Detailed Description

An Edge3 is represented by a Tet3 pointer and two two IntraTetIndices opp3 and opp2. The Edge of the tetrahedron is selected as follows: At first, opp3 selects the facet (triangle) of the tetrahedron opposite to the corner addressed by opp3. Then opp2 selects the edge in this triangle opposite to the vertex at position opp2. See the image where opp3=3 and opp2=0. The edge proceeds from corner 1 to corner 2.

Edge (0,1) of a tetrahedron, selected by opp3=3 and opp2=0

Constructor & Destructor Documentation

◆ Edge3()

FADE3D::Edge3::Edge3	(	Tet3 *	pTet_,
		const int	opp3_,
		const int	opp2_
	)

Parameters

pTet_	Tetrahedron
opp3_	selects one of the four triangles of the tetrahedron
opp2_	selects one of the edges of the triangle

Member Function Documentation

◆ getSourceIndex()

int FADE3D::Edge3::getSourceIndex ( ) const

Returns: the index of the tetrahedron which selects the source vertex of the edge

◆ getTargetIndex()

int FADE3D::Edge3::getTargetIndex ( ) const

Returns: the index of the tetrahedron which selects the target vertex of the edge

◆ operator!=()

bool FADE3D::Edge3::operator!= ( const Edge3 & rhs ) const

Two Edge3 objects are different when they do not refer to the same undirected edge.

◆ operator==()

bool FADE3D::Edge3::operator== ( const Edge3 & rhs ) const

Two edges are equal when their vertices coincide (undirected edge) even if the two objects use different tetrahedra that meet on this edge.
