Abstract
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 to faithfully recover the original connectivity. By separating the connectivity from model geometry and properties, the method avoids encoding vertices (and properties bound to vertices) multiple times. This provides a reduction in the size of the bit-stream compared with encoding the model as a manifold.
