Detailed Description

Efficient batch evaluator for parabola grid points.

Uses analytical formula: P(u) = Center + (u^2 / (4*Focal)) * XDir + u * YDir

Usage:

GeomGridEval_Parabola anEvaluator(myGeomParabola);
NCollection_Array1<gp_Pnt> aGrid = anEvaluator.EvaluateGrid(myParams);

(

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_Parabola::EvaluateGridD2

(

const NCollection_Array1< double > &

theParams

)

const

Evaluate all grid points with first and second derivatives.

Parameters

theParams

array of parameter values
