An Interactive Facial Animation System

In this paper an interactive facial animation system is described The system is built on top of the facial animation system developed by Keith Waters which uses a muscle based face model We built an interactive facial animation system on top of it to produce keyframe animations of a synthetic face model The user creates keyframes interactively by either giving prede ned universal expressions to the face or a meaningful combination of these expressions blended naturally on the face model or giving expressions to the face by moving the muscle vectors de ned on the face model The user might also change the orientation of the face for a keyframe by rotating it in x and y directions To create intermediate frames we use cosine interpolation
