Volumetric display from Voxon
Voxon has been showing off it’s Voxon VX2 VLED technology to create interactive volumetric holograms. It costs $6,800 so it’s definitely not cheap.
It’s likely using a high rpm spinning panel to generate the image which means that dampening the sound of the spinning array, keeping the display carefully synced to avoid pixel drift, and are some of the primary engineering concerns. They do provide a Unity and Blender SDK which is interesting.
Here’s a version of Doom playing on the volumetric display
Reminds me of the fellow that re-created the projector from Riven using a similar method.
