I was watching a bit of the 2019 How to train your Dragon movie on TV tonight, and a scene that had waterfalls with lots of flowing water and mist, had me thinking... just 23 years ago, the Beast Wars cartoon doing water and waterfalls... as Mainframe (like Pixar) was one of the early pioneers of making CGI effects like water, landscapes and curves easier and cheaper to produce.
I remember how amazed us fans were when Beast Wars first started, at this "new" cartoon medium (many of us hadn't seen Reboot, so the Toy Story movie the year before was really the only previous show that was entirely done in CGI), as previous CGI by 1995 was still either very expensive limiting its usage to just special effects in movies, or still too simplistic, leading to programs like Toy Story in 1995 and Reboot in 1994.
Kids these days just won't understand, how much the CGI landscape has changed... just look at computer games - remember the Beast Wars computer game in 1996, which was supposed to be a real form of 3D animation. Now computer games and virtual reality games have evolved even more than CGI cartoons.
