CGAL 4.3 - 2D Straight Skeleton and Polygon Offsetting
|
#include <CGAL/Straight_skeleton_builder_traits_2.h>
The class Straight_skeleton_builder_traits_2
provides a model for the StraightSkeletonBuilderTraits_2
concept which is the traits class required by the Straight_skeleton_builder_2
algorithm class.
The class Straight_skeleton_builder_traits_2
has one template argument: a 2D CGAL Kernel. This parameter must be a model for the Kernel
concept, such as the Exact_predicates_inexact_constructions_kernel
, which is the recommended one.
It is unspecified which subset of the kernel is used into the output sequence and the returned iterator will be equal to out
.
For any given input polygon, it in this traits class (and by extension in the builder class). This is to avoid restricting the choices in the implementation.
