Reality and Surreality of 3-D Displays: Holodeck and Beyond

摘要

Most 3D displays are really just 3D models projected on 2D devices. Such 2D views sample key features of human vision processing of 3D scenes, via techniques such as converging lines and hidden surfaces, to depict relative depth. Yet, human vision actually processes more information from 3D scenes than can be captured by 2D sensors or presented on 2D displays. Approaches to true 3D and their applications will be reviewed. The Holodeck of science fiction will be examined for ultragrand technical challenges. Beyond the surreal concept of the Holodeck is the reality that significantly better 3D display systems are possible.
