Systems and methods for foveated rendering

A method comprising, by a computing system:

• determining a focus point of a viewer based on sensor data received by the computing system;
• determining, for a current frame, a first viewing region encompassing a focus point of the viewer and a second view region excluding the first viewing region;
• determining, for the current frame, color values for the first viewing region using respective first sampling resolutions for a plurality of color channels, and color values for the second viewing region using respective second sampling resolutions for the plurality of color channels, wherein at least one second sampling resolution is lower than a corresponding first sampling resolution associated with a same color channel, and wherein at least two of the second sampling resolutions for the plurality of color channels of the second viewing region are different from each other;
• and
• outputting the color values for the first viewing region and the second viewing region of the current frame for display.

One or more computer-readable non-transitory storage media embodying software that is operable when executed to:

• determine a focus point of a viewer based on sensor data received by the computing system;
• determine, for a current frame, a first viewing region encompassing a focus point of the viewer and a second view region excluding the first viewing region;
• determine, for the current frame, color values for the first viewing region using respective first sampling resolutions for a plurality of color channels, and color values for the second viewing region using respective second sampling resolutions for the plurality of color channels, wherein at least one second sampling resolution is lower than a corresponding first sampling resolution associated with a same color channel, and wherein at least two of the second sampling resolutions for the plurality of color channels of the second viewing region are different from each other;
• and
• output the color values for the first viewing region and the second viewing region of the current frame for display.

A system comprising:

• one or more processors, and
• one or more computer-readable non-transitory storage media coupled to one or more of the processors and comprising instructions operable when executed by one or more of the processors to cause the system to:
• determine a focus point of a viewer based on sensor data received by the computing system;
• determine, for a current frame, a first viewing region encompassing a focus point of the viewer and a second view region excluding the first viewing region;
• determine, for the current frame, color values for the first viewing region using respective first sampling resolutions for a plurality of color channels, and color values for the second viewing region using respective second sampling resolutions for the plurality of color channels, wherein at least one second sampling resolution is lower than a corresponding first sampling resolution associated with a same color channel, and wherein at least two of the second sampling resolutions for the plurality of color channels of the second viewing region are different from each other;
• and
• output the color values for the first viewing region and the second viewing region of the current frame for display.
