1. A system for embedding information in a three-dimensional geometric model comprising:

  • a) means for preparing a three-dimensional geometric model wherein said three-dimensional geometric model comprises a plurality of primitives, and b) means for embedding said information in said three-dimensional geometric model by changing a geometric parameter of said three-dimensional geometric model wherein said means for embedding includes;

    i) means for searching a start primitive for ordering primitives, ii) means for ordering sets of primitives in the plurality, and iii means for selecting a primitive in the sets in accordance with said order and changing the geometric parameter of the selected primitive correspondingly to said information.
