Texture Mapping and Synthesis
|
| We present a novel constrained texture mapping method based on the harmonic map. Our method firstly parameterizes the surface of a 3D model on a planar domain by an angle-based-flattening technique; then specifies interactively the constraints between the selected feature points on the 3D model and the corresponding pixels on the texture image and determines the texture coordinates based on harmonic mapping between the embedding of the model and the texture image; lastly conducts adaptive local mapping refinement to improve the rendering result in real-time. Compared with other interactive methods, our method provides an analytically accurate solution to the problem, and the energy minimization characteristic of the harmonic map reduces the potential distortion that may yield in the constrained texture mapping. Experiment data demonstrate satisfactory rendering effects generated by the presented algorithm. |

| 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. |
