Dear Manuel,

thank you for help!

Now I have problem, when I am trying to insert points.

I do it like this:

typedef CGAL::Exact_predicates_inexact_constructions_kernel K;

typedef CGAL::Regular_triangulation_filtered_traits_2<K> Traits;

typedef CGAL::Triangulation_vertex_base_with_info_2<int, K> Vb;

typedef CGAL::Regular_triangulation_face_base_2<K> Fb;

typedef CGAL::Triangulation_data_structure_2<Vb, Fb> Tds;

typedef CGAL::Regular_triangulation_2<Traits, Tds> RegularTr;

        typedef K::Point_2 Point;

typedef RegularTr::Weighted_point WPoint;

        .....

RegularTr T;

WPoint wp(Point(1,2), 2);

T.insert(wp);  // If delete this line - no compiler errors !!!

I tried to modify type of Kernel and way how I define Weighted_point, but it doesn't work

Could you please help me?

Hello everyone !

Is it possible to have weighted Delaunay triangulation with info with using CGAL ?

And am I correct that CGAL regular triangulation of a set of weighted points gives me weighted Delaunay ? ...but how to add info to it, I don't know

sorry I forgot: yes, the CGAL regular triangulations correspond to weighted Delaunay triangulations.

Can you help me, please?

Thank you.
