CGAL 5.2.1 - 2D Straight Skeleton and Polygon Offsetting



The concept StraightSkeleton_2 describes the requirements for the data structure used to represent a straight skeleton. It refines the concept HalfedgeDS and adds additional requirements on the nested types Vertex, Halfedge, and Face of the halfedge data structure.

Has Models:
This concept explicitly protects all the modifying operations of the base HalfedgeDS concept. Only the algorithm classes, or clients explicitly bypassing the protection mechanism, can modify a straight skeleton.


typedef unspecified_type Vertex
 A model of the StraightSkeletonVertex_2 concept used to represent the vertices of the straight skeleton.
typedef unspecified_type Halfedge
 A model of the StraightSkeletonHalfedge_2 concept used to represent the halfedges of the straight skeleton.
typedef unspecified_type Face
 Any model of the StraightSkeletonFace_2 concept used to represent the faces of the straight skeleton.
