This is the fourth edition in this series of books on advanced graphics.
This book is a collection of forty-three articles around the common theme of shading images in real time. Many of these effects have been common in the movie world for many years, but in that application the shading can be done on very expensive machines and the time it takes to produce an image is not important because the resulting image is to be shown on screen rather than immediately on a display. Now, with the increasing power in the PC's in widespread use, these techniques are being brought down to the standard desktop.
In this book a wide selection of authors discuss the start of the art in shading. They are, for the most part, active professionally in the graphics display business. A number of them work for video card companies, a number work for gaming companies, or for companies producing software used in gaming. Many are involved with the computer science departments of universities around the world where the most advanced image programming is being researched.
This approach provides for a fast time to print, rather than one author taking a year to write the book. In this industry a year is a lifetime, well, at least a generation in the software.
