20140627 - CG Anti-Aliasing in 1984
Here is a, possibly resampled, video from the animated short "The Adventures of André and Wally B." made in 1984 by what was then named The Graphics Group.
Hard to find great info on this, seems like maybe 512x488 resolution rendered at around hour/frame on a 800 Mflop/s Cray. That would be around 2.9 Tflop used per frame.
