Realtime ray tracing shown by Adshir at Siggraph

  Ever since Arthur Appel proposed the core technology for ray tracing in his 1968 paper, realtime ray tracing has been the ultimate goal for computer graphics. The Ballistics Research Lab (BRL) demonstrated ray tracing for ballistics research using technology developed by the Mathematical Applications Group, Inc. (MAGI) in 1979. Turner Whitted showed how to speed up the calculations in 1980, and more recently Nvidia showed how to speed up de-noising with AI. Each step over the years, combined with steady improvements in processor performance, thanks to Moore’s Law, got us to realtime ray tracing on a PC in 2018
