Perceptual Model based Surface Tessellation for VR Foveated Rendering

Abstract

With the rapid development of VR head mounted display, VR scenes need to be presented at higher resolutions and higher frame rates. Foveated rendering is an important technique to balance computing resource demand and user satisfaction. In this paper, we propose a perceptual model based foveated rendering. By culling the imperceptible region and adaptively adjusting the tessellation levels based on visual sensitivity, we improve the rendering performance in real-time rendering frameworks.
