This along with your other partisan Nvidia politics you posted in this thread is wholly inaccurate and usually off topic to the subject in which you've replied to. Which most of the time is used to campaign for nvidia.
Real time rendering of ray tracing goes all the way back to the late 1970s and guess what it was used on...a computer.
Ray Tracing has been around for the last 40 something years. It doesn't require a GPU and it's not particular for an API. All of whichyou will ignore for some random googled search topic in an attempt to continue your logical fallacies.
This is another prime example of your partisan posting for nvidia which is not actually true.
Real time RT was not possible in 1979. Non-real time RT rendering is old. That video shows how limited super computers were in 1979's when rendering with simple shapes. That video was created an engineer at bell labs.
The idea of ray tracing comes from as early as the 16th century when it was described by Albrecht Dürer, who is credited for its invention.
RT real tracing is a completely different subject as you fully well know. That video is well known. Getting RT to run on home PC's in real time is not an easy tasks. It has only been prossible starting with the 20 series of cards from nvidia. Trying to state this is partisan that NVidia spent 10 years researching how to get RT to work on home PC's in RT is pure non sense. One would have to request you stop playing silly little games trying to smear me.
