Abstract
Methods and systems for depth-based foveated rendering in the display system are disclosed. The display system may be an augmented reality display system configured to provide virtual content on a plurality of depth planes using different wavefront divergence. Some embodiments include monitoring eye orientations of a user of a display system based on detected sensor information. A fixation point is determined based on the eye orientations, the fixation point representing a three-dimensional location with respect to a field of view. Location information of virtual objects to present is obtained, with the location information indicating three-dimensional positions of the virtual objects. Resolutions of at least one virtual object is adjusted based on a proximity of the at least one virtual object to the fixation point. The virtual objects are presented to a user by display system with the at least one virtual object being rendered according to the adjusted resolution.
