1. A method for encoding a representation of a three dimensional scene, comprising the steps of:

  • generating surface data representing polygonal surfaces, the polygonal surfaces comprising a plurality of elements;

    generating first data representing a first operation with respect to elements of said polygonal surfaces;

    generating second data representing a second operation with respect to elements of the polygonal surfaces, wherein the second operation is different from the first operation, and wherein the first and second operations are performed in a predetermined sequence with respect to elements of the polygonal surfaces to generate a representation of a three dimensional scene; and

    performing the first and second operations in a predetermined sequence on the surface data with respect to elements of said polygonal surfaces to generate a representation of a three dimensional scene.
