The world of 3D
It often feels that very year there is a new technology introduced that revolutionizes the way we watch our favorite movies and TV shows. Flat screen TVs, plasma sets, LED and LCD models have all dramatically improved the home viewing experience. Now there are 3d TVs and 3D glasses available that take things to a completely new level.
You probably remember the old fashioned anaglyph red and blue glasses, the kind that could have been made out of candy wrappers, now the options are far more advanced such as color-code 3d amber blue glasses. The basic principle is the same, to be able to view otherwise flat images in three dimensions. Just imagine what a difference this can make to the viewing experience. Now it will really feel as if you are in the middle of the high octane action that is on the screen.
In actuality 3D movies have been around for many years. The first 3D creations were produced as far back as the fifties. During the seventies and eighties films such as Jaws made the concept famous. Today the technology has come on leaps and bounds. Movies such as Avatar have taken 3D and brought it bang up to date to a massive audience. It is a style that will only continue to grow in popularity in the future.
There are two basic methods of watching a 3D TV, these are with anaglyphic or polarization glasses. As it is believed that in the future there will be massive interest in the technology, many of the leading names in the entertainment industry are investing heavily in the concept. This includes firms such as Nvidia, Sony, and Panasonic.
Anaglyphic 3D glasses make use of red and cyan lenses; these are also referred to as stereoscopic glasses. A pair of polarization glasses would work in a similar way but pick up the different polarization which is being displayed by the projecting devices.
There are new ideas relating to 3D that are currently being tested. One example being alternate frame sequencing. This involves the use of LCD shutter glasses and alternating frames which produce a stereoscopic image.
Perhaps the biggest interest is in another technique known as auto-stereoscopic. With this the person viewing the images does not need to use any type of special glasses. The image is projected using a parallax barrier or lenticular lens. Which technology comes out on top we can only wait to see.
