Abstract
Wavemesh is a powerful scheme for 3D triangular mesh processing. In sharp contrast with other approaches using wavelets for mesh compression which apply only to meshes having subdivision connectivity, wavemesh can simplify, approximate, and compress meshes even if they do not respect this constraint. Results clearly indicate that wavemesh outperforms the other approaches in terms of progressive lossless compression. We propose in this paper an improvement for our scheme : higher efficiency for meshes with large subdivision connectivity sets, as shown by experimental results. Also, in some cases, the enhanced wavemesh can even perform better than monoresolution approaches in terms of connectivity compression.
