[vtkusers] Accessing vtkPolyData scalars with Python

[Berkowitz, Benjamin M]

Jothy, I get an attribute error when I try that...and I don't see GetInput() on the vtkPolyData() documentation.  If GetPointCells() is a subclass of vtkPolyData (and distanceMapper.Surface is a vtkPolyData), shouldn't I just be able to run it as a subclass without specifying an input?

If surface is your input then you should use

mapper.GetInput().GetPointCells()
