@foerterer@mastoart.social The hole positions are unrelated to the layout of the LEDs on the panel behind. The trick that makes this thing work is that the holes are a few centimetres in front of the panel. What you see through the hole - the specific LED that's visible - is entirely view dependent, which is why each eye sees a different scene and why it's 3D. Only rarely will your eye align exactly with an LED. Most of the time it's somewhere between them. When I spoke about scanlines, it was the drum's scan.

@ancientjames@mastodon.social Thank you for your patience regarding my questions… And sorry for mixing both scanline domains in my argument. My question is: if there are 80 vertical drum holes at 48 different horizontal positions, that would allow for a theoretical overall vertical resolution of 80x48=3840 scanlines at different heights per rotation, or am I mistaken again? Perhaps it‘s the clearly visible scanlines in the initial video that confuse me. Are they perhaps due to the camera sensor readout speed?
