    Abstract: An image rendering method for rendering a pixel of a virtual scene at a viewpoint includes: downloading a machine learning system corresponding to a current or anticipated state an application determining the virtual scene to be rendered from among a plurality of machine learning systems corresponding to a plurality of states of the application; providing a position and a direction based on the viewpoint to the machine learning system previously trained to predict a factor; combining the predicted factor from the machine learning system with a distribution function that characterises an interaction of light with a predetermined surface to generate the pixel value corresponding to an illuminated first element of the virtual scene at the position; and incorporating the pixel value into a rendered image for display.

    Abstract: A lighting probe placement system for estimating lighting probe positions within a virtual environment includes a geometry input processor configured to receive geometry of at least part of the virtual environment and prepare it for input to a machine learning system; a processor configured to implement the machine learning system, which has been trained to output lighting probe positions upon receiving input geometry of the at least part of the virtual environment; and an association processor configured to associate the output lighting probe positions with the at least part of the virtual environment for subsequent rendering.

    Abstract: An image rendering method for an entertainment device for rendering a pixel at a viewpoint includes: for a first element of a virtual scene, having a predetermined surface at a position within that scene, obtaining a machine learning system previously trained to predict a factor that, when combined with a distribution function that characterises an interaction of light with the predetermined surface, generates a pixel value corresponding to the first element of the virtual scene as illuminated at the position; providing the position and a direction based on the viewpoint to the machine learning system; combining the predicted factor from the machine learning system with the distribution function to generate the pixel value corresponding to the illuminated first element of the virtual scene at the position; and incorporating the pixel value into a rendered image for display; where the obtaining step comprises: identifying a current or anticipated state of an application determining the virtual scene to be rendered; requesting a download of a machine learning system corresponding to the current or anticipated state, from among a plurality of machine learning systems corresponding to a plurality of states of the application, accessible via a remote server; and downloading the requested machine learning system.

    Abstract: A system for restricting user motion using a robot includes a robot comprising one or more barrier elements, a processing unit operable to identify one or more boundaries in a real environment and/or a virtual environment, the boundaries corresponding to a predetermined extent of allowed motion in that environment, and a control unit operable to control the robot such that at least one barrier element is arranged at a position corresponding to one of the identified boundaries.

    Abstract: Audio communication apparatus comprises a set of two or more audio communication nodes; each audio communication node comprising: an audio encoder controlled by encoding parameters to generate encoded audio data to represent a vocal input generated by a user of that audio communication node, the encoded data being agnostic to which user who generated the vocal input; and an audio decoder controlled by decoding parameters to generate a decoded audio signal as a reproduction of a vocal signal generated by a user of another of the audio communication nodes, the decoding parameters being specific to the user of that other of the audio communication nodes.
