class  Convert_EllipseToBSplineCurve
 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 . More...
