[Paraview-developers] Python programmable source acting as filereader

[Daan van Vugt]

Hi,

I would like to create a plugin that uses h5py and numpy to read a file, do
some operations on it and return VTK objects.
Would it be possible to do the same thing as
http://www.paraview.org/Wiki/Animating_legacy_VTK_file_series#Making_custom_readers_work_with_file_series
but instead of using a vtkPDataSetReader use a vtkPythonProgrammableSource?

I have made a (very naive) try, attached to this post.
When using this to read a series of files I get the errors (version 5.2.0
64-bit) shown below.
To test, just use any hdf5 file. (.h5)

Thanks for any help,
Daan
