It uses this repeat interval to look up the color of the counterpart pixel to the left and uses its color as the new pixel's own color. For every pixel, it subtracts the shift from the width of the pattern image to arrive at a repeat interval. The next is an attempt to construct a stereogram of a cylinder manually. Unlike other 3D vision techniques (eg: hollograms). Then it consults the depth map to retrieve appropriate shift values for subsequent pixels. What is a stereogram Stereograms are special imagenes that create a very sharp illusion of 3D vision.
Create stereogram series#
It seeds the first series of pixels in a row from the pattern image. One way to accomplish this is to make the program scan every line in the output image pixel-by-pixel from left to right. Conceptually, at every pixel in the output image, the program looks up the grayscale value of the equivalent pixel in the depth map image, and uses this value to determine the amount of horizontal shift required for the pixel. Create your own autostereogram These images, known from the magic eye books, reveal a hidden 3D image.
Create stereogram how to#
The program tiles the pattern image horizontally to cover an area whose size is identical to the depth map. How To Make a StereoGram with GIMP, Blender and StereoGraph Single Image Stereograms (SIS) are two-dimensional images that seem to be three-dimensional these.

Create stereogram tv#
The easiest thing to do is take a picture of a TV screen when it is not tuned to a channel. The wikipedia article on autostereograms describes the algorithm for creating depth map based stereograms like this:Ī computer program can take a depth map and an accompanying pattern image to produce an autostereogram. To create a random dot stereogram like this, first you will need a picture of random dots. Stereograms evolved from stereo photography, in which two photographs are taken from slightly different camera.
