Detailed Description

A tetrahedron in the topology. Implements the abstract methods from the parent classes to query the children, the vertices, the edges and faces of the tetrahedron.

Every face can have two different orientations in the tetrahedron (this is stored in the array rho – similar to the orientation of an edge in a triangle or quadrilateral, see geo_Triangle or qeo_Quadrilateral) and it can have three possible rotations (enumerating the vertices), stored in the array tau_.

Constructor & Destructor Documentation

◆ Tetrahedron()

concepts::Tetrahedron::Tetrahedron ( Triangle tri0,
Triangle tri1,
Triangle tri2,
Triangle tri3,
Attribute  attrib = Attribute() 
)

Constructor. Creates a tetrahedron out of four triangles. The faces must form a tetrahedron.

The first triangle is thought to be the floor of the tetrahedron and its normal orientation is right screwed into the tetrahedron. The normal orientation of the other three triangles (forming the walls of the tetrahedron) is right screwed out of the tetrahedron.

The walls of the tetrahedron must be given in the proper order: they must follow the normal orientation of the floor.

Parameters
tri0Floor of the tetrahedron
tri1..tri3Walls of the tetrahedron
attribAttribute of the tetrahedron

Member Function Documentation

◆ attrib()

const Attribute & concepts::Connector::attrib ( ) const
inlineinherited

Returns the attribute of the connector.

Definition at line 108 of file connector.hh.

◆ child() [1/2]

virtual const Tetrahedron * concepts::Tetrahedron::child ( uint  i) const
virtual

Implements concepts::Connector3.

◆ child() [2/2]

virtual Tetrahedron * concepts::Tetrahedron::child ( uint  i,
bool  mode = 0 
)
virtual

Returns a child.

If children are created, eight new children are created (with the same attributes as this one). All faces of the tetrahedron are refined and one new edge is introduced. This gives one new tetrahedron per vertex and one per face.

Parameters
iIndex of the child to be returned.
modemode = 1: No children are created
mode = 0: If no childs exist, eight new children are created.

Implements concepts::Connector3.

◆ edge()

Edge * concepts::Tetrahedron::edge ( uint  i) const
virtual

Returns a 1D component: edge. A 3D element consists of 2D, 1D and 0D elements, the edges can be queried here.

Parameters
iIndex of the edge

Implements concepts::Connector3.

◆ face()

Triangle * concepts::Tetrahedron::face ( uint  i) const
inlinevirtual

Returns a 2D component: face. A 3D element consists of 2D, 1D and 0D elements, the faces can be queried here.

Parameters
iIndex of the face

Implements concepts::Connector3.

Definition at line 73 of file topology3D.hh.

◆ info()

virtual std::ostream & concepts::Tetrahedron::info ( std::ostream &  os) const
protectedvirtual

Returns information in an output stream.

Reimplemented from concepts::Connector.

◆ key()

const Key & concepts::Connector::key ( ) const
inlineinherited

Returns the key of the connector.

Definition at line 105 of file connector.hh.

◆ operator==()

int concepts::Connector::operator== ( const Connector cntr) const
inlineinherited

Comparison operator.

Definition at line 102 of file connector.hh.

◆ related()

int concepts::Connector::related ( const Connector conn) const
inherited

Checks if this connector is related to conn. It is being checked if one of the two is an ancestor of the other.

Parameters
connOther connector
Returns
An integer i.
i=0 if there is no relationship or the connectors are identical
i>0 if conn is an ancestor of this connector
i<0 if conn is a descendant of this connector
|i| gives the number of generations between the connectors

◆ rho()

int concepts::Tetrahedron::rho ( int  i) const
inline

Returns the orientation of a face. See the description of rho_.

Parameters
iIndex of the face

Definition at line 79 of file topology3D.hh.

◆ setAttrib()

void concepts::Connector::setAttrib ( uint  attrb)
inlineinherited

Definition at line 111 of file connector.hh.

◆ tau()

int concepts::Tetrahedron::tau ( int  i) const
inline

Returns the rotation of a face. See the description of tau_.

Parameters
iIndex of the face

Definition at line 85 of file topology3D.hh.

◆ vertex()

Vertex * concepts::Tetrahedron::vertex ( uint  i) const
virtual

Returns a 0D component: vertex A 3D element consists of 2D, 1D and 0D elements, the vertices can be queried here.

Parameters
iIndex of the vertex

Implements concepts::Connector3.
