[vtkusers] How to smooth a vtkPolyData Object?

[Ming Chao]

Hi Luca and Fritz,

Thanks for pointing out the input to smooth->SetInput(). I just tried to
input the polydata object directly to the smoother, but I got an error from
the vtkOutputWindow:

C:\VTK\VTK\Common\vtkObject.cxx, line 131
vtkObject: Destructing!

Then the program stopped running. Could anybody spot what is going wrong?

Thanks,
Ming
