Hi otaku, I'm not sure but I think it was in the begining of the 80's, as I recall from the "The History of 3D Graphics Evening" at the 3D Festival... but I'm not sure... I also think they said the first movie which there really was used CG in was TRON... here are some links... https://www.asterius.com/atari/index "A Brief, Early History of Computer Graphics in Film"... --> https://www.beanblossom.in.us/larryy/cgi.html some Pixar history... --> https://www.pixar.com/companyinfo/history/index.html "An Historical Timeline of Computer Graphics and Animation"... --> https://www.accad.ohio-state.edu/~way.../timeline.html this site also got some info... --> https://www.geocities.com/CollegePark/5323/ITGSmain.htm good luck with it... regards Strarup
