InFocus – DepthQ 3D Video Projector

April 20, 2005

depthqYears ago I remember seeing my first “3-D movie”. Oddly enough I can’t even remember it’s name, some sort of Treasure Hunt flick complete with all the hokey 3-D tricks that go into just such a movie. But what if 3-D moved beyond the red and blue paper glasses, into 10’ images with palpable depth perception, at a price point the masses could embrace?

While the DepthQ (co-developed by InFocus and Lightspeed Design Group) doesn’t promise quite that level of immersion or practicality, it could be a stepping stone to that end. The DepthQ projector requires active LCD shutter glasses, something that the typical home theater enthusiast wouldn’t likely tolerate, but it’s conceivable that years down the road a lens system, or multiple lens system could be adapted that would render the glasses unnecessary. One possible scenario for such a system could involve multiple lenses to render true 3-D, but likely only from a very limited viewing angle.

Currently, the DepthQ is best suited in laboratory or engineering environments where 3-D models, graphs or renderings need to be viewed in large scale. But hey, who knows what this technology could evolve into with the benefit of expanded research and development.

    hi , when i run DepthQ Player , I get a message “This Graph cannot view Properly” please suggest

  • Really interesting. Though not practical now, perhaps 3-D films will become a norm in the future.

  • The method described above will work even with LCD projector, but it will be necessary to add several other component: precise dual projector montage, special non-depolarizing screen, source of dual genlocked video signal, polarization filters + filter holders. The DepthQ InFocus
    is more elegant and portable solution.

  • There’s a pretty cool and straightforward method for displaying 3D using off the shelf equipment. It works basically like this…

    Stack two DLP projectors on top of each other (LCD will not work), then align them to overlap correctly. Take a sheet or lens of polarized material, and place it in front of the first projector lens. Next take an identical polarized gel, reverse it’s orientation to be opposite the first sheet, and place it over the second lens.

    If you then provide stereo video to the projector set (say two DV cams spaced properly apart), and slap on a pair of polarized glasses (matching the polarized lenses in front of your projectors), you should see a 3D image.

    The concept is pretty straight forward. Anyone know where to get polarized sheets of plastic?
