Using swept 2D imagery - I am re-creating an experiment from USC (http://gl.ict.usc.edu/Research/3DDisplay/) to better illuminate where we're headed with volumetric display technology and how we can begin thinking about interacting with it. The display consists of an angle mirror on a rotating motor and a high-speed projector.

Background
Learned about different 3D display techniques including parallax barriers, lenticulars, re-imaging, swept persistence of vision, holograms, and non-traditional means (smoke, air, water, etc). I also learned about the binary file format of .bmp files and how to transfer binary packets over a TCP connection. I also worked with webGL to export 360 images of a 3D scene dynamically.

Audience
Anyone with eyeballs

User Scenario
Someone comes up and looks at it. They walk around the display and view the content from 360 angles. We chat about potential ways to interact with it and where we think this technology is headed.

Implementation
An angled mirror on a rotating motor. A high speed dlp projector. A resin/plexi casing.

Conclusion
Volumetric displays are very difficult to achieve and there's a lot of barriers to allow it to become mainstream. From content generation, transmission, to decoding - there are hurdles at every step that need to be overcome.
