3-D Goes Glassless

In the wake of the successful 3-D on Imax release of The Polar Express, development of more realistic 3-D imaging techniques continues.

George Lucas viewed a 3-D clip of part of the original Star Wars movie, and declared “it looks better than the original.” How did this happen? New techniques now exist, allowing a studio to convert a typical single-camera shot movie to a 3-D movie. While this type of 3-D will continue to require the familiar red and blue lens glasses, later techniques will move away from needing them.

These techniques, developed by the likes of Japan’s Toshiba and others, use multiple screens to render 3-D imaging in front of the screens. The images display in layers, and looking through the layers provides the illusion of depth. Entertainment would be one use for this, but scientific and military uses will appear should the obstacles to development be overcome.

Limitations in the ability of modern TV screens and processing power of computers means we won’t see true holograms anytime soon. Technologists will have to find a way to get more lines of resolution out of video screens in an affordable way, and computers will have to increase in power dramatically in order to provide movement to those images.

Until then, we will have to live with those silly glasses.
