Realistic Volumetric 3D Display Using Physical Materials

ABSTRACT Conventional swept volumetric displays can provide accurate physical cues for depth perception. However, the quality of texture reproduction is not high because these displays use high-speed projectors with low bit depth and low resolution. In this study, to address this limitation of swept volumetric displays while retaining their advantages, a new swept volumetric three-dimensional (3D) display is designed using physical materials as screens. Physical materials are directly used to reproduce textures on a displayed 3D surface. Further, our system can achieve hidden-surface removal based on real-time viewpoint tracking.
