Years ago I created and posted a handful of stereograms, and then I started a series of tutorials to share how I made them. Part I described how to create a background pattern or texture, and Part II described how to create a distance mask render or depth map. But I never finished the series of tutorials and completely left out this part, Part III.

I didn’t get into it because by that time I was on a new computer and no longer had access to the app I used to create my stereograms. It was a free Windows program, really obscure, and I had just migrated everything over to Mac. I couldn’t find another program like it; I couldn’t even find where I’d originally gotten the program itself. So it seemed pointless to write about software other people couldn’t get themselves either.

Well … now I’m blogging again, and there are apps everywhere! The will and the way bring you this:

Back then, finding a tutorial on this was like finding a needle in a haystack. Today, it’s as simple as taking your texture:

…and your depth map:

…uploading them to a free and easy online stereogram maker like this one, and combining them to make the stereogram you see above.

See how easy that was? So sorry you had to wait years and years and years to learn this!
