This is not a book of algorithms on computer graphics methods. Instead, it is a comprehensive high-level survey of rendering techniques for making the graphics appear to occur in real time. This book has a very academic tone to it, and with the exception of chapter 3 which is on matrix transforms, it has precious few implementation details. Some reviewers have called it a successor to Foley and Van Dam's classic text, but I find this misleading. That book is primarily about computer graphics techniques, and is not that concerned with real-time issues. The bibliography of this book is extensive and impressive, and if you are doing research on the subject it is probably essential, especially if you are interested in the subject of virtual reality where real-time presentation is a must. However, if you are just looking for pseudocode or more "cool effects" to insert into a game or graphics program you are writing/programming you would do best to look elsewhere.
