Abstract:
1. A method of creating motion blur, comprising: determining if a first frame is a blur frame; determining the value of a blur parameter associated with at least a portion of an object for the first frame; setting an evaluation time based upon the first frame time and the value of the blur parameter if the first frame is a blur frame; setting the evaluation time based upon the first frame time if the first frame is not a blur frame; evaluating the portion of the object associated with the blur parameter at the evaluation time to determine a pose of the object; repeating the steps of determining if the frame is a blur frame, determining the value of the blur parameter, setting the evaluation time, and evaluating the portion of the object for a second frame occurring after the first frame in an animated sequence; combining the evaluations of the portion of the object from at least the first and second frames to create composite object data specifying the poses of the object at the first and second frame times; and rendering the composite object data to create at least a portion of an image; wherein determining the value of the blur parameter includes: evaluating a blur animation variable at the time of a primary frame if the first frame is a blur frame; and evaluating the blur animation variable at the first frame time if the first frame is not a blur frame, wherein the blur animation variable changes the value of the blur parameter as a function of time.
