Hi all, Thanks again for your answers, I've read about Multi-sampling, SMOOTH rendering and centroid variables. It all helped a lot.
I've few questions regarding these issues that were not clear: With multisampling: - if none of the samples falls within the intersection of the object and the pixel, than nothing will be rendered? Does it mean that tiny objects will disappear? - multi-sampling can never be accurate, right? I mean almost never can set the object alpha to the object pixel coverage percentange? With SMOOTH rendering: - is it more accurate than multisampling? Is it possible that OpenGL implementation will not calculate the pixel coverage correctly? - Does it works slower or faster than multisampling? - Will it work even for tiny objects? Thanks, Guy.
