Dear all,

in my last question I asked about Nef_polyhedra. by now I found out
that my problem was due to having an extended kernel.

So here is the next (hopefully more simple) question: Can I convert
geometric quantities in an easy way between different kernels?

I have:

typedef CGAL::Homogeneous<CGAL::Gmpz>  Kernel;
typedef CGAL::Extended_homogeneous<CGAL::Gmpz>  EKernel;
typedef Kernel::Plane_3  Plane_3;
typedef Kernel::Point_3    Point;
typedef Kernel::Vector_3  Vector_3;
typedef EKernel::Plane_3  EPlane_3;
typedef EKernel::Point_3    EPoint;
typedef EKernel::Vector_3  EVector_3;

Is there a simple way to convert a Plane_3 into a EPlane_3 (and the
same with vectors and points) and vice versa? 

Thanks for any help,

Martin.
