Hi,

Thanks for this. Reverting what I said yesterday, it is actually
segment/segment intersection I need, because I need to know precisely which
segments of the linestrings intersects.

Anyway, trying to compile :

std::vector<ggl::point_2d> intersected;
>
> ggl::intersection < ggl::point_2d, ggl::segment, ggl::segment,
> std::back_insert_iterator< std::vector<ggl::point_2d> > >
>
> (s1, s2, std::back_inserter(intersected));
>

I receive, under GCC:

> error: no matching function for call to
> `intersection(ggl::segment<ggl::point_2d>&, ggl::segment<ggl::point_2d>&,
> std::back_insert_iterator<std::vector<ggl::point_2d,
> std::allocator<ggl::point_2d> > >)'
>

Any idea?
