Answer 1

Are made... in a given year? month? in film history?

Please be more specific.

Answer 2

Virtually all systems involve using a pair of camera to film the original movie. The two cameras are placed beside each other at the same distance as the separation of human eyes. This gives you two films; one for the left eye, one for the right. The next stage is in projection - there are two mechanisms widely used so the the left eye receives the information from the left film and the right eye from the right. The two most common techniques is to use colour filters; the left film is passed through a red filter (say) and the right film passed through a green filter. Viewers have to wear special glasses with corrosponding coloured filters so the the left and right images arrive at the correct eyes. The problem with this system is that, understandably, the colours of the film is distorted by the filters. A more modern technique uses polarised glasses; polarised light will pass through polarised glass only if they are both polarised in the same direction, by using horizontal polarised glass in one lens of the glasses and vertical in the other, and projecting the left and right films with corrosponding polarisation the left and right information is correctly received. The advantage of this system is that the colour information in the film isn't distorted by the 3d system, the disadvantages is that a special screen is required to maintain the polarisation and the glasses are relatively expensive. A third system is to use shuttered glasses; these are special glasses that alternately blank out the left and right eye in synchronism with the projector which alternately projects left and right frames. This system is rarely used for public projection, it does get used for home computer games occasionally.

Answer 3

2D is a movie where the characters are flat on a screen, what we usually see on television and in theaters. 3D is where the characters on the screen seem to pop out like in real life, they are not flat. In 3D movies, special 3D glasses are required.

Answer 4

It depends on the movie. Doug Walker once said that how you can tell a good 3D movie is by how well you can see things. If the movie is very dark, or has lots of blurry action scenes, or is made up of mostly talking instead of action, it might not do much for you. If you can see everything clearly and there is a lot of action and special effects, then it'll probably be more enjoyable.

Answer 5

The use circulaly polerised lenses which means that you see a slitly diffrent image through each eye.

Answer 6

well the difference between a 3d movie and a normal one is the 3d movie you watch comes out at you when you wear 3d glasses whereas if you didnt wear the glasses its just a normal movie.

Answer 7

they use special IMAX video cameras
