#include <CGAL/Circular_kernel_2.h>

Inherits from

Kernel.

Definition

Is Model Of:
CircularKernel

Parameters

The first parameter of the circular kernel must be instantiated with a model of the Kernel concept. The Circular_kernel_2 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, AlgebraicKernelForCircles, is meant to provide the circular kernel with all the algebraic functionalities required for the manipulation of algebraic curves.

Types

The circular kernel uses basic number types of the algebraic kernel.

In fact, the two number types AlgebraicKernelForCircles::RT and Kernel::RT must coincide, as well as AlgebraicKernelForCircles::FT and Kernel::FT.

typedef
AlgebraicKernelForCircles::RT 		RT
 Ring number type. More...
 
typedef
AlgebraicKernelForCircles::FT 		FT
 Field number type. More...
 

The following types are available, as well as all the functionality on them described in the CircularKernel concept.

typedef Line_arc_2
< Circular_kernel_2 > 		Line_arc_2
 
typedef Circular_arc_2
< Circular_kernel_2 > 		Circular_arc_2
 
typedef Circular_arc_point_2
< Circular_kernel_2 > 		Circular_arc_point_2
