in 'three_surface.asy' as a structure
+containing an array of Bezier patches. Surfaces may drawn with one of
+the routines
+void draw(picture pic=currentpicture, surface s, int nu=1, int nv=1,
+ material surfacepen=currentpen, pen meshpen=nullpen,
+ light light=currentlight, light meshlight=nolight, string name="",
+ render render=defaultrender);
+void draw(picture pic=currentpicture, surface s, int nu=1, int nv=1,
+ material[] surfacepen, pen meshpen,
+ light light=currentlight, light meshlight=nolight, string name="",
+ render render=defaultrender);
+void draw(picture pic=currentpicture, surface s, int nu=1, int nv=1,
+ material[] surfacepen, pen[] meshpen=nullpens,
+ light light=currentlight, light meshlight=nolight, string name="",
+ render render=defaultrender);
+
+ The parameters 'nu' and 'nv' specify the number of subdivisions for
+drawing optional mesh lines for each Bezier patch. The optional 'name'
+parameter is used as a prefix for naming the surface patches in the PRC
+model tree. Here material is a structure defined in 'three_light.asy':
+struct material {
+ pen[] p; // diffusepen,emissivepen,specularpen
+ real opacity;
+ real shininess;
+ real metallic;
+ real fresnel0;
+}
+These material properties are used to implement physically based
+rendering (PBR) using light properties defined in 'plain_prethree.asy'
+and 'three_light.asy':
+struct light {
+ real[][] diffuse;
+ real[][] specular;
+ pen background=nullpen; // Background color of the canvas.
+ real specularfactor;
+ triple[] position; // Only directional lights are currently implemented.
+}
+
+light Viewport=light(specularfactor=3,(0.25,-0.25,1));
+
+light White=light(new pen[] {rgb(0.38,0.38,0.45),rgb(0.6,0.6,0.67),
+ rgb(0.5,0.5,0.57)},specularfactor=3,
+ new triple[] {(-2,-1.5,-0.5),(2,1.1,-2.5),(-0.5,0,2)});
+
+light Headlamp=light(gray(0.8),specular=gray(0.7),
+ specularfactor=3,dir(42,48));
+
+currentlight=Headlamp;
+
+light nolight;
+ The 'currentlight.background' (or 'background' member of the
+specified 'light') can be used to set the background colour for 2D (or
+3D) images. The default background is white for 'HTML' images and
+transparent for all other formats. One can request a completely
+transparent background for 3D 'WebGL' images with
+'currentlight.background=black+opacity(0.0);'
+
+ Sample Bezier surfaces are contained in the example files
+'BezierSurface.asy', 'teapot.asy', and 'parametricsurface.asy'. The
+structure 'render' contains specialized rendering options documented at
+the beginning of module 'three'.
+
+ The examples 'elevation.asy' and 'sphericalharmonic.asy' illustrate
+how to draw a surface with patch-dependent colors. The examples
+'vertexshading.asy' and 'smoothelevation.asy' illustrate
+vertex-dependent colors, which are supported by 'Asymptote''s native
+'OpenGL'/'WebGL' renderers and the two-dimensional vector output format
+('settings.render=0'). Since the PRC output format does not currently
+support vertex shading of Bezier surfaces, PRC patches are shaded with
+the mean of the four vertex colors.
+
+ A surface can be constructed from a cyclic 'path3' with the
+constructor
+surface surface(path3 external, triple[] internal=new triple[],
+ pen[] colors=new pen[], bool3 planar=default);
+and then filled:
+draw(surface(unitsquare3,new triple[] {X,Y,Z,O}),red);
+draw(surface(O--X{Y}..Y{-X}--cycle,new triple[] {Z}),red);
+draw(surface(path3(polygon(5))),red,nolight);
+draw(surface(unitcircle3),red,nolight);
+draw(surface(unitcircle3,new pen[] {red,green,blue,black}),nolight);
+The first example draws a Bezier patch and the second example draws a
+Bezier triangle. The third and fourth examples are planar surfaces.
+The last example constructs a patch with vertex-specific colors. A
+three-dimensional planar surface in the plane 'plane' can be constructed
+from a two-dimensional cyclic path 'g' with the constructor
+surface surface(path p, triple plane(pair)=XYplane);
+and then filled:
+draw(surface((0,0)--E+2N--2E--E+N..0.2E..cycle),red);
+Planar Bezier surfaces patches are constructed using Orest Shardt's
+'bezulate' routine, which decomposes (possibly nonsimply connected)
+regions bounded (according to the 'zerowinding' fill rule) by simple
+cyclic paths (intersecting only at the endpoints) into subregions
+bounded by cyclic paths of length '4' or less.
+
+ A more efficient routine also exists for drawing tessellations
+composed of many 3D triangles, with specified vertices, and optional
+normals or vertex colors:
+void draw(picture pic=currentpicture, triple[] v, int[][] vi,
+ triple[] n={}, int[][] ni=vi, material m=currentpen, pen[] p={},
+ int[][] pi=vi, light light=currentlight);
+ Here, the triple array 'v' lists the (typically distinct) vertices,
+while the array 'vi' contains integer arrays of length 3 containing the
+indices of the elements in 'v' that form the vertices of each triangle.
+Similarly, the arguments 'n' and 'ni' contain optional normal data and
+'p' and 'pi' contain optional pen vertex data. If more than one normal
+or pen is specified for a vertex, the last one specified is used. An
+example of this tessellation facility is given in 'triangles.asy'.
+
+ Arbitrary thick three-dimensional curves and line caps (which the
+'OpenGL' standard does not require implementations to provide) are
+constructed with
+tube tube(path3 p, real width, render render=defaultrender);
+this returns a tube structure representing a tube of diameter 'width'
+centered approximately on 'g'. The tube structure consists of a surface
+'s' and the actual tube center, path3 'center'. Drawing thick lines as
+tubes can be slow to render, especially with the 'Adobe Reader'
+renderer. The setting 'thick=false' can be used to disable this feature
+and force all lines to be drawn with 'linewidth(0)' (one pixel wide,
+regardless of the resolution). By default, mesh and contour lines in
+three-dimensions are always drawn thin, unless an explicit line width is
+given in the pen parameter or the setting 'thin' is set to 'false'. The
+pens 'thin()' and 'thick()' defined in 'plain_pens.asy' can also be used
+to override these defaults for specific draw commands.
+
+There are five choices for viewing 3D 'Asymptote' output:
+
+ 1. Use the native 'Asymptote' adaptive 'OpenGL'-based renderer (with
+ the command-line option '-V' and the default settings
+ 'outformat=""' and 'render=-1'). On 'UNIX' systems with graphics
+ support for multisampling, the sample width can be controlled with
+ the setting 'multisample'. The ratio of physical to logical screen
+ pixels can be specified with the setting 'devicepixelratio'. An
+ initial screen position can be specified with the pair setting
+ 'position', where negative values are interpreted as relative to
+ the corresponding maximum screen dimension. The default settings
+ import settings;
+ leftbutton=new string[] {"rotate","zoom","shift","pan"};
+ middlebutton=new string[] {""};
+ rightbutton=new string[] {"zoom","rotateX","rotateY","rotateZ"};
+ wheelup=new string[] {"zoomin"};
+ wheeldown=new string[] {"zoomout"};
+ bind the mouse buttons as follows:
+ * Left: rotate
+ * Shift Left: zoom
+ * Ctrl Left: shift viewport
+ * Alt Left: pan
+ * Wheel Up: zoom in
+ * Wheel Down: zoom out
+ * Right: zoom
+ * Shift Right: rotate about the X axis
+ * Ctrl Right: rotate about the Y axis
+ * Alt Right: rotate about the Z axis
+
+ The keyboard shortcuts are:
+ * h: home
+ * f: toggle fitscreen
+ * x: spin about the X axis
+ * y: spin about the Y axis
+ * z: spin about the Z axis
+ * s: stop spinning
+ * m: rendering mode (solid/patch/mesh)
+ * e: export
+ * c: show camera parameters
+ * p: play animation
+ * r: reverse animation
+ * : step animation
+ * +: expand
+ * =: expand
+ * >: expand
+ * -: shrink
+ * _: shrink
+ * <: shrink
+ * q: exit
+ * Ctrl-q: exit
+
+ 2. Generate 'WebGL' interactive vector graphics output with the the
+ command-line option and '-f html' (or the setting
+ 'outformat="html"'). The resulting 3D HTML file can then be viewed
+ directly in any modern desktop or mobile browser, or even embedded
+ within another web page:
+ <div>
+ <object data="logo3.html"
+ style="width:210;height:140;position:relative;top:0;left:0;">
+ </object>
+ </div>
+
+ Normally, 'WebGL' files generated by 'Asymptote' are dynamically
+ remeshed to fit the browser window dimensions. However, the
+ setting 'absolute=true' can be used to force the image to be
+ rendered at its designed size (accounting for multiple device
+ pixels per 'css' pixel).
+
+ The interactive 'WebGL' files produced by 'Asymptote' use the
+ default mouse and (many of the same) key bindings as the 'OpenGL'
+ renderer. Zooming via the mouse wheel of a 'WebGL' image embedded
+ within another page is disabled until the image is activated by a
+ click or touch event and will remain enabled until the 'ESC' key is
+ pressed.
+
+ By default, viewing the 3D HTML files generated by Asymptote
+ requires network access to download the 'AsyGL' rendering library,
+ which is normally cached by the browser for future use. However,
+ the setting 'offline=true' can be used to embed this small (about
+ 48kB) library within a stand-alone HTML file that can be viewed
+ offline.
+
+ 3. Render the scene to a specified rasterized format 'outformat' at
+ the resolution of 'n' pixels per 'bp', as specified by the setting
+ 'render=n'. A negative value of 'n' is interpreted as '|2n|' for
+ EPS and PDF formats and '|n|' for other formats. The default value
+ of 'render' is -1. By default, the scene is internally rendered at
+ twice the specified resolution; this can be disabled by setting
+ 'antialias=1'. High resolution rendering is done by tiling the
+ image. If your graphics card allows it, the rendering can be made
+ more efficient by increasing the maximum tile size 'maxtile' to
+ your screen dimensions (indicated by 'maxtile=(0,0)'. If your
+ video card generates unwanted black stripes in the output, try
+ setting the horizontal and vertical components of 'maxtiles' to
+ something less than your screen dimensions. The tile size is also
+ limited by the setting 'maxviewport', which restricts the maximum
+ width and height of the viewport. On 'UNIX' systems some graphics
+ drivers support batch mode ('-noV') rendering in an iconified
+ window; this can be enabled with the setting 'iconify=true'.
+
+ 4. Embed the 3D PRC format in a PDF file and view the resulting PDF
+ file with version '9.0' or later of 'Adobe Reader'. In addition to
+ the default 'settings.prc=true', this requires
+ 'settings.outformat="pdf"', which can be specified by the command
+ line option '-f pdf', put in the 'Asymptote' configuration file
+ (*note configuration file::), or specified in the script before
+ module 'three' (or 'graph3') is imported. The 'media9' LaTeX
+ package is also required (*note embed::). The example '100d.asy'
+ illustrates how one can generate a list of predefined views (see
+ '100d.views'). A stationary preview image with a resolution of 'n'
+ pixels per 'bp' can be embedded with the setting 'render=n'; this
+ allows the file to be viewed with other 'PDF' viewers.
+ Alternatively, the file 'externalprc.tex' illustrates how the
+ resulting PRC and rendered image files can be extracted and
+ processed in a separate 'LaTeX' file. However, see *note LaTeX
+ usage:: for an easier way to embed three-dimensional 'Asymptote'
+ pictures within 'LaTeX'. For specialized applications where only
+ the raw PRC file is required, specify 'settings.outformat="prc"'.
+ The PRC specification is available from
+ <https://web.archive.org/web/20081204104459/http://livedocs.adobe.com/acrobat_sdk/9/Acrobat9_HTMLHelp/API_References/PRCReference/PRC_Format_Specification/>
+
+ 5. Project the scene to a two-dimensional vector (EPS or PDF) format
+ with 'render=0'. Only limited hidden surface removal facilities
+ are currently available with this approach (*note PostScript3D::).
+
+ Automatic picture sizing in three dimensions is accomplished with
+double deferred drawing. The maximal desired dimensions of the scene in
+each of the three dimensions can optionally be specified with the
+routine
+void size3(picture pic=currentpicture, real x, real y=x, real z=y,
+ bool keepAspect=pic.keepAspect);
+A simplex linear programming problem is then solved to produce a 3D
+version of a frame (actually implemented as a 3D picture). The result
+is then fit with another application of deferred drawing to the viewport
+dimensions corresponding to the usual two-dimensional picture 'size'
+parameters. The global pair 'viewportmargin' may be used to add
+horizontal and vertical margins to the viewport dimensions.
+Alternatively, a minimum 'viewportsize' may be specified. A 3D picture
+'pic' can be explicitly fit to a 3D frame by calling
+frame pic.fit3(projection P=currentprojection);
+and then added to picture 'dest' about 'position' with
+void add(picture dest=currentpicture, frame src, triple position=(0,0,0));
+
+ For convenience, the 'three' module defines 'O=(0,0,0)', 'X=(1,0,0)',
+'Y=(0,1,0)', and 'Z=(0,0,1)', along with a unitcircle in the XY plane:
+path3 unitcircle3=X..Y..-X..-Y..cycle;
+
+ A general (approximate) circle can be drawn perpendicular to the
+direction 'normal' with the routine
+path3 circle(triple c, real r, triple normal=Z);
+
+ A circular arc centered at 'c' with radius 'r' from
+'c+r*dir(theta1,phi1)' to 'c+r*dir(theta2,phi2)', drawing
+counterclockwise relative to the normal vector
+'cross(dir(theta1,phi1),dir(theta2,phi2))' if 'theta2 > theta1' or if
+'theta2 == theta1' and 'phi2 >= phi1', can be constructed with
+path3 arc(triple c, real r, real theta1, real phi1, real theta2, real phi2,
+ triple normal=O);
+ The normal must be explicitly specified if 'c' and the endpoints are
+colinear. If 'r' < 0, the complementary arc of radius '|r|' is
+constructed. For convenience, an arc centered at 'c' from triple 'v1'
+to 'v2' (assuming '|v2-c|=|v1-c|') in the direction CCW
+(counter-clockwise) or CW (clockwise) may also be constructed with
+path3 arc(triple c, triple v1, triple v2, triple normal=O,
+ bool direction=CCW);
+When high accuracy is needed, the routines 'Circle' and 'Arc' defined in
+'graph3' may be used instead. See *note GaussianSurface:: for an
+example of a three-dimensional circular arc.
+
+ The representation 'O--O+u--O+u+v--O+v--cycle' of the plane passing
+through point 'O' with normal 'cross(u,v)' is returned by
+path3 plane(triple u, triple v, triple O=O);
+ A three-dimensional box with opposite vertices at triples 'v1' and
+'v2' may be drawn with the function
+path3[] box(triple v1, triple v2);
+For example, a unit box is predefined as
+path3[] unitbox=box(O,(1,1,1));
+ 'Asymptote' also provides optimized definitions for the
+three-dimensional paths 'unitsquare3' and 'unitcircle3', along with the
+surfaces 'unitdisk', 'unitplane', 'unitcube', 'unitcylinder',
+'unitcone', 'unitsolidcone', 'unitfrustum(real t1, real t2)',
+'unitsphere', and 'unithemisphere'.
+
+These projections to two dimensions are predefined:
+'oblique'
+'oblique(real angle)'
+ The point '(x,y,z)' is projected to '(x-0.5z,y-0.5z)'. If an
+ optional real argument is given, the negative z axis is drawn at
+ this angle in degrees. The projection 'obliqueZ' is a synonym for
+ 'oblique'.
+
+'obliqueX'
+'obliqueX(real angle)'
+ The point '(x,y,z)' is projected to '(y-0.5x,z-0.5x)'. If an
+ optional real argument is given, the negative x axis is drawn at
+ this angle in degrees.
+
+'obliqueY'
+'obliqueY(real angle)'
+ The point '(x,y,z)' is projected to '(x+0.5y,z+0.5y)'. If an
+ optional real argument is given, the positive y axis is drawn at
+ this angle in degrees.
+
+'orthographic(triple camera, triple up=Z, triple target=O,
+ real zoom=1, pair viewportshift=0, bool showtarget=true,
+ bool center=false)'
+ This projects from three to two dimensions using the view as seen
+ at a point infinitely far away in the direction 'unit(camera)',
+ orienting the camera so that, if possible, the vector 'up' points
+ upwards. Parallel lines are projected to parallel lines. The
+ bounding volume is expanded to include 'target' if
+ 'showtarget=true'. If 'center=true', the target will be adjusted
+ to the center of the bounding volume.
+
+'orthographic(real x, real y, real z, triple up=Z, triple target=O,
+ real zoom=1, pair viewportshift=0, bool showtarget=true,
+ bool center=false)'
+ This is equivalent to
+ orthographic((x,y,z),up,target,zoom,viewportshift,showtarget,center)
+
+ The routine
+ triple camera(real alpha, real beta);
+ can be used to compute the camera position with the x axis below
+ the horizontal at angle 'alpha', the y axis below the horizontal at
+ angle 'beta', and the z axis up.
+
+'perspective(triple camera, triple up=Z, triple target=O,
+ real zoom=1, real angle=0, pair viewportshift=0,
+ bool showtarget=true, bool autoadjust=true,
+ bool center=autoadjust)'
+ This projects from three to two dimensions, taking account of
+ perspective, as seen from the location 'camera' looking at
+ 'target', orienting the camera so that, if possible, the vector
+ 'up' points upwards. If 'render=0', projection of
+ three-dimensional cubic Bezier splines is implemented by
+ approximating a two-dimensional nonuniform rational B-spline
+ (NURBS) with a two-dimensional Bezier curve containing additional
+ nodes and control points. If 'autoadjust=true', the camera will
+ automatically be adjusted to lie outside the bounding volume for
+ all possible interactive rotations about 'target'. If
+ 'center=true', the target will be adjusted to the center of the
+ bounding volume.
+
+'perspective(real x, real y, real z, triple up=Z, triple target=O,
+ real zoom=1, real angle=0, pair viewportshift=0,
+ bool showtarget=true, bool autoadjust=true,
+ bool center=autoadjust)'
+ This is equivalent to
+ perspective((x,y,z),up,target,zoom,angle,viewportshift,showtarget,
+ autoadjust,center)
+
+The default projection, 'currentprojection', is initially set to
+'perspective(5,4,2)'.
+
+ We also define standard orthographic views used in technical drawing:
+projection LeftView=orthographic(-X,showtarget=true);
+projection RightView=orthographic(X,showtarget=true);
+projection FrontView=orthographic(-Y,showtarget=true);
+projection BackView=orthographic(Y,showtarget=true);
+projection BottomView=orthographic(-Z,showtarget=true);
+projection TopView=orthographic(Z,showtarget=true);
+The function
+void addViews(picture dest=currentpicture, picture src,
+ projection[][] views=SixViewsUS,
+ bool group=true, filltype filltype=NoFill);
+adds to picture 'dest' an array of views of picture 'src' using the
+layout projection[][] 'views'. The default layout 'SixViewsUS' aligns
+the projection 'FrontView' below 'TopView' and above 'BottomView', to
+the right of 'LeftView' and left of 'RightView' and 'BackView'. The
+predefined layouts are:
+projection[][] ThreeViewsUS={{TopView},
+ {FrontView,RightView}};
+
+projection[][] SixViewsUS={{null,TopView},
+ {LeftView,FrontView,RightView,BackView},
+ {null,BottomView}};
+
+projection[][] ThreeViewsFR={{RightView,FrontView},
+ {null,TopView}};
+
+projection[][] SixViewsFR={{null,BottomView},
+ {RightView,FrontView,LeftView,BackView},
+ {null,TopView}};
+
+projection[][] ThreeViews={{FrontView,TopView,RightView}};
+
+projection[][] SixViews={{FrontView,TopView,RightView},
+ {BackView,BottomView,LeftView}};
+
+
+ A triple or path3 can be projected to a pair or path, with
+'project(triple, projection P=currentprojection)' or 'project(path3,
+projection P=currentprojection)'.
+
+ It is occasionally useful to be able to invert a projection, sending
+a pair 'z' onto the plane perpendicular to 'normal' and passing through
+'point':
+triple invert(pair z, triple normal, triple point,
+ projection P=currentprojection);
+A pair 'z' on the projection plane can be inverted to a triple with the
+routine
+triple invert(pair z, projection P=currentprojection);
+A pair direction 'dir' on the projection plane can be inverted to a
+triple direction relative to a point 'v' with the routine
+triple invert(pair dir, triple v, projection P=currentprojection).
+
+ Three-dimensional objects may be transformed with one of the
+following built-in transform3 types (the identity transformation is
+'identity4'):
+
+'shift(triple v)'
+ translates by the triple 'v';
+'xscale3(real x)'
+ scales by 'x' in the x direction;
+'yscale3(real y)'
+ scales by 'y' in the y direction;
+'zscale3(real z)'
+ scales by 'z' in the z direction;
+'scale3(real s)'
+ scales by 's' in the x, y, and z directions;
+'scale(real x, real y, real z)'
+ scales by 'x' in the x direction, by 'y' in the y direction, and by
+ 'z' in the z direction;
+'rotate(real angle, triple v)'
+ rotates by 'angle' in degrees about an axis 'v' through the origin;
+'rotate(real angle, triple u, triple v)'
+ rotates by 'angle' in degrees about the axis 'u--v';
+'reflect(triple u, triple v, triple w)'
+ reflects about the plane through 'u', 'v', and 'w'.
+
+ When not multiplied on the left by a transform3, three-dimensional
+TeX Labels are drawn as Bezier surfaces directly on the projection
+plane:
+void label(picture pic=currentpicture, Label L, triple position,
+ align align=NoAlign, pen p=currentpen,
+ light light=nolight, string name="",
+ render render=defaultrender, interaction interaction=
+ settings.autobillboard ? Billboard : Embedded)
+The optional 'name' parameter is used as a prefix for naming the label
+patches in the PRC model tree. The default interaction is 'Billboard',
+which means that labels are rotated interactively so that they always
+face the camera. The interaction 'Embedded' means that the label
+interacts as a normal '3D' surface, as illustrated in the example
+'billboard.asy'. Alternatively, a label can be transformed from the
+'XY' plane by an explicit transform3 or mapped to a specified
+two-dimensional plane with the predefined transform3 types 'XY', 'YZ',
+'ZX', 'YX', 'ZY', 'ZX'. There are also modified versions of these
+transforms that take an optional argument 'projection
+P=currentprojection' that rotate and/or flip the label so that it is
+more readable from the initial viewpoint.
+
+ A transform3 that projects in the direction 'dir' onto the plane with
+normal 'n' through point 'O' is returned by
+transform3 planeproject(triple n, triple O=O, triple dir=n);
+One can use
+triple normal(path3 p);
+to find the unit normal vector to a planar three-dimensional path 'p'.
+As illustrated in the example 'planeproject.asy', a transform3 that
+projects in the direction 'dir' onto the plane defined by a planar path
+'p' is returned by
+transform3 planeproject(path3 p, triple dir=normal(p));
+
+ The functions
+surface extrude(path p, triple axis=Z);
+surface extrude(Label L, triple axis=Z);
+return the surface obtained by extruding path 'p' or Label 'L' along
+'axis'.
+
+ Three-dimensional versions of the path functions 'length', 'size',
+'point', 'dir', 'accel', 'radius', 'precontrol', 'postcontrol',
+'arclength', 'arctime', 'reverse', 'subpath', 'intersect',
+'intersections', 'intersectionpoint', 'intersectionpoints', 'min',
+'max', 'cyclic', and 'straight' are also defined.
+
+ The routine
+real[] intersect(path3 p, surface s, real fuzz=-1);
+returns a real array of length 3 containing the intersection times, if
+any, of a path 'p' with a surface 's'. The routine
+real[][] intersections(path3 p, surface s, real fuzz=-1);
+returns all (unless there are infinitely many) intersection times of a
+path 'p' with a surface 's' as a sorted array of real arrays of length
+3, and
+triple[] intersectionpoints(path3 p, surface s, real fuzz=-1);
+returns the corresponding intersection points. Here, the computations
+are performed to the absolute error specified by 'fuzz', or if 'fuzz <
+0', to machine precision. The routine
+real orient(triple a, triple b, triple c, triple d);
+is a numerically robust computation of 'dot(cross(a-d,b-d),c-d)', which
+is the determinant
+|a.x a.y a.z 1|
+|b.x b.y b.z 1|
+|c.x c.y c.z 1|
+|d.x d.y d.z 1|
+ The result is negative (positive) if 'a', 'b', 'c' appear in
+counterclockwise (clockwise) order when viewed from 'd' or zero if all
+four points are coplanar.
+
+ The routine
+real insphere(triple a, triple b, triple c, triple d, triple e);
+returns a positive (negative) value if 'e' lies inside (outside) the
+sphere passing through points 'a,b,c,d' oriented so that
+'dot(cross(a-d,b-d),c-d)' is positive, or zero if all five points are
+cospherical. The value returned is the determinant
+|a.x a.y a.z a.x^2+a.y^2+a.z^2 1|
+|b.x b.y b.z b.x^2+b.y^2+b.z^2 1|
+|c.x c.y c.z c.x^2+c.y^2+c.z^2 1|
+|d.x d.y d.z d.x^2+d.y^2+d.z^2 1|
+|e.x e.y e.z e.x^2+e.y^2+e.z^2 1|
+
+ Here is an example showing all five guide3 connectors:
+import graph3;
+
+size(200);
+
+currentprojection=orthographic(500,-500,500);
+
+triple[] z=new triple[10];
+
+z[0]=(0,100,0); z[1]=(50,0,0); z[2]=(180,0,0);
+
+for(int n=3; n <= 9; ++n)
+ z[n]=z[n-3]+(200,0,0);
+
+path3 p=z[0]..z[1]---z[2]::{Y}z[3]
+&z[3]..z[4]--z[5]::{Y}z[6]
+&z[6]::z[7]---z[8]..{Y}z[9];
+
+draw(p,grey+linewidth(4mm),currentlight);
+
+xaxis3(Label(XY()*"$x$",align=-3Y),red,above=true);
+yaxis3(Label(XY()*"$y$",align=-3X),red,above=true);
+
+ [./join3]
+
+ Three-dimensional versions of bars or arrows can be drawn with one of
+the specifiers 'None', 'Blank', 'BeginBar3', 'EndBar3' (or equivalently
+'Bar3'), 'Bars3', 'BeginArrow3', 'MidArrow3', 'EndArrow3' (or
+equivalently 'Arrow3'), 'Arrows3', 'BeginArcArrow3', 'EndArcArrow3' (or
+equivalently 'ArcArrow3'), 'MidArcArrow3', and 'ArcArrows3'.
+Three-dimensional bars accept the optional arguments '(real size=0,
+triple dir=O)'. If 'size=O', the default bar length is used; if
+'dir=O', the bar is drawn perpendicular to the path and the initial
+viewing direction. The predefined three-dimensional arrowhead styles
+are 'DefaultHead3', 'HookHead3', 'TeXHead3'. Versions of the
+two-dimensional arrowheads lifted to three-dimensional space and aligned
+according to the initial viewpoint (or an optionally specified 'normal'
+vector) are also defined: 'DefaultHead2(triple normal=O)',
+'HookHead2(triple normal=O)', 'TeXHead2(triple normal=O)'. These are
+illustrated in the example 'arrows3.asy'.
+
+ Module 'three' also defines the three-dimensional margins
+'NoMargin3', 'BeginMargin3', 'EndMargin3', 'Margin3', 'Margins3',
+'BeginPenMargin2', 'EndPenMargin2', 'PenMargin2', 'PenMargins2',
+'BeginPenMargin3', 'EndPenMargin3', 'PenMargin3', 'PenMargins3',
+'BeginDotMargin3', 'EndDotMargin3', 'DotMargin3', 'DotMargins3',
+'Margin3', and 'TrueMargin3'.
+
+ The routine
+void pixel(picture pic=currentpicture, triple v, pen p=currentpen,
+ real width=1);
+can be used to draw on picture 'pic' a pixel of width 'width' at
+position 'v' using pen 'p'.
+
+ Further three-dimensional examples are provided in the files
+'near_earth.asy', 'conicurv.asy', and (in the 'animations' subdirectory)
+'cube.asy'.
+
+ Limited support for projected vector graphics (effectively
+three-dimensional nonrendered 'PostScript') is available with the
+setting 'render=0'. This currently only works for piecewise planar
+surfaces, such as those produced by the parametric 'surface' routines in
+the 'graph3' module. Surfaces produced by the 'solids' module will also
+be properly rendered if the parameter 'nslices' is sufficiently large.
+
+ In the module 'bsp', hidden surface removal of planar pictures is
+implemented using a binary space partition and picture clipping. A
+planar path is first converted to a structure 'face' derived from
+'picture'. A 'face' may be given to a two-dimensional drawing routine
+in place of any 'picture' argument. An array of such faces may then be
+drawn, removing hidden surfaces:
+void add(picture pic=currentpicture, face[] faces,
+ projection P=currentprojection);
+ Labels may be projected to two dimensions, using projection 'P', onto
+the plane passing through point 'O' with normal 'cross(u,v)' by
+multiplying it on the left by the transform
+transform transform(triple u, triple v, triple O=O,
+ projection P=currentprojection);
+
+ Here is an example that shows how a binary space partition may be
+used to draw a two-dimensional vector graphics projection of three
+orthogonal intersecting planes:
+size(6cm,0);
+import bsp;
+
+real u=2.5;
+real v=1;
+
+currentprojection=oblique;
+
+path3 y=plane((2u,0,0),(0,2v,0),(-u,-v,0));
+path3 l=rotate(90,Z)*rotate(90,Y)*y;
+path3 g=rotate(90,X)*rotate(90,Y)*y;
+
+face[] faces;
+filldraw(faces.push(y),project(y),yellow);
+filldraw(faces.push(l),project(l),lightgrey);
+filldraw(faces.push(g),project(g),green);
+
+add(faces);

+
+8.30 'graph3'
+=============
+
+This module implements three-dimensional versions of the functions in
+'graph.asy'. To draw an x axis in three dimensions, use the routine
+void xaxis3(picture pic=currentpicture, Label L="", axis axis=YZZero,
+ real xmin=-infinity, real xmax=infinity, pen p=currentpen,
+ ticks3 ticks=NoTicks3, arrowbar3 arrow=None, bool above=false);
+Analogous routines 'yaxis' and 'zaxis' can be used to draw y and z axes
+in three dimensions. There is also a routine for drawing all three
+axis:
+void axes3(picture pic=currentpicture,
+ Label xlabel="", Label ylabel="", Label zlabel="",
+ bool extend=false,
+ triple min=(-infinity,-infinity,-infinity),
+ triple max=(infinity,infinity,infinity),
+ pen p=currentpen, arrowbar3 arrow=None);
+
+The predefined three-dimensional axis types are
+axis YZEquals(real y, real z, triple align=O, bool extend=false);
+axis XZEquals(real x, real z, triple align=O, bool extend=false);
+axis XYEquals(real x, real y, triple align=O, bool extend=false);
+axis YZZero(triple align=O, bool extend=false);
+axis XZZero(triple align=O, bool extend=false);
+axis XYZero(triple align=O, bool extend=false);
+axis Bounds(int type=Both, int type2=Both, triple align=O, bool extend=false);
+The optional 'align' parameter to these routines can be used to specify
+the default axis and tick label alignments. The 'Bounds' axis accepts
+two type parameters, each of which must be one of 'Min', 'Max', or
+'Both'. These parameters specify which of the four possible
+three-dimensional bounding box edges should be drawn.
+
+ The three-dimensional tick options are 'NoTicks3', 'InTicks',
+'OutTicks', and 'InOutTicks'. These specify the tick directions for the
+'Bounds' axis type; other axis types inherit the direction that would be
+used for the 'Bounds(Min,Min)' axis.
+
+ Here is an example of a helix and bounding box axes with ticks and
+axis labels, using orthographic projection:
+import graph3;
+
+size(0,200);
+size3(200,IgnoreAspect);
+
+currentprojection=orthographic(4,6,3);
+
+real x(real t) {return cos(2pi*t);}
+real y(real t) {return sin(2pi*t);}
+real z(real t) {return t;}
+
+path3 p=graph(x,y,z,0,2.7,operator ..);
+
+draw(p,Arrow3);
+
+scale(true);
+
+xaxis3(XZ()*"$x$",Bounds,red,InTicks(Label,2,2));
+yaxis3(YZ()*"$y$",Bounds,red,InTicks(beginlabel=false,Label,2,2));
+zaxis3(XZ()*"$z$",Bounds,red,InTicks);
+
+ [./helix]
+
+ The next example illustrates three-dimensional x, y, and z axes,
+without autoscaling of the axis limits:
+import graph3;
+
+size(0,200);
+size3(200,IgnoreAspect);
+
+currentprojection=perspective(5,2,2);
+
+scale(Linear,Linear,Log);
+
+xaxis3("$x$",0,1,red,OutTicks(2,2));
+yaxis3("$y$",0,1,red,OutTicks(2,2));
+zaxis3("$z$",1,30,red,OutTicks(beginlabel=false));
+
+ [./axis3]
+
+ One can also place ticks along a general three-dimensional axis:
+import graph3;
+
+size(0,100);
+
+path3 g=yscale3(2)*unitcircle3;
+currentprojection=perspective(10,10,10);
+
+axis(Label("C",position=0,align=15X),g,InTicks(endlabel=false,8,end=false),
+ ticklocate(0,360,new real(real v) {
+ path3 h=O--max(abs(max(g)),abs(min(g)))*dir(90,v);
+ return intersect(g,h)[0];},
+ new triple(real t) {return cross(dir(g,t),Z);}));
+
+
+ [./generalaxis3]
+
+ Surface plots of matrices and functions over the region 'box(a,b)' in
+the XY plane are also implemented:
+surface surface(real[][] f, pair a, pair b, bool[][] cond={});
+surface surface(real[][] f, pair a, pair b, splinetype xsplinetype,
+ splinetype ysplinetype=xsplinetype, bool[][] cond={});
+surface surface(real[][] f, real[] x, real[] y,
+ splinetype xsplinetype=null, splinetype ysplinetype=xsplinetype,
+ bool[][] cond={})
+surface surface(triple[][] f, bool[][] cond={});
+surface surface(real f(pair z), pair a, pair b, int nx=nmesh, int ny=nx,
+ bool cond(pair z)=null);
+surface surface(real f(pair z), pair a, pair b, int nx=nmesh, int ny=nx,
+ splinetype xsplinetype, splinetype ysplinetype=xsplinetype,
+ bool cond(pair z)=null);
+surface surface(triple f(pair z), real[] u, real[] v,
+ splinetype[] usplinetype, splinetype[] vsplinetype=Spline,
+ bool cond(pair z)=null);
+surface surface(triple f(pair z), pair a, pair b, int nu=nmesh, int nv=nu,

+surface surface(triple f(pair z), pair a, pair b, int nu=nmesh, int nv=nu,
+ splinetype[] usplinetype, splinetype[] vsplinetype=Spline,
+ bool cond(pair z)=null);
+The final two versions draw parametric surfaces for a function f(u,v)
+over the parameter space 'box(a,b)', as illustrated in the example
+'parametricsurface.asy'. An optional splinetype 'Spline' may be
+specified. The boolean array or function 'cond' can be used to control
+which surface mesh cells are actually drawn (by default all mesh cells
+over 'box(a,b)' are drawn). Surface lighting is illustrated in the
+example files 'parametricsurface.asy' and 'sinc.asy'. Lighting can be
+disabled by setting 'light=nolight', as in this example of a Gaussian
+surface:
+import graph3;
+
+size(200,0);
+
+currentprojection=perspective(10,8,4);
+
+real f(pair z) {return 0.5+exp(-abs(z)^2);}

+draw((-1,-1,0)--(1,-1,0)--(1,1,0)--(-1,1,0)--cycle);
+
+draw(arc(0.12Z,0.2,90,60,90,25),ArcArrow3);
+
+surface s=surface(f,(-1,-1),(1,1),nx=5,Spline);

+draw(s,lightgray,meshpen=black+thick(),nolight,render(merge=true));
+
+label("$O$",O,-Z+Y,red);
+
+ [./GaussianSurface]
+A mesh can be drawn without surface filling by specifying 'nullpen' for
+the surfacepen.
+
+ A vector field of 'nu'\times'nv' arrows on a parametric surface 'f'
+over 'box(a,b)' can be drawn with the routine
+picture vectorfield(path3 vector(pair v), triple f(pair z), pair a, pair b,
+ int nu=nmesh, int nv=nu, bool truesize=false,
+ real maxlength=truesize ? 0 : maxlength(f,a,b,nu,nv),
+ bool cond(pair z)=null, pen p=currentpen,

+8.32 'solids'
+=============
+
+This solid geometry module defines a structure 'revolution' that can be
+used to fill and draw surfaces of revolution. The following example
+uses it to display the outline of a circular cylinder of radius 1 with
+axis 'O--1.5unit(Y+Z)' with perspective projection:
+import solids;
+
+size(0,100);
+
+revolution r=cylinder(O,1,1.5,Y+Z);
+draw(r,heavygreen);
+
+ [./cylinderskeleton]
+
+ Further illustrations are provided in the example files
+'cylinder.asy', 'cones.asy', 'hyperboloid.asy', and 'torus.asy'.
+
+ The structure 'skeleton' contains the three-dimensional wireframe
+used to visualize a volume of revolution:
+struct skeleton {
+ struct curve {
+ path3[] front;
+ path3[] back;
+ }
+ // transverse skeleton (perpendicular to axis of revolution)
+ curve transverse;
+ // longitudinal skeleton (parallel to axis of revolution)

+
+8.33 'tube'
+===========
+
+This module extends the 'tube' surfaces constructed in
+'three_arrows.asy' to arbitrary cross sections, colors, and spine
+transformations. The routine
+surface tube(path3 g, coloredpath section,
+ transform T(real)=new transform(real t) {return identity();},
+ real corner=1, real relstep=0);
+draws a tube along 'g' with cross section 'section', after applying the
+transformation 'T(t)' at 'point(g,t)'. The parameter 'corner' controls
+the number of elementary tubes at the angular points of 'g'. A nonzero
+value of 'relstep' specifies a fixed relative time step (in the sense of
+'relpoint(g,t)') to use in constructing elementary tubes along 'g'. The
+type 'coloredpath' is a generalization of 'path' to which a 'path' can
+be cast:
+struct coloredpath
+{
+ path p;
+ pen[] pens(real);
+ int colortype=coloredSegments;
+}
+Here 'p' defines the cross section and the method 'pens(real t)' returns
+an array of pens (interpreted as a cyclic array) used for shading the
+tube patches at 'relpoint(g,t)'. If 'colortype=coloredSegments', the
+tube patches are filled as if each segment of the section was colored
+with the pen returned by 'pens(t)', whereas if 'colortype=coloredNodes',
+the tube components are vertex shaded as if the nodes of the section
+were colored.
+
+ A 'coloredpath' can be constructed with one of the routines:
+coloredpath coloredpath(path p, pen[] pens(real),
+ int colortype=coloredSegments);
+coloredpath coloredpath(path p, pen[] pens=new pen[] {currentpen},
+ int colortype=coloredSegments);
+coloredpath coloredpath(path p, pen pen(real));
+In the second case, the pens are independent of the relative time. In
+the third case, the array of pens contains only one pen, which depends
+of the relative time.
+
+ The casting of 'path' to 'coloredpath' allows the use of a 'path'
+instead of a 'coloredpath'; in this case the shading behaviour is the
+default shading behavior for a surface.
+
+ An example of 'tube' is provided in the file 'trefoilknot.asy'.
+Further examples can be found at
+<http://www.piprime.fr/files/asymptote/tube/>.

+
+8.34 'flowchart'
+================
+
+This module provides routines for drawing flowcharts. The primary
+structure is a 'block', which represents a single block on the
+flowchart. The following eight functions return a position on the
+appropriate edge of the block, given picture transform 't':
+
+pair block.top(transform t=identity());
+pair block.left(transform t=identity());
+pair block.right(transform t=identity());
+pair block.bottom(transform t=identity());
+pair block.topleft(transform t=identity());
+pair block.topright(transform t=identity());
+pair block.bottomleft(transform t=identity());
+pair block.bottomright(transform t=identity());
+
+To obtain an arbitrary position along the boundary of the block in user
+coordinates, use:
+pair block.position(real x, transform t=identity());
+
+The center of the block in user coordinates is stored in 'block.center'
+and the block size in 'PostScript' coordinates is given by 'block.size'.
+
+A frame containing the block is returned by
+frame block.draw(pen p=currentpen);
+
+ The following block generation routines accept a Label, string, or
+frame for their object argument:
+
+"rectangular block with an optional header (and padding 'dx' around header and body):"
+ block rectangle(object header, object body, pair center=(0,0),
+ pen headerpen=mediumgray, pen bodypen=invisible,
+ pen drawpen=currentpen,
+ real dx=3, real minheaderwidth=minblockwidth,
+ real minheaderheight=minblockwidth,
+ real minbodywidth=minblockheight,
+ real minbodyheight=minblockheight);
+ block rectangle(object body, pair center=(0,0),
+ pen fillpen=invisible, pen drawpen=currentpen,

+
+"parallelogram block:"

+

+ block diamond(object body, pair center=(0,0),

+"rectangular block with rounded corners:"
+ block roundrectangle(object body, pair center=(0,0),
+ pen fillpen=invisible, pen drawpen=currentpen,

+
+"rectangular block with beveled edges:"
+ block bevel(object body, pair center=(0,0), pen fillpen=invisible,
+ pen drawpen=currentpen, real dh=5, real dw=5,
+ real minwidth=minblockwidth, real minheight=minblockheight);
+
+ To draw paths joining the pairs in 'point' with right-angled lines,
+use the routine:
+path path(pair point[] ... flowdir dir[]);
+The entries in 'dir' identify whether successive segments between the
+pairs specified by 'point' should be drawn in the 'Horizontal' or
+'Vertical' direction.
+
+ Here is a simple flowchart example (see also the example
+'controlsystem.asy'):
+
+size(0,300);
+
+import flowchart;

+
+8.35 'contour'
+==============
+
+This module draws contour lines. To construct contours corresponding to
+the values in a real array 'c' for a function 'f' on 'box(a,b)', use the
+routine
+guide[][] contour(real f(real, real), pair a, pair b,
+ real[] c, int nx=ngraph, int ny=nx,
+ interpolate join=operator --, int subsample=1);
+The integers 'nx' and 'ny' define the resolution. The default
+resolution, 'ngraph x ngraph' (here 'ngraph' defaults to '100') can be
+increased for greater accuracy. The default interpolation operator is
+'operator --' (linear). Spline interpolation ('operator ..') may
+produce smoother contours but it can also lead to overshooting. The
+'subsample' parameter indicates the number of interior points that
+should be used to sample contours within each '1 x 1' box; the default
+value of '1' is usually sufficient.
+
+ To construct contours for an array of data values on a uniform
+two-dimensional lattice on 'box(a,b)', use
+guide[][] contour(real[][] f, pair a, pair b, real[] c,
+ interpolate join=operator --, int subsample=1);
+
+ To construct contours for an array of data values on a nonoverlapping
+regular mesh specified by the two-dimensional array 'z',
+guide[][] contour(pair[][] z, real[][] f, real[] c,
+ interpolate join=operator --, int subsample=1);
+
+To construct contours for an array of values 'f' specified at
+irregularly positioned points 'z', use the routine
+guide[][] contour(pair[] z, real[] f, real[] c, interpolate join=operator --);
+The contours themselves can be drawn with one of the routines
+void draw(picture pic=currentpicture, Label[] L=new Label[],
+ guide[][] g, pen p=currentpen);
+
+void draw(picture pic=currentpicture, Label[] L=new Label[],
+ guide[][] g, pen[] p);
+
+ The following simple example draws the contour at value '1' for the
+function z=x^2+y^2, which is a unit circle:
+import contour;
+size(75);
+
+real f(real a, real b) {return a^2+b^2;}
+draw(contour(f,(-1,-1),(1,1),new real[] {1}));
+
+ [./onecontour]
+
+ The next example draws and labels multiple contours for the function
+z=x^2-y^2 with the resolution '100 x 100', using a dashed pen for
+negative contours and a solid pen for positive (and zero) contours:
+import contour;
+
+size(200);
+
+real f(real x, real y) {return x^2-y^2;}
+int n=10;
+real[] c=new real[n];
+for(int i=0; i < n; ++i) c[i]=(i-n/2)/n;
+
+pen[] p=sequence(new pen(int i) {
+ return (c[i] >= 0 ? solid : dashed)+fontsize(6pt);
+ },c.length);
+
+Label[] Labels=sequence(new Label(int i) {
+ return Label(c[i] != 0 ? (string) c[i] : "",Relative(unitrand()),(0,0),
+ UnFill(1bp));
+ },c.length);
+
+draw(Labels,contour(f,(-1,-1),(1,1),c),p);
+
+ [./multicontour]
+
+ The next example illustrates how contour lines can be drawn on color
+density images:
+import graph;
+import palette;
+import contour;
+
+size(10cm,10cm,IgnoreAspect);
+
+pair a=(0,0);
+pair b=(2pi,2pi);
+
+real f(real x, real y) {return cos(x)*sin(y);}
+
+int N=200;
+int Divs=10;
+int divs=2;
+
+defaultpen(1bp);
+pen Tickpen=black;
+pen tickpen=gray+0.5*linewidth(currentpen);
+pen[] Palette=BWRainbow();
+
+bounds range=image(f,Automatic,a,b,N,Palette);
+
+// Major contours
+
+real[] Cvals=uniform(range.min,range.max,Divs);
+draw(contour(f,a,b,Cvals,N,operator --),Tickpen);
+
+// Minor contours
+real[] cvals;
+for(int i=0; i < Cvals.length-1; ++i)
+ cvals.append(uniform(Cvals[i],Cvals[i+1],divs)[1:divs]);
+draw(contour(f,a,b,cvals,N,operator --),tickpen);
+
+xaxis("$x$",BottomTop,LeftTicks,above=true);
+yaxis("$y$",LeftRight,RightTicks,above=true);
+
+palette("$f(x,y)$",range,point(NW)+(0,0.5),point(NE)+(0,1),Top,Palette,
+ PaletteTicks(N=Divs,n=divs,Tickpen,tickpen));
+
+ [./imagecontour]
+
+ Finally, here is an example that illustrates the construction of
+contours from irregularly spaced data:
+import contour;
+
+size(200);
+
+int n=100;
+
+real f(real a, real b) {return a^2+b^2;}
+
+srand(1);
+
+real r() {return 1.1*(rand()/randMax*2-1);}
+
+pair[] points=new pair[n];
+real[] values=new real[n];
+
+for(int i=0; i < n; ++i) {
+ points[i]=(r(),r());
+ values[i]=f(points[i].x,points[i].y);
+}
+
+draw(contour(points,values,new real[]{0.25,0.5,1},operator ..),blue);
+
+ [./irregularcontour]
+
+ In the above example, the contours of irregularly spaced data are
+constructed by first creating a triangular mesh from an array 'z' of
+pairs:
+
+int[][] triangulate(pair[] z);
+
+size(200);
+int np=100;
+pair[] points;
+
+real r() {return 1.2*(rand()/randMax*2-1);}
+
+for(int i=0; i < np; ++i)
+ points.push((r(),r()));
+
+int[][] trn=triangulate(points);
+
+for(int i=0; i < trn.length; ++i) {
+ draw(points[trn[i][0]]--points[trn[i][1]]);
+ draw(points[trn[i][1]]--points[trn[i][2]]);
+ draw(points[trn[i][2]]--points[trn[i][0]]);
+}
+
+for(int i=0; i < np; ++i)
+ dot(points[i],red);
+
+ [./triangulate]
+
+ The example 'Gouraudcontour.asy' illustrates how to produce color
+density images over such irregular triangular meshes. 'Asymptote' uses
+a robust version of Paul Bourke's Delaunay triangulation algorithm based
+on the public-domain exact arithmetic predicates written by Jonathan
+Shewchuk.

+8.36 'contour3'
+===============
+
+This module draws surfaces described as the null space of real-valued
+functions of (x,y,z) or 'real[][][]' matrices. Its usage is illustrated
+in the example file 'magnetic.asy'.
+
+
+File: asymptote.info, Node: smoothcontour3, Next: slopefield, Prev: contour3, Up: Base modules
+
+8.37 'smoothcontour3'
+=====================
+
+This module, written by Charles Staats, draws implicitly defined
+surfaces with smooth appearance. The purpose of this module is similar
+to that of 'contour3': given a real-valued function f(x,y,z), construct
+the surface described by the equation f(x,y,z) = 0. The
+'smoothcontour3' module generally produces nicer results than
+'contour3', but takes longer to compile. Additionally, the algorithm
+assumes that the function and the surface are both smooth; if they are
+not, then 'contour3' may be a better choice.
+
+ To construct the null surface of a function 'f(triple)' or
+'ff(real,real,real)' over 'box(a,b)', use the routine
+surface implicitsurface(real f(triple)=null,
+ real ff(real,real,real)=null,
+ triple a,
+ triple b,
+ int n=nmesh,
+ bool keyword overlapedges=false,
+ int keyword nx=n,
+ int keyword ny=n,
+ int keyword nz=n,
+ int keyword maxdepth=8,
+ bool usetriangles=true);
+The optional parameter 'overlapedges' attempts to compensate for an
+artifact that can cause the renderer to "see through" the boundary
+between patches. Although it defaults to 'false', it should usually be
+set to 'true'. The example 'genustwo.asy' illustrates the use of this
+function. Additional examples, together with a more in-depth
+explanation of the module's usage and pitfalls, are available at
+<https://github.com/charlesstaats/smoothcontour3>.

+
+8.38 'slopefield'
+=================
+
+To draw a slope field for the differential equation dy/dx=f(x,y) (or
+dy/dx=f(x)), use:
+picture slopefield(real f(real,real), pair a, pair b,
+ int nx=nmesh, int ny=nx,
+ real tickfactor=0.5, pen p=currentpen,
+ arrowbar arrow=None);
+Here, the points 'a' and 'b' are the lower left and upper right corners
+of the rectangle in which the slope field is to be drawn, 'nx' and 'ny'
+are the respective number of ticks in the x and y directions,
+'tickfactor' is the fraction of the minimum cell dimension to use for
+drawing ticks, and 'p' is the pen to use for drawing the slope fields.
+The return value is a picture that can be added to 'currentpicture' via
+the 'add(picture)' command.
+
+ The function
+path curve(pair c, real f(real,real), pair a, pair b);
+takes a point ('c') and a slope field-defining function 'f' and returns,
+as a path, the curve passing through that point. The points 'a' and 'b'
+represent the rectangular boundaries over which the curve is
+interpolated.
+
+ Both 'slopefield' and 'curve' alternatively accept a function 'real
+f(real)' that depends on x only, as seen in this example:
+
+import slopefield;
+
+size(200);
+
+real func(real x) {return 2x;}
+add(slopefield(func,(-3,-3),(3,3),20,Arrow));
+draw(curve((0,0),func,(-3,-3),(3,3)),red);

+
+ All boolean options can be negated by prepending 'no' to the option
+name.
+
+ If no arguments are given, 'Asymptote' runs in interactive mode
+(*note Interactive mode::). In this case, the default output file is
+'out.eps'.
+
+ If '-' is given as the file argument, 'Asymptote' reads from standard
+input.
+
+ If multiple files are specified, they are treated as separate
+'Asymptote' runs.
+
+ If the string 'autoimport' is nonempty, a module with this name is
+automatically imported for each run as the final step in loading module
+'plain'.
+
+ Default option values may be entered as 'Asymptote' code in a
+configuration file named 'config.asy' (or the file specified by the
+environment variable 'ASYMPTOTE_CONFIG' or '-config' option).
+'Asymptote' will look for this file in its usual search path (*note
+Search paths::). Typically the configuration file is placed in the
+'.asy' directory in the user's home directory ('%USERPROFILE%\.asy'
+under 'MSDOS'). Configuration variables are accessed using the long
+form of the option names:
+import settings;
+outformat="pdf";
+batchView=false;
+interactiveView=true;
+batchMask=false;
+interactiveMask=true;
+ Command-line options override these defaults. Most configuration
+variables may also be changed at runtime. The advanced configuration
+variables 'dvipsOptions', 'hyperrefOptions', 'convertOptions',
+'gsOptions', 'htmlviewerOptions', 'psviewerOptions', 'pdfviewerOptions',
+'pdfreloadOptions', 'glOptions', and 'dvisvgmOptions' allow specialized
+options to be passed as a string to the respective applications or
+libraries. The default value of 'hyperrefOptions' is
+'setpagesize=false,unicode,pdfborder=0 0 0'.
+
+ If you insert
+import plain;
+settings.autoplain=true;
+at the beginning of the configuration file, it can contain arbitrary
+'Asymptote' code.
+
+ The default output format is EPS for the (default) 'latex' and 'tex'
+tex engine and PDF for the 'pdflatex', 'xelatex', 'context', 'luatex',
+and 'lualatex' tex engines. Alternative output formats may be produced
+using the '-f' option (or 'outformat' setting).
+
+ To produce SVG output, you will need 'dvisvgm' (version 2.6.3 or
+later) from <https://dvisvgm.de>. You might need to adjust the
+configuration variable 'libgs' to point to the location of your
+'Ghostscript' library 'libgs.so' (or to an empty string, depending on
+how 'dvisvgm' was configured). The 2.9.1 version of 'dvisvgm' can
+display SVG output (used by the 'xasy' editor) for embedded EPS, PDF,
+PNG, and JPEG images included with the 'graphic()' function.
+
+ 'Asymptote' can also produce any output format supported by the
+'ImageMagick' 'convert' program (version 6.3.5 or later recommended; an
+'Invalid Parameter' error message indicates that the 'MSDOS' utility
+'convert' is being used instead of the one that comes with
+'ImageMagick'). The optional setting '-render n' requests an output
+resolution of 'n' pixels per 'bp'. Antialiasing is controlled by the
+parameter 'antialias', which by default specifies a sampling width of 2
+pixels. To give other options to 'convert', use the 'convertOptions'
+setting or call convert manually. This example emulates how 'Asymptote'
+produces antialiased 'tiff' output at one pixel per 'bp':
+asy -o - venn | convert -alpha Off -density 144x144 -geometry 50%x eps:- venn.tiff
+
+ If the option '-nosafe' is given, 'Asymptote' runs in unsafe mode.
+This enables the 'int system(string s)' and 'int system(string[] s)'
+calls, allowing one to execute arbitrary shell commands. The default
+mode, '-safe', disables this call.
+
+ A 'PostScript' offset may be specified as a pair (in 'bp' units) with
+the '-O' option:
+asy -O 0,0 file
+The default offset is zero. The pair 'aligndir' specifies an optional
+direction on the boundary of the page (mapped to the rectangle
+[-1,1]\times[-1,1]) to which the picture should be aligned; the default
+value '(0,0)' species center alignment.
+
+ The '-c' ('command') option may be used to execute arbitrary
+'Asymptote' code on the command line as a string. It is not necessary
+to terminate the string with a semicolon. Multiple '-c' options are
+executed in the order they are given. For example
+asy -c 2+2 -c "sin(1)" -c "size(100); draw(unitsquare)"
+produces the output
+4
+0.841470984807897
+and draws a unitsquare of size '100'.
+
+ The '-u' ('user') option may be used to specify arbitrary 'Asymptote'
+settings on the command line as a string. It is not necessary to
+terminate the string with a semicolon. Multiple '-u' options are
+executed in the order they are given. Command-line code like '-u
+x=sqrt(2)' can be executed within a module like this:
+real x;
+usersetting();
+write(x);
+
+ When the '-l' ('listvariables') option is used with file arguments,
+only global functions and variables defined in the specified file(s) are
+listed.
+
+ Additional debugging output is produced with each additional '-v'
+option:
+'-v'
+ Display top-level module and final output file names.
+'-vv'
+ Also display imported and included module names and final 'LaTeX'
+ and 'dvips' processing information.
+'-vvv'
+ Also output 'LaTeX' bidirectional pipe diagnostics.
+'-vvvv'
+ Also output knot guide solver diagnostics.
+'-vvvvv'
+ Also output 'Asymptote' traceback diagnostics.

+
+10 Interactive mode
+*******************
+
+Interactive mode is entered by executing the command 'asy' with no file
+arguments. When the '-multiline' option is disabled (the default), each
+line must be a complete 'Asymptote' statement (unless explicitly
+continued by a final backslash character '\'); it is not necessary to
+terminate input lines with a semicolon. If one assigns
+'settings.multiline=true', interactive code can be entered over multiple
+lines; in this mode, the automatic termination of interactive input
+lines by a semicolon is inhibited. Multiline mode is useful for cutting
+and pasting 'Asymptote' code directly into the interactive input buffer.
+
+ Interactive mode can be conveniently used as a calculator:
+expressions entered at the interactive prompt (for which a corresponding
+'write' function exists) are automatically evaluated and written to
+'stdout'. If the expression is non-writable, its type signature will be
+printed out instead. In either case, the expression can be referred to
+using the symbol '%' in the next line input at the prompt. For example:
+> 2+3
+5
+> %*4
+20
+> 1/%
+0.05
+> sin(%)
+0.0499791692706783
+> currentpicture
+<picture currentpicture>
+> %.size(200,0)
+>
+
+ The '%' symbol, when used as a variable, is shorthand for the
+identifier 'operator answer', which is set by the prompt after each
+written expression evaluation.
+
+ The following special commands are supported only in interactive mode
+and must be entered immediately after the prompt:
+
+'help'
+ view the manual;
+'erase'
+ erase 'currentpicture';
+'reset'
+ reset the 'Asymptote' environment to its initial state, except for
+ changes to the settings module (*note settings::), the current
+ directory (*note cd::), and breakpoints (*note Debugger::);
+'input FILE'
+ does an interactive reset, followed by the command 'include FILE'.
+ If the file name 'FILE' contains nonalphanumeric characters,
+ enclose it with quotation marks. A trailing semi-colon followed by
+ optional 'Asymptote' commands may be entered on the same line.
+'quit'
+ exit interactive mode ('exit' is a synonym; the abbreviation 'q' is
+ also accepted unless there exists a top-level variable named 'q').
+ A history of the most recent 1000 (this number can be changed with
+ the 'historylines' configuration variable) previous commands will
+ be retained in the file '.asy/history' in the user's home directory
+ (unless the command-line option '-localhistory' was specified, in
+ which case the history will be stored in the file '.asy_history' in
+ the current directory).
+
+ Typing 'ctrl-C' interrupts the execution of 'Asymptote' code and
+returns control to the interactive prompt.
+
+ Interactive mode is implemented with the GNU 'readline' library, with
+command history and auto-completion. To customize the key bindings,
+see: <https://tiswww.case.edu/php/chet/readline/readline.html>
+
+ The file 'asymptote.py' in the 'Asymptote' system directory provides
+an alternative way of entering 'Asymptote' commands interactively,
+coupled with the full power of 'Python'. Copy this file to your 'Python
+path' and then execute from within 'Python 3' the commands
+from asymptote import *
+g=asy()
+g.size(200)
+g.draw("unitcircle")
+g.send("draw(unitsquare)")
+g.fill("unitsquare, blue")
+g.clip("unitcircle")
+g.label("\"$O$\", (0,0), SW")

+11 Graphical User Interface
+***************************
+
+* Menu:
+
+* GUI installation:: Installing 'xasy'
+* GUI usage:: Using 'xasy' to edit objects
+
+In the event that adjustments to the final figure are required, the
+preliminary Graphical User Interface (GUI) 'xasy' included with
+'Asymptote' allows you to move graphical objects and draw new ones. The
+modified figure can then be saved as a normal 'Asymptote' file.
+
+
+File: asymptote.info, Node: GUI installation, Next: GUI usage, Prev: GUI, Up: GUI
+
+11.1 GUI installation
+=====================
+
+As 'xasy' is written in the interactive scripting language 'Python/Qt',
+it requires 'Python' (<https://www.python.org>), along with the 'Python'
+packages 'pyqt5', 'cson', and 'numpy':
+
+pip3 install cson numpy pyqt5 PyQt5.sip
+
+ Pictures are deconstructed into the SVG image format. Since 'Qt5'
+does not support 'SVG' clipping, you will need the 'rsvg-convert'
+utility, which is part of the 'librsvg2-tools' package on 'UNIX' systems
+and the 'librsvg' package on 'MacOS X'; under 'Microsoft Windows', it is
+available as
+
+ <https://sourceforge.net/projects/tumagcc/files/rsvg-convert-2.40.20.7z>
+
+
+File: asymptote.info, Node: GUI usage, Prev: GUI installation, Up: GUI
+
+11.2 GUI usage
+==============
+
+The arrow keys (or mouse wheel) are convenient for temporarily raising
+and lowering objects within 'xasy', allowing an object to be selected.
+Pressing the arrow keys will pan while the shift key is held and zoom
+while the control key is held. The mouse wheel will pan while the alt
+or shift keys is held and zoom while the control key is held. In
+translate mode, an object can be dragged coarsely with the mouse or
+positioned finely with the arrow keys while holding down the mouse
+button.
+
+ Deconstruction of compound objects (such as arrows) can be prevented
+by enclosing them within the commands
+void begingroup(picture pic=currentpicture);
+void endgroup(picture pic=currentpicture);
+ By default, the elements of a picture or frame will be grouped
+together on adding them to a picture. However, the elements of a frame
+added to another frame are not grouped together by default: their
+elements will be individually deconstructed (*note add::).
+
+

+
+12 'PostScript' to 'Asymptote'
+******************************
+
+The excellent 'PostScript' editor 'pstoedit' (version 3.50 or later;
+available from <https://sourceforge.net/projects/pstoedit/>) includes an
+'Asymptote' backend. Unlike virtually all other 'pstoedit' backends,
+this driver includes native clipping, even-odd fill rule, 'PostScript'
+subpath, and full image support. Here is an example: 'asy -V
+/usr/local/share/doc/asymptote/examples/venn.asy'
+pstoedit -f asy venn.eps test.asy
+asy -V test
+
+If the line widths aren't quite correct, try giving 'pstoedit' the
+'-dis' option. If the fonts aren't typeset correctly, try giving
+'pstoedit' the '-dt' option.

+13 Help
+*******
+
+A list of frequently asked questions (FAQ) is maintained at
+ <https://asymptote.sourceforge.io/FAQ>
+Questions on installing and using 'Asymptote' that are not addressed in
+the FAQ should be sent to the 'Asymptote' forum:
+ <https://sourceforge.net/p/asymptote/discussion/409349>
+Including an example that illustrates what you are trying to do will
+help you get useful feedback. 'LaTeX' problems can often be diagnosed
+with the '-vv' or '-vvv' command-line options. Contributions in the
+form of patches or 'Asymptote' modules can be posted here:
+ <https://sourceforge.net/p/asymptote/patches>
+To receive announcements of upcoming releases, please subscribe to
+'Asymptote' at
+ <https://sourceforge.net/projects/asymptote/>
+If you find a bug in 'Asymptote', please check (if possible) whether the
+bug is still present in the latest 'git' developmental code (*note
+Git::) before submitting a bug report. New bugs can be reported at
+ <https://github.com/vectorgraphics/asymptote/issues>
+To see if the bug has already been fixed, check bugs with Status
+'Closed' and recent lines in
+ <https://asymptote.sourceforge.io/ChangeLog>
+
+ 'Asymptote' can be configured with the optional GNU library
+'libsigsegv', available from <https://www.gnu.org/software/libsigsegv/>,
+which allows one to distinguish user-generated 'Asymptote' stack
+overflows (*note stack overflow::) from true segmentation faults (due to
+internal C++ programming errors; please submit the 'Asymptote' code that
+generates such segmentation faults along with your bug report).

+
+14 Debugger
+***********
+
+Asymptote now includes a line-based (as opposed to code-based) debugger
+that can assist the user in following flow control. To set a break
+point in file 'file' at line 'line', use the command
+
+void stop(string file, int line, code s=quote{});
+The optional argument 's' may be used to conditionally set the variable
+'ignore' in 'plain_debugger.asy' to 'true'. For example, the first 10
+instances of this breakpoint will be ignored (the variable 'int count=0'
+is defined in 'plain_debugger.asy'):
+stop("test",2,quote{ignore=(++count <= 10);});
+
+ To set a break point in file 'file' at the first line containing the
+string 'text', use
+
+void stop(string file, string text, code s=quote{});
+To list all breakpoints, use:
+void breakpoints();
+To clear a breakpoint, use:
+void clear(string file, int line);
+To clear all breakpoints, use:
+void clear();
+
+ The following commands may be entered at the debugging prompt:
+
+'h'
+ help;
+'c'
+ continue execution;
+
+'i'
+ step to the next instruction;
+
+'s'
+ step to the next executable line;
+
+'n'
+ step to the next executable line in the current file;
+
+'f'
+ step to the next file;
+
+'r'
+ return to the file associated with the most recent breakpoint;
+
+'t'
+ toggle tracing ('-vvvvv') mode;
+
+'q'
+ quit debugging and end execution;
+
+'x'
+ exit the debugger and run to completion.
+
+Arbitrary 'Asymptote' code may also be entered at the debugging prompt;
+however, since the debugger is implemented with 'eval', currently only
+top-level (global) variables can be displayed or modified.
+
+ The debugging prompt may be entered manually with the call
+void breakpoint(code s=quote{});

+.TH XASY 1x "27 Nov 2007"
+.SH NAME
+asy \- script-based vector graphics language
+.SH SYNOPSIS
+.B xasy
+.RI " [-x magnification] [filename]"
+.SH DESCRIPTION
+\fBAsymptote\fP is a powerful descriptive vector graphics language for
+technical drawing, inspired by MetaPost but with an improved C++\-like syntax.
+Asymptote provides for figures the same high\-quality level of typesetting that
+LaTeX does for scientific text.
+.PP
+\fBxasy\fP is a GUI for Asymptote that allows for final figure adjustments.
+
+.SH OPTIONS
+.TP
+.B \-x magnification
+Initial zoom.
+
+.SH SEE ALSO
+Asymptote and xasy are documented fully in the Asymptote Info page.
+.SH AUTHOR
+Asymptote was written by Andy Hammerlindl, John Bowman, and Tom Prince.
+.PP
+This manual page was written by Hubert Chan for the Debian project (but may
+be used by others).

+ (aside from the initial '-') are option characters. If `getopt'
+ is called repeatedly, it returns successively each of the option characters
+ from each of the option elements.
+
+ If `getopt' finds another option character, it returns that character,
+ updating `optind' and `nextchar' so that the next call to `getopt' can
+ resume the scan with the following option character or ARGV-element.
+
+ If there are no more option characters, `getopt' returns -1.
+ Then `optind' is the index in ARGV of the first ARGV-element
+ that is not an option. (The ARGV-elements have been permuted
+ so that those that are not options now come last.)
+
+ OPTSTRING is a string containing the legitimate option characters.
+ If an option character is seen that is not listed in OPTSTRING,
+ return '?' after printing an error message. If you set `opterr' to
+ zero, the error message is suppressed but we still return '?'.
+
+ If a char in OPTSTRING is followed by a colon, that means it wants an arg,
+ so the following text in the same ARGV-element, or the text of the following
+ ARGV-element, is returned in `optarg'. Two colons mean an option that
+ wants an optional arg; if there is text in the current ARGV-element,
+ it is returned in `optarg', otherwise `optarg' is set to zero.
+
+ If OPTSTRING starts with `-' or `+', it requests different methods of
+ handling the non-option ARGV-elements.
+ See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
+
+ Long-named options begin with `--' instead of `-'.
+ Their names may be abbreviated as long as the abbreviation is unique
+ or is an exact match for some defined option. If they have an
+ argument, it follows the option name in the same ARGV-element, separated
+ from the option name by a `=', or else the in next ARGV-element.
+ When `getopt' finds a long-named option, it returns 0 if that option's
+ `flag' field is nonzero, the value of the option's `val' field
+ if the `flag' field is zero.
+
+ The elements of ARGV aren't really const, because we permute them.
+ But we pretend they're const in the prototype to be compatible
+ with other systems.
+
+ LONGOPTS is a vector of `struct option' terminated by an
+ element containing a name which is zero.
+
+ LONGIND returns the index in LONGOPT of the long-named option found.
+ It is only valid when a long-named option has been found by the most
+ recent call.
+
+ If LONG_ONLY is nonzero, '-' as well as '--' can introduce

+
+The file gc-7.0nomem.patch avoids segmentation faults with gc-7.0 on
+out-of-memory errors.
+
+The file cygwin_freeglut-3.0.0.patch fixes undefined symbols when compiling the
+freeglut library statically under cygwin.
+
+The file fixmem.reg patches the Microsoft Windows registry so that the
+cygwin1.dll library can allocate more than 384MB. It is applied
+automatically by the Asymptote setup.exe file but may also be applied manually:
+regedit /s fixmem.reg
+
+The file gl-matrix-2.4.0-pruned.patch is used to build the required subset of
+the gl-matrix library. \ No newline at end of file

+ *
+ * This library allows one to render arbitrarily large images with OpenGL.
+ * The basic idea is to break the image into tiles which are rendered one
+ * at a time. The tiles are assembled together to form the final, large
+ * image. Tiles and images can be of any size.
+ *
+ * Basic usage:
+ *
+ * 1. Allocate a tile rendering context:
+ * TRcontext t = trNew();
+ *
+ * 2. Specify the final image buffer and tile size:
+ * GLubyte image[W][H][4]
+ * trImageSize(t, W, H);
+ * trImageBuffer(t, GL_RGBA, GL_UNSIGNED_BYTE, (GLubyte *) image);
+ *
+ * 3. Setup your projection:
+ * trFrustum(t, left, right, bottom top, near, far);
+ * or
+ * trOrtho(t, left, right, bottom top, near, far);
+ * or
+ * trPerspective(t, fovy, aspect, near, far);
+ *
+ * 4. Render the tiles:
+ * do {
+ * trBeginTile(t);
+ * DrawMyScene();
+ * } while (trEndTile(t));
+ *
+ * You provide the DrawMyScene() function which calls glClear() and
+ * draws all your stuff.
+ *
+ * 5. The image array is now complete. Display it, write it to a file, etc.
+ *
+ * 6. Delete the tile rendering context when finished:
+ * trDelete(t);
