Summary

It seems  that  everyone  is talking about  3D television these days. The introduction of 3D- TV is becoming increasingly feasible because of recent technologies and breakthroughs in image processing, display design and camera development as well as an improved understanding of 3D human factors.

Transformation of 2D to 3D

For 2D  animation,  everything happens   on  a  2 dimensional  platform.  Pictures are  flat,  without depth and offer only one perspective. Objects and characters are usually drawn without the subtle soft shadows we see in real life and colours have few varying shades.  In 3D animation,  everything happens   on  a  3  dimensional  platform.  Pictures have depth and offer multiple perspectives just like in real life and have soft subtle shadows casted on the objects and characters within.
In 2D, characters  look cartoonish and unrealisitc. In 3D, characters can look cartoonish but realistic at the same time.
Another way to think of this is to think in terms of a painting and a sculpture. 2D is a painting, and 3D is a sculpture. 3D introduces “depth perspective,” so we not only see a rectangle (2D) but a CUBE (3D).

3D Technology

The first 3D started millions of years ago with man. Yes, we all see things in 3D. All humans have binocular vision. What that means is that we have two eyes separated by a space of 2-3 inches. This enables us to perceive depth and see the world in
3D. This separation causes each eye to see the world from a slightly different perspective. The brain combines these two images into one. It comprehends the spatial differences and uses them to calculate distance. This is how we sense depth and distance.

Anaglyph

Anaglyph technology involve creating imaging that is three dimensional through the use of two images that are used with the primary colors of blue and red. The two images are created by placing two cameras side by side with the lenses about 2.5 inches apart which is the common distance between human eyes. One image is placed on the left and utilizes red color lines and is combined

Polarized glasses

The viewer wears low-cost eyeglasses which also contain a pair of different polarizing filters. Two synchronized projectors project two respective views onto the screen, each with a different polarization. Each image is projected with a polarization mutually orthogonal (90 degrees) to the other polarization. As each filter passes only that light which is similarly polarized and blocks the light polarized in the opposite direction, each eye sees a different image.

Methods of 3D Images

The secret to 3-D television and movies is that by showing each eye the same image in two different locations, you can trick you brain into thinking the flat image you are viewing has depth. There are several methods that 3D television manufacturers use to create 3D images on an LCD television
