Constructor & Destructor Documentation

◆ AdvApprox_ApproxAFunction() [1/2]

AdvApprox_ApproxAFunction::AdvApprox_ApproxAFunction	(	const int	Num1DSS,
		const int	Num2DSS,
		const int	Num3DSS,
		const occ::handle< NCollection_HArray1< double > > &	OneDTol,
		const occ::handle< NCollection_HArray1< double > > &	TwoDTol,

		const double	First,
		const double	Last,
		const GeomAbs_Shape	Continuity,
		const int	MaxDeg,
		const int	MaxSeg,
		const AdvApprox_EvaluatorFunction &	Func )

Constructs approximator tool.

Warning: the Func should be valid reference to object of type inherited from class EvaluatorFunction from Approx with life time longer than that of the approximator tool;

the result should be formatted in the following way : <–Num1DSS--> <–2 * Num2DSS--> <–3 * Num3DSS--> R[0] .... R[Num1DSS]..... R[Dimension-1]

the order in which each Subspace appears should be consistent with the tolerances given in the create function and the results will be given in that order as well that is : Curve2d(n) will correspond to the nth entry described by Num2DSS, Curve(n) will correspond to the nth entry described by Num3DSS The same type of schema applies to the Poles1d, Poles2d and Poles.
