Toward low-computation light field displays by foveated rendering

Abstract

Recently, glass-free light field displays of multi-layer architecture have gradually entered the commercial stage. However, for near-eye displays, light field rendering still suffers from expensive computational costs. It can hardly achieve an acceptable framerate for real-Time displays. This work develops a novel light field display pipeline that uses two gaze maps to reconstruct display patterns of foveated vision effect. With the acceleration of GPU and the emerging eye-Tracking technique, the gaze cone can be updated instantaneously. The experimental results demonstrate that the proposed display pipeline can support near-correct retinal-blur with foveated vision and high framerate at low-computation.
