I'm the archivist for the free Graphics Gems code base on the web. I do it for free, because this code is so valuable. Others think so, too: there are 100 hits a day on average at the site. Go look at the online list of what's in this volume to see if it's for you.

Highlights in this volume (for me - everyone's favorites vary) include an implementation of Perlin's noise function, a guide to quaternions, some useful C macros for vector ops (wonderfully short and clever), and view correlation.
