This invention relates to a method and apparatus for animating a synthetic body part, more particularly to a 3D-animation system and method utilizing a database of basic postures. In a first step, for each frame, a linear combination of the basic postures from a database of basic postures is obtained by minimizing the Euclidean distance between the displacement of critical points. The displacement information is supplied externally, and typically can be obtained by observing the displacement of physical markers placed on a moving physical body part in the real world. For instance, the synthetic body part may be an expression of a human face and the displacement data is obtained by observing physical markers placed on the face of an actor. The linear combination of the postures in the database of postures is then used to construct the desired posture. Postures are constructed for each time frame and are then display consecutively to provide animation. The invention also provides a computer readable storage medium containing a program element to direct a processor of a computer to implement the animation process.
