[vtkusers] Accessing vtkPolyData scalars with Python

[Forrest Sheng Bao]

I used python-vtk a while ago. So I am trying to help you using my dim
memory.

What's the data type of distanceArray?  I think it should be a python List.
If that's the case, you don't need GetTuple.

If you simple need to access data in VTK files, you can use pyvtk, which is
simpler. http://code.google.com/p/pyvtk/

Cheers, Forrest
