Hi All,

Does an efficient implementation to extract edges from a mesh of triangles without duplicates?

I mean:

- Vertices are a list of 3D points
- Triangles are a list of 3 indices pointing to vertices above

We want to find very quickly:

- A list of 2 indices representing the triangle sides but
*without*duplicates (of course, you always get two with opposite direction)

Thanks,

Alberto
