Abstract:
While a great deal of computer generated imagery is modelled and rendered in three dimensions, the vast majority of this 3D imagery is shown on two-dimensional displays. Various forms of 3D displays have been contemplated and constructed for at least one hundred years, but only recent advances in digital capture, computation, and display have made functional and practical 3D displays possible. In this thesis, I propose several designs that overcome some of the classic limitations of 3D displays. The displays are: autostereoscopic, requiring no special viewing glasses; omnidirectional, allowing viewers to be situated anywhere around it; and multiview, producing a correct rendition of the 3D objects with correct horizontal parallax and vertical perspective for any viewer around the display.

The first display prototype utilizes a spinning anisotropic mirror to distribute frames from a high-speed video projector to different viewers. Unfortunately, as the size and mass of the mirror increases, it becomes increasingly difficult to maintain a stable and rapid rotation speed. The second 3D display form has no moving mechanical parts, provides interactive content, and scales to large format displays. The key insight is that a large array of closely stacked projectors aimed at a stationary anisotropic screen is optically equivalent to a single high-speed projector aimed at a rotating anisotropic screen. Both types of display utilize new algorithms based on geometry and light filed based rendering. Applications for these displays include life-size interactive virtual characters, 3D teleconferencing, and time-offset conversations with 3D subjects.
