By David Eberly, 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, Netlmmerse. His background includes a BA in Mathematics from Bloomsburg U, MS and PhD degrees in Mathematics
from the U of Colorado at Boulder, and MS and PhD degrees in computer science from the U of North Carolina at Chapel Hill.
Dave Eberly's 3D Game Engine Design was the first professional guide to the essential concepts and algorithms of real-time
3D engines and quickly became a classic of game development. Dave's new book 3D Game Engine Architecture continues the
tradition with a comprehensive look at the software engineering and programming of 3D engines.
This book is a complete guide
to the engineering process, starting with a walk-through of the graphics pipeline showing how to construct the core elements of 3D systems,
including data structures, the math system, and the object system. Dave explains how to manage data with scene graphs, how to build rendering
and camera systems, and how to handle level of detail, terrain, and animation.
Advanced rendering effects such as vertex and
pixel shaders are also covered as well as collision detection and physics systems. The book concludes with a discussion of application
design, development tools, and coding standards for the source code of the new version of the Wild Magic engine included on the CD-ROM.
Wild Magic is a commercial-quality game engine used by many companies and is a unique resource for the game development community.
Audience
Professionals or students working in game development, simulation, scientific visualization, or virtual worlds.
