28 * A constraint between two rigid bodies, each with a pivot point. The pivot
29 * points are described in the body's local space. The constraint limits
30 * movement of the two rigid bodies in such a way that the pivot points match
31 * in global space. The spherical constraint can be seen as a "ball and
32 * socket" joint.
