Logistics What is this course about? � Textbooks � Computer Animation: Algorithms and Techniques by Parent � Physics for Game Developers by Bourg � Selected papers from CG literature � Supplement lectures � Not necessary, but nice to have as references. Remember this from CGII? Definition of animation an·i·ma·tion (n) real photo Photographic Photography: camera scene processing print a motion picture made from a series of drawings simulating motion by means of processing slight progressive changes in the drawings Computer 3D camera tone synthetic Graphics: models model reproduction image Animation deals with making this move Early Animation Early Animation � Movie Records � The Zoetrope QuickTime™ and a Sorenson Video decompressor are needed to see this picture.
