is the visibility of a Polygon exposed?
Hello Mathematica UG: Is it possible for my code to tell if a Polygon (in my graphics object) is visible? I assume that this is based upon (or is affected by) the ViewPoint-> setting. Further, I assume that the kernel is deriving this somewhere to do rendering. Do I have any access to this? If I evaluate: q = PolyhedronData["SnubCube"] I can see the component Polygon and GraphicsComplex objects that make up the Graphics3D. I want to make a code decision based on whether a face is showing. TIA. Regards..Roger W.
