ABSTRACT:
A method for compressing a mesh having a plurality of vertices, each vertex characterized by a degree equal to the number of edges incident thereon, including arranging substantially all of the vertices in a consecutive order, generating a topology list including the degrees of the vertices in the consecutive order, and providing a coded stream of signals including the topology list.
