This manual is for `sketch', version 0.2 (build 131),
Saturday, August 09, 2008, a program that converts descriptions of simple
three-dimensional scenes into static drawings. This version generates
`PSTricks' or `PGF/TikZ' code suitable for use with the
TeX document processing system.

<p><code>Sketch</code> is a small, simple system for producing line drawings of
two- or three-dimensional objects and scenes.  It began as a way to
make illustrations for a textbook after we could find no suitable
tool for this purpose.  Existing scene processors emphasized GUIs
and/or photo-realism, both un-useful to us.  We wanted to produce
finely wrought, mathematically-based illustrations with no extraneous
detail.

   <p><code>Sketch</code> accepts a tiny scene description language and generates
<code>PSTricks</code> or <code>TikZ/PGF</code> code for LaTeX.  The
<code>sketch</code> language is similar to <code>PSTricks</code>, making it easy
to learn for current <code>PSTricks</code> users.  See
<a name="index-PSTricks-1"></a><tt>www.pstricks.de</tt> for information on <code>PSTricks</code>. 
<code>TikZ/PGF</code> are also very similar except for details of syntax. 
See
<a name="index-TikZ_002fPGF-2"></a><tt>http://sourceforge.net/projects/pgf</tt>.  One can easily lay raw
<code>PSTricks</code> or <code>TikZ/PGF</code> output over, in, or under
<code>sketch</code> drawings, providing the full power of LaTeX text and
mathematics formatting in a three-dimensional setting.
