Abstract
I presented two techniques for compression of 3D geometry that produce 2 to 3 times better compression ratios than standard geometry compression for real-time applications. I've shown several vertex caching algorithms for the efficient encoding of the geometry as generalized triangle meshes with a mesh buffer. This encoding allows most of the mesh vertices to be reused when forming new triangles. Second contribution allows various parts of a geometric model to be compressed with different precision depending on the level of details present. Together, the vertex caching algorithms and the variable compression method achieve compression ratios of 10 and 15 to one over binary encoded triangle strips. Our experimental results show a dramatically lowered memory bandwidth required for real-time applications.
