All sources seem to indicate that the first practical solutions to anti-aliasing were invented Frank Crow, computer graphics pioneer (who incidentally works for nVIDIA these days), in 1977.  Earliest reference I could find was: The Aliasing Problem in Computer-Generated Shaded Images, Communications of the ACM, vol. 20(11), pp 799-805. Nov. 1997.  Of course I've also seen mentions of work done at the Architecture Machine Group at MIT in 1972, but I have not seen any references to published papers.  23:06 Jan 24, 2003 (UTC)
