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'

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.

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::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.

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.
