Convert_EllipseToBSplineCurve Class Reference

This algorithm converts a ellipse into a rational B-spline curve.
The ellipse is represented an Elips2d from package gp with
the parametrization :
P (U) =
Loc + (MajorRadius * Cos(U) * Xdir + MinorRadius * Sin(U) * Ydir)
where Loc is the center of the ellipse, Xdir and Ydir are the
normalized directions of the local cartesian coordinate system of
the ellipse. The parametrization range is U [0, 2PI].
KeyWords :
Convert, Ellipse, BSplineCurve, 2D .

	Convert_EllipseToBSplineCurve (const gp_Elips2d &E, const Convert_ParameterisationType Parameterisation=Convert_TgtThetaOver2)
	The equivalent B-spline curve has the same orientation as the ellipse E.
	Convert_EllipseToBSplineCurve (const gp_Elips2d &E, const Standard_Real U1, const Standard_Real U2, const Convert_ParameterisationType Parameterisation=Convert_TgtThetaOver2)
	The ellipse E is limited between the parametric values U1, U2. The equivalent B-spline curve is oriented from U1 to U2 and has the same orientation as E. Raised if U1 = U2 or U1 = U2 + 2.0 * Pi
