If you don't know what a stereogram (SIS) is, or how to see them, you can read the Wikipedia or my website or ask Google. Autostereograms were very popular in the '90s. In each image, there is a 3D object that can only be viewed by looking at the image a certain way, as if the screen was transparent and you looked at the wall behind it. LicenseĬopyright 2010-2022 by Charles L.G. This site allows to generate your own stereograms, based on one or two lines of text and a selected background pattern. An autostereogram (also known as Magic Eye) is a 2D image designed to create the illusion of 3D. Just install thin, and execute:īrowse to localhost:3000 and everything should be happy. is a Rack file for using thin to run a temporary server on localhost:3000. Sometimes when uploading a pattern or depthmap it is added more then once.Īpparently the Canvas and File API's have security problems if they aren't being hosted off of a webserver. Android (not sure on the file upload, but the autostereogram renders on my Nexus One).I know it at least renders the autostereogram in: CrossbrowserĪs this was a proof of concept hack, I didn't really focus much onĬross-browser testing. Here, you can share your creation with the world, as well. They are perfect to surprise your friends. My implementation is a very close translation of his C into javascript as my previous implementation of the algorithm left much to be desired in terms of image clarity. Here you can design and create your own stereograms online freely. I copied liberally from tutorials on local file upload, canvas and this description on how to create autostereograms. My javascript was pretty rough when I wrote it, and I'm a bit embarrassed by some of the code, but we all have to learn sometime. Clicking on the canvas will display the depthmap. Note that some of the depthmaps are encoding max depth as 0 instead of 255, so if it looks like the image is inside out, just use the invert depthmap checkbox. This is why reloading the page ditches any patterns or depthmaps you "uploaded". If you are a programmer (or a careful person), you will find that some programs or software will explain the program implementation or service architecture. ![]() The neat thing about the file upload buttons is they aren't actually uploading to the server, just loading the image you select into the page. This is a cool text generator that converts text to ASCII text. Using the radio buttons at the base of the page you can select which depthmap you want to render, and with which pattern to embed the stereogram in the tiling. It's that easy You can also use custom patterns or custom masks created by your self (this is for advanced users). Basically it generates a "Magic Eye" image out of a black and white depthmap and a pattern to replicate. How to use the online builder Just select a mask and a pattern of your choice and then you are ready to generate your own stereogram. I wrote this last summer as a quick hack to play around with javascript, specifically the new canvas and in browser uploading features.
