[Paraview] [EXTERNAL] Re: CSV to PVTU

[Faiz Abidi]

I see.

I did that because when I choose "Assign Cells Uniquely" as the "Boundary
Mode" in the D3 filter, I was getting a warning like below:

Warning: In /home/faiz89/git/ParaView/VTK/Common/DataModel/vtkKdTree.cxx,
line 1887
vtkKdTree (0x2db5950): vtkKdTree::BuildMapForDuplicatePoints - invalid
tolerance

But in spite of the warning, 8 vtu files get generated along with 1 pvtu
file. So, maybe that warning can be ignored.
