US Patent 9202300 Smooth facial blendshapes transfer

A method for deformation transfer of a source three-dimensional (3D) geometry to a target 3D geometry for computer-implemented blendshapes animation includes solving a linear system equation in which blendshapes deformation transfer with a virtual triangular mesh is performed, where the virtual triangular mesh having a plurality of virtual triangles is assigned to a prescribed region of an animated figure that are presented by a computer-generated mesh, and/or in which blendshapes deformation transfer is performed with Laplacian smoothing.
