what is 3D???

What is 3D?

Types of 3D
Many colleagues have expressed doubt that 3D is the kind of true for them.
I do not intend to make a wiki entry, just something simple to serve for beginners in the world of 3D.
I will distinguish two types of 3D:
- Anaglyph not need specific hardware.
- Stereoscopic and 3D Digital , you need to view specific electronics, but really the two systems are stereo.
The aim of the 3D display is that, from a flat image, we get to perceive a sense of depth.
This is achieved by showing each eye a picture out of step with each other. This is done by capturing images with two separate chambers a few inches while then together with the technique we use for viewing.
It is the "old" system marketed under the name IMAX 3D patent in 1900.
is to filter the image to each eye to see primary color filters. We have contributions in this format, you specify in the title, you can do with any player. The contributions are in digital 3D format, can also be visualized with this technique.But we need a software to filter and combine the LR images (left and right) as Stereoscopic Player or Arcsoft Total Media Theatre with 3D plugin ( configuration ). These programs also serve to which you have hardware 3D (3D TV, Nvidia, 3D DLP projector, etc).
The result is a single image with colored edges, depending on the filters used. By using a few glasses with colored glass, usually red / blue, these edges are removed and 3D depth is achieved.
The advantage of this system is that it is very economical, no need to buy anything, just the glasses . Against that we have the color filtering, each eye will remove a primary color, 33%, so we have a significant color distortion and punishment for the red eye.
Digital 3D
The system that is being implemented domestically and 3D theaters.
There are several systems, Real 3D, Digital 3D and IMAX 3D Digital. XpanD X103 Universal, which are compatible with all Samsung TV except with the 2011 that go bluetooth. Most have 3D TV media player with USB, you click the USB hard drive and plays it's own TV. For this, use the SBS format movies, Side by Side. If we reproduce these films in a normal PC player will see an image next to each other (two pictures apparently identical), clicking on the TV, select the movie and you put the 3D mode in SBS or UD if the images are on top of each other. Some TVs do not allow enable 3D mode from USB, these media must use an HDMI or PC for normal playing. Some of these problems are contained 3D sound and subtitles on TV ... usually depending mkvmerge is solved by passing it through version 4.0 or lower without touching anything or eliminating content that does not interest us. Another format we can find is ISO or FULL BR, this is a complete disk image to burn business and play hard in BR BR 3D . You can also extract the contents and process it to get a SBS. For now I'll have to leave so the pictures and enlarge another day ...
The first uses a polarizing filter to enhance a vertical and one horizontal, the glasses have a polarized filter so that each eye sees a different image in full color. The glasses are cheap but not easy, at the domestic, have two panels or two projectors polarized.
The second, digital 3D, is being implemented domestically. The glasses are active and receive a sync signal from the player. The image is at 120 Hz (60 Hz for each eye) and is "turning off" the glass in the glasses alternately synchronized with the image. The third, without much success, is very similar but with the typical IMAX film.
They're trying to do 3D without glasses , and e n 1838, Sir Charles Wheatstone invented the stereoscope, a simple device that could see two special cards slightly displaced images, which were perceived as a single stereoscopic image.Despite the ingenuity of invention, has one major drawback, just an observer, placed in a very specific position on the card, you can enjoy the 3D effect. The same happens in any console, camera and camcorder 3D. They use micro-pixels or inclined, so that the image that reaches each eye is different. Some TV manufacturer has presented TV withoutglasses with microperforated panels that are visible from a modest seven points 3D effects of the room. With these systems is achieved depth in the picture, but I have not seen any sense that it leaves the screen.
Returning to the issue of digital 3D. In Cinemas 3D glasses and IR active sync code for each room. Not suitable for home.
3D TV, each manufacturer has its glasses compatible with each other and their exclusive movies ... Although there are some,
PC, Nvidia 3D Vision, only with their glasses .
projector, all projectors 3D Ready feature a system called DLP Link ® through the glasses synchronize directly with the screen. Most projectors are capable of processing 3D image by alternately software needs to put him LR images.
