[Paraview] How to determine that some points are inside some closed surfaces or not ?

[hengxing pan]

Hi, Cory
I have tried to take out the points inside a tube to lines in the same
programmable filter as you, but it turns out that there are always some
points outside the tube which the filter can not get rid of. I have made a
small example for you. Do you have any idea about this situation ?
