[Paraview] Paraview Python scripting

Tue Nov 1 10:24:55 EDT 2011

pvpython cannot be used for interactive viz (generally), it mostly designed
for batch. So it executes the script and then quits. Try adding a

raw_input()

at the end and the script will pause for input before exiting, giving you
an opportunity to look at the rendered result. Generally you'd edit the
script to add WriteImage() or somethign similar to generate screenshots or
save processed data out.

If you want to use it in an interactive fashion, you should stick with
Python Shell in the GUI.
