Hello,

I am working on selecting and extracting a subset of lines from a
vtkpolydata (PD) that pass through a vtkpoints (selectionPoints). How can I
access to indices of selected lines? Also based on below code, output of
loop is an empty polydata!

Here is my sample code:

loop = vtk.vtkSelectPolyData()
loop.SetInputData(PD)
loop.SetLoop(selectionPoints)
loop.GenerateSelectionScalarsOff()

I would appreciate any help.

Best,
Saeed
