gce_MakeHypr Class Reference

This class implements the following algorithms used to
create Hyperbola from gp.
* Create an Hyperbola from its center, and two points:
one on its axis of symmetry giving the major radius, the
other giving the value of the small radius.
The three points give the plane of the hyperbola.
* Create an hyperbola from its axisplacement and its
MajorRadius and its MinorRadius.

	gce_MakeHypr (const gp_Ax2 &A2, const Standard_Real MajorRadius, const Standard_Real MinorRadius)
	A2 is the local coordinate system of the hyperbola. In the local coordinates system A2 the equation of the hyperbola is : X*X / MajorRadius*MajorRadius - Y*Y / MinorRadius*MinorRadius = 1.0 It is not forbidden to create an Hyperbola with MajorRadius = MinorRadius. For the hyperbola the MajorRadius can be lower than the MinorRadius. The status is "NegativeRadius" if MajorRadius < 0.0 and "InvertRadius" if MinorRadius > MajorRadius.
	gce_MakeHypr (const gp_Pnt &S1, const gp_Pnt &S2, const gp_Pnt &Center)
	Constructs a hyperbola
const gp_Hypr &	Value () const
	Returns the constructed hyperbola. Exceptions StdFail_NotDone if no hyperbola is constructed.
const gp_Hypr &	Operator () const

Constructor & Destructor Documentation

gce_MakeHypr::gce_MakeHypr	(	const gp_Ax2 &	A2,
		const Standard_Real	MajorRadius,
		const Standard_Real	MinorRadius
	)

gce_MakeHypr::gce_MakeHypr	(	const gp_Pnt &	S1,
		const gp_Pnt &	S2,
		const gp_Pnt &	Center
	)

• centered on the point Center, where:
  

the plane of the hyperbola is defined by Center, S1 and S2,

• its major axis is defined by Center and S1,
  
• its major radius is the distance between Center and S1, and
  

its minor radius is the distance between S2 and the major axis.
Warning
If an error occurs (that is, when IsDone returns
false), the Status function returns:

• gce_NegativeRadius if MajorRadius is less than 0.0;
  
• gce_InvertRadius if:
  
  • the major radius (computed with Center, S1) is
    less than the minor radius (computed with Center, S1 and S2), or
    
  • MajorRadius is less than MinorRadius; or
    
• gce_ColinearPoints if S1, S2 and Center are collinear.
