I Robot

I, Robot was the first commercially produced arcade video game rendered entirely with real-time, flat-shaded, 3D polygon graphics. Previous real-time 3D graphics were vector lines instead of rasterized polygons, one example being Atari's Tempest (1981) a "tube shooter" which Dave Theurer had also designed and programmed. While Funai's laserdisc game Interstellar (1983) had previously used pre-rendered 3D computer graphics and Simutrek's Cube Quest (1983) had used real-time 3D graphics combined with laserdisc full-motion video backgrounds, I, Robot was the first arcade game to be rendered entirely with 3D polygon graphics at runtime. It was also the first video game to feature camera-control options. The game's name was originally "Ice Castles", but was changed to "I, Robot".
