[Paraview] Get Values of CSV sources with Programmable Filter

[Magician]

Hi Berk,


Thanks for your reply.

Hmmm...
My purpose is extracting CSVs to vtkImageData with the Programmable Filter.
And the CSVs don't have headers, so it's not so good idea for me to get values per columns.
If possible, I want to get the values as 2D numpy.array directly as numpy.loadtxt().
