Definition

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.

◆ Edge

typedef std::pair<DelaunayMeshFaceBase_2, int> DelaunayMeshFaceBase_2::Edge

A typedef to describe an edge.

Member Function Documentation

◆ blinding_constraint()

Edge DelaunayMeshFaceBase_2::blinding_constraint ( ) const

If this face is blind, this function returns the first constrained edge that prevents it from "seeing" its circumcenter.

Precondition: is_blind() returns true

◆ is_blind()

bool DelaunayMeshFaceBase_2::is_blind ( ) const

returns true if this face has its circumcenter hidden by a constrained edge.

It does not "see" it, following the Constrained Delaunay triangulation visibility criterion.

◆ is_in_domain()

bool DelaunayMeshFaceBase_2::is_in_domain ( ) const

returns true if this face is in the domain to be refined.

◆ set_blind()

void DelaunayMeshFaceBase_2::set_blind ( const bool b )

sets if this face is blind or not.

◆ set_blinding_constraint()

void DelaunayMeshFaceBase_2::set_blinding_constraint ( const Egde & e )

sets the edge that makes this face blind.

Precondition: is_blind() returns true; e is a constrained edge

◆ set_in_domain()

void DelaunayMeshFaceBase_2::set_in_domain ( const bool b )

sets if this face is in the domain.
