Pepper's Cone: An Inexpensive Do-It-Yourself 3D Display
"Our 3D display consists of (a) an iPad, a thin hollow plastic cone, and a rotatable base. The nickel at the base provides stability. (b-c) As the user rotates the display, the system renders a perspective-correct image for their point of view that gives a convincing impression of a 3D object suspended inside the cone. This provides a very simple way of interactively examining a 3D scene for a fraction of the cost of alternative volumetric or light field displays and doesn't require the use of special glasses. (d) In addition, the system can be extended to produce correct binocular cues by incorporating stereoscopic rendering and glasses."
