How 3-D Glasses Work

The reason for wearing 3D glasses in a movie theater is to see various images like View - Master. Two images are actually displayed on the screen, one of the images enters one eye by the glasses and the other eye enters the other eye. There are two general systems that can do this.

The red / green or red / blue system is currently mainly used for the 3D effect of television, and it is used in many old 3D movies. In this system, two images are displayed on the screen. One is red and the other is blue (or green). Filters for glasses have only one image in each eye, the rest are your brain. If you use colors to separate colors, you can not actually create color movies, so the image quality is not as good as the polarization system.

In Disneyland, Universal Studios, and other 3D venues, you can see the color, so the preferred method is to use polarized lenses. Two simultaneous projectors project two corresponding views with different polarizations onto the screen. Since glasses contain lenses with different polarizations, you can enter only one of them.

There are also more complex systems, but they are not widely used because they are expensive. For example, in some systems, the television screen alternately displays two images alternately. Special LCD glasses block one eye and then block the other eye. In this system you can see the color on a regular TV, but you need to purchase special equipment.

Many efforts have been paid in "3D unmanned glasses without glasses" (in particular, the Soviet Union who have used vertical slats for many years), but viewers have taken out of two special eyeglasses You must wear one of them. . In the initial stereo photo system, one lens of the glasses was red and the other was a green lens (after blue). Images on the screen without glasses are displayed as two slightly offset images. One is a red line and the other is green. Each lens of the eyeglasses darkens the opposite color so each eye can see only the images used for it.

A film with a stereoscopic shape or appearance that gives the illusion of lively depth, usually a special red / blue (or red / green) polarizing lens, is attached and when the three dimensional image interacts and feels the scene This experience is called virtual reality and 3D experienced its heyday in the early 1950's; also known as 3D, 3D, 3D, natural 3D or 3D example: the first major 3D feature film is Bwana Devil (1953), House of Wax (1953), Cat Womans of the Moon (1953), MGM Musician Kiss Me Cate (1953), Warner 's Hand (1953), Hitchcock Dial M (1954), Universal Black Lagoon Creatures from (1954), Comin'At Ya! (1981), part of Freddie's death: last nightmare (1991), spy kids 3D: game over (2003)
