CGAL 4.8.1 - 2D Straight Skeleton and Polygon Offsetting
|
#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
SrcSs | type of the source straight skeleton |
TgtSs | type of the target straight skeleton |
ItemsCvt | a 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.
Types | |
SrcSs | Source_skeleton |
The SrcSs template parameter corresponding to the source straight skeleton. | |
TgtSs | Target_skeleton |
The TgtSs template parameter corresponding to the target straight skeleton. | |
ItemsCvt | Items_converter |
The ItemsCvt template parameter corresponding to the items converter. | |
Creation | |
Straight_skeleton_converter_2 (Items_converter const &c) | |
Default constructor . | |
Operations | |
boost::shared_ptr < Target_skeleton > | operator() (Source_skeleton const &s) const |
returns a new straight skeleton data structure with the same combinatorial and geometric data as s using the items converter to convert the geometric embeeding to the types of the target traits. | |
