## Mathematical graphics

We intend to provide here a collection of tools
for producing graphics in
mathematical exposition, both in papers and on the Internet.
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.
