A SOFA plugin experimenting plasticity defined by a constraint
The version presented here is minimal and only works for objects modeled using tetrahedrons, applies the same constraint to every element and only constrains the first stress element. The scene FingerStopper2 can be used as a demonstration of the effects of the constraint. It contains 2 fingers, one that is not constrained and stays in the neutral position once animated, and the other which can be moved with the cable and undergoes the plastic constraint
