Hello,
I am new to data visualisation and I want to visualise a simplicial complex generated from a python library called Gudhi.
What I have is a csv file that lists 3D coordinates and another list that contains cells as lists.
For example: I have a csv like this:
vertex\_no X Y Z
0 55.5 66.8 32.4
1 21.7 22.6 56.8
2 61.7 23.5 22.8
and so on…
Also I have another list of lists indicating the cells : [[0,1,2,5], [1,5,7,8], [2,3,4,8], [4,5,6,7],…]
where the entries of the lists refers to the vertex\_no.
I want to convert the list of cells to a cell data that I can use in paraview.
Kindly help.

Hi @arghya
That is quite specific. I see no other way but trough a programmable filter.
Best,
