Menelaos Karavelas
An algorithm for computing the dual of a Voronoi diagram of a set of segments under the Euclidean metric. It is a generalization of the standard Voronoi diagram for points. The algorithms provided are dynamic.
Introduced in: CGAL 3.1
Depends on: 2D Triangulation Data Structure

CGAL provides the class `CGAL::Segment_Delaunay_graph_2<Gt,St,DS>` for computing the 2D Delaunay graph of segments and points. The two template parameters must be models of the `SegmentDelaunayGraphTraits_2` and `SegmentDelaunayGraphDataStructure_2` concepts. The first concept is related to the geometric objects and predicates associated with segment Delaunay graphs, whereas the second concept refers to the data structure used to represent the segment Delaunay graph, which is dual to the 2D Voronoi diagram of segments and points. The classes `CGAL::Segment_Delaunay_graph_traits_2<K,MTag>`, `CGAL::Segment_Delaunay_graph_traits_without_intersections_2<K,MTag>` `CGAL::Segment_Delaunay_graph_filtered_traits_2<K,MTag>` `CGAL::Segment_Delaunay_graph_filtered_traits_without_intersections_2<K,MTag>` are models of the `SegmentDelaunayGraphTraits_2` concept, whereas the class `CGAL::Triangulation_data_structure_2<Vb,Fb>` is a model of the `SegmentDelaunayGraphDataStructure_2` concept.
