gce_MakeDir2d Class Reference

This class implements the following algorithms used
to create a Dir2d from gp.
* Create a Dir2d with 2 points.
* Create a Dir2d with a Vec2d.
* Create a Dir2d with a XY from gp.
* Create a Dir2d with a 2 Reals (Coordinates).

Public Member Functions
void *	operator new (size_t, void *anAddress)
void *	operator new (size_t size)
void	operator delete (void *anAddress)
	gce_MakeDir2d (const gp_Vec2d &V)
	Normalizes the vector V and creates a direction. Status is "NullVector" if V.Magnitude() <= Resolution.
	gce_MakeDir2d (const gp_XY &Coord)
	Creates a direction from a triplet of coordinates. Status is "NullVector" if Coord.Modulus() <= Resolution from gp.
	gce_MakeDir2d (const Standard_Real Xv, const Standard_Real Yv)
	Creates a direction with its 3 cartesian coordinates. Status is "NullVector" if Sqrt(Xv*Xv + Yv*Yv ) <= Resolution
	gce_MakeDir2d (const gp_Pnt2d &P1, const gp_Pnt2d &P2)
	Make a Dir2d from gp <TheDir> passing through 2 Pnt <P1>,<P2>. Status is "ConfusedPoints" if <P1> and <P2> are confused. Warning If an error occurs (that is, when IsDone returns false), the Status function returns:
const gp_Dir2d &	Value () const
	Returns the constructed unit vector. Exceptions StdFail_NotDone if no unit vector is constructed.
const gp_Dir2d &	Operator () const
	operator gp_Dir2d () const
