Re: [Paraview] Get Values of CSV sources with Programmable Filter
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().

Hi Utkarsh, I already checked it, but there are no information about getting all values of VTKTable with NumPy. Now I'm using for-loops and the GetValue(i, j) function, but it's not smart. Do you have any other information?

Re: [Paraview] Get Values of CSV sources with Programmable Filter
If one of the inputs to the programmable filter is a table, you can values (columns) from it with something like: inputs[0].RowData['array_name'] This will give a (n,1) numpy array where n == number of rows.
