Abstract
A system and method for applying motion blur to an application window. Motion blur may be applied to pixel in a window by calculating a velocity vector for each pixel in the window with reference to velocity vectors calculated for each corner of the window. Motion blur may be implemented by placing a number of blur samples in a frame along the pixel velocity vector according to the size of the pixel vector, or by directionally downsampling then re-upsampling the content of the window. For a frame having multiple windows, the motion blur for each window may be determined independent of the motion of other windows or as a composite for windows moving together. According to an embodiment, for each pixel in the frame, the associated application window may be identified and the pixel blurred with reference to the corner velocities of the associated application window.
