Detailed Description

Implements construction algorithms for an arc of ellipse in 3D space. The result is a Geom_TrimmedCurve curve. A MakeArcOfEllipse object provides a framework for:

• defining the construction of the arc of ellipse,
• implementing the construction algorithm, and
• consulting the results. In particular, the Value function returns the constructed arc of ellipse.

Constructor & Destructor Documentation

GC_MakeArcOfEllipse() [1/3]

GC_MakeArcOfEllipse::GC_MakeArcOfEllipse	(	const gp_Elips &	Elips,
		const Standard_Real	Alpha1,
		const Standard_Real	Alpha2,
		const Standard_Boolean	Sense
	)

Constructs an arc of Ellipse (TrimmedCurve from Geom) from a Ellipse between two parameters Alpha1 and Alpha2.

GC_MakeArcOfEllipse() [2/3]

GC_MakeArcOfEllipse::GC_MakeArcOfEllipse	(	const gp_Elips &	Elips,
		const gp_Pnt &	P,
		const Standard_Real	Alpha,
		const Standard_Boolean	Sense
	)

Constructs an arc of Ellipse (TrimmedCurve from Geom) from a Ellipse between point.

and the angle Alpha given in radians.

GC_MakeArcOfEllipse() [3/3]

GC_MakeArcOfEllipse::GC_MakeArcOfEllipse	(	const gp_Elips &	Elips,
		const gp_Pnt &	P1,
		const gp_Pnt &	P2,
		const Standard_Boolean	Sense
	)

Constructs an arc of Ellipse (TrimmedCurve from Geom) from a Ellipse between two points P1 and P2. The orientation of the arc of ellipse is:

• the sense of Elips if Sense is true, or
• the opposite sense if Sense is false. Notes:
• Alpha1, Alpha2 and Alpha are angle values, given in radians.
• IsDone always returns true.
