Abstract: A method is described for presenting graphics to a user, said method comprising (1) providing a 3D graphics system comprising a 3D graphics environment and at least one virtual object positioned in the 3D graphics environment, wherein the 3D graphics system is configured to use 3D mathematics, (2) providing a 2D graphics rendering engine configured to use 2D mathematics, and providing a library of sprites for use by the 2D graphics rendering engine, wherein for each sprite in the library, there is provided an array of rendered views for that sprite, based on horizontal and vertical angles, with the rendered views being expressed in 2D mathematics, (3) selecting a camera perspective within the 3D graphics environment, (4) based on selected camera perspective, generating an appropriate 2D view of the 3D graphics environment, (5) based on the generated 2D view, selecting an appropriate sprite and, for that sprite, the appropriate rendered view for that sprite, (6) determining the appropriate screen location and scale for the selected rendered view for the sprite and (7) instructing the 2D graphics rendering engine to paint the selected rendered view for the sprite to the determined screen location and with the determined scale.
