[vtkusers] ICP on Image?

[Matthew Seier]

Hey All,

I have implemented an Iterative Closest Point Transform on a 2 sets of 
PolyData (2 isosurfaces) but am having difficulty applying that same 
transform to a set of VTK ImageData.  I would like to take the transform 
that is generated by the ICP, and apply it to a set of vtkImage Data.  The 
documentation says TransformPolyDataFilter must be used, but I don't think 
that will work, as I want to apply the transform to ImageData.  I having 
been experimenting with different ways, but I keep getting "Empty or Null 
Source" error messages from the ICP.  Does anyone know how to apply an ICP 
transform to a set of Image Data?

Thanks,
Matt
