View-Dependent Stereoscopic Projection

Posted by timothy on from the say-that-9-times-quickly dept.

obiquity writes "The Augmented Reality lab is at it again with an extension of their 'smart projector' methods. In 'Enabling View-Dependent Stereoscopic Projection in Real Environments' they demonstrate a method for point-of-view dependent 3-D image projection onto almost any surface using multiple projectors for VR/AR applications. There are still several problems that need to be solved, but how far off is this technology from a holodeck type implementation?"

    You can do the "gas only glows at intersection of two beams" thing by using a two-photon upconversion process. For example, certain molecules can absorb 2 IR photons and emit 1 visible one. That's easier said than done under the best of circumstances, and may be impossible in a gas.

    It's been done in a glass by these people.
