First attempt at reconstructing a raster image by spinning a rigid object
I’ve been hesitant to put full images on my pinhole zoetropes because of crowding. The holes need to be spaced sufficiently to avoid too much interference. Because of this, until now I’ve programmed the animations around dotted lines.
But I recently realized that for the parts of a design that aren’t animated, I can distribute each dot’s viewing tunnel at any angle around the top’s spin axis, vastly reducing any crowding. By rotating the tunnel’s position and orientation together, its dot still appears in the intended image position when the top spins.
This pumpkin was my first attempt at generating the dot pattern directly from a raster image, with additional logic to sharpen the edges. I tried adding animations alongside the image, but the small form factor made it too busy. Without an animation, it isn’t technically a zoetrope. Regardless, the simplicity is part of the charm for this model, so I’m releasing it as a pure static-image persistence-of-vision illusion. I haven’t found a great term for this kind of illusion yet.
My next device, a dragon egg, is well underway. Its taller shape gives me room for both a raster-based dragon image and an animated fire-breathing effect. Still gotta iron out the kinks, but it's promising.
In the meantime, enjoy this Halloween print:
