Depth based foveated rendering for display systems

A computer-implemented method, the method being performed by a display system of one or more processors, and the method comprising:

• determining a fixation point of a user's eyes;
• obtaining location information associated with a first virtual object to be presented to the user via a display device configured to output light with a plurality of levels of wavefront divergence, wherein different levels of wavefront divergence correspond to different distances from the fixation point of the user's eyes;
• obtaining a resolution-modifying parameter of the first virtual object;
• identifying, based on the location information and the resolution-modifying parameter of the first virtual object, a particular resolution at which to render the first virtual object, wherein the particular resolution is based on a resolution distribution specifying resolutions for corresponding distances from the fixation point, wherein identifying the particular resolution comprises associating different resolutions with different levels of wavefront divergence, wherein the distances from the fixation point correspond to different angular distances and depths, wherein a field of view of the user is separated into a plurality of portions based on the resolution distribution, wherein each portion encompasses a respective range of angular distances from a center of the field of view, and wherein, for a particular depth or range of depths, each portion is assigned an associated resolution at which to render virtual content;
• and
• causing presentation to the user, via the display device, of the first virtual object rendered at the identified resolution by outputting light from the display device with a level of wavefront divergence associated with the identified resolution.

Non-transitory computer storage media storing instructions that when executed by a display system of one or more processors, cause the one or more processors to perform operations comprising:

• determining a fixation point of a user's eyes;
• obtaining location information associated with a first virtual object to be presented to the user via a display device configured to output light with a plurality of levels of wavefront divergence, wherein different levels of wavefront divergence correspond to different distances from the fixation point of the user's eyes;
• obtaining a resolution-modifying parameter of the first virtual object;
• identifying, based on the location information and the resolution-modifying parameter of the first virtual object, a particular resolution at which to render the first virtual object, wherein the particular resolution is based on a resolution distribution specifying resolutions for corresponding distances from the fixation point, wherein identifying the particular resolution comprises associating different resolutions with different levels of wavefront divergence, wherein the distances from the fixation point correspond to different angular distances and depths, wherein a field of view of the user is separated into a plurality of portions based on the resolution distribution, wherein each portion encompasses a respective range of angular distances from a center of the field of view, and wherein, for a particular depth or range of depths, each portion is assigned an associated resolution at which to render virtual content;
• and
• causing presentation to the user, via the display device, of the first virtual object rendered at the identified resolution by outputting light from the display device with a level of wavefront divergence associated with the identified resolution.
