Abstract: A mixed reality system that includes a device and a base station that communicate via a wireless connection The device may include sensors that collect information about the user's environment and about the user. The information collected by the sensors may be transmitted to the base station via the wireless connection. The base station renders frames or slices based at least in part on the sensor information received from the device, encodes the frames or slices, and transmits the compressed frames or slices to the device for decoding and display. The base station may provide more computing power than conventional stand-alone systems, and the wireless connection does not tether the device to the base station as in conventional tethered systems. The system may implement methods and apparatus to maintain a target frame rate through the wireless link and to minimize latency in frame rendering, transmittal, and display.

Abstract: Techniques are disclosed relating to rendering graphics objects. In some embodiments, a graphics unit is configured to transform graphics objects from a virtual space into a second space according to different transformation parameters for different portions of the second space. This may result in sampling different portions of the virtual space at different sample rates, which may reduce the number of samples required in various stages of the rendering process. In the disclosed techniques, transformation may occur prior to rasterization and shading, which may further reduce computation and power consumption in a graphics unit, improve image quality as displayed to a user, and/or reduce bandwidth usage or latency of video content on a network. In some embodiments, a transformed image may be viewed through a distortion-compensating lens or resampled prior to display.

Abstract: Techniques are disclosed relating to texture sampling operations. In some embodiments, multi-fetch sampling instructions specify a region of a texture in which multiple samples are to be performed and texture processing circuitry is configured to sample the texture multiple times within the region. In some embodiments, the locations of the samples are determined according to a formula, which may be pseudo-random. In some embodiments, the locations of the samples are jittered to produce stochastic results. In some embodiments, the locations of the samples are determined based on one or more stored sets of samples that have particular properties (e.g., blue noise, in some embodiments). In various embodiments, disclosed techniques may facilitate Monte Carlo sampling.
