Understanding The Ancient Art Of 3d Imaging.

Many people would think that 3D technologies have only existed for the last few decades

. It is extremely surprising to find that the initial concept was attempted almost 170 years ago! It is incredible to consider it has actually been around as long as photos and regular 2D motion pictures.

Stereoscopy, today more commonly known as 3D imaging, creates one easy principle: Two images are obtained from slightly different angles or vantage points. When viewed together, your mind automatically combines the 2 2D images into one 3D image. There are three different ways to present these different images to every individual eye:

The viewer can wear glasses that combine both of these images from two different sources.

Glasses could be worn that filter two different images from one source.

The images can be split with a light source into the eyes. In this case there's no need for glasses.

The concept of 3d imaging was originally studied and attempted long ago in 1938, by Sir Charles Wheatstone. He used both lenses and mirrors to make a 3d image. A few years later in 1844, the idea was improved by Sir David Webster. Webster did away with the mirrors and came up with a design which has changed hardly any to this day.

In 1861 Coleman Sellers was one of the first individuals to try and project actual moving images in 3D. He'd show a sequence of captured still images in quick succession, giving the viewer the illusion of movement.

In 1891, a method using anaglyph images was patented by Louis Ducos du Hauron. When viewed with glasses with two different colored lenses, the anaglyph image is revealed in as a 3d image. This technique was the first passive 3D system. The anaglyph systems used green and red lenses, but since 1971 cyan and red have been used.

The first public screening of a 3D film was presented in Ny, at the Astor Theatre in 1915. The film was called Jim the Penman, and also used anaglyph technology. Two separate film strips were projected alongside each other, and the audience were given tinted glasses in order to begin to see the stereoscopic images. The anaglyph technique does have drawbacks, mainly the fact that there's a slight ghosting effect. In 1952, using polarising filtering lenses this ghosting problem was overcome, along with a new trend in 3D technology was created.

Considering the humble and primitive beginnings of 3D imaging, it's astounding to reside in a time where there is really a surge in 3D technology. The days are gone of anaglyph images, as Active 3D glasses have taken the market by storm. There are even Bluetooth 3D glasses to avoid pesky cords and cables. Samsung has been at the forefront of active 3D research and has majority of the marketplace share. If you are going to venture into the 3D realm, be sure you purchase Samsung Active 3D Glasses or at best 3d Glasses Suitable for Samsung.
