The 3D TV has been the recent innovation made by the company’s manufacturing TV The newly released movie named avatar has brought up this concept of using 3d technology These companies now are eager to enhance the technology that they use in making their products and add 3D features. The image has so much of clarity and it is because of 3D glass that is used now . There is no comparison at all with its earlier counterpart as this TV with 3D glass makes viewing all the more interesting . This has been designed exclusively with the idea of giving premium enjoyment to the viewer . So for such old people this technology is a blessing and they can now enjoy TV with clarity as never before . There are two kinds of images that you will get from 3D When you are watching a TV with 3D glass, you will feel as if the images have come out of the TV and are right in front of you and you will feel as if you are in a realistic scene What you see is incredible but true The 3D TV is also taken over by another innovation which is 3D TV without glasses.
How 3D Technology Works :
The Basics of 3D Technology
3D technology is a very simple process in nature. Basically, to create a 3D film, two images must be superimposed together on the same screen. This is done by sending each image through a polarizing filter and then projecting it on the screen. Currently eye glasses are needed to view the 3D image.
The eye glasses are a vital part in 3D technology. Each side of the glasses contains a different polarizing filter which only receives one of the two images on the screen. Therefore, when watching a 3D film, your eyes will receive the same image, but from two different filters - or perspectives. And this is what gives the illusion of depth and 3D.
3D technology has taken a great step forward in recent years, with such films as Avatar and How to Train Your Dragon. A new 3D technology called 'RealD' simplifies the process by having a polarizing filter placed in front of the lens which can switch polarities 144 times per second. Therefore, with RealD 3D technology, only one projector is needed.
Different 3D Glasses and Technology :
There are many different 3D technologies which have been developed over the years. They are:
•Polarized 3D Glasses.
•Eclipsed Method. In this method a shutter blocks light to one of the eyes, when the other image is displayed on screen. Then the image alternates, and the light is blocked from other eye. This happens many times a second, and creates a 3D image.
•Interference Filter Technology. This is the classic 3D technology. Using different wave lengths of color for each eye, the brain perceives two similar, but different, 3D images. This eliminates the need for a polarizing screen, but makes more expensive glasses necessary.
3D Technology - 3D Without Glasses :
Is 3D Without Glasses Possible?
Yes 3D without glasses is very much possible. Actually the way your eyes, and brain, are set up, it's almost like it supposed to be used for 3D. What happens is that your eyes receive separate variation of the same image (due to the difference in how the iris, the angle of the eyes, and many other aspects). When this happens the brain has to meld the two images together to make a single picture for you to see. Many times, like with 3D technology, the separate images fools your brain into thinking there is depth and a 3D image.
Many of the principals of 3D technology without glasses uses this principal. Also many 3D perceptions are used by the illusion of movement. This 3D technology is called motion parallax. Its the different movements of objects in the foreground and the background. Think about when you walk away from something, certain objects get closer and certain objects get farther away. Motion parallax basically simulates that and created a 3D illusion.
The Future of 3D Technology
The future of 3D technology looks brights. The most notable 3D product coming out in the next year is the 3DS, a hand held system from Nintendo which promises to display a 3D image without glasses. Initial reaction to the system is good, and the it seems to be using Lenticular viewing. This means that the DS has to be held at a certain distance and can't be moved wildly in either direction. This could be seen as gimmicky to some, so the success of the product is still up in the air.
Many TVs are starting to come on the market, with many new ones becoming available over the year. In gaming the Nintendo 3DS looks to be the flagship; it already has announced that it will have games such as Ocarina of Time, Star Fox, and other classics - all in 3D
