Member Function Documentation

Standard_EXPORT 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]

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_EXPORT 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_EXPORT 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_EXPORT 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_EXPORT 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.
