CGAL::Filtered_kernel_adaptor< CK > Class Template Reference

#include <CGAL/Filtered_kernel.h>

Definition

Filtered_kernel_adaptor is a kernel that uses the filtering technique from

[1] to obtain a kernel with exact and efficient predicate functors.

The geometric constructions are exactly those of the kernel CK, which means that they are not necessarily exact.

In contrast to Filtered_kernel, the global functions are those of CK.

Is Model Of:

Kernel

Example

The following example shows how to produce a kernel whose geometric objects and constructions are those of Simple_cartesian<double> The predicate functors of the kernel are exact, the global functions are not.

#include <CGAL/Simple_cartesian.h> 
#include <CGAL/Filtered_kernel.h> 

typedef CGAL::Simple_cartesian<double> CK; 
typedef CGAL::Filtered_kernel_adaptor<CK> K; 

typedef K::Point_2 p(0,0), q(1,1), r(1,5); 

CGAL::orientation(p,q,r); // not exact 

typedef K::Orientation_2 orientation; 
orientation(p,q,r); // exact
