Matrix-Like VR Coming in the Near Future?

Anonymongoose writes "A researcher at Brookhaven National Lab reckons it could be just a few years before computers can pass through the uncanny valley. The article refers to this as a 'Graphics Turing Test': 'a computer can be considered intelligent if it can create an artificial world capable of fooling a person into believing it is the real thing.' Michael McGuigan has been performing some interesting experiments using Brookhaven's Blue Gene/L supercomputer and has shown that it can produce realistic lighting effects in real time. McGuigan's original research paper (pdf) is available online."

  15. How about another shot at that headset VR?! by Sark666 · · Score: 4, Interesting

    I remember when I first heard of VR around 1989-90. I'm talking about the big headset with two screens one for each eye drawing a slightly different angle, with it also having head tracking and then draw the screens appropriately.

    I thought, what an amazing idea! This seemed like the closest thing you could have to a holodeck (kind of like a holodeck in reverse). Anyway, some games came out in the arcades. One company in particular was virtuality. They had this game called Dactyl Nightmare that I tried a couple of times. It was like a fps where you and a friend were pitted in an arena against each other with a gun. There was also this pterodactyl flying around that would randomly try and grab one of you. Anyway, neat simple idea to showcase VR. Problem was, it was certainly not ready for prime time.

    The screens were extremely low res. I mean it seemed lower than 320x240 per screen. But what really ruined the immersion factor was the frame rate. It felt like it was in the teens at best. Most of the time it felt like a slideshow.
    Anyway, they had a couple other games at the time, and they were pretty much the same experience.

    I still think it's a great idea, just way ahead of it's time. The problem was they were trying to do 3d (on two screens no less) in a 2d world. At that time, I think virtua racing/fighter just hit the scene. Almost all games were 2d still, and most certainly with the consoles/home computers.

    I checked their wiki entry just now and there was a sequel to dactyl nightmare which came out about 3 years later that ran on a 486, so I could just imagine what the first ran on.

    Anyway, the idea seemed to flop, but I always thought it was an idea ahead of it's time. Certainly we could do two screens at say 640 480 at 60 fps. It's been 16-17 years since I tried this and thought by now the idea would resurface.

    Its one thing to come up with a realistic model and scene for a photo-realistic still frame. Its another, to rig all of those models so that they can interact with each other in a pre-determined way. Its something altogether entirely different to do this in real time without predetermined paths and choreographed actions, and modelling all viewable elements based upon the degree of movement that a user has within the space.

    This is very much highlighted in the differences between high-poly count models (for detailed stills) and low-poly models (used for 3D games). The "art" for immersive environments like simulated 3D gaming (fps, racing sims etc) is to come up with a convincing representation of a real world object with the lowest poly count possible.
