Definition

template<typename Kernel, typename AlgebraicKernelForSpheres>
struct CGAL::Spherical_kernel_3< Kernel, AlgebraicKernelForSpheres >

Is model of: SphericalKernel

Parameters

The first parameter of the spherical kernel must be instantiated with a model of the Kernel concept. The Spherical_kernel_3 class template derives from this first parameter, in order to reuse all needed functionalities on basic objects provided by a model of the Kernel concept.

The second parameter, AlgebraicKernelForSpheres, is meant to provide the spherical kernel with all the algebraic functionalities required for the manipulation of algebraic curves.

Types
The spherical kernel uses basic number types of the algebraic kernel: In fact, the two number types `AlgebraicKernelForSpheres::RT` and `Kernel::RT` must refer to the same type, as well as `AlgebraicKernelForSpheres::FT` and `Kernel::FT`.
typedef AlgebraicKernelForSpheres::RT	RT
	Ring number type.

typedef AlgebraicKernelForSpheres::FT	FT
	Field number type.

The following types are available, as well as all the functionality on them described in the `SphericalKernel` concept. `Polynomials_for_circle_3` is implemented as a `std::pair< Polynomial_for_spheres_2_3, Polynomial_1_3 >` and is a model of `AlgebraicKernelForSpheres::PolynomialsForCircles_3`.
typedef Line_arc_3< Spherical_kernel_3 >	Line_arc_3

typedef Circular_arc_3< Spherical_kernel_3 >	Circular_arc_3

typedef Circular_arc_point_3< Spherical_kernel_3 >	Circular_arc_point_3
