Can I know the number of polygons that are actually rendered by OpenGL?
For example, If I try to render 100 polygons and 10 polygons of them are clipped by view frustrum culling, then the number of polygons that are actually rendered by OpenGL is 90. Is this right? Then How can I know the number of actually rendered polygons?
