Autostereograms date back to 1959 when Bela Julesz with MacArthur Fellow came up with the stereogram. This discovery occurred while they were working on differentiating between camouflaged objects hidden in pictures taken from the air by spy planes. He decided to research a little bit more into his findings. He used a computer to design random dot images, which when seen through a microscope, revealed itself as a 3D image.
His findings proved that depth perception doesn’t just occur in the eye, but it’s part of the neurological process. In 1970, Masayuki Ito, caught the wind of Julesz’s findings, and designed an image using stereogram. However, it was much later on, when Christopher Tyler discovered autostereograms.
The Discovery of Autostereograms
It was the year 1979; when Christopher Tyler sat down to combine the different theories that were the grassroots of the random dot stereogram and single-image stereogram. The combination of the two theories created something truly spectacular, an autostereograms.
The autostereograms interested people because it allowed them to see the 3D image from a 2D image without needing any kind of optical equipment to do so. Two computer programmers, Tom Baccei and Cheri Smith, picked up his discovery in 1991 and designed a color random dot autostereograms, popularizing it as Magic Eye.

What is the Magic Eye?
The Magic Eye is described as a three dimensional picture hidden amongst a two dimensional picture. They are known as the advanced technique of producing stereogram. Here are the steps used to create The Magic Eye:
· Create a 3D Image
The 3D image should be rotatable and editable. People with an artistic ability will be able to produce a usable 3D image. However, you would still need to know how to use 3D software.
· Rendering the 3D Image
You will need to create a 2D pattern to hide the 3D image. For this, you must be able to render the image well so the picture remains hidden.
People with the knowledge of using the software along with having an innate artistic talent will be able to create a spectacular Magic Eye to enchant viewers. Let’s track back to understanding the method of creating autostereograms, as this was where it all started.
How Are Autostereograms Created?
Autostereograms are created using spacing to create a three dimensional picture. For instance, if the pattern is repeated at lesser distances, the area will appear closer to you. The opposite will be true if the patterns were to be repeated over longer distances. If you want to see this illusion, do check out What’s Hiding Here? Not to give you any spoilers, but the illusion has something hidden inside it. Can you see it? If you can, you will be able to say that the picture pops at you. You can show this illusion to your friends and family as well.
To conclude, autostereograms are a fun way to pass time. So search the web for some when you are bored and you will be amazed at the different pictures hidden in each. In the two opticals shown here we have taken a couple of normal magic eye pictures and mixed them with real pictures to make our type of autostereoram. Original picture sources unknown.
