CGAL 4.7 - 2D Segment Delaunay Graphs
|
The concept SegmentDelaunayGraphVertexBase_2
describes the requirements for the vertex base class of the SegmentDelaunayGraphDataStructure_2
concept. A vertex stores a site of the segment Delaunay graph and provides access to one of its incident faces through a Face_handle
.
