Abstract

Light field 3D display is a glasses-free 3D display that samples and reconstructs the light field guided by ray optics. To increase the density of the discrete viewpoints, parallax images in more than tens or even hundreds of directions should be sampled, which adds up to computation and slowdowns the generation speed of the 3D image source. In this paper, a fast generation method for 3D image source based on instancing camera rendering is proposed, which greatly optimizes the speed of the parallax image rendering process in light field 3D display. Experimental results reveal that the proposed method can generate the 4K and 8K light field 3D image sources at over 60 frames per second (fps) with viewpoints less than 160 and 80, respectively, performing at least 106% and 94% faster than the conventional non-instancing method.
