A multiresolution wavelet scheme for irregularly subdivided 3D triangular mesh

Abstract

We propose a new subdivision scheme derived from the Lounsbery’s 1:4 face split, allowing multiresolution analysis of irregularly subdivided triangular meshes by the wavelet transforms. Some experimental results on real medical meshes prove the efficiency of this approach in multiresolution schemes. In addition we show the effectiveness of the proposed algorithm for lossless compression.
