Realistic Volume Animation With Alias

Computer generated animation is widespread in lms, television commercials , multimedia and games. The availability of powerful modeling and animation packages has contributed greatly to this popularity and has been instrumental in bringing computer animation into the mainstream. These packages work primarily with polygonal representations of models. Deformation for animation is achieved by means of user deened skeletons. In this paper, we describe a method which uses a volumetric thinning algorithm to automatically build a skeleton from a volume model. This volumetric skeleton is then used with an oo-the-shelf animation tool to achieve smooth and realistic volume animation. Animation techniques like key-framing and inverse kinematics can thus be directly used in the volume domain.
