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

Hi Seb,

Thanks. Good point. I have assumed I am dealing with parallel code. Let me 
check up on that.

Basically the whole purpose of this exercise is to have the simulation code 
generate the data and visualize the data in real time (ParaView + catalyst).

If the code is not parallel, maybe we can just skip ParaView completely and 
just use VTK to pop up the window and do the rendering when the data is 
generated?

Or if the code is not parallel, we should change all the VTK python code into 
ParaView python code? And run it with pvpython.

Which option would be the right way to do thing?

Or if the code is parallel, then the only option is to change the VTK code 
into ParaView code?

Thanks
-simon

Hi Simon,

if the VTK work that you are targeting is not parallel, you can directly run a 
vtkpython script inside pvpython or pvbatch.
Otherwise Andy is right, you can not mix parallel ParaView and VTK python 
code.

	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
