Abstract

Super multi-view (SMV) three-dimensional (3D) display can off er immersive 3D viewing effects, but the rendering and synthesis process of massive viewpoint images poses significant challenges to real-time Performance. In this paper, a real-time rendering method of backward ray tracing in SMV display is proposed. According to viewpoint alloca-tion matrices and sub-pixel physical coordinates, rays are traced backward from viewpoint positions to 3D scenes, enab-ling real-time rendering directly on the synthetic image at the sub-pixel level. The results indicate that while maintaining consistent display quality, the rendering frame rate remains above 35 FPS even with an increasing number of viewpoints. The proposed method avoids information redundancy in the rendering synthesis process, achieving a rendering speed im-provement of 5 Orders of magnitude compared to traditional sequential viewpoint rendering methods. Thus, it provides a promising avenue for achieving super multi-view dynamic 3D display.
