Thanks Thomas,

I'm glad it's working well for you.
Please try to apply a null/identity transform where the starting points are the
same as the destination points.

I rendered a loop of triangles and they all wound up exactly where they were
supposed to, so I'm hopeful that this is all it will take.

I believe this is what is referred to as a "rigid body transform", as opposed to
an affine transform, which may apply things like scaling or shear.
So I think I just need the ordered triple, which gives us a triangle with a face
normal, and that's all that's necessary and sufficient to completely describe
the orientation.

I'm sure TOK probably coded something like 15 years ago ;)
