1. A method of encoding an update of a polygon mesh having at least one target vertex, comprising:
defining a local index of a vertex that neighbors the target vertex, the local index defining a position of the vertex relative to the target vertex; and
encoding the mesh using the local index, the encoding comprising
storing the local index of the vertex; and
storing a global index of the target vertex, the global index defining the position of the vertex relative to a pre-defined array.
