[Paraview] Programmable Source & MultiBlockDataSet

[Aurélien Marsan]

I found a solution to do what I wanted to do. Not really elegant, but it
works.
The best would be to encode the reader in the source code.... but I don't
know how to do, and have no time for now.

First, I use the tool Source -> Data Object Generator, and create a
MultiBlockDataSet.

> MB{}


Then, I use a Programmable Filter, and set the Output Data Type "Same as
Input".
So I can use this script.


> from Moduleperso import *
> m = MultiBlocFromV3D(........)       # This is a personnal reader in
> python, that returns a vtkMultiBlockDataSet
> self.GetOutputDataObject(0).DeepCopy(m)
>

Hope this will help some people who don't want to go in source code...
