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.
