Abstract: A system for modifying data representing a virtual environment includes: an environment navigation unit operable to control navigation within the virtual environment to generate one or more viewpoints within the virtual environment, an environment identification unit operable to identify one or more aspects of the geometry of the virtual environment visible in the one or more viewpoints, a geometry evaluation unit operable to evaluate the visibility of one or more aspects of the geometry based upon the identification for each of one or more viewpoints, and a data modification unit operable to modify one or more elements of data representing the virtual environment.

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: An apparatus includes a video display to display video images to a user; a gaze detector configured to detect a gaze direction for one or both eyes of the user while the user views the display; a head tracker configured to detect a head orientation of the user; an image processor configured to generate the video images for display by the video display; the image processor being responsive to one or more control functions dependent upon the gaze direction detected by the gaze detector; and a controller configured to detect a predetermined condition and, in response to detection of the predetermined condition, to control the image processor to be responsive to one or more control functions dependent upon the head orientation detected by the head tracker in place of the one or more control functions dependent upon the gaze direction detected by the gaze detector.

Abstract: A system for performing a raytracing process, the system comprising a bounding volume hierarchy, BVH, identification unit operable to identify a BVH structure for use in generating images of a virtual environment, the BVH structure comprising information about one or more surfaces within the virtual environment, a BVH selection unit operable to discard one or more elements of the BVH structure in dependence upon a direction of an incident ray, and a raytracing unit operable to perform a raytracing process using the remaining BVH elements.

Abstract: An image processing method includes generating an initial representation of a three-dimensional environment using a three-dimensional array of elements having a first spatial resolution with respect to the three-dimensional environment; generating a distance field, DF, representation from the initial representation, the DF representation including a three-dimensional array of distance values having a second spatial resolution with respect to the three-dimensional environment; and applying a data compression process to the DF representation to generate a data-compressed DF representation.
