The goal will be to describe how to implement a classic rigid-body physics engine. And there will be source code to go with it, illustrating a generic collision detection system to go with the collision response people seem to associate with a physics engine. I will also include a new section on ragdoll physics, and there will be source code to go with this. -- I plan on inserting a new chapter (chapter 6 below) that will contain descriptions of various papers of interest in game physics. In particular, I will review publications by Ronald Fedkiw, Jos Stam, and James O'Brien, choosing a few of each to describe and to implement in source code and include on the CDROM for the book. This new material fills the void in the 1st edition -- not much discussion of applications of particle systems, fluids, or gases. The chapter on shader programs (old Chapter 6) will be discarded in its entirety. -- Chapters 7 through 10 and Appendices A through D form the mathematical heart of the book. The appendices are effectively background material that a reader will be exposed to at a university. The chapters 7 through 10 are more advanced topics. I believe it is reasonable to break the book into two parts: -- Part I -The Physics -- -- 1 Introduction -- 2 Basic Concepts -- 3 Rigid Bodies -- 4 Deformable Bodies -- 5 Physics Engines [rigid body

• 摘要註: Create physically realistic 3D Graphics environments with this introduction to the ideas and techniques behind the process. Author David H. Eberly 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. The 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. This book even describes when real physics isn't necessary - and hacked physics will do. - CD-ROM with extensive C++ source code that supports physical simulation; has many illustrative applications for Windows, Linux, and OS X; and is compatible with many game engines - including the Wild Magic engine, for which the complete source code is included. - Includes exercises for instructional use and review of essential mathematics. - Revised and updated to include a new chapter about fluid dynamics based on the Navier-Stokes equations. The CD-ROM contains implementations that run in real time using the graphics hardware. The chapter on physics engines was rewritten to include new sections on the physics tick, on multithreaded and multiprocessor collision culling, and on velocity-based dynamics.
