Seeing as how we've reached another milestone 100 pages I think it's best to talk about another historic animation milestone. Cgi effects. Love em or hate them they've come a long way since the days when computers rendering of images was so limited it could only render wire frames in black and white. The first cgi images like the first animated images themselves are difficult to pin down. Computer renders have been found as far back as the early 60s such as this 3d model of an AT&t communication satellite I'm orbit dating from 1963. Just 6 years after sputnik became the first object to be launched into orbit.
Other early uses of cgi are found all thorough the 60s such as the first talking cgi "character mr computer in 1968
but it's application in film didn't take off until Alfred hitchcocks North by northwest became what is belived to be the first film to use computers to digitally render titles as opposed to painted title cards or painted frames. From there the early 70s saw attempts to design people in cgi...the results were well theres a reason it's called the uncanny valley.
Cgi animation really took off in the 80s albeit in small quantities. While pixar would love to stroke their ego amd claim Andre and wally b (1984) was the first full cgi animated short film that honor technically belongs to a 1982 French short film dream flight.
See you in another 100 pages.
