Claim One:
1. A method for deformation transfer of a source three-dimensional (3D) geometry to a target 3D geometry for computer-implemented blendshapes animation, the method comprising: assigning a virtual triangular mesh having a plurality of virtual triangles to a prescribed region of an animated figure that are presented by a computer-generated mesh; and solving a linear system equation by a computer to generate a mesh that represents a deformed state of the animated figure, said linear system equation being expressed by: [ A α A v ] X ′ = [ F α F v ] , where X′ is unknown vertex positions of a deformed mesh, F is deformation gradient of a nondeformed state, and A is a matrix that represents deformation gradient when multiplied by the vertex positions of the deformed mesh, and where A v is a deformation gradient matrix of the virtual triangles of the deformed state, F v is a deformation gradient of the virtual triangles of the nondeformed state, and α is a prescribed weight.
