A few days ago I found a video on Twitter showing the Evans & Sutherland CT5 Flight Simulator system. It was labeled as 1981 footage and looked really amazing. The first time I saw similar 3D grahics in computer games was in the late 90s and in ealy 2000s. I wasn't suspisous because it was described as a product made for the military and I thought it's normal the technology to be more advanced.
Yesterday I showed the video to my colleagues, all of them experienced developers and computer gurus, and they said it's impossible such graphics to be achieved in the 80's. I tried to search for a proof but I found none except a short documentary on YouTube and some forum topics where people were discussing how it was achieved without mentioning anything about the exact year. I found no definitive proof that the year of creation of CT5 system was 1981. No product specifications, no publications in wellknown newspapers and not even a Wikipedia article. I'm amazed how little information is out there about something so astonishing. And this is one of the things that fuel the doubt of my colleagues.
Was Evans & Sutherland CT5 really created in 1981 or at least from the same decade?
My colleagues are with a high self esteem and it's hard to change their opinion on something. I'll appreciate any resource that proves or disproves the existance of such advanced graphics in the early 80s as well as some details how it was made.
In the link below you can see the two parts of the documentary I mentioned earlier and a short forum discussion about the CT5 and similar technologies. My colleagues don't consider it a sufficient proof.
