Member Function Documentation

Standard_Integer Poly_CoherentTriangle::FindConnection

(

const Poly_CoherentTriangle &

)

const

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

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.

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.

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.

Standard_Boolean Poly_CoherentTriangle::IsEmpty ( ) const

inline

Set the Node at the given position 'ind'. Query if this is a valid triangle.

Standard_Integer Poly_CoherentTriangle::NConnections ( ) const

inline

Query the number of connected triangles.

Standard_Integer Poly_CoherentTriangle::Node ( const Standard_Integer  ind ) const

inline

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

void Poly_CoherentTriangle::RemoveConnection

(

const Standard_Integer

iConn

)

Remove the connection with the given index.

Parameters

iConn

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

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.

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

iConn	Can be 0, 1 or 2 - index of the node that is opposite to the connection (shared link).
theTr	Triangle that is connected on the given link.

Returns

True if successful, False if the connection is rejected due to improper topology.

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

theTri

Triangle that is connected.

Returns

True if successful, False if the connection is rejected due to improper topology.
