I have after a few passes a screen consisting of shades of gray. Each pixel has an rgba color of k, k, k, k. Now, I want to draw on the screen another texture, but only on the parts of the screen of color (1, 1, 1, 1), and not on the rest. Is there any way to do this in (preferably unextended) openGL? Thanks
