Hi, I am trying to access the full_cell of a regular triangulation RT, and my
code is as follows:
 
/////////////////////

#include <CGAL/Exact_predicates_inexact_constructions_kernel.h>
#include <CGAL/Regular_triangulation_3.h>
#include <CGAL/Regular_triangulation_cell_base_3.h>
#include <CGAL/Triangulation_vertex_base_3.h>
#include <CGAL/Triangulation_vertex_base_with_info_3.h>
class RtVertexInfo
{
public:
        unsigned id;
};

typedef CGAL::Exact_predicates_inexact_constructions_kernel K;
typedef K::FT                                                                 
                                          Weight;
typedef K::Point_3                                                            
                                          RTPoint;
typedef K::Weighted_point_3                                                   
                                  Weighted_point;
typedef CGAL::Regular_triangulation_vertex_base_3<K>                          
  Vb0;
typedef CGAL::Triangulation_vertex_base_with_info_3<RtVertexInfo, K, Vb0>
RtVb;
typedef CGAL::Regular_triangulation_cell_base_3<K>                            
          RtCb;
typedef CGAL::Triangulation_data_structure_3<RtVb, RtCb>                      
  RtTds;
typedef CGAL::Regular_triangulation_3<K, RtTds>                               
          Regular_Triangulation;

typedef Regular_Triangulation::Finite_facets_iterator                         
  
Finite_facets_iterator; 
typedef Regular_Triangulation::Finite_edges_iterator                          
  
Finite_edges_iterator; 
typedef Regular_Triangulation::Finite_vertices_iterator                       
  
Finite_vertices_iterator; 
typedef Regular_Triangulation::Face_circulator                                
          Facet_circulator;
typedef Regular_Triangulation::Cell_handle                                    
                  Cell_handle;
typedef Regular_Triangulation::Vertex_handle                                  
          Rt_Vertex_handle;
//typedef RtTds::Full_cell_const_iterator                                     
                  Full_cell_const_iterator;

////////////

However, when I was trying to define the Full_cell_const_iterator as the
last line of my code which I have comment out, it shows that
Full_cell_const_iterator is not a member of Triangulation_data_structure_3.

I am wondering what's the matter with my code and how I can access the
Full_cell of the regular triangulation.

The other problem is that when I tried computing the regular triangulation
with a set of spheres, it will fails at inserting some spheres. And I
believe that the sphere should be conflict with some boundary cells of the
triangulation. How can I handle this kind of problem then?

I would be appreciate that someone can help me with these problems.

Thank you!

Best,
Baorong Yang
