Depth based foveated rendering for display systems
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.
Generating a volumetric representation of a capture region
A method includes displaying, on a display, a representation of a physical environment and a computer-generated object. The method includes generating a three-dimensional (3D) point cloud associated with the representation of the physical environment. The method includes obtaining depth information characterizing the physical environment. The method includes obtaining a capture event associated with a capture region within the representation of the physical environment. The capture region includes a portion of the computer-generated object. The method includes, in response to obtaining the capture event, disambiguating a group of points from the 3D point cloud, and generating, based on a function of the depth information and the group of points, a volumetric representation of the capture region. The group of points satisfies a spatial threshold with respect to the capture region. The volumetric representation includes a volumetric representation of the portion of the computer-generated object.

Multi-perspective stereoscopy from light fields
Methods and systems for generating stereoscopic content with granular control over binocular disparity based on multi-perspective imaging from representations of light fields are provided. The stereoscopic content is computed as piecewise continuous cuts through a representation of a light field, minimizing an energy reflecting prescribed parameters such as depth budget, maximum binocular disparity gradient, desired stereoscopic baseline. The methods and systems may be used for efficient and flexible stereoscopic post-processing, such as reducing excessive binocular disparity while preserving perceived depth or retargeting of already captured scenes to various view settings. Moreover, such methods and systems are highly useful for content creation in the context of multi-view autostereoscopic displays and provide a novel conceptual approach to stereoscopic image processing and post-production.
