Shading
Shading is an option for Graphics3D, SurfaceGraphics and funtions that return Graphics3D or SurfaceGraphics. The default setting is (Shading→True) in which case polygons are colored as determined by simulated Lighting or the ColorFunction. The HiddenSurface option is used to render the surface as a transparent mesh.
