Request a sales quote"The GRAPHICS GEMS Series" was started in 1990 by Andrew Glassner. The vision and purpose of the Series was - and still is - to provide tips, techniques, and algorithms for graphics programmers. All of the gems are written by programmers who work in the field and are motivated by a common desire to share interesting ideas and tools with their colleagues. Each volume provides a new set of innovative solutions to a variety of programming problems.

Andrew S. Glassner
Andrew Glassner's contributions to computer graphics span 20 years. His work at Microsoft Research, Xerox PARC, the IBM Watson Research Labs, Bell Communications Research, and the Delft University of Technology has produced numerous technical articles on rendering theory and practice, animation, modeling, and new media. He currently creates new computer graphics tools at Microsoft Research. Among his recent work is Chicken Crossing, a 3D animated short film that has been shown internationally at film festivals and on television, and Dead Air, an interactive game for play over the Internet. Dr. Glassner is the author of the two volume bible, Principles of Digital Image Synthesis and 3D Computer Graphics: A Handbook for Artists and Designers. He has also edited An Introduction to Ray Tracing, and created the Graphics Gems series for programmers.
