CGAL 5.4 - 2D Arrangements

#include <CGAL/Arr_linear_traits_2.h>
The traits class Arr_linear_traits_2
is a model of the ArrangementTraits_2
concept, which enables the construction and maintenance of arrangements of linear objects.
The linear objects may be bounded (line segments) or unbounded (rays and lines). Thus, it is also a model of the concept ArrangementOpenBoundaryTraits_2
. The traits class is parameterized parameterized with a CGAL-kernel model; see the reference page of Arr_segment_traits_2<Kernel>
for further explanations and recommendations on choosing a kernel.
Arr_linear_traits_2
defines Kernel::Point_2
as its point type. The nested X_monotone_curve_2
and Curve_2
types defined by the traits class (as is the case with the various segment-traits classes, both types refer to the same class, as every linear object is (weakly) \( x\)-monotone), are constructible from a point, a line segment, a ray and from a line (objects of types Kernel::Point_2
, Kernel::Segment_2
, Kernel::Ray_2
and Kernel::Line_2
, respectively). On the other hand, when we are given a curve we can find out its actual type and convert it to the respective kernel object (say, to a Kernel::Ray_2
).
