Embodiment Construction
[0107] Rendering virtual content for augmented and virtual display systems is computationally intensive. Among other things, computational intensity may use undesirably large amounts of memory, result in high latency, and / or may require the use of powerful processing units, which may have high cost and / or high energy consumption.
[0108] In some embodiments, methods and systems conserve computing resources, such as memory and processing time, by reducing the resolution of virtual content located at locations away from the gaze point of the user's eyes. For example, the system may render virtual content at a relatively high resolution (e.g., the highest resolution) at or near the gaze point of the user's eyes, while utilizing one or more lower resolutions for virtual content further away from the gaze point. . The virtual content is presented by a display system that can display the virtual content at multiple different depths (e.g., multiple different depth planes, such as t...

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.
