APPARATUS AND METHOD FOR OPTIMIZING TIME/SPACE WARP FOR VIRTUAL REALITY USING DYNAMIC TILING AND DIRTY TILE MARKING

摘要

An apparatus and method for efficient rendering and transmission of video content in a virtual reality system. For example, one embodiment of an apparatus comprises: a first frame buffer to store image frames to be transmitted to a virtual reality apparatus; tile-based image rendering circuitry and/or logic to concurrently render multiple tiles of a first image frame, wherein tiles are categorized core tiles or a peripheral tiles; tile-based transmission circuitry and/or logic to transmit a first core tile rendered to the virtual reality apparatus before one or more remaining tiles have been rendered, the tile-based transmission circuitry and/or logic to continue to transmit one or more subsequently rendered core tiles following the first tile until all core tiles have been transmitted; and the tile-based transmission circuitry and/or logic to identify a subset of peripheral tiles to be transmitted based on first coordinate/offset data and to responsively transmit the subset of peripheral tiles.
