Concepts
concept	DelaunayTriangulationCellBase_3
	The base cell of a Delaunay triangulation must be a model of the concept DelaunayTriangulationCellBase_3, which refines the concept TriangulationCellBase_3 by adding in the cell an operator that computes its circumcenter. More...
concept	DelaunayTriangulationTraits_3
	The concept DelaunayTriangulationTraits_3 is the first template parameter of the class CGAL::Delaunay_triangulation_3. It defines the geometric objects (points, segments...) forming the triangulation together with a few geometric predicates and constructions on these objects. More...
concept	RegularTriangulationCellBase_3
	The regular triangulation of a set of weighted points does not necessarily have one vertex for each of the input points. Some of the input weighted points have no cell in the dual power diagrams and therefore do not correspond to a vertex of the regular triangulation. Those weighted points are said to be hidden points. A point which is hidden at a given time may appear later as a vertex of the regular triangulation upon removal on some other weighted point. Therefore, hidden points have to be stored somewhere. The regular triangulation stores those hidden points in its cells. More...
concept	RegularTriangulationCellBaseWithWeightedCircumcenter_3
	The concept RegularTriangulationCellBaseWithWeightedCircumcenter_3 refines the concept RegularTriangulationCellBase_3 by caching the weighted circumcenter of the cell. More...
concept	RegularTriangulationTraits_3
	The concept RegularTriangulationTraits_3 is the first template parameter of the class CGAL::Regular_triangulation_3. It defines the geometric objects (points, segments...) forming the triangulation together with a few geometric predicates and constructions on these objects. More...
concept	RegularTriangulationVertexBase_3
	The base vertex of a regular triangulation must be a model of the concept RegularTriangulationVertexBase_3, which refines the concept TriangulationDSVertexBase_3 by adding a geometric point member. More...
concept	TriangulationCellBase_3
	The cell base required by the basic triangulation does not need to store any geometric information, so only the requirements of the triangulation data structure apply. More...
concept	TriangulationCellBaseWithInfo_3
	A type model of this concept can be used as cell base by a triangulation and provides an additional information storage. More...
concept	TriangulationTraits_3
concept	TriangulationVertexBase_3
	The vertex base used by the geometric triangulation must store a point. We list here the additional requirements compared to a vertex base usable for the triangulation data structure. More...
concept	TriangulationVertexBaseWithInfo_3
	A type model of this concept can be used as vertex base by a triangulation and provides an additional information storage. More...
