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. - -\comment ###################################################################### - -\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 - -\comment ##################################################################### - -\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. - -\comment ##################################################################### - -\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.

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. - -\comment ##################################################################### - -\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.

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"+'\\';. - - -File: asy-faq.info, Node: Question 2.10, Next: Question 2.11, Previous: Question 2.9, Up: Section 2 - -Question 2.10.

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. - - -File: asy-faq.info, Node: Question 8.3, Next: Question 8.4, Previous: Question 8.2, Up: Section 8 - -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. - - -File: asy-faq.info, Node: Question 8.4, Next: Question 8.5, Previous: Question 8.3, Up: Section 8 - -Question 8.4.

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. - - -File: asy-faq.info, Node: Question 8.7, Next: Question 8.8, Previous: Question 8.6, Up: Section 8 - -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.) - - -File: asy-faq.info, Node: Question 8.8, Next: Question 8.9, Previous: Question 8.7, Up: Section 8 - -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 - -File: asy-faq.info, Node: Question 8.9, Next: Question 9.1, Previous: Question 8.8, Up: Section 8 - -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.
