Another use of squash and stretch is to help relieve the disturbing effect of
strobing that happens with very fast motion because sequencial positions of
an object become spaced far apart. When the action is slow enough, the
object's positions overlap, and the eye smooths the motion out. (figure 4a)
However, as the speed of the action increases, so does the distance between
positions. When the distance becomes far enough that the object does not
overlap from frame to frame, the eye then begins to perceive separate
images. (figure 4b) Accurate motion blur is the most realistic solution to
this problem of strobing, [8,9] but when motion blur is not available,
squash and stretch is an alternative: the object should be stretched enough so
that its positions do overlap from frame to frame (or nearly s
