Morphing 3D Mesh Models Based on Spherical Parameterization

Based on spherical parameterization, we in this paper present an algorithm to naturally morph a mesh model to another. Our algorithm first adjusts poses of both the models to align them in 3D space. Then, the two normalized models are parameterized onto a common spherical parametrical domain. Subsequently, the algorithm matches a group of given features of the models on spherical domain via a re-parameterizing procedure. As a result, the correspondence of two models´ vertices are obtained. Finally, our algorithm interpolates original coordinates of the source model to their corresponding coordinates on the target model to create morphing.
