◆ toBSpline()

GeomBSplineCurve * GeomCurve::toBSpline ( double  first,

toBSpline Converts the curve to a B-spline

Parameters
Thisis the start parameter of the curve
Thisis the end parameter of the curve
Returns
a B-spline curve

◆ toNurbs()

GeomBSplineCurve * 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 Part::GeomArcOfParabola, Part::GeomParabola, Part::GeomArcOfHyperbola, Part::GeomHyperbola, Part::GeomArcOfEllipse, Part::GeomEllipse, Part::GeomArcOfCircle, and Part::GeomCircle.

◆ toShape()

TopoDS_Shape GeomCurve::toShape ( ) const
