Btw how can we tell when anti-aliasing is perfect? I see aliasing effects too in real-life. For example when you walk towards a baseball field from a distance with 2 chain link fences overlapping at opposite sides of the field, you see all kinds of moire patterns and stairstepping patterns going on. Editting all that out doesn't represent reality truthfully.

The lattest,though, is not a sampling artifact. It's down to earth physical interference... We will need ray-tracing for that, before we worry about removing it. Nice use of GPU resources.

True, but do we really need ray-tracing for that? It should already occur with transparent textures or rendering power lines for example. fxaa is pretty destructive in those situations.

I'm looking forward to ray-tracing, anti-aliasing won't be a problem for now. Current hardware is far from powerful enough to render a real time high-res noise free image. Realistic lighting still eludes the best cgi in movies. I recently watched Samsara and Life of Pi. CGI still can't compete with 70mm film.
