Abstract
A system and method for adaptive hierarchical tessellation. For example, one embodiment of a method comprises: a tessellation queue to store portions of a first image frame to be tessellated; motion vector analysis circuitry to group a plurality of sub-tiles within each of a plurality of tiles at multiple levels of granularity, wherein the sub-tiles of a first level comprise pixels and the sub-tiles of each successive level comprise tiles from a previous level, the motion vector analysis circuitry to iteratively analyze motion vectors of each group of sub-tiles at each level of granularity to determine whether the motion vectors are similar in accordance with a defined threshold, the motion vector analysis circuitry to queue tiles having sub-tiles which are determined to be dissimilar to the tessellation queue.
