3D Technology In Our homes: How they Work
3D films have been out for quite some time, it has only been recently that technology has allowed us to bring the whole 3D experience to our homes. With a capable 3D entertainment system (3D glasses, 3DTV and a 3D capable player) we can enjoy great and exciting films in the comfort of our homes. Usually these movies or films are in the optimized blu-ray format, though it may be surprising to hear there are also a few select 3D DVD feature films available. It doesn’t stop there either, the development of some 3D television shows or video games has begun as well.
Here are some 3D Movies that are Available
It works on the same principles as your local movie theater. That said, the screen shows two separate images at the same time. Each picture is designed for either your left or right eyes. With the aid of 3D glasses the combined pictures will give the illusion of a third dimension or depth. This is made possible with the visual perception event called Stereopsis, human eyes are apart and can see different angles which the human brain puts together giving the three dimensional experience.
Most 3D TVs require the use of 3D glasses. The way they work is that the glasses shutter and block one of your eyes for a fraction of a second. This is done to separate the images meant for each eye. These glasses are in sync with the 3D player or TV, usually through a infrared or radio frequency connection. The lenses of the glasses are made out of liquid-crystal which turns dark when a minuscule amount of voltage is run through it. The glasses will shutter on and off at high speed, more than a hundred times per second. Also the glasses themselves are electronic in nature, containing a battery and other needed components. Without the special glasses, 3D features will be unwatchable and the pictures will often be confusing.
There’s another kind of 3D TV in development called ‘Autosteroscopy’, these television sets don’t require the use of 3D glasses at all. All major television companies like Samsung are developing different versions of them. While these TV’s may be the way of the future, It may take awhile for them to be readily available, since at present they can be extremely expensive.
The last thing that makes this work is the 3D player. The process is like any other player, where it reads the BD or the 3D DVD and sends the signals and information towards the television. Preferably you want to connect the player to the TV with HDMI cables for better quality.
Whether there 3D Blu-ray Discs or 3D DVD’s, quality can differ greatly from each movie. The resolution is one factor that affects quality. Another is the film itself, for instance how much of the motion picture was shot in 3D. As an example the popular movie avatar was shot mostly in 3D and gives the viewers breathtaking vistas that you can almost touch. On the other hand other movies might not be as capable, with only certain items appearing as three dimensional and only a handful of scenes popping out at you.
