A New Constrained Texture Mapping Method

摘要

The validity of texture mapping is an important issue for point or mesh based surfaces. This paper provides a new constrained texture mapping method which is capable of ensuring the validity of texture mapping. The method employs the "divided-and-ruled" strategy to construct a direct correspondence between the respective patches of the texture image and 3D mesh model with feature matching. The mesh model is segmented based on the "approximate shortest path". Further, a "virtual image" relaxation scheme is performed to refine the rendering effect. We show how mesh morphing can be conducted efficiently with our constrained texture mapping method. Experiment results demonstrate the satisfactory effects for both texture mapping and mesh morphing.
