Locality Preserving Mesh Deformation Based on Mean-Value Skeleton Subspace

The skeleton subspace deformation(SSD) technique is a popular tool in many 3D applications.However,it is unsuitable for common user because of its complicated pre-operation,meanwhile the deformation maybe stretch or shrink unnaturally.A new improved deformation algorithm is introduced,it incorporates the SSD with the differential coordinates and mean-value skeleton coordinates,so that the local geometric detail and the skeleton characteristic are preserved.The main computation involved in the algorithm is a solution of a linear energy minimization problem,so it is real-time interactive.The experiment demonstrates that the algorithm produces vision plausible deformation in real-time,and it is well suited for various deformation application operated by common user.
