REYES renderers had a pretty nifty solution for shape antialiasing with their slicing and dicing of geometry into sub-pixel sized primitives. That was in the 80s, just for reference. Unfortunately, this method has a pretty complex implementation and just doesn't play all that well with hardware rasterization or path tracing and has since fallen out of favor.
