3D Graphics for Game Programming

2011 | ISBN: 1439827370 9781439827376 9781439827383 | 326 pages | PDF | 30.11 Mb

Designed for advanced undergraduate and beginning graduate courses, this book presents must-know information for success in interactive graphics. Assuming a minimal prerequisite understanding of vectors and matrices, it also provides sufficient mathematical background for game developers to combine their previous experience in graphics API and shader programming with the background theory of computer graphics.

Well organized and logically presented, this book takes its organizational format from GPU programming and presents a variety of algorithms for programmable stages along with the knowledge required to configure hard-wired stages.
Easily accessible, it offers a wealth of elaborate 3D visual presentations and includes additional theoretical and technical details in separate shaded boxes and optional sections.
Maintaining API neutrality throughout to maximize applicability, the book gives sample programs to assist in understanding.
