Detailed Description

A framework to convert a 3D curve to a 3D BSpline.
This is done by approximation to a BSpline curve within a given tolerance.

Constructor & Destructor Documentation

GeomConvert_ApproxCurve::GeomConvert_ApproxCurve	(	const Handle< Geom_Curve > &	Curve,
		const Standard_Real	Tol3d,
		const GeomAbs_Shape	Order,
		const Standard_Integer	MaxSegments,
		const Standard_Integer	MaxDegree
	)

Constructs a curve approximation framework defined by -

• the conic Curve,
  
• the tolerance value Tol3d,
  
• the degree of continuity Order,
  
• the maximum number of segments
  MaxSegments allowed in the resulting BSpline curve, and
  
• the highest degree MaxDeg which the
  polynomial defining the BSpline curve may have.
