Figure 1: The standard approach to the design of automultiscopic 3D displays attempts to cover the angular range of all viewer positions. However, there are usually unavoidable trade-offs between the angular range and resolution of such displays. Therefore, an application of automultiscopic technology to real-sized 3D cinema, where viewing range is usually very wide, would typically involve poor spatial/angular resolution (left), or a restricted range of screen distances. In contrast, we suggest a 3D display architecture that only presents a narrow range of angular images across the small set of viewing positions of a single seat, and replicates the same narrow angle content to all seats in the cinema, at all screen distances (right).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
