描述

A body that forms part of a Physics articulation.

An articulation is a set of bodies arranged in a logical tree. The parent-child link in this tree reflects that the bodies have their relative motion constrained. Articulations are solved by a Featherstone solver that works in reduced coordinates - that is each body has relative coordinates to its parent but only along the unlocked degrees of freedom. This guarantees there is no unwanted stretch.
Like with regular Joints, there are two anchors for each pair of connected articulation bodies. One anchor is defined in the parent body's reference frame, whereas the other one is defined in the child's reference frame. Changing the constraints, you directly affect the allowed space for relative positions of the two anchors. For instance, ArticulationDofLock.LockedMotion will not allow any relative motion at all.
