Don't see a solution for this (think its just the nature of

euler-angles)... anyone?

Tricky, definitely.

The only way to really do it is to record the previous euler result and using it to choose the proper solution.

It's pretty easy to do for a situation where you have that previous result, but when that result does not exist you're always going to get 2 valid solutions (at a minimum) and infinite solutions (cosine 0) at a maximum.

BTW, I think the code I posted is a more generic solution than what is there right now. I'd just have to go through it and test it out. It doesn't handle scale though.

cheers,

jon
