Real-time rendering

Amazon.com Review
One would think that the title of Tomas Moller's and Eric Haines's book, Real-Time Rendering, would be a contradiction in terms. How can such a computationally intensive process as rendering computer graphics ever hope to be done on the fly, in the blink of an eye, without delay--in short, in real time?
The term rendering, as it applies to computer graphics, refers to the mathematically intensive process of creating a picture or sequence of frames based on geometry. The duration of this process is dependent on the complexity of the scene (a forest with many trees and thousands of leaves will take much longer to render than a scene consisting of a white box over a gray background) and the speed of the hardware doing the calculations.
When Pixar's Toy Story was first released, the computer animation community was all abuzz with how it was done, and someone at Pixar mentioned that over 100 SGI workstations were used for rendering the frames over the course of almost two years. Someone else extrapolated this data and figured out that the same movie could have been rendered on one contemporary PC over the course of about 80 years.
The authors deftly answer the question, not only asserting that it can be done, but since this book is a programmer's guide, they list snippets of programming algorithms that help outline how it can be done.
Because the software and hardware is constantly and rapidly evolving due to the insatiable need for more realistic and complex graphics, the book avoids getting too specific. To quote the authors, "The field is rapidly evolving, and so it is a moving target." This lack of specificity doesn't detract from the usefulness of the book, though. Instead, it works at a higher, more abstract level, describing approaches to rendering techniques using generic algorithms. It is up to the programmer to apply these methods to the specific program or system on which it is to be implemented.
Real-Time Rendering describes some very complex methods, and this book is not for the average computer graphics creator. However, if you are working in an industry that depends on real-time rendered animation--like the gaming, medical, or military fields--or you are building the next-generation real-time render engine, this book will offer insight and concepts you can use to build some impressive software. --Mike Caputo --This text refers to an alternate Hardcover edition.
Review
Real-Time Rendering has been a required reference for professional graphics practitioners for nearly a decade. This latest edition is as relevant as ever, covering topics from essential mathematical foundations to advanced techniques used by today's cutting edge games. --Gabe Newell, President, Valve
Real-Time Rendering provides a solid introduction to the essential techniques every graphics programmer should know. It also serves as a great reference for finding relevant publications and is a joy to read. --Martin Mittring, Lead Graphics Programmer, Crytek
One of my favorite graphics books is Real-Time Rendering. . . . If you only get one graphics book, get this one. --Ron Fosner, author of Real-Time Shader Programming
