I only just found that rdna thread - I had completely forgotten about it. So I have not used the math from it yet.
Prior to my search (of just 20 minutes ago) I had been experimenting with a curvature sensor in nodes.
It is crude and wrong, but directionally correct. Here is a map of the curvature detected on my material test pawn. More curve = more white, less curve = more black.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
