Abstract

In computer animation, meshes corresponding to different objects may have to undergo similar deformations. Deformation transfer tries to mimic the deformation between given source mesh examples, onto given target meshes. In this paper, we propose a deformation transfer approach based on the Lie bodies representation of triangular meshes. The approach does not assume that the target and source meshes are of the same resolution or are registered. Due to the Lie bodies representation, the non-linearity in the space of transformations is accurately modeled which enables the framework to handle large deformations. Furthermore, under certain assumptions stated in the paper, the approach can also be used for the task of pose transfer.
