What is 3D

Three D a movie with images having three dimensional from or appearance

Our physical environment is three dimensional and we view the world in a 3D way every day.Human have two eyes which are about 2 inches apart so we are able to perceive the spatial relationship between the things just by looking at them.

Introduction

A 3D display is a screen that shows a three dimensional picture.

A 3D picture makes for a more interesting and real viewing experience.

In the past few years we have seen quick advances, and the TV, movie and gaming industries are betting heavily on 3D content.

The basic definition of 3D space stays the same

 Everything about the X, Y, and Z-axis still holds true, but there's one catch. While real world 3D objects physically exist in three dimensions, in the digital world of computer graphics 3D objects can only be representedmathematically.

How 3D Image is Created?

Stereoscopy refers to a technique for creating or enhancing the illusion of depth in an image by presenting two offset images separately to the left and right eye of the viewer. Both of these 2-D offset images are then combined in the brain to give the perception of 3-D depth.

Active 3D and Passive 3D

Active 3D

Active 3D could also be called powered 3D, because it requires that the glasses used be powered somehow.

 Early models used standard AA or AAA batteries, but the newest ones use rechargeable cells that draw power from special cradles, or even from a computer’s USB port when plugged into it.

Active 3D and Passive 3D

Passive 3D Passive displays have a special filter that works with the

polarized lenses in the glasses. Your left eye only sees the odd lines and your right eye only sees the even lines. Without the glasses, the screen looks normal.

Passive 3D is a lot like how it worked with those old blue and red lens type of glasses from the 1950s, only the modern ones work with full color images

Volumetric displays: Real 3D Images The most straightforward way to create a 3D display, is to

actually creating it in 3D. These are called Volumetric displays, and scientists are working on all sorts of way to create them, which usually involves lasers and rotating or vibrating mirrors

Auto-Stereoscopic Display

Auto-Stereoscopic displays display different pixels to each eye, using optics (lenses or barriers) to direct the correct pixels to each eye. The nice part is that you don't need to wear any glasses to experience the 3D image!

What’s on the Market? 3D Movies 3D Televisions 3D Gaming 3D Mobile Phones

3D Televisions

During 2009, many companies have started to talk about 3D TVs, and today most of the companies have already announced future models. These companies include Sony, Samsung, LG, Toshiba, Panasonic and LG. Most of these

TVs will be high-end models, usually LED-based LCDs.

Future of 3D TVs

Sony 3D TV, 3D games expected to boost sales of such televisions. This is the second year of 3-D TV availability for consumers in the market. 3-D sets are currently owned by about 1 million consumers

It is estimated that within two years the prices of 3D TV sets will decline and will become a common electronic device in every home.

3D Mobiles. 3D is a new big thing now. Year 2010 was more towards

pushing 3D televisions into consumer's houses and now 2011 and 2012 is all about 3D smart phones.

3D mobile phones are not available in the market but it is soon going to change. Companies like Samsung, LG, Sharp are on the verge of launching 3D mobiles phones in the market

Future 3D Mobile Phones

Proposed design for Sharp 3D phone that is to come around next year. It also goes head to head with the other companies like Samsung that will also provide 3D mobiles at the same period.
