Getting 3D from 2D and the Difference Between Old and New 3D




For many consumers right now, buying a new set of 3D-enabled television is almost impossible because of the cost restrictions. But still they can join the revolution called 3D even with the old 2D television sets. And it can all be done in the name of conversion.

Consumers with the traditional television sets can also get 3D images even from 2D screens. So how will the conversion happens? In order to properly understand the process, it is recommended that you take a look first at how the technology works when viewed.

Usually the 3D theater screen that shows 3D images and moving contents are known to show two types of images of the same scene at the same time. The first set of the images will be for the right eye of the viewer. And the second set of images is for the left eye of the viewer.

Now these two full size images occupy the whole of screen and it looks like that it's linked with each other, sometimes the first image is skewed to the right and the one on the right seems to be skewed to the left. This is the kind of image that is seen by the viewer if the 3D glasses are not used. But when the 3D glasses are used, then the two images will be seen as one single 3 dimensional image. This happens because of the process called stereopsis. Remember that the human eyes are separated 2.5 inches and this kind of arrangement allows for each of your eye to see an image from a different angle. But when the 3D glasses are used for different viewing experiences, then the two separate images are combined and that the illusion of depth is made.

The discussion about the new 3D technology is never complete without discussing the differences between the 3D of today and the 3D of old. Yes, there is an old version of this technology. Perhaps you remember the time of the anaglyph method where the lenses of the glasses are often tinted red or any other color and then these are used to create false-color images.

The end results are discolored images and images of low resolution. This was your old attempt at 3D. And the newer version of this technology brings to fore better improvements that heighten the viewing experience. For example, the current offering of this technology can deliver full color and images in great resolution often coming in the full-blown 1080p high definition. And even the lowest resolution of 3D at this stage still looks good.

The new crop of high definition 3D television sets and personal computers are also different now in a sense that the requirement for glasses have changed. In the past, any glasses will do. But this time around, the new and improved technology calls for a different construction of the lenses. The 3D glasses of today calls for active liquid crystal shutter glasses. Plus the new 3D glasses call for electronics and rechargeable batteries that can sync to the television.
