CGAL 5.3  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 CGALkernel 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 segmenttraits 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
).

class  Curve_2 
The Curve_2 (and the X_monotone_curve_2 ) class nested within the lineartraits can represent all types of linear objects. More...
