Sure, if you replace each pixel with a tiny light field display pixel you can do occlusion.
- mhalle 2y agoUnfortunately, that's a big challenge for a volumetric display, particularly a spinning one. There's a mass problem (heavier spinny things are more difficult than lightweight spinny things). There's also a wire problem if the elements on the spinning element are active and need to be addressed, since the wires generally need to come through the hub. If a projector is used and the spinning element is passive, then there's a tricky alignment issue. And in any case, there's a bandwidth issue, since every 3d point is now addressed by a 1D or 2D array. That's an enormous amount of the data that ultimately needs to be uncompressed by the time it hits the display hardware.
