![]() In this type of autostereogram, every pixel in the image is computed from a pattern strip and a depth map. The well-known Magic Eye books feature another type of autostereogram called a random dot autostereogram, similar to the first example, above. ![]() When viewed with proper vergence, the repeating patterns appear to float above or below the background. The simplest type of autostereogram consists of a horizontally repeating pattern with small changes throughout that looks like wallpaper. Individuals with disordered binocular vision and who cannot perceive depth may require a wiggle stereogram to achieve a similar effect. The optical illusion of an autostereogram is one of depth perception and involves stereopsis: depth perception arising from the different perspective each eye has of a three-dimensional scene, called binocular parallax. Viewing any kind of stereogram properly may cause the viewer to experience vergence-accommodation conflict. The 3D scene in an autostereogram is often unrecognizable until it is viewed properly, unlike typical stereograms. Autostereograms use only one image to accomplish the effect while normal stereograms require two. On the downside, it hasn’t been updated for a while, so you may encounter several compatibility issues on newer operating systems.The top and bottom images produce a dent or projection depending on whether viewed with cross- ( ) or wall- ( ) eyed vergence.Īn autostereogram is a two-dimensional (2D) image that can create the optical illusion of a three-dimensional (3D) scene. Bottom lineĪll in all, Stereogram Creator proves to be a straightforward application that comes with several handy features for helping you generate stereograms. Stereogram Creator gives you the possibility to check out how the final stereogram looks like and save it to BMP or JPG file format, while allowing you to adjust the JPG quality. ![]() Preview the results and export the photos If you can’t understand several parameters, such as minimum and maximum 3D depth, separation and observation distance, you can have a look at the notations that are revealed in the main menu. Several tweaking parameters enable you to adjust the blur intensity (light, medium, heavy or none), alter the dot intensity by adjusting the built-in slider, opt for different oversampling levels, as well as adjust the observation distance, enter the maximum and minimum 3D depth, as well as provide details about the separation distance, DPI, and size. ![]() What’s more, you can select the stereogram type, namely fast random dot, textured random dot, textured image or colored dot. The tool gives you the possibility to add JPG or BMP files, and they can be imported using browse options, as there’s no support for drag and drop. Stereogram Creator allows you to import two photos from your computer: one is used for the depth map, while the other represents the mask/texture map. There’s no support for a help manual that could give rookies a change to understand how the application works so playing with the built-in parameters is the only solution in order to get familiarized with the stereoscopy concepts. You can check out the results of your stereoscopy tweaks in a dedicated window. Stereogram Creator sports a clean design and integrates all of its configuration settings into a single panel. You can run it without administrative privileges and copy it on any USB flash drive or other devices so you can easily carry it with you. What’s more, the program doesn’t write any entries in your Windows registry and store configuration data. You can open the utility by simply running the EXE file. The portability mode brings some advantages to your system. Stereogram Creator is a lightweight Windows application designed specifically for helping you create stereograms by enhancing the illusion of depth in images.
