[vtkusers] Convert vtkPolyData to vtkPoints

[Bayliss, Chris (Chicago)]

Hi,

 

Does anyone know how to convert vtkPolyData to vtkPoints?  I am having
trouble figuring out how to deal with converting different data types in
general, is there a good explanation of how to do this somewhere?

 

I am trying to import a list of vtkPolyData points in order to use them
in vtkThinPlateSplineTransform.  The point data file is below.  

 

 

Points data file:

 

# vtk DataFile Version 3.0
