100 Million Pixels of Virtual Reality 190

Roland Piquepaille writes "It's ironic that Iowa State University (ISU) announced a big upgrade of its C6 virtual reality (VR) room the same day as SGI filed for bankruptcy. Back in 2000, this 10x10x10 foot room was powered by SGI Onyx2 computers. The new version of this six-sided VR room will use 96 graphics processing units from Hewlett-Packard. And with its 24 Sony digital projectors, the researchers at ISU will immerse themselves into images of about 100 million pixels in the most realistic VR room in the world. Of course, this upgrade is not cheap. But with this $4 million addition, this new C6 should lead to new advances in urban planning, genetics, engineering or unmanned aerial vehicles."

        Actually, the CAVE room is a room inside a much larger room. Some space is saved by using mirrors and such to fold the optical path of the projectors, but sometimes this isn't desireable, as mirrors cause light loss (some of the light is absorbed by the mirrors - mirrors aren't 100% reflective).

        If you're doing it on the cheap and only have three or four projectors, you don't need much of a cluster, just a three or four networked computers. Or, use two dualhead computers.

        You'll have a small amount of lag in the syncronization (network + OS + application software) but with some tweaking of the OS network configuration, or using some insanely fast system rather than a network (shared memory backplane?), you might get it to a few ms?

        If you want frame-by-frame synchronization you need some specialized equipment driving the projectors, stuff like this: http://www.es.com/products/image+generators/index. asp [es.com]

      There actually are things you can do in the C6 that you cannot do with goggles. For one - and to name something that I know is implementable and implemented - you can track body posturing and position within the C6 to make the experience more engaging/real. Any pictures just do not do this justice; the "seams" shown in the picture are not nearly as obvious in the real thing. On that note, I will say that I've nearly walked into the wall before (on the old system), and missed walking into the screen by a matter of about 6 inches.

      With respect to your other comment, the part about interoperability (The goggles would also have the benefit of being runnable on relatively standand class hardware), sometimes you want and need specialized solutions to do great things. Just because you or I cannot hope to afford such a system doesn't invalidate the system.

      There are no head-mounted displays that will deliver anything like the pixel resolution of a system like this. You simply wouldn't get the detail. And, the data infrastructure for this kind of project (where the aim is to visualize complex data) is not possible on "relatively standard class hardware". Another thing: In a cave environment like this, if you turn your head, the graphics view is updated only slightly or not at all. With a head-mount display, the whole scene has to swing round when you turn your head. If there's any latency in head-tracking (likely) or graphics rendering (possible), then the cave is much less unsettling per head-turn than is the head-mounted display. Less nausea. And another thing: you get a much larger peripheral view in a cave, leading to better understanding of context. Undisclaimer: I work for HP. :-)

        A head mounted display doesn't have to have that kind of pixel resolution. The input resolution to your brain is only about ~10 million elements in the eye, so with an up close goggle you can get away with something like 2-3 million pixels with no loss of detail. The head tracking issue is more relevant, though presumably you can again do better with a HUD because you can do fast inertial measurement at the head rather than having to use smart cameras to track. Then assuming you have an equal amount of processing power available to create the scene, the hardware required to render it to goggles will be much cheaper and more conventional.

    • Another post mentions tracking movement as a good reason for it you can't really use googles for, but I'll go one better.

      How about it's great for having more than one person in there and you can point at a spot and keep talking. With googles you'd both have to be wearing them and you'd have to describe to the other person the point you are looking at.

      At least that's what I thought of.

      • The trouble is that this kind of environment doesn't usually work for more than one person. Reason #1: The projections are calculated for the location of the head-tracked user's eyes. With the stereo goggles on, everything makes sense... for him or her only. Reason #2: A six-sided cave usually has back-projection on all surfaces, including the floor. A perspex floor supported only at the very edges is unlikely to take more than one or two person's weight.
        • #1 -
          Yes, though head-tracking is typically only done for 1 user, there are ways to set it up with multiple head-tracks and render/shutter multiple times per application-frame. Further, the difference between tracked/non-tracked users is really only an issue for objects that are near the 'screen' or would be 'inside' the walls. Large-scale or large-distance viewing is not affected since the binocular disparity is so small.

      Given that SGI powered the first version of C6, and that C6 is receiving a massive upgrade, it would be an "expected result" that SGI would benefit. However, the "actual result" is that they declared bankruptcy on the same day. It could be said that this is an "incongruity." So it is not unreasonable to say that this is indeed ironic.

    The most realistic virtual reality room in the world

    AMES, Iowa -- More than $4 million in equipment upgrades will shine 100 million pixels on Iowa State University's six-sided virtual reality room.

    (image)C6 battlespace

    (image caption)Jared Knutzon, an Iowa State University graduate student in human computer interaction, demonstrates how Iowa State's C6 virtual reality room can control the military's unmanned aerial vehicles.

    That's twice the number of pixels lighting up any virtual reality room in the world and 16 times the pixels now projected on Iowa State's C6, a 10-foot by 10-foot virtual reality room that surrounds users with computer-generated 3-D images. That means the C6 will produce virtual reality at the world's highest resolution.

    Iowa State's C6 opened in June 2000 as the country's first six-sided virtual reality room designed to immerse users in images and sound. The graphics and projection technology that made such immersion possible hasn't been updated since the C6 opened.

    The difference between the equipment currently in the C6 and the updated technology to be installed this summer, "is like putting on your glasses in the morning," said James Oliver, the director of Iowa State's Virtual Reality Applications Center and a professor of mechanical engineering.

    The new equipment -- a Hewlett-Packard computer featuring 96 graphics processing units, 24 Sony digital projectors, an eight-channel audio system and ultrasonic motion tracking technology -- will be installed by Fakespace Systems Inc. of Marshalltown. The project is supported by a U.S. Department of Defense appropriation through the Air Force Office of Scientific Research.

    The project began this spring with a prototype upgrade to one wall of the C6. The remainder of the work will continue throughout the summer. Oliver said the improved C6 will open in the fall. A grand opening celebration is being planned for the spring of 2007.

    A better C6 will be good news for the Iowa State researchers who study virtual reality.

    Chiu-Shui Chan, an Iowa State professor of architecture, has used the C6 to develop 3-D models of buildings, cities and workplaces. He's studying how virtual reality can be a tool to create a library of historical buildings, plan urban growth and test workplace efficiency.

    (image)virtual Beijing

    (image caption) A virtual model of the Xidan business district in Beijing can help city planners manage urban growth.

    Chan said the upgrade will improve the visual realism and interactive speed of his virtual reality applications. And that will enhance the sense of place in his applications and the effectiveness of his research.

    Chan said the C6's existing technology requires him to balance and sacrifice some of a project's size, speed, realism or human-computer interaction. "With the new system I won't have to worry about that," he said.

    Eve Wurtele, an Iowa State professor of genetics, development and cell biology, working with Julie Dickerson, an Iowa State associate professor of electrical and computer engineering, has used the C6 to develop new ways to visualize data from as many as 22,000 genes. She's also developing a virtual cell project that shows cells in 3-D action to help students learn about photosynthesis and other aspects of cell biology.

    Wurtele said the higher speeds and better pictures will be a boost for her research and teaching.

    "This upgrade is fantastic for us," she said. "It's essential for our research."

    Poor old SGI. They built amazingly excellent hardware, bleeding edge software, paid their workers well, treated employees like kings and customers like emporers, and donated heavily to the open source movement.
    So, of course they went bankrupt.
    Done in by the Microslop-ization of technology.
    We who were once the high preists of the cult of technology, wizards of electronic wonder, have become the janitors of the Microsoft plumbing, fit only to plunge out the cr@p that clogs the email pipes.
    By allowing slackers in our ranks to use shrink-wrap scumware to badly execute business functions cheaply, we have fallen from grace.

      SGI did a lot of things like you mentioned well, but treating their customers well - was a mixed bag in my opinion. Support was top-notch, just at about NetApp levels.

      Let's talk about sales.

      SGI Salespeople seemed to be constructed primarily out of ex-Porn producers replete with coke spoons around thei

      • I had to program on an Onyx4. I'll light that candle when they send me a check for all my wasted time trying to get fucking Mips to compile C++ standard compliant code.
      • I think what you observed was part of the death-spiral.

        A shrinking customer based caused SGI to "eat its own children" so to speak. They raised prices on parts and support to try to squeeze more revenue out of existing customers, which only caused them to have fewer existing customers.

        That was, as you have observed, mostly the fault of cocaine-snorting marketing types.

        After all, if you don't admit that negative things are happening, you can keep ignoring them until disaster strikes.
  • I'll take that bet and raise you 104,800,000 pixels.

  • 100M pixels on a 10' cube means 100000000 / (120 * 120 * 6) = 1157 pixels:inch^2, or 34dpi. Typical screen resolution is 72dpi, so this "VR" is less than 1/4 the resolution we're used to. Though viewing from approximately 5' distance in the room, rather than 2' on a PC, compensates quite a lot. OTOH, at least half those pixels aren't seen by a single viewer (behind them), and most of the rest are seen only outside the hi-rez foveas in the middle of their eyes' view field.

    I'd be more impressed with a 10' cub
