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.
Create(S1,S2 : Pnt from gp;
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;
