Thread: What is 3D technology?

3-D technology refers to three dimensional technology that is used in films and motion pictures that provides some kind of illusion of depth perception and viewers enjoy some different kind of experience to this technology! The latest release of such a technology has been in the picture called ‘Avatar.’ The movie was shot with special motion camera to record the images. The technology is derived from stereoscopic photography /technology. Special projection hardware and eyewear are required to enjoy 3-D technology of the movies.

The 3-D films have been there since 1950s but they have found prominence during the end decade of the last century and first years of 21st century. But 3-D technology has now experienced a world-wide resurgence and is coinciding with the computer generated imagery and introduction of high definition video standards. Today the technology has also found space in Televisions. Now it seems that soon we are going to wear the specs or eyewear to enjoy television programs with the 3-D technology already input in the TVs. RealD Cinema is the world’s most patent and highly used technology for showing 3D movies in theatres and they are very cheap to install.

But the TV industry is trying to portray the fact that one won’t need the typical specs for watching the 3-D TVs. They are trying to revive the technology and make the 3D watching specs free affair though it has not been possible yet. Brands like Sony, Panasonic, Philips are promising excellent 3-D technology input in TVs. It is going to create a kind of 3D revolution where you would be able to experience the depth without the eyewear.

Normally to watch 3D movies we need circular polarized or active LCD shutter glasses. These are glasses that are used in theatres by public to enjoy the 3D images or pictures. The present day glasses or spectacles use circular polarized or active LCD shutter that ensure that each eye has different image and have different feelings that altogether create the impact on the brain.

I hate the current fad - every movie is being made in 3D. It is a painful experience - at least to a person who wears glasses like me.

I will wait for the day when I can watch real 3D without glasses. Alas, this seems to be a far off utopian dream today.

I saw 3D television at Coimbatore airport, you can get 3D experience without any glasses.

Which TV was that? And what was it showing? I am genuinely interested.

Around 2 years ago I went to coimbatore, that time i saw the 3d tv, i can't remember now the make of the tv, but some advertising were running on it. It was 3d but clarity wasn't that much good as is now. there were lines on the picture, like lenticular. Technology is changing every day, may be we can get better quality version of it today.

I asked because I haven't seen a 3D TV which does not require glasses.

The Nintendo 3DS has 3D tech that does not require glasses but there are several limitations:
a) the size of LCD is very small and that kind of 3D LCD panel is very expensive
b) the 3D effect is restricted to depth, i.e., the 3rd dimension shows depth inside the panel but not outside it - objects don't come protruding outside the panel
