3D video, a long time coming

It seems the world of consumer electronics is finally settling on a standard for 3D video, using active shutter glasses.

This isn't exactly a new approach to 3D. The Atari ST computer had the capability to make use of dual video output buffers, which it could switch between during the vertical blanking interval, enabling it to alternately display two different images. It also had a cartridge port that must have included the VBLANK signal, since at least one brand of LC shutter glasses was made available for use with the machine.

A 1986 article describes a similar system for use in flight simulators.

While I did own an Atari ST, I never tried the 3D glasses, so I can't speak from personal experience. My impression based on second-hand information was that it worked but the quality was not so good. Brighter screens with faster pixels and higher refresh rates, combined with better capture and generation of 3D video should make for a far better experience for today's viewers.

I'll probably get around to trying it our for myself this time.

Consumer Electronics
is becoming popular now-a-days. 3D glasses are the indispensable device when watching 3D TVs, 3D movies and 3D videos. 3D glasses provide the eyes of the viewer with two different images that represent two perspectives of the same object so that the brain will receive a depth perception. This is the basic principle of 3D glasses.
