Abstract: To promote the efficient reuse of existing animation resources,an approach for transferring 3D animation from a source mesh to a target mesh based on mean value coordinates is proposed.It first builds a constrained mapping between the source and the target meshes with a small set of markers,then deforms the target mesh adhering to the deformations of the source mesh by means of mean value coordinates.We make significant improvements over previous approaches,in particular,our approach no longer requires the source and target meshes to have the same topology and can transfer the deformation both efficiently and faithfully.
