The 3D technology has a rich history as it was studied by man for many years until it was modified as we see it today. Man, at first wanted to understand the process of it the technology and how does it work. The person who first described the process of stereopsis was Sir Charles Wheatstone, way back in 1838.
It is the process by which human beings are able to perceive the three dimensions through their eyes. The technology of 3D basically means man is able to perceive three dimensions i.e. length, width and height. It was on until David Brewster, in 1844, invented Stereoscope which was able to take 3D photograph images.
The first 3D photograph which came into limelight was in 1851, when Louis Jules Duboscq presented a picture of Queen Victoria at a Great Exhibition. It was then that the using well improved technology became well known all around the world. This made the people throughout the world go crazy for this new technology and they tried to own it and click pictures in stereoscopes. The first picture of Queen Victoria is as follows-
From then on, the craze went on increasing and men have tried to improve the technology even more. The first Stereo animation camera was invented and it was known as Kinematoscope. Following this invention, was the filming of first anaglyphic movie in 1915. In 1922, the first anaglyphic (The Power of Love) was shown in the theatres. Further, in 1935, the first colour anaglyphic was shown in the theatres. This marked the beginning of the 3D technology movies in the history.
3D technology has overgrown much owing to its huge use in other sectors. The history of 3D printing is now possible now because devices are made to print three dimensional figures. MakerBot, a global leader in the 3D industry introduced a machine which can even help to share 3D print files between two people and work on the same project as printed from the 3D print files. It was thought impossible at first, but now it’s a reality. In the 1980s the technology of 3D printing started. Firstly, it was made with the help of LASER.
The 3D technology came to a standstill in the middle 1900s, after the discovery of first 3D glasses which consisted of red and blue glass, one each in a single glass. This was made to decode the two basic colours consisted in the motion pictures, red and cyan. The 3D pictures contained two filtered colours and when they passed through the coloured glasses, human eyes perceived them and as a result, they saw 3D images and enjoyed 3D motion pictures. This is because the brain fuses both the images seen by both the eyes and the result is that the human beings are able to see the 3D pictures.
But this process had a drawback as the people were not able to see other colours other than red and cyan. In 1922, at the Ambassador Hotel in Los Angeles, the first full length 3D movie was opened to the audience.
Then, after a gap of some years, in 1960, Space Vision camera was invented which changed the perspective of filming of 3D movies. Then came the polarised glasses in 1986, which was introduced at World’s Fair in Canada. The polarised glasses the way people used to watch 3D movies, as it had the power of viewing all the colours in a 3D picture (the drawback which was with the filtered colour glasses).
In the process of polarisation, two images are superimposed in a single screen. It is displayed through different polarising filters to create the stereoscopic effect or the 3D effect. The people perceive it as the 3D images as the polarising glasses creates the effect in the human eyes giving it the dimensions, which human eye can perceive.
Then with the course of time, the technology improved. The process of stereolithography was devised and the process of 3D printing became far easier. It is easy to handle the software and the person wanting to get a 3D print done doesn’t even need to know about software or how it works.
The material used for 3D printing is diverse as it creates 3D prints with almost every possible material. People have tried with even chocolate and with got satisfactory results. The best part of 3D prints is that the efficiency of these machines is high. Food materials are being produced at a hotel in Netherlands.
In the 21st century, James Cameron, director of Avatar, the film which has been acclaimed as the best 3D film till date. Many movies have used 3D technology like Polar Express. Many educational shows and others are being held from 2010.
As a conclusion, it can be said that the technology of 3D is improving and it is expanding constantly in every sector. The prices are also expected to go lower due to its expansion.
