FACIAL ANIMATION METHOD

摘要

A three-dimensional displayed head consisting of a set of meshes is animated by modelized facial muscles. For natural animation of the lips in speech, the lower and upper lips are differentiated in a set of lip mesh based on the vertices of the mesh on a boundary of the labial angle and the mouth opening, and the lower and upper zones of the head are divided by the boundary. Modelized muscles (M2, M3G, M4G) attached to the upper lip, with effect areas secant in the upper zone, and (M6G, M7G, M8) attached to the lower lip, with effect areas secant in the lower zone, displace the vertices of the mesh respectively in the upper lip and under the nose and in the lower lip and the chin. Other muscles (M4G, M5G, M6G, M9) have effect areas in the lower and upper zones.
