Currently, there are lots of changes while a final format settles out. In particular, r51 breaks compatibility with previously meshes, so for now I recommend r50 as the last stable revision.

Live demos:

• A Hand (small)
• "Ben" (medium, also see compression stats)
• Walt (large, does fast client-side normal reconstruction]
• Happy Buddha (1 million triangles, commentary)

This library includes:

• a simple Wavefront .OBJ file parser,
• a simple vertex cache optimizer and analyzer,
• a UTF-8 based binary encoder,
• no external dependencies except for C/C++ standard libraries.
