Paul Debevec: “Building an Interactive 360º Autostereoscopic Light Field 3D Display”

May 6, 2008 | Stuttgart, Germany

Speaker: Paul Debevec
Host: FMX/08: 13th International Conference on Animation, Games, Effects and Digital Media

This talk will present the hardware and software algorithms used to create USC ICT’s 3D display which is able to present interactive 3D graphics to multiple simultaneous viewers 360 degrees around the display. The display consists of a high-speed video projector, a spinning mirror covered by a holographic diffuser, and FPGA circuitry to decode specially rendered DVI video signals rendering up to 5,000 frames per second. The display can show both interactive OpenGL graphics using a custom vertex shader as well as 3D photographic imagery of real objects and people. To motivate the design of the display,the talk will describe a selection of other 3D projection techniques as well as related work in our laboratory for spinning-mirror-based multiview image acquisition. It will conclude by presenting future directions for advancing the capabilities of the display.
