Autostereoscopic Rendering of Multiple Light Fields

Abstract

Light fields were introduced a decade ago as a new high-dimensional graphics rendering model. However, they have not been thoroughly used because their applications are very specific and their storage requirements are too high. Recently, spatial imaging devices have been related to light fields. These devices allow several users to see three-dimensional (3D) images without using glasses or other intrusive elements.This paper presents a light-field model that can be rendered in an autostereoscopic spatial device. The model is viewpoint-independent and supports continuous multiresolution, foveal rendering, and integrating multiple light fields and geometric models in the same scene.We also show that it is possible to examine interactively a scene composed of several light fields and geometric models. Visibility is taken care of by the algorithm. Our goal is to apply our models to 3D TV and spatial imaging.
