With the high tech development in visual and graphics, 3D movies are made possible and it slowly beat their 2D counterparts. In the past five years, about 20 3D movies have been produced with the latest one is “Up” by Disney’s Pixar. There are about 50 more 3D movies in production and is expected to hit the theaters soon. Why movies producers are getting crazy in producing 3D movies or animation? One reason for the surge is that theater owners have found they generally can charge more for three-dimensional films than their two-dimensional counterparts, analysts and industry experts say. What’s more, 3-D movies tend to sell more seats per showing, they say.

In Hollywood, 3D movies are proven to be profitable said some of the experts. They are now planning to put this technologies at home! Already you can find computer monitors and televisions that say they are “3-D ready.” If we traced back the development of 3D technologies, we would find it started since the early days of still photography and moving images. They try to trick the brain into registering a three-dimensional image by tapping into people’s stereoscopic vision. Each eye is shown its own image that naturally overlaps with one seen by the other eye. The brain puts the two together to create a three-dimensional picture.

In 1950s, 3D images were produced by two different images by overlapping blue- and red-tinted images. spectators were able to see a 3-D image by wearing goofy glasses with one red lens and one blue one that canceled out the tints on screen. Then, the techniques were further developed by using polarized glasses to watch 3D images. Viewers had to wear glasses with lenses polarized in two different ways. A polarized lens or filter acts like the teeth of a comb; only light of the same polarization will pass through the glasses (i.e., whose waves are parallel to the comb’s teeth can pass through.)

The latest iterations of 3-D still typically require viewers to wear glasses but with a bits advancements – i.e sometimes polarized glasses, sometimes glasses with electronic “shutters” that alternately close over each eye. But they rely on computer technologies, such as digital video projectors and computerized production, to get the 3-D effect.

In general, electronics advancement especially in virtual images are really benefits those who crazy to experience the beauty of 3D movies or animations.
