This node defines all components of a joint animated, skin deformation model. It ties the geometry to the rigging and animation.The skin is surface of the model. It is smoothly deformed as the model is animated throughout the animation cycle. Each joint specifies which vertices of model are affected by joint motion and how much that motion effects that vertex. This allows a joint to change the position of verticies not immediately adjacent to the joint.

mesh must be a single mesh with user-supplied vertex coordinates. The vertex coordinate array must be available to all children of this node, specificatlly to all of the children of joint.
