Sketch
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.
Sketch
accepts a tiny scene description language and generates
PSTricks
or TikZ/PGF
code for LaTeX. The
sketch
language is similar to PSTricks
, making it easy
to learn for current PSTricks
users. See
www.pstricks.de for information on PSTricks
.
TikZ/PGF
is similar.
See
http://sourceforge.net/projects/pgf. One can easily include
arbitrary
PSTricks
or TikZ/PGF
drawings and text
over, in, or under
sketch
drawings, providing access to the full power of LaTeX
text and mathematics formatting in a three-dimensional setting.
