Parameterization of sharable display area to reproduce appropriate glasses-free tabletop 3-D images

Abstract

This paper proposes an approach to create appropriate virtual 3-D scenes to be shared with many people on a novel glasses-free table-top 3-D display. For maintaining appropriate omni-directional observation, the virtual objects must be situated in a certain volume. We first analyze and parameterize the volume derived from the geometrical configurations of the 3-D display. Then we simplify the volume as the primitive shape of a sphere. The volume visualizes the restrictions in the 3-D scene creation and helps content creators concentrate on their creative work using their favorite tools.
