Abstract: A decoding computing device determines a focus area of a view of volumetric visual content, such as a three-dimensional (3D) object or scene, and indicates the focus area in a request for compressed volumetric visual content. A server provides a depth map and an attribute atlas that includes attribute and/or texture information for the focus area that is signaled at a higher resolution than other portions of the volumetric visual content. The decoding device also applies one or more mesh simplification techniques, wherein a higher resolution mesh is used for the focus area. The textures/attributes are projected onto the mesh representations, wherein the mesh representations and projected textures are used to reconstruct the volumetric visual content. Hole filling techniques are then applied, wherein a more sophisticated hole filling technique is used in the focus area.

Abstract: Implementations of the subject technology provide determining an operating mode of an electronic device based at least in part on whether the electronic device is communicatively coupled to an associated base device. Based on the determined operating mode, the subject technology identifies a set of input modalities for initiating a recording of content within a field of view of the electronic device. The subject technology monitors sensor information generated by at least one sensor included in, or communicatively coupled to, the electronic device. Further, the subject technology initiates the recording of content within the field of view of the electronic device when the monitored sensor information indicates that at least one of the identified set of input modalities has been triggered.

Abstract: Systems and methods for gaze-driven recording of video are described. Some implementations may include accessing gaze data captured using one or more gaze-tracking sensors; applying a temporal filter to the gaze data to obtain a smoothed gaze estimate; determining a region of interest based on the smoothed gaze estimate, wherein the region of interest identifies a subset of a field of view; accessing a frame of video; recording a portion of the frame associated with the region of interest as an enhanced frame of video, wherein the portion of the frame corresponds to a smaller field of view than the frame; and storing, transmitting, or displaying the enhanced frame of video.

Abstract: A system comprises an encoder configured to compress and encode data for three-dimensional volumetric content. The encoder also is configured to segment the three-dimensional volumetric content based on viewing areas, wherein different ones of the viewing areas correspond to visible portions of the volumetric content. The system may provide metadata to a client device to support viewport adaptive rendering of the three-dimensional volumetric content or may adaptively stream portions of the three-dimensional volumetric content to a rending device based on viewing areas of the three-dimensional volumetric content that are to be rendered at the rendering device.

Abstract: Implementations of the subject technology provides analyzing a recording of content. The subject technology generates metadata information based at least in part on the analyzing. The subject technology identifies, based at least in part on at least one of a user preference or a detected event, a region of interest or an object of interest in the recording of content. Based at least in part on the identified region of interest or object of interest, the subject technology generates a modified version of the recording of content. Further, the subject technology stores the modified version of the recording of content for subsequent playback on an electronic device.

Abstract: Implementations of the subject technology provides analyzing a recording of content within a field of view of a device, the analyzing including recognition of a set of objects included in the content. The subject technology identifies a subset of the set of objects that are indicated as corresponding to protected content. The subject technology generates a modified version of the recording that obfuscates or filters the subset of the set of objects. Additionally, the subject technology provides the modified version of the recording to a host application for playback.

Abstract: A head-mounted device is provided that includes a variety of subsystems for generating extended reality content, displaying the extended reality content, and recording the extended reality content. The device may include a graphics rendering pipeline configured to render virtual content, tracking sensors configured to obtain user tracking information, a virtual content compositor configured to composite virtual frames based on the virtual content and the user tracking information, cameras configured to capture a video feed, a media merging compositor configured to overlay the composited virtual frames and the video feed, and a recording pipeline configured to record parameters, metadata, raw content, and/or adjusted content in an extended reality recording file. The extended reality recording file may have multiple discrete portions that may each be individually edited. The extended reality recording file may be used to present a replay on the head-mounted device and/or may be exported to an external device.

Abstract: An encoder encodes three-dimensional (3D) volumetric content, such as immersive media, using video encoded attribute patch images packed into a 2D atlas to communicate the attribute values for the 3D volumetric content. The encoder also uses mesh-encoded sub-meshes to communicate geometry information for portions of the 3D object or scene corresponding to the attribute patch images packed into the 2D atlas. The encoder applies decimation operations to the sub-meshes to simplify the sub-meshes before mesh encoding the sub-meshes. A distortion analysis is performed to bound the level to which the sub-meshes are simplified at the encoder. Mesh simplification at the encoder reduces the number of vertices and edges included in the sub-meshes which simplifies rendering at a decoder receiving the encoded 3D volumetric content.

Abstract: One or more computing devices implement a mesh analysis for evaluating meshes to be rendered when rendering immersive content. The mesh analysis identifies objects in a three-dimensional scene and determines geometrical complexity values for the objects. Objects with similar geometrical complexities are grouped into areas and a mesh vertices budget is determined for the respective areas. Metadata indicating the area definitions and corresponding mesh vertices budgets are generated. The metadata may be uploaded to a server to simplify meshes in the scene prior to streaming to a client, or the metadata may be provided to a client for use in simplifying the meshes as part of rendering the scene.
