[Paraview] ParaView and Python general questions

[Eric E. Monson]

Hey Milos,

Someone else may have to address your specific concerns about loading opacity functions, axes and rotation center, but I wanted to make sure you know about some very helpful functionality for figuring out the way to do things in Python. In 3.6 there was already a Python "Trace" function where you can start a trace, then do GUI manipulations, and then show or save the trace and look at the Python commands for what you did. I would advise upgrading to 3.8, though, as there is now a "Trace State" button on the Python shell which lets you set up a pipeline and then get the Python commands which will (should) set up the same pipeline.

For automating things you'll probably still need to refer to the wiki page for some things. I think that's the most up-to-date documentation:

http://www.paraview.org/Wiki/ParaView/Python_Scripting

Hopefully someone else can help with your more specific needs,
-Eric

I haven't been able to find detailed documentation, except for the "ParaView Scripting with Python" document, and by looking at the properties of the Python modules using dir, help, etc, it is very hard to find out how some things are done and I have to admit that I am a bit lost. I was wondering if a more comprehensive guide than this document and the 'Python Recipes' page exists, or at least some guidelines on how to find out how things are done from the servermanager module.
