Abstract
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.
