IMO, the holy grail of 3d dithering is yet to be achieved. runevision's method does not handle surfaces viewed at sharp angles very well. I've thought a lot about a method with fractal adaptive blue noise and analytic anisotropic filtering but I don't yet have the base knowledge to implement it.

This really is a fantastic video. I don't think I'd considered many of the ideas behind dithering before seeing how it could be extrapolated to this degree.

The video ends in a place where I suspect even further advances could still be made.

		There's a follow up video with variations of the technique (some of them with color) demonstrated in a game: https://www.youtube.com/watch?v=EzjWBmhO_1E But yes, there's still the issue of oblique angles looking different that still remains open AFAIK.

Very cool! The dither is no longer in screenspace though, which kills the retro charm.

		Fair point, though I think that when it's low rez enough, it becomes less apparent that it's not in screenspace, and it gets closer to a retro look: https://youtu.be/EzjWBmhO_1E?t=102
