[Paraview] ParaView python vs VTK python api (UNCLASSIFIED)

Hi Andy,

I think the filter option may not be viable as the VTK code is the part that 
creates the VTK data structure (points - vtk.vtkPoints(), triangles - 
vtk.vtkCellArray, polydata - vtk.vtkPolydata()) using VTK python api.

This is actually related to the catalyst question I asked. Luckily the user's 
code is in python already and Sean Ziegeler mentioned to bypass catalyst and 
just call ParaView using PV Python api (and run the simulation code python 
script using pvbath/pvpython). But the user's code is in VTK python and not 
ParaView python which caused some issue here.

In that regards, are there documentation that I can look up on the comparable 
Python API between VTK and ParaView?

Thanks
-simon

It may not be possible to do what you want explicitly. ParaView can be viewed 
in some ways a wrapper around VTK filters. You can try the programmable filter 
which uses the VTK Python API but is still intended to operate like a filter 
(i.e. not modifying the input data sets, etc.).

	Hello,

	I would like to run some of my VTK python code under ParaView (pvbatch or
	pvpython). Where can I find documentation on porting VTK python code to use
	ParaView python api? I need to create some VTK object in ParaView. Is there
	a shortcut to this (like being able to use VTK python api within ParaView
	Python environment)?  Or am I not making sense / asking the wrong question.

	Any help is much appreciated.

	Thanks
	-simon
