Dear everyone,
I would have a set of 3D points in space (divided by unique Id of line and ordered by ascending X), which I would like to connect with a 3D line. Is there a way to use this points to visualise a set of 3D lines?
Probably a Programmable Source might do the job…
The structure of the points that I have in the source csv is:
ID, X, Y, Z
and ideally I wanted to connect the points with the same ID with a line
Is there a way to do so?
Thank you in advance

You can read your `CSV` with ParaView natively to load the data and then use a `Programmable Filter` to create the lines. You will write vtk python code to create a `vtkCellArray`, fill some `vtkIdLists` with the points ids for each line (id is the index in list of poitns, different from you ID column) and then create `VTK_POLY_LINE` cells.
[Here](https://docs.paraview.org/en/latest/ReferenceManual/pythonProgrammableFilter.html#reading-a-csv-file-with-particles) are some examples of programmable filters.
