Subject: [ODE] Lo/Hi Stops for ball-sockets?
Hi :)
I've played with the hinge-joint recently and figured out how to use =
lo and hi stops to limit rotations.
My problem now is to have a similar system for ball-socket joints. The =
idea is to have limited range of motions similar to (for example) the =
joint holding arm and shoulder together. It should have some degree of =
mobility to rotate around an arbitrary axis of motion, and it should be =
able to deviate from the initial axis of rotation to some degree.
Essentially it should be able to move inside a cone-of-freedom (plus =
it is only allowed to twist to a certain extend).
Help please.
Henri
