CGAL::Straight_skeleton_converter_2< SrcSs, TgtSs, ItemsCvt > Class 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.

The third template parameter ItemsConverter is a function object that must

Template Parameters
SrcSstype of the source straight skeleton
TgtSstype of the target straight skeleton
ItemsCvta model StraightSkeletonItemsConverter_2. The default value of this parameter is Straight_skeleton_items_converter_2<SrcSs,TgtSs>.

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