Abstract

Glasses-free three-dimensional (3D) displays can provide 3D perception without wearing special glasses or headgear. Compared with the two-dimensional(2D) images, super-multi-view(SMV) images for glasses-free 3D displays can provide more realistic 3D scenes for viewers. Among the existing methods, the ray-tracing technique is a main rendering approach to generate a virtual image. However, it is often very time-consuming to produce photorealistic 3D images because of backward ray-tracing computation with high sampling density. Here, a high-efficient distributed rendering method based on cloud computing technique is presented to reduce temporal redundancy for the generation of SMV images. Experimental results show the effectiveness of our proposed method. Compared with the primary methods working with a single computer, the computation time is decreased to 512 s from 1418 s to reconstruct a 50 viewpoints 3D image with 256 times of sampling, which achieves the resolution of 3840×2160.
