The method captures a 3D model of a face, which includes a 3D mesh and a series of deformations of the mesh that define changes in position of the mesh over time (e.g., for each frame). The method also builds a texture map associated with each frame in an animation sequence. The method achieves significant...http://www.google.co.uk/patents/US6072496?utm_source=gb-gplus-sharePatent US6072496 - Method and system for capturing and representing 3D geometry, color and shading of facial expressions and other animated objects
