Full Description
The articles in this text provide specific techniques for well-defined problems facing graphics programmers in the production of a variety of projects, including visual effects, real-time graphics and games. Each article provides a ready-to-use solution. The emphasis throughout the book is on the emerging graphics technology tht has been enabled by increases in hardware capabilities and computational speed, as well as advances in algorithms and programming techniques. The companion CD-ROM includes all the source code and images from the book.
