Google Is Building A New Foveation Pipeline For Future XR Hardware

Google's R&D arm, Google Research, recently dedicated some time and resources to discovering ways to improve the performance of foveated rendering. Foveated rendering already promises vast performance improvements compared to full-resolution rendering. However, Google believes that it can do even better. The company identified three elements that could be improved, and it proposed three solutions that could potentially solve the problems, including two new foveation techniques and a reworked rendering pipeline.

Foveated rendering is a virtual reality technique that uses eye tracking to reduce the amount of image quality necessary in areas covered by the peripheral vision.

The new techniques mentioned are Phase-Aligned Rendering and Conformal Rendering.

    That's a lot like how the real eye works (from a perceptual standpoint, not a physical one)

    It's both, and it's not just "a lot like." It's the whole reason foveated rendering is a thing in the first place.

    This is like looking at a cross-trainer and saying "hey, the way those thingies go up and down is a lot like how people's feet move when they run!"

    It's not nearly as mind-blowing as occlusion culling

    You must have quite a low mind-blow threshold.

    Not really. Blurring or otherwise reducing the quality of peripheral vision is a lot more understandable to non-technical types than the explanation that there is some magical black hole netherworld behind everything that is obstructing their vision.
