摘要： Some embodiments of a method may include tracking a distance between a local VR device and a remote VR device; selecting an experience-sharing mode from a plurality of experience-sharing modes based on the tracked distance; and providing a different degree of immersive user experience to a user at the local VR device depending on the selected experience-sharing mode, wherein as the distance between the local VR device and the remote VR device decreases, the experience-sharing mode changes and the degree of immersive user experience increases. Some embodiments of another method may include detecting a gesture made by a user; selecting an immersiveness mode from a plurality of immersiveness modes based on the detected gesture; and providing a degree of immersive user experience to a local VR device user depending on the selected immersiveness mode.

摘要： Systems and methods are described for compressing color information in point cloud data. In some embodiments, point cloud data includes point position information and point color information for each of a plurality of points. The point position information is provided to a neural network, and the neural network generates predicted color information (e.g. predicted luma and chroma values) for respective points in the point cloud. A prediction residual is generated to represent the difference between the predicted color information and the input point color position. The point position information (which may be in compressed form) and the prediction residual are encoded in a bitstream. In some embodiments, color hint data is encoded to improve color prediction.

摘要： Systems and methods are described for providing spatial content using a hybrid format. In some embodiments, a client device receives, from a server, surface light field representations of a plurality of scene elements in a 3D scene, including a first scene element. The client device provides to the server an indication of a dynamic behavior of a second scene element different from the first scene element. Further, in response to the indication, the client device receives from the server information defining the first scene element in a 3D asset format. The client device then renders at least the first scene element in the 3D asset format.

摘要： Systems and methods are described for rendering a 3D synthetic scene. A display client receives point cloud samples of the scene, where the point cloud samples include a point location, one or more viewing directions, and color information for each of the viewing directions. The point cloud samples may be generated by a server using ray tracing. The display client combines information from the point cloud samples with a locally generated rendering of at least a portion of the scene to generate a combined rendering of the scene, and the client displays the combined rendering. The number of point cloud samples may be adjusted adaptively based on performance metrics at the client.
