Abstract:In this paper, we propose a high‐efficient rendering method based on the backward ray‐tracing technique to generate the annular sector elemental image array (ASEIA), which can form an ideal annular viewing zone for tabletop integral imaging 3D display. In the rendering process, different pixels in each annular sector elemental image are associated with different viewpoints by the backward rays in one rendering step. Therefore, the ASEIA can be obtained directly without capturing single‐viewpoint images from al… Show more
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.
