Claim One:
1. A method for animating artwork based on handle movement on the artwork, the method comprising: generating, by a processor of a computing device, a mesh based on the artwork, wherein the mesh comprises triangles with vertices on the artwork, wherein bounded biharmonic weights for handles represent significance of individual handles to individual vertices of the mesh; receiving, by the processor of the computing device, a movement of a handle of the handles; based on the movement, minimizing, by the processor of the computing device, a closed-form expression to find handle affine transformations that provide a deformation of the artwork with minimal stretching, shearing, and skewing in local areas; and animating, by the processor of the computing device, the artwork by transforming the vertices of the mesh according to the determined handle affine transformations and the bounded biharmonic weights, wherein the local areas are represented as rotation clusters comprising groupings of vertices, and wherein minimizing the closed-form expression comprises minimizing an energy function to minimize differences between one set of points representing a rotation cluster transformed according to a deformation of the mesh and another set of points representing a simple rotation of the rotation cluster with no stretching, shearing, or skewing.
