Deformation method based on deformable model with non-linear finite element

Abstract

The deformation of 3D models is one of the hot issues of computer graphics and other cross-discipline research.In view of the artificially using the linear strain on the model deformation,the authors proposed an effective model deformation approach.First,the original model was simplified through geometric delete method and the simplified models stayed as the form of the original model.Then,using the tetrahedron subdivision,the tetrahedral model was deformed by adopting the Green strain.Finally,the experimental results between linear strain and non-linear strain were presented in detail.The result also demonstrates that first simplifying the models then generating the tetrahedron,the simulation rate could be increased.
