• Shading is an option for SurfaceGraphics that specifies whether the surfaces should be shaded.
• With Shading -> False, the surface will be white all over. So long as Mesh -> True, however, mesh lines will still be drawn.
• When Shading -> True, the actual shading used can either be determined by the height, or, when Lighting -> True, from simulated illumination.
