Abstract
Photorealistic facial animation movies have been generated by using Metasequoia (a 3D modeler) and Maya (a 3DCG software). It is so hard to express the lively human expression so that each part of a face moves simultaneously, with the ordinal animation which expressed change between expressions by morphing. Thus, we employ the F.A.C.S that combine minimum units of facial expression movement (Action Unit) then express the details of human facial expression. We have created several pieces of facial animation based on the F.A.C.S.
