The class Min_ellipse_2_traits_2<K> is a traits class for CGAL::Min_ellipse_2<Traits> using the two-dimensional Cgal kernel.
#include <CGAL/Min_ellipse_2_traits_2.h>
The template parameter K is a model for Kernel.
| Min_ellipse_2_traits_2<K>::Point | |

| Min_ellipse_2_traits_2<K>::Ellipse | |
|
internal type.

The Ellipse type provides the following access methods not required by the concept MinEllipse2Traits.
| bool | ellipse.is_circle () | tests whether the ellipse is a circle. |
| void | ellipse.double_coefficients ( double &r, double &s, double &t, double &u, double &v, double &w) | |
| gives a double approximation of the ellipse's conic equation. If K is a Cartesian kernel, the ellipse is the set of all points (x,y) satisfying rx2+sy2+txy+ux+vy+w=0. In the Homogeneous case, the ellipse is the set of points (hx,hy,hw) satisfying r(hx)2+s(hy)2+t(hx)(hy)+u(hx)(hw)+v(hy)(hw)+w(hw)2=0. | ||
