A PostScript manual for mathematicians. This is a text for a course at UBC on Euclidean Geometry! The theme of the course is how to use computers to produce clear demonstrations in mathematics, but along the way it provides a complete introduction to PostScript.
Putting labels in PostScript figures. When asked what irks them most about trying to include good illustrations in mathematical papers, most mathematicians complain about the difficulty of adding mathematical labels. This is one solution, although admittedly somewhat intricate.
Dealing with colour. Colours on computer screens, and p[articularly inside a browser, are not perfect. This gives you some idea of what to expect.
DVIPS. The manual for dvips in .pdf format.
Byrne's Euclid. A beautiful if eccentric example of how to explain mathematical ideas with illustrations.
A review of Edward Tufte's book Visual Explanations (from the American Mathematical Society Notices of January 1999). Tufte's books are aimed at a general audience, but have something to offer to mathematicians. Including an example of how to use illustrations to make a mathematical argument.
Java image applets. To publish mathematics on the Internet, a variety of figure manipulations is necessary. Here is the beginning of a collection of tools for doing that.
A PostScript drawing toy. This will expand to a general tool for working interactively to produce PostScript figures.
