The Stretch modifier simulates the traditional
animation effect of "squash-and-stretch." Stretch
applies a scale effect along a specified stretch axis
and an opposite scale along the two remaining
minor axes.
Theamountofoppositescalingontheminoraxes
varies, based on distance from the center of the
scale effect. The maximum amount of scaling
occurs at the center and falls off toward the ends.
Applying a Stretch modifier to the object on the left c rea tes
