Detailed Description

This class implements the following algorithms used to create a Dir from gp.

• Create a Dir parallel to another and passing through a point.
• Create a Dir passing through 2 points.
• Create a Dir from its axis (Ax1 from gp).
• Create a Dir from a point and a direction.

Constructor & Destructor Documentation

gce_MakeDir() [1/4]

gce_MakeDir::gce_MakeDir

(

const gp_Vec &

V

)

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

gce_MakeDir() [2/4]

gce_MakeDir::gce_MakeDir

(

const gp_XYZ &

Coord

)

Creates a direction from a triplet of coordinates. Status is "NullVector" if Coord.Modulus() <= Resolution from gp.

gce_MakeDir() [3/4]

gce_MakeDir::gce_MakeDir	(	const Standard_Real	Xv,
		const Standard_Real	Yv,
		const Standard_Real	Zv )

Creates a direction with its 3 cartesian coordinates. Status is "NullVector" if Sqrt(Xv*Xv + Yv*Yv + Zv*Zv) <= Resolution.

gce_MakeDir() [4/4]

gce_MakeDir::gce_MakeDir	(	const gp_Pnt &	P1,
		const gp_Pnt &	P2 )

Make a Dir 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:

• 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 + Zv*Zv).
