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.
StraightSkeleton_2::Vertex | |
A model of the StraightSkeletonVertex_2 concept used to represent the vertices of the straight skeleton
| |
StraightSkeleton_2::Halfedge | |
A model of the StraightSkeletonHalfedge_2 concept used to represent the halfedges of the straight skeleton
| |
StraightSkeleton_2::Face | |
Any model of the StraightSkeletonFace_2 concept used to represent the faces of the straight skeleton
|
CGAL::Straight_skeleton_2<Traits,Items,Alloc>.
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.
