I don't think so. There will still be visible artifacts due to the fact 
that pixels are square areas of color, even if each pixel is exactly the 
color of the area under it. In my raytracer, I made an antialiasing 
method that just made multiple passes over the image. After rendering 
overnight, enough passes that the difference between the pixel color and 
the "real" color was too small to represent on the monitor, there were 
still visible moire artifacts. Sampling each pixel with a spherical 
distribution instead of a flat square distribution helped some.
