Geometric Compression 

Overview

The size of geometric models in Computer Graphics is ever increasing and increasing faster than the processing power of commodity graphics cards. Some current models consist of millions or billions of triangle primitives. This is problematic if such models need to be stored or transmitted. On solution is to losslessly compress the geometry (point positions) and connectivity (linking of points into triangles) of models. Unlike previous approaches we separate rather than interleave the two processes.
