GCE2d_MakeHyperbola Class Reference

This class implements the following algorithms used to
create Hyperbola from Geom2d.
* Create an Hyperbola from two apex and the center.
Defines the main branch of an hyperbola.
The parameterization range is ]-infinite,+infinite[
It is possible to get the other branch and the two conjugate
branches of the main branch.

	GCE2d_MakeHyperbola (const gp_Hypr2d &H)
	Creates an Hyperbola from a non persistent one from package gp
	GCE2d_MakeHyperbola (const gp_Ax2d &MajorAxis, const Standard_Real MajorRadius, const Standard_Real MinorRadius, const Standard_Boolean Sense)
	MajorAxis is the "XAxis" of the hyperbola. The major radius of the hyperbola is on this "XAxis" and the minor radius is on the "YAxis" of the hyperbola. The status is "NegativeRadius" if MajorRadius < 0.0 or if MinorRadius < 0.0
	GCE2d_MakeHyperbola (const gp_Ax22d &Axis, const Standard_Real MajorRadius, const Standard_Real MinorRadius)
	Axis is the local coordinate system of the hyperbola. The major radius of the hyperbola is on this "XAxis" and the minor radius is on the "YAxis" of the hyperbola. The status is "NegativeRadius" if MajorRadius < 0.0 or if MinorRadius < 0.0
	GCE2d_MakeHyperbola (const gp_Pnt2d &S1, const gp_Pnt2d &S2, const gp_Pnt2d &Center)
	Creates a hyperbol centered on the origin of the coordinate system Axis, with major and minor radii MajorRadius and MinorRadius, where the major axis is the "X Axis" of Axis (Axis is the local coordinate system of the hyperbola). The implicit orientation of the ellipse is:
const Handle_Geom2d_Hyperbola &	Value () const
	Returns the constructed hyperbola. Exceptions: StdFail_NotDone if no hyperbola is constructed.

• the sense defined by Axis or H,
  
• the sense defined by points Center, S1 and S2,
  
• the trigonometric sense if Sense is not given or is true, or
  
• the opposite sense if Sense is false.
  Warning
  If an error occurs (that is, when IsDone returns
  false), the Status function returns:
  
• gce_NegativeRadius if MajorRadius or
  MinorRadius is less than 0.0, or
  
• gce_InvertAxis if the major radius defined by
  Center and S1 is less than the minor radius
  defined by Center, S1 and S2.Make an Hyperbola with its center and two apexes.
