In Computer Animation: Algorithms and Techniques, concepts and formulas used behind the scenes and under the hood of contemporary animation software are clearly explained for the programmer and technical director. Hardbound, illustrated freely, and with eight-page color gallery, there are six chapters and three appendices. It is important to note that this chapter is not about which buttons to push in one software package is given, but rather about the use and explanation of formulas for representing a particular simulation. Perhaps the best feature of this book is information and examples available on the companion web site. Rather than including a CD-ROM, which increases the cost of books and information that could grow stale, the reader can find sample animations and ready bits and use codes, and links to relevant Web sites. There are a number of books available on computer animation software packages, but precious little about how they do what they do:. Computer Animation Algorithms and Techniques is an invaluable resource, a textbook for anyone who is interested in animation or computer programming for anyone who just wants to get under the hood of their favorite animation application.
