Abstract

Virtual Reality has hit the consumer market with affordable head-mounted displays. When using these, it quickly becomes apparent that the resolution of the built-in display panels still needs to be highly increased. To overcome the resulting higher performance demands, eye tracking can be used for foveated rendering. However, as there are lens distortions in HMDs, there are more possibilities to increase the performance with smarter rendering approaches. We present a new system using optimizations for rendering considering lens astigmatism and combining this with foveated rendering through eye tracking. Depending on the current eye gaze, this delivers a rendering speed-up of up to 20%.
