@ancientjames@mastodon.social @commanderred@chaos.social I see. Just thought by randomly displacing the pinhole origins slightly, you would sacrifice some view angle (or would need to reduce the resolution a bit) and introduce more noise to the overall picture but at the same time might reduce some of the aliasing artifacts arising from the ordered hole placement.
No idea though if the raspi could calculate the displaced offsets fast enough in its shader though hashes or a big enough table.

@foerterer@mastoart.social It might be easier to visualise by imagining there is only one hole, and it's being scanned in front of the screen like a crt raster. Wherever it is at any instant, there is a unique image being generated on the screen behind it. That image is shining out through the pinhole, as though it's the lens of a projector. The result is as if there are thousands of projectors in a grid, making up the image. Each one looks different depending on where your eye is, which is why it's 3D.
