It's Poxel

Another volumetric display! This one does away with the wildly spinning arrays of LEDs, instead using projection mapping onto a point cloud etched inside a block of glass. It has a resolution of around 38000 points - not anyone's idea of HD, but enough for playable games (if you're generous with your definitions of 'playable' and 'games'). The showreel demos all come from Multivox (https://github.com/AncientJames/multivox ), the codebase that handles my spinning displays. There's a new device driver for the new setup, but the demo code is unchanged. The stack of optomechanical stages was rescued from a local lab clearout some years ago. The next step for this project would be to get rid of that, build a solid mount in a nice housing, and perform the alignment in software. I'm not the first person to do this - a group at Columbia University built one in 2006 https://cave.cs.columbia.edu/Statics/publications/pdfs/Nayar_TR06.pdf
