Stereograms have been my thing ever since I first figured out how they work some 15 years ago. I went through several rounds of re-invigorated interest, each time developing my technique a bit further. Initially, it was random dot stereograms, which quickly moved on to those with basic background images. Then I figured out how to map textures onto the 3D shapes and enhance their contours. All of these had been done before, but in my latest round I think I have come up with something original – nothing revolutionary, or even surprising, but something I haven’t come across anywhere else yet: the Wireframe Stereogram.
This new kind of stereogram grew out of two separate ambitions I had. The first was to create paintable stereograms – images that can be transferred onto canvas with traditional painting techniques. The second was to simplify the stereograms so much that they can be generated on the fly, fast enough to respond to a user’s input in an interactive display. And the result turns out to have a third benefit, too: a simple wireframe stereogram seems to be easier to fuse than other types, which apparently helps stereogram novices to see the 3D effect.
I may write about just how all this came about some other time. For now, here’s a first example of a basic wireframe stereogram – a design I used for a Season’s Greetings card recently.
