I got a live demo of this at a conference a few years back. There was a line to see the demo, so I first waited while others did it. They first showed the full resolution image, then enabled the foveated rendering. The latter looked terrible - a tiny patch of hires imagery and a massive blur for everything else.
When it was my turn, they started with the full resolution image. I was waiting for them to enable the foveated rendering - until they told me it was already running. I could not tell at all that it was not all rendering at full resolution. Really impressive.
The main presenter mentioned that the optic nerve/brain processing 'shuts down' for up to 40ms during a saccade, so they have that long to render the small region at full resolution between the time when your eye has its new target and the optic nerve comes back on line.
- soared 11y agoI'm so glad to hear this! Do you know of any progress since then? That very closely reminds me of my first time trying VR (last week). I sat and watched on the 2D monitor someone else doing it, and thought it looked incredibly stupid. Then I put on the headset..
- martinpw 11y agoI don't know of any explicit details of progress, but everyone I've mentioned it to in the VR space nods knowingly when I mention it, so I take that to mean that it is an area of active research and development.
