Hierarchical motion blur rasterization

摘要

Motion blur rasterization may involve executing a first test for each plane of a tile frustum. The first test is a frustum plane versus moving bounding box overlap test where planes bounding a moving primitive are overlap tested against a screen tile frustum. According to a second test executed after the first test, for primitive edges against tile corners, the second test is a tile corner versus moving edge overlap test. The corners of the screen space tile are tested against a moving triangle edge in two-dimensional homogeneous space.

1. A method of motion blur rasterization comprising:
traversing, using a graphics processor, a screen space region covered by a moving triangle, tile by tile; testing samples within the tile against the moving triangle; and executing a second test for triangle edges against tile corners, the second test being a tile corner versus moving edge overlap test, where the corners of the screen space tile are tested against the moving triangle edge.
