Abstract :
An adaptive subdivision method is proposed in this work for automatic post-processing of a 3D graphic model of coarse resolution. The method is an improved version of the Modified Butterfly Scheme (MBS) developed by Zorin et al. The main contribution of this work is to exploit the local smoothness information of a surface for adaptive refinement of a coarse 3D graphic model. With this approach, we can avoid unnecessary subdivision in relative smooth legions. The new algorithm not only reduces the computational complexity but also reduces the storage space. It is demonstrated via experiments that a more visual-pleasing representation can be obtained
