The input source follows the driver surface in the manner that
the driver surface changes to the deformed surface.
The Input Surface is subject to a wrap.
It is internally bound to the reference Driver Surface
and animated to follow the reference to extent that the reference
would need to move to reach the Deformed Surface.
The Driver Surface and Deformed Surface
should be composed of triangular polygons with normals and the two
inputs are are expected to match topology.
The Input Surface can be anything containing points.
Only points are affected to create the Output Surface.
