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.
