《Mathematics for 3d game programming and computer graphics》
http://www.mathfor3dgameprogramming.com/BOOK DESCRIPTIONThis updated third edition illustrates the mathematical concepts that a game developer needs to develop 3D computer graphics and game engines at the professional level. It starts at a fairly basic level in areas such as vector geometry and linear algebra, and then progresses to more advanced topics in 3D programming such as illumination and visibility determination. Particular attention is given to derivations of key results, ensuring that the reader is not forced to endure gaps in the theory. The book assumes a working knowledge of trigonometry and calculus, but also includes sections that review the important tools used from these disciplines, such as trigonometric identities, differential equations, and Taylor series.ABOUT THE AUTHOREric Lengyel is a veteran of the computer games industry with over 18 years of experience writing game engines. He has a PhD in Computer Science from the University of California at Davis and an MS in Mathematics from Virginia Tech. Eric is the founder of Terathon Software, where he is currently working on a Halloweeen-themed game called The 31st.TABLE OF CONTENTS
