This doesn't change much: although at that point in time, weighted_point_3 was indeed not part of the kernel, the regular triangulation had the same parameters as it still does:

template < class Gt, class Tds_ = Default, class Lock_data_structure_ = Default >
class Regular_triangulation_3

Thus it would similarly be:

typedef CGAL::Regular_triangulation_euclidean_traits_3<K>  Traits;

typedef Traits::Weighted_point                              Weighted_point;

typedef CGAL::Triangulation_vertex_base_3<K> Vb0;

typedef CGAL::Triangulation_vertex_base_with_info_3<int, K, Vb0> Vb;

typedef CGAL::Regular_triangulation_cell_base_3<K> Cb;

typedef CGAL::Triangulation_data_structure_3<Vb,Cb> Tds;

typedef CGAL::Regular_triangulation_3<Traits, Tds>               Rt;

Rt rt;

Rt::Vertex_handle vh = rt.insert(..)

vh->info() = my_id;

Weighted_point wp = vh->point();

etc.

Nevertheless, I can only advise you to switch to a much more recent version so that you can benefit from the various improvements.

Hi, Mael.

I am now using CGAL with version  4.8.2, and I find that Weighted_point_3 is
not a member of 'CGAL::Epick', but a member of
'CGAL::Regular_triangulation_euclidean_traits_3'. 

Is there still an index associated to each of the vertices in the 4.8.2
version of CGAL? Or we can only fix this with a higher version of CGAL?

Thank you!

Best,
Baorong Yang
