[Paraview] Defining edge in Paraview

[Ankush Aggarwal]

 Hi all,

 Lets say I have a surface polygonal (triangular) mesh. I want to add to 
 it a point data saying 1 if the point is on the edge and 0 otherwise. Is 
 it possible to do in Paraview?

 I know I can feature the edges and I get a separate object with (fewer) 
 edge nodes and line elements connecting them. But I can't use that 
 directly in my code.

 Thanks in advance!
