A light field display with a concave screen is proposed. The system sets the viewing area at the center of the system, letting observers enter the center of the system to watching 3D scene surround them. The surrounded 3D scene provides observers a feast of enhanced immersive experience.
An adaptive optimization in rendering process for multi-projectiontype light field display is proposed. The optimization smoothed the scene that away from the screen to reduce the distortion, without affecting the scene that near the screen. Comparison shows that the optimization enhanced the overall display quality of the scene.
A light field three-dimensional (3D) display with multi-projectors and a concave screen is proposed. The system sets the viewing area at the center of the concave screen, making viewers enter the center of the system to watch 3D scene around them. The surrounded 3D scene provides viewers a feast of enhanced immersive experience. The light field principle, rendering algorithm, selection of viewing area and experimental results are discussed in the letter, showing the potential of being an all-around-type immersive 3D display by employing more projectors.
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.
