class MakeHyperbola from GC inherits Root from GC

    ---Purpose :This class implements construction algorithms for a hyperbola in
    -- 3D space. The result is a Geom_Hyperbola hyperbola.
    -- A MakeHyperbola object provides a framework for:
    -- -   defining the construction of the hyperbola,
    -- -   implementing the construction algorithm, and
    -- -   consulting the results. In particular, the Value
    --   function returns the constructed hyperbola.
    --  To define 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.

    --  The major radius is the distance between the Location point
    --  of the hyperbola C and the apex of the Main Branch (or the
    --  Other branch). The major axis is the XAxis.
    --  The minor radius is the distance between the Location point
    --  of the hyperbola C and the apex of the First (or Second)
    --  Conjugate branch. The minor axis is the YAxis.
    --  The major radius can be lower than the minor radius.

Create (H : Hypr from gp)   returns MakeHyperbola;
    --- Purpose :
    --  Creates  an Hyperbola from a non persistent hyperbola  from package gp by conversion.

Create (A2 : Ax2                        from gp      ; 
    	MajorRadius, MinorRadius : Real from Standard) returns MakeHyperbola;
    --- Purpose : Constructs a hyperbola centered on the origin of the coordinate system
    -- A2, with major and minor radii MajorRadius and MinorRadius, where:
    --   the plane of the hyperbola is defined by the "X Axis" and "Y Axis" of A2,
    --   -   its major axis is the "X Axis" of A2.

       Center : Pnt from gp) returns MakeHyperbola;
    ---Purpose: Constructs a hyperbola 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;
