Object-Oriented Ray Tracing in C++: Nicholas Wilt: 9780471304142: Book: Computers & Technology: eCampus.com

Focuses on object-oriented methods to greatly enhance both the speed of processing and the quality of the resulting graphics. Includes a brief introduction to ray tracing as well as background on advanced topics. A ``User's Manual'' is also included for the ray tracing class library, with code examples for both basic and sophisticated ray tracing problems. Available on disk is a ray tracing library with source codes.
