An Introduction to Ray TracingThe creation of ever more realistic 3D images is central to the development of computer graphics. The ray tracing technique has become one of the most popular and powerful means by which photorealistic images can now be created. The simplicity, elegance and ease of implementation makes ray tracing an essential part of understanding and exploiting stateoftheart computer graphics. An Introduction to Ray Tracing develops from fundamental principles to advanced applications, providing "howto" procedures as well as a detailed understanding of the scientific foundations of ray tracing. It is also richly illustrated with fourcolor and blackandwhite plates. This is a book which will be welcomed by all concerned with modern computer graphics, image processing, and computeraided design.
