Detailed Description

Batch evaluator for offset surface grid points.

Evaluates the offset surface formula: P(u,v) = S(u,v) + Offset * Normal(u,v)

Uses GeomGridEval_Surface for batch evaluation of the basis surface, then applies offset transformation.

Usage:

GeomGridEval_OffsetSurface anEvaluator(myGeomOffset);
NCollection_Array2<gp_Pnt> aGrid = anEvaluator.EvaluateGrid(myUParams, myVParams);
