Wavelet-based Multi-resolution Analysis of Irregular Surface Meshes

Lounsbery has brought out a multi-resolution analysis scheme for triangle meshes, but it can only be applied to the regular triangle meshes, and includes a remeshing of the existing 3D data. In order to settle the problem, based on the wavelet, it extends Lounsbery’s scheme. Based on the algorithm, it can directly compress the irregular meshes, and then obtain multi-resolution meshes. In the process, based on the connectivity of the processed meshes, it can also optimize the triangle meshes, make them more regular, and then improve the algorithm. Comparing with previous algorithm, the results prove that the proposed algorithm has good speed, efficiency and practical values.
