Here's my nightly snapshot. No new functionality today, just some refactoring and cleaning up. I haven't managed to get my normal computation any faster, but I like the look of the code now. If bagginsbill is the fastest programmer on the planet, I'm probably the slowest. :laugh: It occurred to me that I better do some proper testing now: compute the normals the hard way and see if they match. I did look at the normals for a cube as a quick test, but the symmetry might actually hide consistent mistakes quite well.

Only one more thing to do for the geometry export at this stage (I hope): unfortunately, the UnimeshInfo() call does not produce world coordinates for the unified figure mesh. That means we still have to grab the coordinates from the individual actors (a.k.a. "some assembly required"). We do get the topology, though (at least that is my understanding) and the mapping from each actor onto the mesh, so that should be easy as pie.
