Screen-space ambient occlusion for light field displays

Abstract

In this paper, we discuss the challenge of generating the screen-space ambient occlusion (SSAO) visual effect on the state-of-the-art HoloVizio light field display. We detail the main features of modern SSAO techniques that are currently being applied during visualization on conventional 2D displays, and describe difficulties that potentially can appear when implementing this visual effect on 3D light field or similar systems. The main contribution of this paper is our own modification of the SSAO algorithm for light field displays. The paper also includes suggestions on the possible ways to improve its visual quality and performance.
