I would tweak it by hand to figure out what it should be, is that the very first pixel?or the last?
If first, you can modify map[0] and see what to tweak it to, and then we could modify the mapping. Same with last (whatever number that is? 511?).
You can do that in javascript, just use:
Px = map[0][0] + whatever
Py = map[0][1] + whatever
Pz = map[0][2] - whatever
map[0] = [Px,Py,Pz]
I think that’s correct, didn’t test it, off the top of my head.
Also Jeff’s Hack for the mapper spinning might be useful until we get something like custom spinning of the model.
