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() [1/2]

GeomConvert_ApproxCurve::GeomConvert_ApproxCurve	(	const occ::handle< Geom_Curve > &	Curve,
		const double	Tol3d,
		const GeomAbs_Shape	Order,
		const int	MaxSegments,

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.
