Wow. If you try to do it on a large scale it would be somewhat dangerous too, I suspect.

- logfromblammo 9y agoArticle mentioned that other volumetric displays could cut off your fingers if you put your hand inside the volume, but heavily features use of fingers in the pictures to show scale. This only requires enough power to push a tiny speck of dust around. If you had a precise enough means of determining the position of a particle, and a precise enough means of painting it with visible light, you could rely on Brownian motion to trace out your image. You project the color and intensity of whatever voxel the particle happens to be in at that moment, and the dust scatters that light everywhere. But if you can force the particle to trace out a specific path instead of a random one, you can make it walk through all the voxels in sequence, and paint your whole volume reliably. The problems with scaling up are controlling multiple particles at once without making any of them occlude the others from the perspective of the painter lights and pusher lasers. One speck can only travel through so many voxels in the time required to paint one frame. And the more specks you have, the more likely it is that one that is supposed to display transparent will be occluding one that is supposed to be colored. The image would get "foggy".
