[vtkusers] Point Cloud Registration using ICP

[John Durkin]

David,

Unfortunately my scenes overlap and one is not a complete subset of
the other.  I have the vtkIterativeClosestPointTransform up and
running, but as you guessed it's giving me unsatisfactory results.  Is
there a method to do this in VTK or should I try using some filters in
ITK?
