Detailed Description

A Facet3 is one of the four sides (triangles) of a tetrahedron and it is represented by a Tet3 pointer and the opposite IntraTetIndex.

Constructor & Destructor Documentation

◆ Facet3()

FADE3D::Facet3::Facet3 ( Tet3 *  pTet_,
const int  opp3_ 
)
Parameters
pTet_is a pointer to a Tet3
opp3_selects the side of pTet

Member Function Documentation

◆ getEdge()

Edge3 FADE3D::Facet3::getEdge ( int  ith) const

Get the ith edge of the facet

Parameters
ith{0,1,2} selects the edge to be returned

◆ getIntraTetIndex()

int FADE3D::Facet3::getIntraTetIndex ( int  ith) const

Get the index of the ith vertex of the facet

◆ getOpp3Index()

int FADE3D::Facet3::getOpp3Index ( ) const

Get the IntraTetIndex

Returns
the IntraTetIndex of the tetrahedron which selects the side

◆ getTet()

Tet3* FADE3D::Facet3::getTet ( )

Get the Tet3

◆ operator!=()

bool FADE3D::Facet3::operator!= ( const Facet3 &  other) const

Check if two Facet3 objects refer to a different triangle

◆ operator==()

bool FADE3D::Facet3::operator== ( const Facet3 &  other) const

Check if two Facet3 objects refer to the same triangle

Returns
true if the present Facet3 and other refer to the same facet and false otherwise
Note
Inner facets of a triangulation are shared by two tetrahedra, thus the same facet can be expressed with two different Tet3 objects and opposite indices.
