Compression Joints in NTRT

[51stpage]

I was wondering if there's a way to do end to end compression joints using two rods in NTRT? I think I have a way to fake it by using a complicated multi-rod, multi-string approach similar to this spine but would prefer not to include the added complixity in the model if I can help it. If not, I'll use the more complicated way.

can you explain what you mean by an end-to-end compression joint? do you mean that you want to put a rotary joint between two rods? Or something else? vytas

Sure. I'm looking to model human hand-like structures so I'll have bones butting up against each other then rotating around an axis. I've found references to 'rotation:' in the documentation though I haven't had a chance to explore how those exactly work.

If there's a way to do hinge and ball-joints that would be great. As a side-query, is there a way to add arbitrary shaped objects in the world for the model to interact with? I've seen what look like static ground features but was wondering about spheres and cylinders.

Thanks for getting back to me.
