this is definitely a render but Hughes Research Labs in Malibu had a room like this in the early 90s, they called it the Cave, using projectors synced up to several computers. meant for one user at a time.
Disneyland Anaheim had a giant room circled by projectors in the 1980s where visitors would stand while holding a handrail and they showed river rafting videos that weren’t as crazy as this.
VR caves are still a thing. It’s also the technique used for virtual production, with the backgrounds rendered in realtime in Unreal Engine, trackers on the camera for positional data, or camera on a robot arm which negates the need for trackers. It’s very cool tech that opens up a lot of possibilities that would be prohibitively expensive to shoot for real.
