concept	ApolloniusGraphDataStructure_2
	The concept ApolloniusGraphDataStructure_2 refines the concept TriangulationDataStructure_2. In addition it provides two methods for the insertion and removal of a degree 2 vertex in the data structure. The insertion method adds a new vertex to the specified edge, thus creating two new edges. Moreover, it creates two new faces that have the two newly created edges in common (see figure below). The removal method performs the reverse operation. More...
concept	ApolloniusGraphHierarchyVertexBase_2
	The vertex of an Apollonius graph included in an Apollonius graph hierarchy has to provide some pointers to the corresponding vertices in the graphs of the next and preceding levels. Therefore, the concept ApolloniusGraphHierarchyVertexBase_2 refines the concept ApolloniusGraphVertexBase_2, by adding two vertex handles to the corresponding vertices for the next and previous level graphs.

concept	ApolloniusGraphTraits_2
concept	ApolloniusGraphVertexBase_2
	The concept ApolloniusGraphVertexBase_2 describes the requirements for the vertex base class of the ApolloniusGraphDataStructure_2 concept. A vertex stores an Apollonius site and provides access to one of its incident faces through a Face_handle. In addition, it maintains a container of sites. The container stores the hidden sites related to the vertex. More...
concept	ApolloniusSite_2
	The concept ApolloniusSite_2 provides the requirements for an Apollonius site class. More...
