Deformation of 3D model in character animation is one of the important research fields in computer graphics. For the deformation of 3D models, a method using convergence calculation to generate desired shape is often employed. However, if shape is complex, convergence calculation would be very time-consuming. In general, it is genrally difficult to create rough and approximate control mesh that can realize the deformation efficiently with numerical stabilities. When a control mesh is too rough, the deformed shape would be very unnatural. When the control mesh was too fine, the computational cost increases. In this paper, we propose a fast and natural deformation method for creating character animation by changing control mesh by using the idea of level of detail technique.
