Re: [Paraview] Programmable filter, looping over time steps and reimporting inputs
Thanks Utkarsh for your reply. I've gone through the blog a few times
already but I still don't understand the whole procedure. I even tried
to just run the example in the blog in a Programmable Source but it
doesn't work ('No module named numpy_interface'). Part of the issue
could be that I still don't fully understand the RequestInformation,
RequestUpdateExtent, and RequestData bits of the filter.
The input data that I'm working on in the pipeline (vtk unstructured
grid) already have different time steps. How can I update the values of
the inputs for the different time steps?
Thank you,
Omid

It should give you information on what you need to put in the Scripts
for various passes of the filter.

Hi,
I'm writing a python script for the Programmable Filter of

done over time steps (perhaps similar to integrate over time
filter). All bits of my script are working fine. However, after
spending a considerable amount of time on fiddling with the
script, googling, reading mailing lists and the VTK documentation,
I haven't found a way to loop over time steps AND update the
input from within the script. I can loop over time steps using:
from vtk import vtkStreamingDemandDrivenPipeline
for time in
outInfo.Get(vtkStreamingDemandDrivenPipeline.TIME_STEPS()):
#Perform some analysis, for instance subtracting value_v
for this time from value_v at time zero...
However, the input data is still from the time step where I first
applied the script. Of course, when I animate the results, the
inputs will be updated, but I will need to achieve the same
results from within my script in the Programmable Filter dialogue.
How can I update the inputs from within my for loop or how can I
modify the for loop or my script to achieve that? Can Programmable
Filter handle my situation? If not, what is the alternative?
Many thanks,
Omid
