We investigate a recent mesh subdivision scheme, allowing multiresolution analysis of irregular triangular meshes by the wavelet transforms. We consider the wavelet scheme construction in terms of an inverse problem. Some experimental results on different meshes prove the efficiency of this approach in multiresolution schemes. In addition we show the effectiveness of the proposed algorithm for lossless compression.
