Realistic 3D Swept-Volume Display with Hidden-Surface Removal Using Physical Materials

Conventional swept-volume displays can provide accurate physical cues for depth perception. However, the corresponding texture reproduction does not have high quality because such displays employ high-speed projectors with low bit-depth and low resolution. In this study, to address the limitation of swept-volume displays while retaining their advantages, a novel swept-volume three-dimensional (3D) display is proposed by incorporating physical materials as screens. Physical materials such as wool, felt, and so on are directly used for reproducing textures on a displayed 3D surface. Furthermore, we introduce the adaptive pattern generation based on real-time viewpoint tracking to perform the hidden-surface removal. Our algorithm leverages the ray-tracing concept and can run at high speed on GPU.
