Detailed Description

Efficient batch evaluator for cone grid points.

Uses analytical formula: P(u,v) = Location + (RefRadius + v * sin(SemiAngle)) * (cos(u) * XDir + sin(u) * YDir) + v * cos(SemiAngle) * ZDir

Where U is angle (0 to 2*PI) and V is linear parameter along the ruling.

Usage:

GeomGridEval_Cone anEvaluator(myGeomCone);
NCollection_Array2<gp_Pnt> aGrid = anEvaluator.EvaluateGrid(myUParams, myVParams);
