[vtkusers] VTK and molecules

[Eric Germaneau]

Hello,

I'm a nwe pyvtk user and I've found this example 
<http://public.kitware.com/pipermail/vtkusers/2006-August/086395.html> 
code to display atoms with vtk but I get the following error:

/Traceback (most recent call last):
  File "vtkex.py", line 127, in <module>
    actorCreator.AddBonds(sample_atoms, sample_bonds)
  File "vtkex.py", line 38, in AddBonds
    self.polyData.SetPoints(atomPts)
ValueError: method requires a VTK object

/Does someone can tell why it doesn't work?
I'm looking for more examples  ....
Thanks in advance,

Regards,

                     eric.
