Abstract: A method of rendering an image includes generating a virtual scene comprising a set of virtual resources, the virtual resources being virtual objects and/or virtual light sources; pre-processing the virtual scene by ray-tracing with respect to a virtual camera position to detect one or more virtual resources not required for ray-tracing rendering of at least an aspect of rendering the image; and rendering the image by a ray-tracing process from the virtual camera position, the ray-tracing process being configured to omit ray-tracing for at least a given aspect of the image, with respect to the one or more virtual resources not required for ray-tracing rendering of at least the given aspect of the image.

Abstract: An image generation system comprising an image rendering unit operable to render a first image for display to a first one of a user's eyes, an image obtaining unit operable to obtain a second image for a second one of the user's eyes, the obtained image having been rendered for display at an earlier time, an image reprojection unit operable to reproject the first image from a viewpoint associated with the first one of the user's eyes to a viewpoint associated with the second one of the user's eyes, and an image generation unit operable to generate an output image for the second one of the user's eyes in dependence upon the reprojected first image and the obtained second image.

Abstract: A method for texture encoding, the method comprising the steps of: compressing a first colour channel of a given texture to obtain a plurality of fixed-sized data chunks representative of the first colour channel of a corresponding plurality of fixed-sized blocks of pixels of the given texture; for the given texture, training, using the plurality of fixed-sized data chunks, a neural network to output an inferred pixel colour block representative of at least a second colour channel of a respective fixed-sized block of pixels of the given texture based on an input representative of a respective fixed-sized data chunk representative of the first colour channel of the respective fixed-sized block of pixels of the given texture; and outputting at least one of the fixed-sized data chunks and the weights of the trained neural network as an encoded representation of at least a portion of the given texture.

Abstract: A system includes a head-mountable display (HMD) configured to receive one or more signals via a wired connection with an external device, processing circuitry to generate an output indicative of at least one of a predicted disconnect event and a detected disconnect event for the wired connection, and control circuitry to instruct one or more operations to be performed by the HMD in response to the generated output.

Abstract: There is provided a method of generating a light probe in a virtual environment. The method includes determining a first region of the light probe based on one or more predetermined conditions, collecting light information from the virtual environment, where the light information relates to light passing through a location of the light probe in the virtual environment, and storing the light information in the light probe, where the light information is stored at a higher resolution in the first region of the light probe than in a, different, second region of the light probe.
