A method for encoding a non-manifold polygonal mesh operates by converting an original (non-manifold) model to a manifold model, encoding the manifold model using a mesh compression technique, and clustering, or stitching together during a decompression process, vertices that were duplicated earlier...http://www.google.fr/patents/US6452596?utm_source=gb-gplus-shareBrevet US6452596 - Methods and apparatus for the efficient compression of non-manifold polygonal meshes
