Game Physics. (Morgan Kaufmann Series in Interactive 3D Technology) [Englisch] [Gebundene Ausgabe]

"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 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. 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 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 a modern game engine. It gives you a firm foundation you can use either to build a complete engine of your own or to understand what's going on inside the new powerful middleware physics engines available today. This book, especially when coupled with Dave's 3D Game Engine Design, provides the most complete resource of the mathematics relevant to modern 3D games that I can imagine. Along with clear descriptions of the mathematics and algorithms needed to create a powerful physics engine are sections covering pretty much all of the math you will encounter anywhere in the game-quaternions, linear algebra, and calculus." -Peter Lipson, Senior Programmer, Toys For Bob "This comprehensive introduction to the field of game physics will be invaluable to anyone interested in the increasingly more important aspect of video game production, namely, striving to achieve realism. Drawing from areas such as robotics, dynamic simulation, mathematical modeling, and control theory, this book succeeds in presenting the material in a concise and cohesive way. As a matter of fact, it can be recommended not only to video game professionals but also to students and practitioners of the above-mentioned disciplines." -Pal-Kristian Engstad, Senior Software Engineer, Naughty Dog, Inc. "Increases in processor power now make it feasible to run complex physical simulations in real time, which greatly increases their practical importance. Thus there is an increasing need for books like David Eberly's Game Physics that can give graphics programmers a grounding in the physical principles that underlie realistic computer animation." - W.Lewis Johnson --Physics Today

Game Physics is an introduction to the ideas and techniques needed to create physically realistic 3D graphic environments. As a companion volume to Dave Eberly's industry standard 3D Game Engine Design, Game Physics shares a similar practical approach and format. Dave includes simulations to introduce the key problems involved and then gradually reveals the mathematical and physical concepts needed to solve them. He then describes all the algorithmic foundations and uses code examples and working source code to show how they are implemented, culminating in a large collection of physical simulations. This book tackles the complex, challenging issues that other books avoid, including Lagrangian dynamics, rigid body dynamics, impulse methods, resting contact, linear complementarity problems, deformable bodies, mass-spring systems, friction, numerical solution of differential equations, numerical stability and its relationship to physical stability, and Verlet integration methods. Dave even describes when real physics isn't necessary—and hacked physics will do.
