[vtkusers] How to smooth a vtkPolyData Object?

If you've got the pure object you don't need GetOutput.
You only need GetOutput if the pdata comes from a function you've uses 
before
i.e.
vtkPolyDataReader* reader = vtkPolyDataReader::New();
reader->SetSomeKindOfPath("myString");
vtkSmoothPolyDataFilter* smooth = vtkSmoothPolyDataFilter::New();
smooth->SetInput(reader->GetOutput());

Otherwise it goes like this:
vtkSmoothPolyDataFilter* smooth = vtkSmoothPolyDataFilter::New();
smooth->SetInput(myPolyDataObject);

bye
