A deformation technique is a method to deform any part of, or an entire object, into a desired shape. Existing deformation methods take a lot of computational cost to represent smoothness correctly due to the constraints caused by differential coefficients of high degree. Thus, it is very difficult to find a general solution. In this paper we propose a LSM (layered subdivision method) that integrates a controlling mechanism, surface deformation, and mesh refinement processing 3D modeling and free-form deformable object matching. The proposed method is considerably more efficient and robust when compared to the existing method of free-form surface, because of the computation of the reference points of deformation edge using geometry of free-form surface. This approach can be applied to automatic inspection of NURBS models and object recognition.
