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 is an average of 100 hits a day on the site. Go look at the online list of what's in this volume to see if it's for you. Highlights (for me) include an IEEE fast square root, uniform random rotations, triangle-cube intersection, and BSP tree ray tracing. There's tons more.
