#Make a stereogram code

To correct this I paired every point of the depth map (not only the white one) in order to come back to the base shifting amount after the end of the star.Д¬ode: (This code is the previous one quickly modified after the help of Neil Slater so it's not clean yet. What I didn't get is that because RDS are made by repeated patterns, shifting these pixels also create an opposite shifting with next patterns creating an other star of the opposite depth. What was wrong in my approch is that I only shift pixels that should create the star. To create 2 images stereograms you need to shift pixels of one image to make the depth illusion. The problem 'I can see on the result 2 objects, 1 star 'close' to me and an other star 'far' from me' is due to the fact that I get the wrong approach when I try to generalize my understanding of stereograms made with 2 images to stereograms using repeated pattern. Point we make the shifted pixel equal to the other one Here we fill the window with the pattern. If you see four squares, move the image farther. Very slowly move the image away from your face until the two squares above the image turn into three squares. Focus as though you are looking through the image into the distance. List_linked_point.append(, ])Дef display_stereogram(screen, s_width, pattern, p_width, linked_points): Hold the center of the printed image right up to your nose. In this function we link each pixel in white in the depth map with theД¬oordinate of the shifted pixel we will need to create the illusion I didn't clean it yet) import os, sysДef get_linked_point(depthmap, d_width, d_height, sep): Note: I have tried with different size on shift and pattern and it doesn't seem to change anythingД¬ode: (Tell me if you need other part of the code or some comment about how it work.

#Make a stereogram how to

Maybe the problem is my poor english or understanding of what I've read but I will appreciate some detailed explanations since there not that much technical explanations on the web about how to code this from scratch. I have read many things on the subject but I don't get it. And there is different possible results depending of how I focus my eyes. I put this into practice with this depth map:Д«ut I don't understand why I can see on the result 2 objects, 1 star 'close' to me and an other star 'far' from me. From what I've understood, to create the illusion of depth, pixels are shifted so when we make them merge by changing focus the difference of shifting creates the illusion. Also IвЂ™m going to post all my experiments and write few words about that.I am trying to understand and code a python script that create a random-dot stereogram (RDS) from a depthmap and a random-dot generated pattern. This allows the image pairs to be made into scientifically useful stereoscopic images, which can be viewed as stereograms, anaglyphs, or processed into 3D. I hope it helps you a bit in exploration of Magic Depth. In picture below I added some objects and also made upper row of monkeys closer to your eyes but in 3d space they are further from camera just to tell you in that case distance from camera doesnвЂ™t matter. If you want to play with specialized apps to make MagicEye stereograms you can export Z-buffer of your scene as picture and import it to some MagicEye maker. In Blender we have InvertZBuf function and IвЂ™m trying to use that feature but it takes a lot of experiments. Make your own 3D optical illusion of depth from 3D models, text, or depth maps.

And thatвЂ™s why Persp camera produces strange effect. Stereogram Explorer is user-friendly stereogram software for creating perfect high-quality stereograms hidden 3D images, also known as Single Image Random Dot Stereograms (SIRDS) or Single Image Stereograms (SIS) known from the Magic Eye series. In perspective view objects and distance between them is getting smaller with distance from eye (camera), in MagicEye to see effect, distance between objects(pattern) should be smaller for objects closer to eye(camera). I use Ortho camera because MagicEye phenomenon is quite opposite to what we see in real perspective(camera). Real distance from camera in 3d space doesnвЂ™t matter and I use it just to see what should be closer to my eyes. Objects closer to your eyes should have smaller gaps between repetitions and for further objects gaps should be bigger. Idea is simple : make picture with patterns repeated horizontally.

#Make a stereogram manual

Whole effect you see is manual work with a lot of adjustments and renderings. I use Blender just as a tool for creating and rendering scenes. ДЄfter reading this info : IвЂ™m not sure if itвЂ™s Cross- or Parallel-view but it works.Дepth you can see is not Blender feature. First my apology for long time without response - I had a lot of work.ДЄnother masterpiece from the same artist as in my first post.
