## About the author

### David Eberly

Dave Eberly is the president of Geometric Tools, Inc. (

*www.geometrictools.com*), a company that specializes in software development for computer graphics, image analysis, and numerical methods. Previously, he was the director of engineering at Numerical Design Ltd. (NDL), the company responsible for the real-time 3D game engine, NetImmerse. He also worked for NDL on Gamebryo, which was the next-generation engine after NetImmerse. His background includes a BA degree in mathematics from Bloomsburg University, MS and PhD degrees in mathematics from the University of Colorado at Boulder, and MS and PhD degrees in computer science from the University of North Carolina at ChapelHill. He is the author of**3D Game Engine Design, 2nd Edition**(2006),**3D Game Engine Architecture**(2005),**Game Physics**(2004), and coauthor with Philip Schneider of**Geometric Tools for Computer Graphics**(2003), all published by Morgan Kaufmann. As a mathematician, Dave did research in the mathematics of combustion, signal and image processing, and length-biased distributions in statistics. He was an associate professor at the University of Texas at San Antonio with an adjunct appointment in radiology at the U.T. Health Science Center at San Antonio. In 1991, he gave up his tenured position to re-train in computer science at the University of North Carolina. After graduating in 1994, he remained for one year as a research associate professor in computer science with a joint appointment in the Department of Neurosurgery, working in medical image analysis. His next stop was the SAS Institute, working for a year on SAS/Insight, a statistical graphics package. Finally, deciding that computer graphics and geometry were his real calling, Dave went to work for NDL (which is now Emergent Game Technologies), then to Magic Software, Inc., which later became Geometric Tools, Inc.

## Reviews

"I keep at most a dozen reference texts within easy reach of my workstation computer. This book will replace two of them."—Ian Ashdown, President, byHeart Consultants Limited

"Implementing physical simulations for real-time games is a complex task that requires a solid understanding of a wide range of concepts from the fields of mathematics and physics. Previously, the relevant information could only be gleaned through obscure research papers. Thanks to

"Eppur si muove . . . and yet it moves. From Galileo to game development, this book will surely become a standard reference for modeling movement." —Ian Ashdown, President, byHeart Consultants Limited

"This is an excellent companion volume to Dave's earlier

**Game Physics**, all this information is now available in a single, easily accessible volume. Dave has yet again produced a must-have book for game technology programmers everywhere." —Christer Ericson, Technology Lead, Sony Computer Entertainment"

**Game Physics**is a comprehensive reference of physical simulation techniques relevant to games and also contains a clear presentation of the mathematical background concepts fundamental to most types of game programming. I wish I had this book years ago." —Naty Hoffman, Senior Software Engineer, Naughty Dog, Inc."Eppur si muove . . . and yet it moves.

"This is an excellent companion volume to Dave's earlier

**3D Game Engine Design**. It shares the approach and strengths of his previous book. He doesn't try to pare down to the minimum necessary information that would allow you to build something with no more than basic functionality. Instead, he gives you all you need to begin working on a professional-caliber system. He puts the concepts firmly in context with current, ongoing research, so you have plenty of guidance on where to go if you are inclined to add even more features on your own. This is not a cookbook—it's a concise presentation of all the basic concepts needed to understand and use physics in
