IBM Develops New 3D TV Technology

neutron_p writes "IBM has recently announced a new and affordable 3D video system that works with normal DLP (Digital Light Processing) televisions. IBM demonstrated the new system on a 50-inch, flat-screen Texas Instruments rear-projection digital television at the 22nd annual Flat Information Displays conference held in San Francisco this month. This "black box" device can be connected to any DLP projector or television via the common VESA 3 pin stereo connector. Exact details concerning the 3D technology - still unnamed - were not forthcoming, but the company spokesperson said it was compatible with OpenGL and Direct Draw, which is definitely aimed at software developers who make 3D games."

Some prior research work in the area

At my last job at SEGA, my lab was in charge of coming up with many different and pioneering ideas for new ways to play video games, many of which, for one reason or another, never made it to market.

One of those was HOLO-GENESIS. It was a 3-D laser holographic projection device for the MegaDrive/geneis. It could have displayed 3-D rendered images, in full-color, in real-time, using a system of 3 red/green/blue lasers, and a finely-meshed micro-faceted surface which gave a pseudo 3-D effect based on carefully utilized light diffraction effects, a la printed holograms.

It was slated to come out in mid-1995, but at the time, we couldn't get a acceptable frame rate (3-D graphics accelerator hardware was still very primitive and expensive, the province of SGI workstations and arcade machines), so we decided to not commercialize it at the time.

In any case, I must say, this is a very interesting announcement, and I must congratulate IBM for further and seemingly admirable work on bringing such technology to the market. Hopefully they can continue to lower the price point and make it adopted wider.
