Prediction based primitive sorting for tile based rendering

摘要

Techniques related to graphics rendering are discussed. Such techniques may include predicting primitive intersection information for tiles of a frame, rendering the frame on a tile-by-tile basis based on the predicted primitive intersection information, and re-rendering any tiles with predicted primitive errors.

1. An apparatus comprising:
a memory to receive prediction primitive intersection information associated with at least a first tile of a first frame; and logic coupled to the memory, the logic at least partially comprising hardware logic, the logic to access the predicted primitive intersection information, wherein the predicted primitive intersection information indicates one or more primitives predicted to overlap the first tile, to render the first tile based at least in part on the predicted primitive intersection information, to determine an unpredicted primitive overlaps the first tile, and to re-render the first tile based at least in part on the unpredicted primitive.
