And here I was expecting you to talk about Fourier transforms. Ah well, maybe next time.

But we're talking anti aliasing on videogame graphics, not anti aliasing on a mathematical way. I don't think that this forum is the best place to talk about the Shannon theorem or signal reconstruction.

..it's done using the same method. How do you think they code it? "Please blur this pixel? Cheers buddy!" =p  

I know, I know, but as haxxiy says, I'm sure that 99% of the people here doesn't know what a FFT is, so it's not the way to try to explain it. "intelligent blur" AA isn't really AA, it's not a mathematically correct way to do AA, but it's a good enough substitute. Real AA as MSAA or SSAA do it the "correct" way, taking more samples to try to correct the undersampling.
