Locked Joint
A point cannot exceed the rotation around a point to a maxmium angle value, relative to the origin point zero.
Meaning if we have a point (origin), and another point (knee). The position of the knee may not lye outside a cone projected from the center of origin,
Rotating the origin will slide the position around the origin center Moving the knee will lock at the edges of the projected cone.
distance is handled by another element, and is optional here.
This demo uses two constraints together:
cone()limits the angle of the child around its parent.track()keeps the child at a fixed distance from its parent.
So the cone decides where the point may rotate, while track decides how far away it stays. Combining them gives a simple joint with angular limits.
