Mesh deformation and generation to realize the graphics display of cut tooth in haptic display system

It is introduced the graphics display of cut tooth by mesh deformation and generation in the virtual environment of haptic display system. In virtual environment the tooth and the tool are constructed by triangle-mesh. When operator use tool to cut the tooth, the vertices of tooth mesh which are surrounded by the tool will move to the surface of the tool, and all strait triangles generated in the course of mesh deformation will be fractionized to two or three triangles. By deforming and fractionizing the mesh of tooth, the graphics display of the course of tooth-cutting will be realized factually with no delay.
