Arg. I'm really sorry about that.

I've updated the SO post with a full working example w/ all header includes & a cmake script to build it. It adds 3 vertices and inserts 1 face.

Because I am using this for terrain, I use x,y,z points and use the projection trait to allow for using this 3D point in a 2D triangulation. I've kept it this way as it may be of use to you.

The example on SO uses this triangulation data structure

I hope this helps,

Cheers

Chris

        Well, everyone can do a mistake, especially me. Still, thank you for
the answer on Stackoverflow and here, it does help.

        Thank you for this. I think there is still one line specific to your
code. I cannot compile it anyway. Here is the line:

typedef face<Gt> Fb; //custom face class, use default face and vertex as
required

        According to your comment, I should be using the default face class.
The thing is, I am discovering CGAL and I have not been able to find
which one I should use.

        Yes, indeed. Anyway, I do master the mesh formats I am dealing with.
Right now, my trouble is, I am discovering CGAL and as it is quite an
extensive library, I am still a bit lost in it.

        Once again, thank you for your answer.

        Best regards.
