CGAL 5.4.1 - 2D Straight Skeleton and Polygon Offsetting
CGAL::Straight_skeleton_converter_2< Source_skeleton_, Target_skeleton_, Items_converter_ > Struct Template Reference

#include <CGAL/Straight_skeleton_converter_2.h>


The class Straight_skeleton_converter_2 converts a straight skeleton instantiated using certain traits into another straight skeleton instantiated using a different traits.

Template Parameters
Source_skeleton_type of the source straight skeleton
Target_skeleton_type of the target straight skeleton
Items_converter_a model StraightSkeletonItemsConverter_2. The default value of this parameter is Straight_skeleton_items_converter_2<Source_skeleton_,Target_skeleton_>.

This conversion can be used to produce a straight skeleton using a kernel without exact constructions (such as Exact_predicates_inexact_constructions_kernel) but input that skeleton into Polygon_offset_builder<Ss,Gt,Container> instantiated with a slower kernel (such as Exact_predicates_exact_constructions_kernel) thus obtaining only simple offset polygons without paying the runtime overhead of exact constructions for the straight skeleton itself.
