skeleton may be updated in a number of ways such as changing the joint angles
at different keyframes, which can be interpolated over time.
the skeleton is repositioned, the mesh must then be updated.
mesh vertices are considered as the “skin” around the bones forming the
skeleton. The mesh is deformed smoothly
as the skeleton moves.
is also known as skeletal subspace deformation

)Vertices are associated with
bones. Near joints, the vertices are
associated with multiple bones coming into the joint.
