## Concepts
concept | ConformingDelaunayTriangulationTraits_2
| The concept `ConformingDelaunayTriangulationTraits_2` refines the concept `ConstrainedDelaunayTriangulationTraits_2` by providing a numeric field type `FT`, a type `Vector_2` and several constructors on `Vector_2`, `Point_2`, and a predicate on angles. The field type has to be a model of the concept `FieldWithSqrt`. This field type and the constructors are used by the conforming algorithm to compute Steiner points on constrained edges. More...
concept | DelaunayMeshFaceBase_2
| The concept `DelaunayMeshFaceBase_2` refines the concept `TriangulationFaceBase_2`. It adds two functions giving access to a Boolean marker, that indicates if the face is in the meshing domain or not. More...
concept | DelaunayMeshTraits_2
| The concept `DelaunayMeshTraits_2` refines the concept `ConformingDelaunayTriangulationTraits_2`. It provides a construction object `Construct_circumcenter_2`. More...
concept | DelaunayMeshVertexBase_2
| The concept `DelaunayMeshVertexBase_2` refines the concept `TriangulationVertexBase_2`. It adds two functions giving access to a `double` marker, that is useful for the mesh optimizers to keep the mesh density everywhere while modifying the mesh. More...
concept | MeshingCriteria_2
| The concept `MeshingCriteria_2` defines the meshing criteria to be used in the algorithm. It provides a predicate `Is_bad` that tests a triangle according to criteria. The return type of `Is_bad` is an enum `Mesh_2::Face_badness`. More...
