Detailed Description

A framework to convert a 2D curve to a BSpline. This is done by approximation within a given tolerance.

Constructor & Destructor Documentation

Geom2dConvert_ApproxCurve() [1/2]

Geom2dConvert_ApproxCurve::Geom2dConvert_ApproxCurve	(	const Handle< Geom2d_Curve > &	Curve,
		const Standard_Real	Tol2d,
		const GeomAbs_Shape	Order,
		const Standard_Integer	MaxSegments,
		const Standard_Integer	MaxDegree
	)

Constructs an approximation framework defined by.

• the 2D conic Curve
• the tolerance value Tol2d
• the degree of continuity Order
• the maximum number of segments allowed MaxSegments
• the highest degree MaxDegree which the polynomial defining the BSpline is allowed to have.
