CGAL 5.1.2 - 2D Apollonius Graphs (Delaunay Graphs of Disks)

#include <CGAL/Apollonius_graph_traits_2.h>
The class Apollonius_graph_traits_2
provides a model for the ApolloniusGraphTraits_2
concept.
This class has two template parameters. The first template parameter must be a model of the Kernel
concept. The second template parameter corresponds to how predicates are evaluated. There are two predefined possible values for Method_tag
, namely CGAL::Field_with_sqrt_tag
and CGAL::Integral_domain_without_division_tag
. The first one must be used when the number type used in the representation supports the exact evaluation of signs of expressions involving all four basic operations and square roots, whereas the second one requires the exact evaluation of signs of ring-type expressions, i.e., expressions involving only additions, subtractions and multiplications. The default value for Method_tag
is CGAL::Integral_domain_without_division_tag
. The way the predicates are evaluated is discussed in [3], [4].
