  This paper presents a new progressive compression method for triangular
meshes. This method, in fact, is based on a schema of irregular
multi-resolution analysis and is centered on the optimization of the
rate-distortion trade-off. The quantization precision is adapted to each vertex
during the encoding / decoding process to optimize the rate-distortion
compromise. The Optimization of the treated mesh geometry improves the
approximation quality and the compression ratio at each level of resolution.
The experimental results show that the proposed algorithm gives competitive
results compared to the previous works dealing with the rate-distortion
compromise.
