1. A method of encoding and decoding a dynamic mesh having a temporal sequence of mesh models, comprising:

  • encoding and decoding a first mesh model in the temporal sequence of the dynamic mesh, by encoding and decoding the geometry of a set of mesh node points in the first mesh model; and

    encoding and decoding subsequent mesh models in the temporal sequence of the dynamic mesh, by encoding and decoding the deformable motion of each mesh model, represented by a mesh node motion vector for each node point.
