Build Your Own 3D Volumetric Display for Under $50
Seriously, are we ever going to get the cool, 3D displays sci-fi has teased us with for decades? What I want is R2-D2’s holoprojector or the computer interface shown in Minority Report, but all I ever get is pixels packed more tightly together on a flat, opaque panel. Come on! We can send people to the Moon, but we can’t make a practical 3D display for home use?
Whine as I may, that is unfortunately the case. But that doesn’t stop hackers from making some pretty cool 3D displays in their basements, even if they are low-resolution and impractical for general use. A nice example of such a project comes from YouTuber “Embedded in my Basement.” He built a mechanical volumetric display for exploring 3D models in real 3D space.
