Webabstract = "In this paper, we propose a new algorithm to code the animated three-dimensional (3-D) mesh model. After we classify the mesh frames in the animation model into intra- and inter-meshes, each mesh frame is decomposed into linear triangular strips, which in turn are partitioned into several fixed-length segments.
