Valence-Driven Connectivity Encoding for 3D Meshes
(Pierre Alliez and Mathieu Desbrun).

This page illustrates the connectivity encoding technique described in "Valence-Driven Connectivity Encoding for 3D Meshes". The application is an implementation of the paper. It opens wrl 97 files containing one 2-manifold triangle mesh, and allows the user to visualize the edge-centered conquest described in the paper. Several visual debugging options are available. Resulting bit-rates are given in bits per vertex. The executable has been compiled for a Win32 platform (Windows 9x/NT/2000) and uses the OpenGL library. Some animations are also available.
