very impressive maths behind all this.. clever stuff.
The only thing that concerns me about this tool is the sheer expanse of the expression it's calculating per frame... its huge. I'm certain you could rewrite this tool using a utility network that would increase the performance drastically, but also maybe open up attributes of the system that could be interactivley changed by the animator / user ?
well done though...
Wow dude, I just went to the Maya MasterClasses this year and sat in on ILM speakers that were talking about just this concept. Thier approach was a plugin but this seems to work. The only thing they have on you is that the constraint is a parent one and not a seperate point and orient. If you could get that you'll make some ILM TD's look like amatuers.
It's going to take me a bit to figure out how you did this.
Really nice work.
