Abstract

Three dimensional (3D) displays are part of a growing market. These 3D displays are often seen in home entertainment and film industries. The most common three dimensional techniques require the use of glasses with special lenses to add the effect of “depth” in an animation. This project attempts to prove that a true three dimensional display can be made using low cost and accessible materials. The display is made from 625 Light Emitting Diodes (LEDs) on a Peggy 2LE LED matrix display. The Peggy 2LE board is spun around 15 Hz and held tight between two cylindrical bearings. Blender, an open source animation software, in tandem with Mathematica, a technical computing application, was used to convert three dimensional animation objects into a precise sequence of LED flashes. The sequence of abrupt LED flashes over the sweeping volume of the LED matrix created the appearance of a true three dimensional object. The three dimensional display created in this project had almost no loss of occlusion, enabling the display to be viewed with near perfect perspective at all angles without the need of special glasses. This report will include an introduction explaining how volumetric displays work as well as what other 3D technologies exist today. Then a generalized methodology explaining how the project was put together and finally the results of the project will be discussed.
