Abstract
A method of mapping a virtual environment includes: obtaining a first sequence of video images output by a videogame title; obtaining a corresponding sequence of in-game virtual camera positions at which the video images were created; obtaining a corresponding sequence of depth buffer values for a depth buffer used by the videogame whilst creating the video images; and, for each of a plurality of video images and corresponding depth buffer values of the obtained sequences, obtain mapping points corresponding to a selected predetermined set of depth values corresponding to a predetermined set of positions within a respective video image; where for each pair of depth values and video image positions, a mapping point has a distance from the virtual camera position based upon the depth value, and a position based upon the relative positions of the virtual camera and the respective video image position, thereby obtaining a map dataset of mapping points corresponding to the first sequence of video images.
