Zusammenfassung:A scalable three-dimensional (3D) mesh encoding method includes dividing the 3D mesh into layers of complexity into a plurality of graduated levels and generating vertex position information and connectivity information of each of the plurality of levels. The vertex position information about the 3D mesh is encoded based on a weighting in each bit plane and vertex position information having a higher weighting in each bit plane is first encoded.
