[Paraview] Saving integrated data on an animated slice

[Richard GRENON]

Thanks, Adriano.

This seems to be a very good idea. I could attach a Programmable Filter 
script after my "Surface flow" filter.
My script should first create the data file with an "append" status so 
that it would not be overwritten at each animation step, then it should 
output the "Surface Flow" point value at each step. So maybe two 
Programmable Filter scripts? The first one before the animated Clip 
filter to create the output file, the second after the Surface flow 
filter. Maybe a pipeline like that:

- Programmable Filter 1 : Creates the output file with "append" status. 
Should execute once!
- Animated Clip : X coordinate of the cutting plane origin is animated.
- Surface Flow filter: performs integrations and gives a "Surface Flow" 
point value.
- Programmable Filter 2: write the "Surface Flow" value. Should execute 
at each animation step.

I will try to do that, but I am not very easy with Python, so if someone 
can help me to write these two scripts, thanks in advance.

Richard.
