Describes a branch of a hyperbola in 3D space. A hyperbola is defined by its major and minor radii and positioned in space with a coordinate system (a gp_Ax2 object) of which:  the origin is the center of the hyperbola,  the "X Direction" defines the major axis of the hyperbola, and  the "Y Direction" defines the minor axis of the hyperbola. The origin, "X Direction" and "Y Direction" of this coordinate system together define the plane of the hyperbola. This coordinate system is the "local coordinate system" of the hyperbola. In this coordinate system, the equation of the hyperbola is: X*X/(MajorRadius**2)Y*Y/(MinorRadius**2) = 1.0 The branch of the hyperbola described is the one located on the positive side of the major axis. The "main Direction" of the local coordinate system is a normal vector to the plane of the hyperbola. This vector gives an implicit orientation to the hyperbola. We refer to the "main Axis" of the local coordinate system as the "Axis" of the hyperbola. The following schema shows the plane of the hyperbola, and in it, the respective positions of the three branches of hyperbolas constructed with the functions OtherBranch, ConjugateBranch1, and ConjugateBranch2: ^YAxis  FirstConjugateBranch  Other  Main  C >XAxis Branch  Branch   SecondConjugateBranch  ^YAxis
Warning The major radius can be less than the minor radius. See Also gce_MakeHypr which provides functions for more complex hyperbola constructions Geom_Hyperbola which provides additional functions for constructing hyperbolas and works, in particular, with the parametric equations of hyperbolas
GHypr.GHypr  (  )

GHypr.GHypr  (  GAx2  theA2, 
double  theMajorRadius,  
double  theMinorRadius ) 
Creates a hyperbola with radius theMajorRadius and theMinorRadius, positioned in the space by the coordinate system theA2 such that:  the origin of theA2 is the center of the hyperbola,  the "X Direction" of theA2 defines the major axis of the hyperbola, that is, the major radius theMajorRadius is measured along this axis, and  the "Y Direction" of theA2 defines the minor axis of the hyperbola, that is, the minor radius theMinorRadius is measured along this axis. Note: This class does not prevent the creation of a hyperbola where:  theMajorAxis is equal to theMinorAxis, or  theMajorAxis is less than theMinorAxis. Exceptions Standard_ConstructionError if theMajorAxis or theMinorAxis is negative. Raises ConstructionError if theMajorRadius < 0.0 or theMinorRadius < 0.0 Raised if theMajorRadius < 0.0 or theMinorRadius < 0.0

GAx1 GHypr.Asymptote2  (  ) 
In the local coordinate system of the hyperbola the equation of the hyperbola is (X*X)/(A*A)  (Y*Y)/(B*B) = 1.0 and the equation of the first asymptote is Y = (B/A)*X. where A is the major radius and B is the minor radius. Raises ConstructionError if MajorRadius = 0.0
