Principles of Three-Dimensional Computer Animation -- now the standard introduction to computer animation -- is in its third edition, greatly expanded and revised to reflect advances in animation technology. Covering a broad range of 3D modeling, rendering, and animation topics from the most basic terms and explanations to advanced techniques, without recourse to mathematical equations or programming code, this text allows both neophytes and sophisticated animators to improve their skills and understanding of the field. Outlining the general principles common to all 3D computer animation systems, Michael O'Rourke guides the reader through the necessary steps, from preproduction and design, through a variety of production techniques, to postproduction and editing. Beginning with modeling, rendering, and animation basics, chapters progress to advanced techniques and principles, including updated material on subdivision surfaces, compositing, pose-based animation, non-linear animation, paint-based modeling, advanced texturing, character animation, and facial animation. With hundreds of drawings, diagrams, and renderings, O'Rourke illustrates and clarifies every topic discussed. Any specific software package can be easily tackled with this information at hand. Animators, art directors, industrial and interior designers, students, and architects alike will find this text immensely readable and useful.
