Abstract: A method of operating a graphics processing system that generates “spacewarped” frames for display is disclosed. Primitive motion vectors are used to determine the motion of objects appearing in rendered application frames. The so-determined motion is then used to generate “spacewarped” versions of the rendered application frames.

Abstract: A computing device 2, such as a general-purpose smartphone or general-purpose tablet computing device, comprises one or more inertial sensors and an image sensor. The device 2 produces stereoscopic images of a virtual environment on the display during a virtual reality (VR) session controlled by a user of the computing device. The device conducts visual odometry using at least image data received from the image sensor, and selectively activates and deactivates the visual odometry according to activity of the user during the virtual reality session. When the visual odometry is activated, the device controls the virtual reality session by at least position information from the visual odometry. When the visual odometry is deactivated, the device controls the virtual reality session by at least orientation information from the one or more inertial sensors.

Abstract: A method of data processing for an augmented reality system. The method comprises obtaining augmented reality data output by an augmented reality application operating at a second trust level. The augmented reality data is for modifying a representation of a real-world environment for a user of the augmented reality system. The method also comprises obtaining object recognition data determined by an object recognition system operating at a first trust level. The object recognition data comprises an indication of an object belonging to a predetermined class of objects being present in the real-world environment. The method also comprises triggering modification of the augmented reality data in response to the object recognition data, based on prioritization of the first trust level over the second trust level.

Abstract: In a graphics processing system, a bounding volume 20 representing the volume of a scene to be rendered and a cube texture 30 representing the transparency of the surface of the bounding volume are defined. Then, when the scene is to be rendered for output, a colour to be used to represent a first sampling point 25 as seen from a viewpoint position 24 for the scene is determined by determining, for each of plural second sampling points 27 along a vector 26 from the first sampling point 25 to the viewpoint position 24, a transparency parameter indicative of the amount of light that falls on the second sampling point 27, and then using the determined transparency parameter values for each of the plural second sampling points 27 to determine the colour. Each transparency parameter is determined by determining a vector 29 to be used to sample a graphics texture 30 that represents the transparency of the surface of the bounding volume 20 in the scene, and then using the determined vector 29 to sample the graphics texture 30 to determine the transparency parameter value for the light source 22 for the second sampling point 27.

Abstract: An image processing system for an extended reality, XR, device comprising an eye-tracking subsystem, for determining a focus region of the eye, and a processor. The processor is configured to process application data to render image content for an application for display on the XR device, and obtain metadata indicating that a virtual object is to be generated as a hologram as part of the image content for display. Based on a determination that the virtual object belongs to a predetermined class of objects and is to be displayed in the focus region, the processor performs, using a neural network corresponding to the predetermined class of objects, foveated processing of the image content, including at least part of the hologram, such that relatively high-quality image content is generated for display in the focus region and relatively low-quality image content is generated for display outside the focus region.

Abstract: When processing regions of interest in frames in a data processing system that can execute a plurality of neural networks that are each configured to more optimally process a region of interest of a respective size, a region of interest is first identified within a frame, the size of the region of interest is determined, and one of the plurality of available neural networks is selected to use to process the region of interest based on the determined size. The region of interest is scaled to produce a scaled version of the region of interest, where the scaling is determined based on the selected neural network. The scaled version of the region of interest is then processed using the selected neural network.

Abstract: An extended-reality system is described which determines extended-reality data to be obtained from the remote network-connected storage based on a location of the extended-reality system. The extended-reality system determines a communication method by which to obtain the extended-reality data, wherein the extended-reality data may be obtained by one or more requests to the remote network-connected storage or by one or more requests to a local device outside of the extended-reality system. A request is sent to at least one of the local device via a peer-to-peer network and the remote network-connected storage in dependence upon the determination by the extended-reality system.
