Adaptive Foveated Ray Tracing Based on Time-Constrained Rendering for Head-Mounted Display

Ray tracing-based rendering creates by far more realistic images than the traditional rasterization-based rendering. However, it is still burdensome when implemented for a Head-Mounted Display (HMD) system that demands wide field of view and high display refresh rate. Furthermore, presenting high-quality on HMD screen, sufficient number ray sampling should be carried out per pixel to alleviate visually annoying spatial temporal aliases. In this paper, we extend recent selective foveated tracing technique Kim et al. [1], propose an improved real-time realizes effect classic Whitted-style system. particular, combining hardware-based acceleration time-constrained scheme, show fast possible well suited human visual systems.
