3D technology

3D technology enhances the illusion of depth perception. It enhances the image and makes it appear more clear and deeper. (Gordon, 2010)

History of 3D technology

History of 3D can easily and closely be linked to the photography. In 1844, David Brewester invented a stereoscope. This device had the capability to capture the pictures in 3d. In 1922, the power of love was released. It was the first public 3D movie. In 1950, 3D made a comeback. In 1960, space vision 3D technology was released. This was two images printed on top of each other on a single frame. It only needed one projector and one camera. The first film to use this was the bubble (1966). In 1970, Allan Silliphant and Chris Condon developed stereovision. In 1990, many IMAX 3D films were made. In 2003, the Polar Express was the first full length animated film to be released. In 2005, Grauman's Chinese Theatre in Hollywood was the first commercial movie theatre to have digital 3D technology installed. In 2010, Sky UK pushed towards 3D TV.

How 3D works?

Determination of depth in visual system

If we close one of our eyes and open other and then close one and open other it would gives us a different image of the same object. This happens because of distance between the two eyes. This difference between the eyes is called interocular distance. When we take a look at something very closely the object begins to appear double in the background. It is because we focus both of our eyes to look at the same thing. This is called convergence. This process of convergence creates sort of “X”. This appears to be like following picture. (Omale, Nicholas, Hung, Wei-Chen, Luetkehans,& Lara, 2009)

The image at the centre point of “x” unites together on retinas but because of the phenomenon of interocular the image that we look at hit different points on retinas and that is how we get to see double image.

When an image is passed to retinas it further go through the various system of the vision system and form the pattern, colour, mode and different things to form a final image.

Creation of depth display in 3D

In a very simple and straightforward way it can be said that 3D display brings more depth in the image by creating a separate image for each eye. But this process is not that simple various techniques are used in order to achieve this objective. (Omale, Nicholas, Hung, Wei-Chen, Luetkehans,& Lara, 2009)

Filtered lenses

What a filter lens does is that it sends half portion of an image to one eye, while, half of the portion to other and half to both the eyes. Then brain combines all the image and present the deeper image. The most complex part in this is of distribution of colour. Brain receives the colour in broken parts and then it gathers them in correct pattern. An advanced and new filter known as infitec break the colour in two portions and send it to ...
