Techniques of compressing level of detail (LOD) data involve generating a codec that can perform progressive refinement on a single rate decoded LOD. Nevertheless, by generating a small amount of extra information in a single rate decoded LOD, a progressive refiner can use the information provided in the single rate decoded LOD to refine the LOD. For example, in some implementations, the extra information is a corner of a face of a mesh; the progressive decoder may then begin traversal of the mesh from that corner for refinement. It is noted that the single rate decoded LODs are able to be refined by the same refinement information as the progressively decoded LODs.
