A 3D display is something that we all find endearing. It has given a new perspective to the way we watch films. It is larger than life today. But what goes into making a 3D display? Research states that, it is a device made in a way which equips it to convey 3D images. This simply means that the image will have an over-all depth which can give that three-dimensional effect.
The principle that make up 3D which is the multi-view automatic stereoscopic technology have been known to man for a century now. But it is only recently that man has implemented these principles in workable technology. And over the years, as the 3D technology has evolved, it has become available to the common man for much less a price than it was for before. One of the reasons contributing to this is the rise in the use of 3D in film making.
3D was first deciphered and described by Charles Wheatstone in the 17th century. Through stereoscopy, a separate device is used to view one scene in three different ways. This means, the image is viewed by a person thrice. The technology was made of anaglyph images and one had to use polarized glasses. While watching a 3D image, one required using special glasses with red and blue lens.
Over the years, there has been a rapid growth in technology and it is ever-changing. And stereoscopy has evolved to auto-stereoscopy. An auto-stereoscopy is trickier and more advanced. It is a complicated display because now each eye of the user of this technology should be able to see the same image. And when the viewer turns or tilts their head, the display does not get disrupted and it remains the same. Hence, there is no blurring of image that can be seen. The depth illusion remains intact.
In addition to this, the auto-multiscopic display has pixels which are dependent on the views. This means they vary due to intensity requirements and colors from different angels of viewing. Hence, it can move in any direction; vertical or horizontal or left to right. But here there is a breaking down of image when there is movement. But given the perception of vision of the humans, the images appear to be unchanged. The technology helps to maintain the illusion as the image changes. Hence, one is not disturbed.
Hence, this is known as automatic 3D display as it has been coined by many companies and viewers alike. This means even when the image keeps changing one need not remove their glasses. The eyes of the viewer can easily adjust to the changes in the 3D display unlike the earlier situation. This causes one to enjoy 3D films more and causes less strain on the eyes.
And today, there are better glasses made for viewing 3D display. Plus, 3D films are now available on DVDs as well unlike before when they were confined to specialised theatres only. Today most film makers prefer making 3D films as they enhance the movie-viewing experience, making it seem larger than life.
