Via an interesting post from Eric Haines with some cool tidbits. The whole siggraph 2015 proceedings is free this week.
Also Eric notes: Folklore 1: Jim Blinn confirmed that the teapot model was shrunk down
because it looked nicer that way, not that the pixels were non-square
(incorrectly propagated here and here). Jim & 3D printed teapot. (I have also spread that false info! We will know computer graphics has gone mainstream when this is at snopes).
