Reminds me that there are limitations to volumetric displays—namely that, since you have no idea where the viewer is located, there is no backface culling you can perform. So it seems to work best for "cutaway" views.
I'd like to see one in person. Might be "magical" — the video only kind of hints at this.
For example imagine a spinning display like those of the article but somehow tuned so that they are only visible when exactly head on. In that case, you know where the observer is: right in line with the screen. So you can have backface culling; as the display spins you render all 360 (or however many) viewpoints.
Now granted, this doesn't deal with how high or low the observer is. We'd need to find another solution for that.
I don't understand: doesn't defeat the purpose of a volumetric display (seeing what is displayed from multiple point of view) ?
This ones does not: https://www.youtube.com/watch?v=wrfBjRp61iY
Volumetric display in the video above uses static projector whose pixels light up etchings inside solid glass.
oh wow yeah I've seen a lot of this channel's work before the lego display, the CV fiber optic bundle display
> [I]nside the dome the air quickly ends up rotating at the same rate as the rest of the mechanism. It's reaching its design speed with the motor at less than half duty cycle. Even if it were practical to make the whole thing airtight, it doesn't solve a problem that I currently have. The sound it makes doesn't come from inside the dome but from the motor in the base.

My intuition says "change the sphere to a cylinder", because then we can minimize how much air could be passing around the sides and top of the display-rectangle, potentially curling around and causing turbulence and noise.
However, that introduces a new issue of visibility: Big flat surfaces have different glare/reflection problems than a spheroid does. It may become harder for the user to see clearly, whether from external glare or from internal reflections in a dark room. What if the top face of the glass cylinder was very slightly curved outwards, to avoid the worst-case scenario where you just can't look down into the device from certain angles? Depending on the refractive index of the glass, it could just be a thicker top, so that it doesn't create dead-space on the inside.

Very impressive.
The solid state ones are cool! The real mystery there is how the pixel volume was manufactured -- it doesn't seem like something easily DIY'd
Shameless plug, I made a similar thing but for bike wheels!
Anyway, I was too lazy to make it, but it's super neat to see that someone actually made something similar.

Uh, I get the former but why the latter?
I mean, I think it's SUPER cool and would not mind one sitting on my desk.
But from a product standpoint...? It doesn't scale well in size, resolution or refresh rate.
VR is pretty much better if you want a the kind of immersion I think you'd be looking for, and even selling that is hard.

which I guess is the "volume" part
