Multivox: Volumetric Display

In case you miss it, a video of the thing in operation is linked: https://youtu.be/pcAEqbYwixU

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.

Never knew this was possible. I hope some huge company with lots of resources jumps on this and drives up the resolution and price.

interesting it is different than these kinds

which I guess is the "volume" part

DOES IT RUN DOOM?! seriously

These displays use rotating mechanisms.

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.

I once considered making a spinning persistence of vision similar to this one specifically for visualizing lidar data from a spinning automotive lidar. The lidar has 128 beams and you could make a spinning array of 128 1D LED displays at exactly the same beam angles to recreate the point cloud from the lidar.

Anyway, I was too lazy to make it, but it's super neat to see that someone actually made something similar.

Whoa, the intersection of different skills necessary is incredible.

- software

- math

- 3d printing

- electronics

Very impressive.
