Ah, that makes a lot of sense. I need to use a
vtkTransformPolyDataFilter and set the input of this filter to the
output of the vtkIterativeClosestPointTransform. Is this something
that can be chained together in paraview? Or do I need to make a VTK
filter that does all of this in one step and interface to the new
filter with Paraview?

Thanks,
