[Paraview] Programmable filter - script for mean of two input PointSources

[Jonathan Borduas]

Hi, 

What is the best way to proceed if someone wants to use the new coordinate (mean of the two dots) in another filter using a Link. For instance, I would like to use the coordinate as the Origin of a Clip filter. 

Thank you,

Here's a simple trick:

1. Select both point sources in pipeline browser and then create the "Python Calculator".
2. Use the expression "(inputs[0].Points + inputs[1].Points)/2.0", and hit "Apply"
3. Next, create the "Calculator" filter connect to the "Python Calculator" with expression "result" and also check the "Coordinate Results" checkbox. Hit "Apply".

That should do it.

Example state file attached.
