Mixed-Reality 3D Volumetric Projector

Posted by timothy on from the that's-a-lot-of-projectors dept.

First time accepted submitter Gortu writes "We are describing and demonstrating a 3D Volumetric Projector (YouTube video); in short words: a device that enables mixed reality. The 3D projector has very poor quality, we just have 10 rotational voxels (as we are using only 10 regular LCD projectors), but is proof of concept for developing a commercial solution."

  3. A better way i dreamed up - with water guns by TheCouchPotatoFamine · · Score: 3, Interesting

    My best idea is to use a hundred pulsed water guns and a laser that can be precisely aimed on the fly. You emit downward-dropped, fast-moving squirts of water algorithmically timed so that when the drop reaches the "pixel" the laser also illuminates that spot, making a pixel appear in midair. If the guns are in a row, that's a 2D plane. You could do this with a 100x100 water guns to make a 3d system, where 2d is the box of water guns on the ceiling, and 3D is when the drop is illuminated.

    Make sense? I so want to do this!

    This approach by Sony shows much more promise in the short and medium term:

    No walking through the image, though.

      And only in one plane. Move up and down, and the image will distort rather than allow you to look down onto it or up under it. Not volumetric.

    Needs ... some way to maintain uniform fog distribution in a room.

    Or a way to measure the fog distribution in real time and adjust accordingly.

    Or a way to redundantly re-state the quoted post.

    What the hell is this?

    it's a pitch to try and score some funding.

    We need funding and are looking for people interested in participating in this. If you know someone, shoot!
