An Introduction to Ray Tracing (The Morgan Kaufmann Series in Computer Graphics)
"Glassner's excellent book is indispensable for anyone wishing to understand and implement the up-to-date methods of ray tracing (and in the process, learn about surface physics too)...It is well edited and avoids any of the repetitions or contradictions that might have arisen in a multi-author text. Covering both theory and practicalities it includes sufficient detail (and code) to allow competent programmers to set up their own ray tracing systems...To me it seems to be an exemplary text and I highly recommend it."--John Lansdown, THE COMPUTER BULLETIN"Excellent reference for ray tracing for both the beginner and the experienced ray tracer. It is the only book we know of completely dedicated to ray tracing."--IMAGING & VISION COMPUTING
