Smart Rendering for Virtual Reality

[gyg]

"Researchers from Intel have been working on new methods for improving the rendering speed for modern wide-angle head-mounted displays like the Oculus Rift and Google Cardboard. Their approach makes use of the fact that because of the relatively cheap and lightweight lenses the distortion astigmatism happens: only the center area can be perceived very sharp, while with increasing distance from it, the perception gets more and more blurred. So what happens if you don't spend the same amount of calculations and quality for all pixels? The blog entry gives hints to future rendering architectures and shows performance numbers."
