Detailed Description

This class implements the following algorithms used to create a 2d Hyperbola from gp.

• Create a 2d 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.
• Create a 2d Hyperbola from its major axis and its major radius and its minor radius.

^YAxis | FirstConjugateBranch | Other | Main ------------------— C ---------------------------—>XAxis Branch | Branch | | SecondConjugateBranch |

An axis placement (one axis) is associated with the hyperbola. This axis is the "XAxis" or major axis of the hyperbola. It is the symmetry axis of the main branch of hyperbola. The "YAxis" is normal to this axis and pass throught its location point. It is the minor axis.

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

Constructor & Destructor Documentation

gce_MakeHypr2d::gce_MakeHypr2d	(	const gp_Pnt2d &	S1,
		const gp_Pnt2d &	S2,
		const gp_Pnt2d &	Center
	)

Constructs a hyperbola centered on the point Center, where:

• the major axis of the hyperbola is defined by Center and point S1,
• the major radius is the distance between Center and S1, and
• the minor radius is the distance between point S2 and the major axis.

gce_MakeHypr2d::gce_MakeHypr2d	(	const gp_Ax2d &	MajorAxis,
		const Standard_Real	MajorRadius,
		const Standard_Real	MinorRadius,
		const Standard_Boolean	Sense
	)

Constructs a hyperbola with major and minor radii MajorRadius and MinorRadius, where:

• the center of the hyperbola is the origin of the axis MajorAxis, and
• the major axis is defined by MajorAxis if Sense is true, or the opposite axis to MajorAxis if Sense is false; or
• centered on the origin of the coordinate system A, with major and minor radii MajorRadius and MinorRadius, where its major axis is the "X Axis" of A (A is the local coordinate system of the hyperbola).

gce_MakeHypr2d::gce_MakeHypr2d	(	const gp_Ax22d &	A,
		const Standard_Real	MajorRadius,
		const Standard_Real	MinorRadius
	)

Creates a Hypr2d centered on the origin of the coordinate system A, with major and minor radii MajorRadius and MinorRadius, where its major axis is the "X Axis" of A (A is the local coordinate system of the hyperbola).
