Ray Tracing for the Macintosh/CD

Paperback book, Published 1994, by Waite Group Press (out of print)

(Copies of this book sometimes show up at discount book centers, and you may still be able to find it on-line... Click book cover above to search for it on Amazon.)

My (now out-of-print) tutorial book "Ray Tracing for the Macintosh CD" shows you how to create your own photo-realistic computer images, with free software for Mac, Windows, Linux, etc. The book comes with a Mac OS (9) CD-ROM that has the full POV-Ray Macintosh application & documentation, lots of scenes with sources from professional artists, animated QuickTime movies, an on-line multimedia encyclopedia of POV-Ray keywords, many Mac utility programs, etc. The book starts at an introductory level, giving an overview of ray tracing and 3-D art. It then explains POV-Ray, its language, and starts you building scenes. It has a chapter on advanced scene design and creation. There is a chapter on creating QuickTime animations, with tips on how to move things around in your scene. There are many example movies on the CD-ROM, and tools to create QuickTime movies yourself. This book covers POV-Ray Mac OS version 2.2, but the techniques and examples in the book carry over to POV-Ray version 3, as well as other rendering applications.
