The RenderMan Companion : A Programmer's Guide to Realistic Computer Graphics

Rating:
Summary: Great, not just for RenderMan, but Computer Graphics too.
Review: This is an amazing book about an amazing product and specification. If you want to really learn what computer graphics is all about, you could do no better than read this book. RenderMan was written by the smartest people in the subject, and is the product of years of both insight and trial-and-error.

This book is clear, concise, and still extremely timely even 10 years later (a lifetime in CG). A new edition couldn't hurt though, encompassing some more recent change.
