A first television system based on the Autosophy information theory is now being tested. The new television marks a major theoretical break from conventional television based on t...
We present a new geometry compression algorithm for manifold 3D meshes based on octree coding. For a given mesh, regular volume grids are built with an adaptive octree. For each gr...
