Ray-tracing, the simulation of light rays and their interactions with the environment, is the holy grail of computer graphics and can achieve Hollywood-level imagery. The Amiga home computer, despite being capable of ray tracing in the 80s, was left out of the conversation due to hardware limitations. The Amiga played a significant role in visual effects and pioneered software that is still used in the TV and film industry today, but ultimately fell out of favor due to financial struggles and competition from home consoles.
Was the juggler really rendered? To me it looked like all the balls where just flat brushes with a 3D ball effect that is moved around always facing towards you. Similar to the enemies in duke nukem and doom.
