Detailed Description

Batch evaluator for 2D offset curve grid points.

Evaluates the 2D offset curve formula: P(u) = C(u) + Offset * N / ||N|| where N = (D1.Y, -D1.X) is the normal (tangent rotated 90 degrees).

Uses Geom2dGridEval_Curve for batch evaluation of the basis curve, then applies offset transformation.

Usage:

Geom2dGridEval_OffsetCurve anEvaluator(myGeom2dOffset);
NCollection_Array1<gp_Pnt2d> aGrid = anEvaluator.EvaluateGrid(myParams);

(

const NCollection_Array1< double > &

theParams

)

const

Evaluate all grid points with first derivative.

Parameters

theParams

array of parameter values

Returns

(

const NCollection_Array1< double > &

theParams

)

const

Evaluate all grid points with first and second derivatives.

Parameters

theParams

array of parameter values

Returns
