Abstract

We propose a novel method of foveated rendering for virtual reality, targeting head-mounted displays with large fields of view or high pixel densities. Our foveation method removes motion-induced flicker in the periphery by aligning the rendered pixel grid to the virtual scene content during rasterization and upsampling. This method dramatically reduces detectability of motion artifacts in the periphery without complex interpolation or anti-aliasing algorithms.
