[Paraview] Filter for interactive spreadsheet?

[Andy Bauer]

Hi Cornelis,

How would you like to select the single or group of values to change? Also,
how would you like to change them (e.g. the same transformation for each or
each with its own transformation)? These two questions are meant to guide
you to do what you want in ParaView.

You probably want to look at the Python Programmable Filter (
http://www.paraview.org/Wiki/Python_Programmable_Filter) for changing
individual array values. If you are working in serial you may also be able
to bring in the entities to change based on a selection. A better solution
would be to use the global ids filter, then do a selection on what you want
and finally pass that in as a secondary input to the Python Programmable
filter.

Developing your own filter is also a possibility.

cheers,
Andy
