Sketch is a simple system for producing line drawings of
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 and be able to easily overlay TeX math and text. The input
language is reminiscent of PSTricks, so will be easy to learn for
current PSTricks users. It generates either PSTricks or TikZ/PGF
code as output. See http://www.frontiernet.net/~eugene.ressler .
