RENDERING VIEWS OF A SCENE IN A GRAPHICS PROCESSING UNIT

摘要

Graphics processing systems may render multiple views of a scene (e.g. a sequence of frames) in a tile-based manner. Groups of views may be rendered together such that tiles from a group of views are rendered in an interspersed order such that at least one tile from each of the views in the group is rendered before any of the views of the scene in the group are fully rendered. In this way similar tiles from different views within a group may be rendered sequentially. If a particular rendered tile is similar to the next tile to be rendered then data stored in a cache for rendering the particular tile is likely to be useful for rendering the next tile. Therefore, when rendering the next tile less data needs to be fetched from the system memory which can significantly improve the efficiency of the graphics processing system.

1. A method of rendering views of a scene in a graphics processing unit which is configured to use a rendering space which is subdivided into a plurality of tiles, the method comprising:
rendering tiles of the views of the scene in an interspersed order such that, for each group of a plurality of groups of views of the scene, at least one tile from each of the views of the scene in the group is rendered before any of the views of the scene in the group are fully rendered.
