Abstract
One embodiment provides a method to display video such as computer-rendered animation or other video. The method includes assembling a sequence of video frames featuring a moving object, each video frame including a plurality of subframes sequenced for display according to a schedule. The method also includes determining a vector-valued differential velocity of the moving object relative to a head of an observer of the video. At a time scheduled for display of a first subframe of a given frame, first-subframe image content transformed by a first transform is displayed. At a time scheduled for display of the second subframe of the given frame, second-subframe image content transformed by a second transform is displayed. The first and second transforms are computed based on the vector-valued differential velocity to mitigate artifacts.
