摘要： A technology that streams graphical components and rendering instructions to a client device, for the client device to perform the final rendering and overlaying of that content onto the client's video stream based on the client's most recent tracking of the device's position and orientation. A client device sends a request for augmented reality drawing data to a network device. In response, the network device generates augmented reality drawing data, which can be augmented reality change data based on the augmented reality information and previous client render state information, and sends the augmented reality drawing data to the client device. The client device receives the augmented reality drawing data and renders a visible representation of an augmented reality scene comprising overlaying augmented reality graphics over a current video scene obtained from a camera of the client device.

摘要： When performing tile-based rendering a first, pre-pass operation in which primitives in a sequence of primitives for a tile are processed to determine visibility information for the sequence of primitives, the visibility information being usable to determine whether or not fragments for a primitive in the sequence of primitives should subsequently be processed further for the render output, is performed. Thereafter a second, main pass operation is performed in which the further processing of fragments for primitives that were processed during the first, pre-pass operation is controlled based on the determined visibility information for the sequence of primitives, such that for fragments for which the visibility information indicates that the fragments should not be processed further for the render output some or all of the processing during the second, main pass is omitted. The visibility information comprises the depth buffer.

摘要： When processing primitives in a tile-based graphics processing system in which a render output is sub-divided into a plurality of tiles for rendering, before a primitive is written to a primitive list corresponding to a region of the render output, it is first written to one or more primitive queues allocated to respective regions of the render output. To write the primitives to primitive lists, primitives are written together from a primitive queue allocated to a region of the render output to the primitive list for that region of the render output, in a single primitive list write cycle.

摘要： Described herein are techniques for learning neural reflectance shaders from images. A set of one or more machine learning models can be trained to optimize an illumination latent code and a set of reflectance latent codes for an object within a set of input images. A shader can then be generated based on a machine learning model of the one or more machine learning models. The shader is configured to sample the illumination latent code and the set of reflectance latent codes for the object. A 3D representation of the object can be rendered using the generated shader.
