Detailed Description

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).
  

Constructor & Destructor Documentation

gce_MakeDir2d::gce_MakeDir2d

(

const gp_Vec2d &

V

)

Normalizes the vector V and creates a direction.
Status is "NullVector" if V.Magnitude() <= Resolution.

gce_MakeDir2d::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::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::gce_MakeDir2d	(	const gp_Pnt2d &	P1,
		const gp_Pnt2d &	P2
	)

 Make a Dir2d from gp <TheDir> passing through 2 <br>
      Pnt <P1>,<P2>. <br>
      Status is "ConfusedPoints" if <P1> and <P2> are confused. <br>

Warning
If an error occurs (that is, when IsDone returns
false), the Status function returns:

• gce_ConfusedPoints if points P1 and P2 are coincident, or
  
• gce_NullVector if one of the following is less
  than or equal to gp::Resolution():
  
  • the magnitude of vector V,
    
  • the modulus of Coord,
    
  • Sqrt(Xv*Xv + Yv*Yv).
