What are 3D anaglyphs?

The three -hour (3D) anaglyphic glasses are pieces of glasses designed to convert a specially coded two -dimensional (2D) images to three dimensions. There are one red and one blue or azure, a lens for filtering different parts of the anaglyphic image that the eye reaches, which eye. Thanks to their simplicity and low costs, 3D anaglyphs remain ubiquitous in 2011, although there is excellent 3D vision technology. With a conventional 2D image, there is only one "eye", usually in the form of a camera lens, capturing the original image and eliminating the information necessary to create deep stimuli. To capture the 3D image, the creators of the contents usually use two cameras running simultaneously to capture the image from two slightly different angles and reflect what two eyes do. The images then combine together using any of the technologies such as Anaglyph, then Be, when the viewer sees a picture.

In the anaglyphic 3D image has one of two capture devices over its lensThe red filter and the other have a blue or azure that is almost turquoise, filtered through its lens. These tinted images are overlapped over the second and printed. When the viewer wears a few 3D anaglyphic glasses, color lenses direct two different images to each of his eyes and his brain combines two pictures into one 3D picture.

3D Anaglyph glasses are usually quite cheap. Cardboard versions are often wrapped in movies, books and even cereals as gifts. For those who need a better 3D image, 3D anaglyphs with plastic or glass lenses are also available, albeit at higher costs. The best of these glasses not only filter color, but also replace the different ability of the human eye to solve different colors, giving more accurate view of decoded 3D image.

Anaglyph technology has existed since the 1950s. When the paintings were produced black and white, it was excellent technolOgie, because compromises in the color of loyalty required by the wearing of color lenses were not published. In modern full color images, Anaglyph 3D is much less suitable, because the colors used to coded 3D information are also present in the actual image. Anaglyph 3D glasses are gradually replaced by polarized glasses or glasses with liquid crystal closures (LCD), which prevent one eye to see the image of the other eye. In addition, 2011 recorded the first wide edition of 3D applications without glasses on handkerchiefs and mobile phone screens.
