4 Technological Innovations Of 3D Movie

After the invasion of Avatar, Titanic 3D comes back to life and sets sail again in recent days. It succeeds in drawing people’s attention. 3D movie, the term is no longer strange to us since the great success of Avatar. In the new era of 3D film, 3D technology is now fading its mysterious ring and being applied to various fields.

As early as 1838, 3D technology started its legendary journey. Though the first 3D movie was released in 1915, it is Avatar who helps 3D movie reach its peak. In the post-Avatar period, various movies are made with 3D technology attached including Titanic 3D, Toy Story 3 and Alice In Wonderland.

3D technology makes full of the different viewing angles of our right eye and left eye to the same object in order to create two layers of images in our mind. After that, the illusion of a 3D image comes out. The development of 3D movie promotes technological innovations of 3D technology. This post will show you 4 technological innovations of 3D movie.

1. anaglyph 3D

In order to make movies with anaglyph 3D attached, two cameras, equipped with red and blue filters, are required. With this method, an image will consist of red color layer and blue color layer. When watching anaglyph 3D movie, a pair of red/blue anaglyph glasses is required. The red color layer will go to left eye while the blue color layer to right eye to create 3D effect.

Nowadays, anaglyph 3D is widely used for its low cost. However, the 3D effect of movie made with this technology is not that good as well. Anyway, various applications are developed to help you attach 3D effect to 2D movie. For example, DVD Ripper can help you convert DVD to various formats with 3D effect attached.

2. Polarized 3D

By adopting this 3D technology, two projects, both equipped with polarizers, are used to play two similar images synchronically. They will help you to polarize two images in order to make sure that one image goes to your left eye only while the other goes to your right eye only.

Of course, a pair of polarized 3D glasses is required to help you prevent one eye from viewing the images that are supposed to be received by the other eye only. Polarized 3D technology is popular in cinemas because it can provide audiences good 3D effect. However, its high cost has prevented it from being popularized.

3. Active-shutter 3D

Active-shutter 3D is used in 3D TVs and projectors, which is not only good in effect but also cheap in cost. You need a 3D TV and a pair of active-shutter 3d glasses. While watching 3D TV, the glasses will automatically block one eye in order to let the other eye receive the image only. So you can only view the image one time for one eye only.

Since it does it quickly, there is no way you can find one of your eyes is blocked. Unconsciously, you are receiving two images in a short time and then the brain will process those two images to make them a 3D image.

4. Glass-free 3D

People are reluctant to wear glasses and then glass-free 3D technology is adopted. Auto-Stereoscopic displays display different pixels to each eye, using optics (lenses or barriers) to direct the correct pixels to each eye. Glass-free 3D technology is still so immature that its application scope is limited. However, two 3D mobiles with glass-free technology are available in the market at present so you can buy them to experience the effect of this technology.
