Figure 1: A 3D object shown on the display is photographed by two stereo cameras (seen in the middle image). The two stereo viewpoints sample the 360 • field of view around the display. The right pair is from a vertically-tracked camera position and the left pair is from an untracked position roughly horizontal to the center of the display. The stereo pairs(More)
While a great deal of computer generated imagery is modeled and rendered in 3D, the vast majority of this 3D imagery is shown on 2D displays. Various forms of 3D displays have been contemplated and constructed for at least one hundred years [Lippman 1908], but only recent evolutions in digital capture, computation, and display have made functional and(More)
We describe a set of rendering techniques for an autostereoscopic light field display 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(More)
We present a novel compression method for fixed viewpoint re-flectance fields, captured for example by a Light Stage. Our compressed representation consists of a global approximation that exploits the similarities between the reflectance functions of different pixels, and a local approximation that encodes the per-pixel residual with the global(More)
