Fast rendering and display of light field images with a controllable lighting mechanism.

A fast light field (LF) image rendering method with controllable lighting mechanism is proposed and demonstrated. It solves the issue that previous image-based methods could not render and edit lighting effects for LF images. In contrast to previous methods, light cones and normal maps are defined and used to expand the RGBD images into RGBDNθ data, which gives more degrees of freedom to render LF images.
