CONTROL AND COORDINATION OF HEAD, EYES, AND FACIAL EXPRESSIONS OF VIRTUAL ACTORS IN VIRTUAL ENVIRONMENTS

This paper addresses the modeling and computational issues associated with the control and coordination of head, eyes, and facial expression s of virtual human actors. The emphasis, as much as possible, is on us ing accurate physics-based computations for motion computation. Some k ey issues discussed in this work include the use of kinematics and inv erse kinematics, trajectory planning, and the use of finite element me thods to model soft tissue deformations.
