[Paraview] [EXT] Re: Details of XML filter with lists of input arrays

[Utkarsh Ayachit]

Dennis,

Here's a example. You need manually modify the XML generated using
[1]. I've attached script.xml with my modifications to add a new
property for "Arrays".
Also attached a state file that demos this filter (load state after
lading the script.xml as plugin).

Hope that helps.
Utkarsh

[1]  `python python_filter_generator.py script.py script.xml`

I'm hoping this can be similar to plugins I have written with hardcoded variable names where I've used something like:
