3D games

Real time rendering and software technology

Fabio Policarpo, Alan Watt

800 pages, parution le 01/11/2000

Résumé

With this book, authors Watt and Policarpo introduce the theory behind the design of computer games and detail advanced techniques used in the industry, such as: physically based animation; advanced scene management; pre-calculation techniques/image-based rendering; advanced motion capture; and artificial intelligence. Readers will be able to develop their own games within the games "skeletons" accompanying the book, and will learn how to program complex games. The book is divided into six parts: Foundations (which covers the foundations of 3D computer graphics), Classical 3D Graphics, Real-Time Rendering, Control of Objects, 2D Technology, and Software Technology. An appendix on Fly3D SDK Tutorials is also included, and the accompanying CD contains the Fly3D SDK games engine. This books is appropriate for programmers who want to be able to develop their own computer games.
