Constructor & Destructor Documentation

◆ AdvApprox_ApproxAFunction() [1/2]

AdvApprox_ApproxAFunction::AdvApprox_ApproxAFunction ( const Standard_Integer  Num1DSS,
const Standard_Integer  Num2DSS,
const Standard_Integer  Num3DSS,
const Handle< TColStd_HArray1OfReal > &  OneDTol,

const Standard_Real  First,
const Standard_Real  Last,
const GeomAbs_Shape  Continuity,
const Standard_Integer  MaxDeg,
const Standard_Integer  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.
