Edgebreaker 3D compression for triangle meshes



A first version of the Edgebreaker 3D compression software is freely available from
http://www.gvu.gatech.edu/~jarek/edgebreaker/eb/

Edgebreaker is a very simple state machine that encodes and decodes the connectivity of a triangle mesh as a sequence of symbols from the set {C,L,E,R,S} with a guaranteed cost of 1.8 bits per triangle and a practical cost of about 1 bit per triangle for meshes homeomorphic to a sphere and with a modest cost per handle and hole. The proposed code uses a parallelogram rule for predicting and compressing vertex location, but can be easily combined with other predictio schemes.

The current version of the software supports manifold meshes with an arbitrary number of handles but a single hole. Additional holes must be filled and then removed by the application.

Please let me know if you decide to use it. Thanks
