Detailed Description

Batch evaluator for offset curve grid points.

Evaluates the offset curve formula: P(u) = C(u) + Offset * (D1(u) ^ Direction) / |D1(u) ^ Direction|

Uses GeomGridEval_Curve for batch evaluation of the basis curve, then applies offset transformation.

Usage:

GeomGridEval_OffsetCurve anEvaluator(myGeomOffset);
NCollection_Array1<gp_Pnt> aGrid = anEvaluator.EvaluateGrid(myParams);

(

const NCollection_Array1< double > &

theParams

)

const

Evaluate all grid points with first and second derivatives.

Parameters

theParams

array of parameter values

Returns
