3D Virtualization Edges Toward the Mainstream

Roland Piquepaille writes "With recent improvements in graphic cards and in powerful Linux-based PC clusters, virtual 3D prototypes are rapidly replacing actual physical prototypes in a wide range of industries, including early adopters such as aerospace or car companies. But now, software designers are also incorporating sound and tactile feedbacks to their Virtual Reality (VR) systems for real product development. In this long article, Desktop Engineering gives several examples of these new VR developments. But even if PC clusters and off-the-shelf graphic cards are cheap, a state-of-the-art VR facility such as an immersive CAVE can still cost more than one million dollars, because you need to build the viewing facility and buy expensive projection systems. However, costs are still decreasing and virtual prototyping is reaching the mainstream stage. This overview contains selected excepts and comments."

      Best bang-for-buck I've seen for home VR is a pair of shutter glasses. Basically the way it works if you have an LCD in front of each eye -- and in software the system renders a left eye image, and the glasses blank out your right eye -- then vice versa (syncing is handled by hooking the glasses inline between your monitor and your video card). I have the VR Visualizers from http://www.vrex.com/ ) and they're pretty cool.

      However: the DepthCharge plugin they have for viewing 3D content in a webpage Just Plain Sucks -- it doesn't keep state and remember what kind of glasses you have so you need to pick it again and again and again.

      The best-viewing mode with these glasses is interlaced (in addition to left/right image pairs, the dongle will blank our alternate scan lines on your monitor improving the effect a lot). Unfortunately on my glasses this mode requires you to hold-down a button on the glasses-controller, so it sucks for gaming without duct tape.

      Video cards and drivers that will put out stereo image-pairs are few and far between. Make sure your card will, or buy a card that will if you want to do any gaming. Game compatability is also an issue. Google will help here.

      Eyestrain. 'nuff said.

      It needs to be done in a completely dark room -- any light reflecting off of your monitor will tend to ruin the illusion of 3d.

      Your screen needs to be resonably flat -- curved monitors distort the 3d image ruining the illusion.

      A friend of mine has shutter glasses, and they really didn't do much for me when I tried them. The constant flickering - remember, you now only have half the refresh rate - gave me a headache, and the sense of depth was very weak.

      I suggest that before buying shutter glasses, one should check these things. I know I'm very sensitive to flickering, anything below 85Hz is useless to me. In "real-world" seeing I don't work off the stereoscopic vision for depth perception, I expect that this causes the weak improvement. (You can test this easily by closing one eye for an extended period of time. Some people start "grabbing air", while others just carry on as normal)

      phil,

      Very valid points, all of them. It sucks that they didn't work for you, but for me -- the "did it" after a fair amount of tweaking. The pitch-black room was the thing that helped the most for me -- that reduced the sensation of flickering and increased the depth and rise a lot. I actually wish my glasses were full goggles because I think most of the flicker I experience now is because even when my eye is "blacked" I'm still seeing ambient light from the monitor.

      Tweaking the refresh rate was very important in my experiments with these too -- the LCDs on the glasses do take time to change state so it's important to find the fastest rate that the glasses can sustain.

      Question -- did the glasses you played with support the "blanking-every-other-scanline" feature? I was utterly unimpressed with mine until I found that sweetness.

      And a note to everyone else: it seems that the site I mentioned has stopped selling in individual units. Although this is a sadness there are other companies.

  34. VR good for games, bad for business.... by MosesJones · · Score: 2, Informative


    I worked in an industry that used VR, you can probably guess which one if I say its not for entertainment. What we found was that for simulation elements and "gaming" it worked well, but for command and control type functions it was too much information to process and a flat 2D model worked better, the 3D model lead to things being missed as they were out of scope and also on periferal vision elements being given too much weight over the central image (the human eye reacts better to movement at the edges, its where the tigers are coming from).

    So great that its getting cheaper, but please god can all those "cool a VR desktop" people just have a think for a second. Maybe zoom out (ala the Mac and Looking Glass) to get your windows, or rotate (looking glass) but a full VR would be dreadful, we found users getting lost and disoriented as they tried to navigate unstructured information (and most people's directory structures are very unstructured).

  36. Early Adopter Outlook by Chitlenz · · Score: 2, Informative

    As the lead developer on a PACS system (this involves capture images for radiological diagnostics) we have been working to evolve a lot of these technologies and adapt them more towards desktop use. MRI in particular captures image data with volumetric depth and allows for relatively easy conversion to 3d volumetric models. Add some basic surface analysis and you get texture modelling of 3d surfaces in realtime, for instance Terarecon's Aquarius stations (http://www.terarecon.com) have the capability to use live data captured from a patient still in an MRI bore to allow the extraction of live models (as in watch your heart beat), and future versions will be able to 'live-simulate' heart attacks, etc. Terarecon is a competitor of ours, but their site has some cool examples =)

    For us, VR is an inevitablity, but CAVE environments are impractical. Today, we use high end (5MP) flat panels to lay out diagnostic workstations in something similar to the 'Minority Report' layout, minus the panel transparency. This guy (article author) is looking at VR applications essentially in researched industrial design, which is cool and all, but what's important to note is that in order for someone other than a labrat to be comfortable with the environment it has to become a lot more comfortable to the average guy. That is, VR needs to emulate life a lot better than it does today in its interfaces. Convincing a non-techie to put on ANYTHING (glove, helmet,etc.) ain't gonna happen for a workspace that will be used 12 hours a day by one person. The important thing missing still is ergonomics and practicality.

    The cool thing though, is that TRUE VR is very close to reality today, that is to say that we can very accurately (to the mm, soon to be to the micron) recreate a simulated space within you today, and use that data to effectively represent you on a computer. Its actually kinda creepy since when you texture a skull study it really looks like the person you scanned heh. I keep meaning to scan me and turn me into a Doom3 model (muahahaha).

    Anyway, good article, but not so relevant to the real world just yet IMHO. The best hope for entertainment VR is indeed still the CAVE systems. I dunno where they got 400k from, I can build a cave for around 20k, including everything. Maybe they included the cost of the building too or something.

  37. Lighting & Stage by Hobadee · · Score: 1

    Lighting designers have been doing this for some time as well. Programs such as Martin's Show Designer let the designer come up with the entire show on his/her home computer, saving enourmous amounts of money. When the show goes live, all the designer has to do is save a file and transfer it to the board and the show will look exactly as advertised! I also believe sound engineers are starting to use this technology as well to determine the acoustic properties of venues.

    Also, slashdot and other 'blog'-type sites say they want to be taken as serious journalists like newspapers. In which case, newspapers have 'advertisement' above adverts, especially ones which are of the same format as normal articles, so slashdot should do the same for stories like this. If you want to be considered the same as the professionals then act accordingly. Yes, this also goes for the picture-adverts above the comments.
