Abstract: Examples are disclosed that relate to image reprojection. One example provides a method, comprising receiving a first rendered image comprising content associated with a viewer reference frame, receiving a second rendered image comprising content associated with a manipulator reference frame, and reprojecting the first rendered image based on a head pose of a user to thereby produce a first reprojected image. The method further comprises reprojecting the second rendered image based on the head pose of the user and a pose of the manipulator to thereby produce a second reprojected image, and outputting the first reprojected image and the second reprojected image for display as a composited image.

Abstract: One disclosed example provides a computing device comprising a processing device and a storage device storing instructions executable by the processing device to execute in a first local process an application that outputs digital content for rendering and display. During execution of the application, the instructions are executable to provide, to a second local or remote process, object information regarding an object to be rendered by the second local or remote process, receive, from the second local or remote process, a rendering of the object, output the rendering of the object to display the object, receive a manipulation made to the object, provide, to the second local or remote process, updated object information based on the manipulation made to the object, receive, from the second local or remote process, an updated rendering of the object, and output the updated rendering of the object to display the object.

Abstract: A method for compressing a depth image including a matrix of pixels, each pixel including a pixel depth value, includes dividing the depth image into a plurality of non-overlapping tiles. Each of the plurality of non-overlapping tiles includes a contiguous subset of pixels. For each of the plurality of non-overlapping tiles, the pixel depth values are quantized into quantized pixel depth values. For each of the plurality of non-overlapping tiles, the quantized pixel depth values are encoded into a compressed depth image.

Abstract: A method for compressing depth information for a three-dimensional virtual scene includes, at a computing device, recognizing a three-dimensional virtual scene including one or more locally-maintained virtual objects. Positioning information for one or more remotely-maintained virtual objects to be included in the three-dimensional virtual scene are received from a remote device. For a virtual view of the three-dimensional virtual scene having a virtual perspective, different portions of the virtual view are classified as belonging to one of a plurality of different occlusion classes, each of the plurality of different occlusion classes specifying an occlusion relationship between locally-maintained virtual objects and remotely-maintained virtual objects in the virtual view. A depth-compressed representation indicating the occlusion class for each of the different portions of the virtual view is output to the remote device.
