Hi, I have a related question, it seems that if you wanted to show the 'back face' of some polygons, you have too options, reverse the winding of your polygon definitions (which may involve recreating/indexing you geometry) or you could use PolygonAttributes.CULL_FRONT.
My question is, is there any performance hit when you specify CULL_FRONT instead of the default CULL_BACK. Related to this, do you get a major performance hit by specifying CULL_NONE?
