What Is A 5:Level Autostereogram?

What is a 5: level autostereogram?

An autostereogram is a single-image stereogram (SIS), designed such that when viewed with proper viewing technique, i.e., the “magic eye”, it will produce an illusion of a three dimensional (3D) scene. The simplest type of SIS consists of horizontally repeating patterns and forms one complete image when viewed properly.

When viewed improperly, this yields only a vague and distorted impression of the original image. Autostereograms where more than one copy of the image is present require the brain’s stitching together of multiple images into one seamless whole to recreate the 3D scene correctly – resulting in a dramatic improvement in visual appearance.

In order for any successful form of stereopsis to occur, the two Eyes must perceive two slightly different images. The brain then fuses these two images into a single one, allowing an individual to see depth and perspective in a scene which is not possible from a single image. The level of autostereogram refers to the number of unique ‘layers’ or copies of the repeating pattern that are used to create the 3D scene. A 5-level autostereogram will have five layers of repeating patterns, while a 2-level autostereogram will only have two.

The more layers that are used in an autostereogram, the greater the visual effect, provided that the viewer can fuse all of the images correctly. However, as with any form of stereopsis, success with autostereograms is not guaranteed for everyone and can vary from person to person.

Some people find it difficult to ‘see’ the 3D scene in an autostereogram, while others find the effect striking and immediately addictive. The level of difficulty also tends to increase with the complexity of the 3D scene being depicted.

There are a number of different types of autostereograms, each with their own unique visual effect. Some of the more common include:

– Magic Eye autostereograms

– Pace autostereograms

– Microstereograms

– Fringe autostereograms

– Chromostereograms.

Each type has its own particular method for viewing and produces a different style of 3D scene. However, the basic principle behind all autostereograms is the same – the use of repeating patterns to create multiple layers of images that can be fused together by the brain into a single 3D scene. With practice, anyone can learn to view these amazing illusions and experience the depth and beauty that they offer.

What is a stereogram:

A stereogram is a two-dimensional image which can be viewed in three dimensions. They are created by encoding depth information into the picture, usually by means of different intensities of color or shades of gray. When viewed correctly, the image will appear to pop out of the screen.

Stereograms were first developed in the late 1800s as a way to create three-dimensional images without using special glasses or equipment. However, they did not become popular until the 1980s when they began appearing in magazines and posters. Today, stereograms are widely used for advertising and amusement purposes.

There are several different types of stereograms, but the most common is the depth map stereogram. This type of stereogram consists of a two-dimensional image with a hidden three-dimensional object. When viewed correctly, the object will appear to pop out of the screen.

How to see stereogram:

Stereograms work by fooling your eyes into seeing 3D images from flat, 2D patterns. In order to see the hidden image in a stereogram, you have to focus on it and ignore the pattern around it.

Different people will find different techniques useful – so you’ll have to experiment with each one to find the method that works best for you. It may also help to tilt your head slightly while viewing.

3-step depth map autostereogram:

This type of depth map autostereogram consists of a single image which can be viewed in three dimensions without any special equipment or training. The following example shows Albert Einstein’s famous formula for the theory of relativity: E=MC^2 (Einstein’s equation).

The best way to view this stereogram is by focusing on the ‘E’ in Einstein and ‘^2’, then shifting focus to the right. This should allow you to see the hidden image, which appears to be coming towards you through space. If the hidden 3D object does not appear clear at first, try looking away from it. When your eyes refocus on it, it should pop into clarity. The more blurred or out-of-focus images are in the following examples, the greater your distance should be when looking at them.

To view the following autostereograms, simply click on them. They will open in a new window where you can zoom in and out as needed.

Depth map autostereogram of 3d object:

This stereogram shows a simple three-dimensional object hidden in a two-dimensional image. When viewed correctly, the object will appear to pop out of the screen.

To view this stereogram, focus on the red dot in the middle of the picture. The hidden 3D object will then appear to come towards you from behind the screen. If it does not appear at first, try looking away from it and then refocusing on the dot.
