A system for compressing 3D meshes that maintains and exploits vertex cache optimal ordering of triangles.
Vertex Cache Optimised Mesh Compression
This is a proof of concept library expanding on previously presented index buffer compression mechanisms and adding compression for vertices as well.
Basically, it expands on the index buffer compression using a parallelogram predictor and a kind of universal code (related to exponential golomb) along with an exponential moving average to give fast adaptive compression for vertex attributes. A more complete version of this is outlined in this blog post.
