Longer version: with Pete Shirley releasing for free his three introductory mini-books on ray tracing this summer, then Matt Pharr releasing the book Physically Based Rendering for free, I asked Andrew Glassner if he could get the rights to release the classic An Introduction to Ray Tracing. He was game, clearing it with the authors, tracing down the right person at Elsevier to ask, going through the paperwork, and — freed!

One of the highlights of the conference is a series of half-day and full-day courses on a wide variety of topics in computer graphics.
In ray tracing was becoming a popular field of research. The course was a big hit, and we repeated it for a few years. This was before the Web, so the answer was to write a book.
We updated and revised our already terrific course notes, and produced this book. I was pleased and honored that this book brought together some of the finest people in the field — not just great researchers, but really good people.
The other contributors, in alphabetical order, included James Arvo, Robert L. Heckbert, and Pat Hanrahan. The cover was created by Jim Arvo. Jim realized that we used all of these shapes every day, but the Newell teapot is used just as much. A lot has happened since !

There are now many books on image synthesis, and even ray tracing in particular, and many of them are more modern and up-to-date than this.
But some people still like the friendly approach of this book, and the source code it offers for a fully working ray tracer. You can find new and used copies at all your favorite booksellers, including Amazon. Site map.
