toBSpline()

GeomBSplineCurve* Geom::GeomCurve::toBSpline	(	double	first,

	)		const

toBSpline Converts the curve to a B-spline

Parameters

This	is the start parameter of the curve
This	is the end parameter of the curve

Returns

a B-spline curve

toNurbs()

virtual GeomBSplineCurve* Geom::GeomCurve::toNurbs ( double  first, double  last  ) const

virtual

The default implementation does the same as toBSpline. In sub-classes this can be reimplemented to create a real NURBS curve and not just an approximation.

Reimplemented in Geom::GeomArcOfParabola, Geom::GeomParabola, Geom::GeomArcOfHyperbola, Geom::GeomHyperbola, Geom::GeomArcOfEllipse, Geom::GeomEllipse, Geom::GeomArcOfCircle, and Geom::GeomCircle.

toShape()

TopoDS_Shape Geom::GeomCurve::toShape ( ) const

virtual

Implements Geom::Geometry.
