View Full Version : Realistic Ribs

What are some techniques (they don't have to be maya specific) for building ribcages. I can find very little material on realistic rib setup.

There needs to be a certain amount of expansion and contraction in bends of the spine. Cages need the option to stretch though when animation becomes exaggerated. Cages need to breath. Cages need ribs that don't collide when you bend over and twist at the same time (this is the hardest I find).

Does anyone know of any functional radial limitting fields as a plug in or something for Maya? Basically constraining a joint or something to exist only within a specified range/radius?

Something that like, say would not allow a joint to move to within 5 or fewer units of a provided center point, and not outside of say, 10 units from that same point, with a soft fall off on either side to try and keep it in the middle of those. Anyone?

This would provide for one of the best rib cage controls that I can imagine, much better than simply using a clavicle pivot point and having to rotate the scapula as well.

It's a hack, but maybe you could rig something with the translate limits in the transform node? You'd have to do some sort of weird node network, but I could see you getting distance from something else's transform, then limiting the XYZ based off of that... maybe not...
