[Paraview] Programmable filter: Use of VTK filter classes

[John Fraser]

Hello,
 
I'm using Paraview on 4.0.1.  I was under the impression that it would be possible to use some of the many VTK filters from a Python programmable filter, however I seem to only be able to instansiate some of the filters, for others I get the message:
 
Traceback (most recent call last): 
File "<string>", line 21, in <module>
File "<string>", line 4, in RequestData
AttributeError: 'module' object has no attribute 'vtkSelectEnclosedPoints'
 
from the following line of code:
 
v = vtk.vtkSelectEnclosedPoints()
 
Is it possible to use something like vtkSelectEnclosedPoints from a programmable filter?
 
Thanks,
John
