The kernel that I use for de 3d Boolean Operations is defined by this code:

typedef CGAL::Homogeneous<CGAL::Gmpz>  Kernel;
typedef CGAL::Polyhedron_3<Kernel>  Polyhedron;
typedef CGAL::Nef_polyhedron_3<Kernel> Nef_polyhedron;

but y have a problem, because I need to convert this code:

typedef Kernel::Point_3  Point_3;

to a point of doubles as there: double vector[3], but this conversion
not is valid_

Point_3 pto;
double vector[3]

vector[0] = pto[0]; .... --> NOT VALID

The error that provoke this code:

c:\Archivos de programa\Cgal-3.2\examples\Nef_3\interface_polyhedron.C(114):
error C2440: '=' : no se puede realizar la conversión de
'CGAL::Homogeneous_base_ref_count<RT_,FT_,Kernel>::FT' a 'HDdouble'
        with
        [
            RT_=CGAL::Gmpz,
            FT_=CGAL::Quotient<CGAL::Gmpz>,
            Kernel=CGAL::Homogeneous<CGAL::Gmpz>
        ]


I need some help for convert a point of GMPZ Kernel to a Point of doubles.

Anyone can help me??????????????
