Detailed Description

Data class used in Poly_CoherentTriangultion. Implements a triangle with references to its neighbours.

Constructor & Destructor Documentation

◆ Poly_CoherentTriangle() [1/2]

Poly_CoherentTriangle::Poly_CoherentTriangle ( )

Empty constructor.

◆ Poly_CoherentTriangle() [2/2]

Member Function Documentation

◆ FindConnection()

Standard_Integer Poly_CoherentTriangle::FindConnection ( const Poly_CoherentTriangle ) const

Returns the index of the connection with the given triangle, or -1 if not found.

◆ GetConnectedNode()

Standard_Integer Poly_CoherentTriangle::GetConnectedNode ( const Standard_Integer  iConn) const
inline

Query the connected node on the given side. Returns -1 if there is no connection on the specified side.

◆ GetConnectedTri()

const Poly_CoherentTriangle* Poly_CoherentTriangle::GetConnectedTri ( const Standard_Integer  iConn) const
inline

Query the connected triangle on the given side. Returns NULL if there is no connection on the specified side.

◆ GetLink()

const Poly_CoherentLink* Poly_CoherentTriangle::GetLink ( const Standard_Integer  iLink) const
inline

Query the Link associate with the given side of the Triangle. May return NULL if there are no links in the triangulation.

◆ IsEmpty()

Standard_Boolean Poly_CoherentTriangle::IsEmpty ( ) const
inline

Query if this is a valid triangle.

◆ NConnections()

Standard_Integer Poly_CoherentTriangle::NConnections ( ) const
inline

Query the number of connected triangles.

◆ Node()

Standard_Integer Poly_CoherentTriangle::Node ( const Standard_Integer  ind) const
inline

Query the node index in the position given by the parameter 'ind'

◆ RemoveConnection() [1/2]

void Poly_CoherentTriangle::RemoveConnection ( const Standard_Integer  iConn)

Remove the connection with the given index.

Parameters
iConnCan be 0, 1 or 2 - index of the node that is opposite to the connection (shared link).

◆ RemoveConnection() [2/2]

Standard_Boolean Poly_CoherentTriangle::RemoveConnection ( Poly_CoherentTriangle theTri)

Remove the connection with the given Triangle.

Returns
True if successfuol or False if the connection has not been found.

◆ SetConnection() [1/2]

Standard_Boolean Poly_CoherentTriangle::SetConnection ( const Standard_Integer  iConn,
Poly_CoherentTriangle theTr 
)

Create connection with another triangle theTri. This method creates both connections: in this triangle and in theTri. You do not need to call the same method on triangle theTr.

Parameters
iConnCan be 0, 1 or 2 - index of the node that is opposite to the connection (shared link).
theTrTriangle that is connected on the given link.
Returns
True if successful, False if the connection is rejected due to improper topology.

◆ SetConnection() [2/2]

Standard_Boolean Poly_CoherentTriangle::SetConnection ( Poly_CoherentTriangle theTri)

Create connection with another triangle theTri. This method creates both connections: in this triangle and in theTri. This method is slower than the previous one, because it makes analysis what sides of both triangles are connected.

Parameters
theTriTriangle that is connected.
Returns
True if successful, False if the connection is rejected due to improper topology.
