From the backcover: "This intermediate-level book offers hands-on explanations that show you how to create dynamic moving objects. Each animation idea is explained, then the steps required to produce it are presented. Learn how to create belly-dancing logos, a disco full of gyrating dice, or a volcano that spews malted milk balls. Projects are based on the incredibly ray tracer Polyray, and examples cover every variable that defines a scene. You'll even find over 450MB of finished animations, the complete source code, which can be adapted for your own flics, and tools on the budled CD-ROM. Discover the concepts of scene creation and object coordination, vantage point control, lighting, textures, object interactions, surface deformations, and motions based on real physical laws... or make up your own rules. Animation How-To CD lets you plunge into your imagination."
