This only applies to the most common form of anti-aliasing, multisampling. There is also analytical anti-aliasing, which derives the pixel coverage directly from the equations of the shape (for vector graphics), see eg. the implementation in Skia [1], or for a classic, Wu's algorithm [2].

- msephton 3y agoThe first illustration app I used that offered anti-aliasing was Xara Studio, which ran on very modest Windows PC hardware in 1995. Originally it was called ArtWorks and ran on 8MHz Acorn Archimedes with 2MB RAMin 1992! I guess it used an anti-aliasing solution like this? http://www.cconcepts.co.uk/products/artworks.htm#:~:text=ArtWorks%20is%20an%20entirely%20new,to%20our%20other%20publishing%20products http://www.cconcepts.co.uk/products/artworks.htm#:~:text=Art....
