Detailed Description

Optimized batch evaluator for revolution surface grid points.

Evaluates the revolution surface formula: S(u, v) = Rotation(u, Axis) * C(v)

Where:

• C(v) is the meridian (basis curve)
• u is the rotation angle around the axis
• Axis is the axis of revolution

Optimization: Uses GeomGridEval_Curve for batch evaluation of the basis curve, then applies rotation transformations. Precomputes sin/cos values for each U parameter.

Mathematical formulas for derivatives:

• D1U = Axis Cross (P - AxisLocation), then rotated
• D1V = C'(v), rotated
• D2U = (Axis Dot (P - AxisLocation)) * Axis - (P - AxisLocation), then rotated
• D2UV = Axis Cross C'(v), then rotated
• D2V = C''(v), rotated

Usage:

GeomGridEval_SurfaceOfRevolution anEvaluator(myRevolutionSurface);
NCollection_Array2<gp_Pnt> aGrid = anEvaluator.EvaluateGrid(myUParams, myVParams);
