3–D Human Modeling and Animation
Third Edition
All the tools and techniques you need to bring human figures to 3–D life
Thanks to today′s remarkable technology, artists can create and animate realistic, three–dimensional human figures that were not possible just a few years ago. This easy–to–follow book guides you through all the necessary steps to adapt your own artistic skill in figure drawing, painting, and sculpture to this exciting digital canvas.
3–D Human Modeling and Animation, Third Edition starts you off with simple modeling, then prepares you for more advanced techniques for creating human characters. After a brief overview of human anatomy, you′ll delve into the basic principles of proportion and structure, along with the different body parts. Exploring human modeling, texturing, rigging, and lighting leads you to more advanced techniques for digital figure animation.
Filled with?detailed, practical information about creating and animating 3–D human models, this updated Third Edition now features more than 500 full–color images that detail, step by step, the modeling and animation processes for both male and female figures. Most helpful of all, the included DVD features QuickTime tutorials tied to the modeling chapters and provides detailed color images from the chapters so you can get a quick start in bringing your visions to fruition!
