Finally, a computer program using a Magic Eye-patented algorithm takes the image model and the pattern and orients repeating patterns to the intended depth of the hidden image. Then, they create a 2D pattern to camouflage that image. Magic Eye – which got its start in 1991 when engineer Tom Baccei, 3D artist Cheri Smith and programmer Bob Salitsky began building on Julesz’s and Tyler’s research – works by manipulating a repeating pattern to control the perceived depth and hide a three dimensional image in a two dimensional pattern.Ī Magic Eye image starts with a programmer creating the hidden image (a schooner, for example) as a grayscale, smooth gradient depth map where dark points that should be furthest away are darker and closer points are in lighter shades. The brain then perceives depth, with the two points as being on a virtual plane behind the pattern. When presented with an image like this, your eyes might each look at two different points, but because the image is a repeating pattern, the brain is tricked into thinking that the two spots are the same thing. Their research revealed what was happening in the eyes and brain when viewers looked at stereograms. Twenty years later, a student of Julesz’s named Chris Tyler and computer programmer Maureen Clarke, discovered that the same thing could be done with just a single image.

This supported his idea that depth perception happened in the brain, and not in the eye itself. Create your own 3D-image by drawing your own grey scale image - Use grey scale images you created before, or downloaded from the internet - Choose your own pattern for the creation of the stereogram - Save your. Someone viewing the two pictures side by side perceive a circle floating above the background, even though the random dots had no depth cues. Create your own autostereogram These images, known from the magic eye books, reveal a hidden 3D image. Then, he’d select a circular area of dots within the image and shift that area slightly in a second image. Dynamic Random-Dot Stereograms Reveal Up-Down Anisotropy and Left-Right Isotropy Between Cortical Hemifields. Julesz would generate one image of uniform, randomly distributed dots. Now computers were used to create autostereograms.Īn autostereogram is a single-image stereogram (SIS), designed to create the visual illusion of a three-dimensional (3D) scene from a two-dimensional image in the human brain.Magic Eye's granddaddy was the random dot stereogram invented by neuroscientist and psychologist Bela Julesz in 1959 to test people’s ability to see in 3D.

Of course, with the emergence of computers in later years things changed a little. Both a dream and a horrible nightmare, Tutti Audio has unveiled its new stereogram turntable console, integrating a host of pricey audio components into a drinks cabinet-come-cockpit with what it calls a mid-century twist of retro. They were a popular form of entertainment for people in the late 1800s and early 1900s. By either crossing or diverging one's eyes, a third image would eventually appear in the middle. It had a clip for holding special stereoscopic cards in place.Ī person would peer through a binocular system, which forced each eye to see only one of the two images.

This new improved stereoscope was a simple device with a special viewer. Later, in 1861, Oliver Wendell Holmes Sr, ( author, lecturer,physician and professor ), invented an improved form of stereoscope that became quite popular. Whether you’re looking at a printed stereogram or one on your computer monitor, get as close to the image as you comfortably can. Method 1 Getting Up Close 1 Place your face directly in front of the stereogram. This is a viewing device which allows users to create a three-dimensional image from a set of two-dimensional photographs or drawings. Fortunately, it only takes a few key things to view stereograms and see the world in 3D again. With a combination of prisms and mirrors, Wheatstone, designed and constructed a stereoscope. In 1838 a British scientist and inventor, Charles Wheatstone, discovered the stereogram through his explanation of, binocular vision.īinocular vision is the ability to maintain visual focus on an object with both eyes, thus creating a single visual image. Some other forms of stereograms include Anaglyphs and Autostereograms. A stereogram is an optical illusion a flat two dimensional image that reveals a three dimensional image if viewed in a certain way.
