	Evaluate Nth derivative at all grid points. Hyperbola has cyclic derivatives with period 2: D1 = MajR * sinh(u) * X + MinR * cosh(u) * Y D2 = MajR * cosh(u) * X + MinR * sinh(u) * Y = D0 D3 = D1, D4 = D0, etc.

Detailed Description

Efficient batch evaluator for hyperbola grid points.

Uses analytical formula: P(u) = Center + MajorRadius * cosh(u) * XDir + MinorRadius * sinh(u) * YDir

Usage:

GeomGridEval_Hyperbola anEvaluator(myGeomHyperbola);
NCollection_Array1<gp_Pnt> aGrid = anEvaluator.EvaluateGrid(myParams);

Member Function Documentation

EvaluateGrid()

NCollection_Array1< gp_Pnt > GeomGridEval_Hyperbola::EvaluateGrid

(

const NCollection_Array1< double > &

theParams

)

const

Evaluate all grid points.

Parameters

theParams

array of parameter values

Returns

array of evaluated points (1-based indexing), or empty array if geometry is null or no parameters

EvaluateGridD1()

NCollection_Array1< GeomGridEval::CurveD1 > GeomGridEval_Hyperbola::EvaluateGridD1

(

const NCollection_Array1< double > &

theParams

)

const

Evaluate all grid points with first derivative.

Parameters

theParams

array of parameter values

Returns

array of CurveD1 (1-based indexing)

EvaluateGridD2()

NCollection_Array1< GeomGridEval::CurveD2 > GeomGridEval_Hyperbola::EvaluateGridD2

(

const NCollection_Array1< double > &

theParams

)

const

Evaluate all grid points with first and second derivatives.

Parameters

theParams

array of parameter values

Returns

array of CurveD2 (1-based indexing)

EvaluateGridD3()
