3/24/2023 0 Comments Stereogram easyUnlike normal stereograms, autostereograms do not require the use of a stereoscope. ![]() A hidden 3D scene emerges when the image is viewed with the correct vergence. 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. Four types of 3-D plots are available.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. For 3D plots, you may choose to copy or save them as image, enhanced metafile, or data points in text format. The displays can be copied, saved or printed. You may drag-and-drop to open any supported file. You may also use any JPEG or BMP image as your coding pattern. Stereogram Maker provides (color or grayscale) random-dot coding patterns. You may choose optional perspective for creating stereograms with better visual effect.įor 3D data in range picture format, you may apply any linear or nonlinear function to map pixel values to actual distances. rotate, move or zoom) the 3D objects, and create a stereogram with the 3D objects in the position that you see on your screen. You may create stereograms from two types of 3D data: AutoCAD DXF files, or range pictures in JPEG or BMP format.įor 3D data in DXF format, you may manipulate (e.g. Supported depth map and pattern image file types: PNG, TIFF, JPEG, BMP, GIF, PICT, etc.Oversampling to give smooth depth levels.Center to both sides method to minimize the distortion. ![]() ![]()
