weight map (described at the beginning
of this section) is a graduated weight
map with 0% influence at the bottom
and 100% at the top. Leave EffectSize
at 100%, but change WaveCycle to

10. You can see that the object sways back
and forth as if made of rubber. But if
you look closely, the deformation is
completely linear and the object
appears to slant, giving it a slightly
unnatural quality. What if we want the
deformation to be a little more natural?
We can affect the application of the
deformation by applying a mode. From
the Mode pop-up menu, choose
Square
and recalculate.
Square does not refer to the shape of the
motion (as in square, rectangle, or triangle).
Rather, it describes the application of the
deformation. Square here is a mathematical
term, as in E=mc². It amplifies the defor-
mation of our object by multiplying the

its motion. However, by using an influence
map (such as a weight map, selection set, or
even a surface), we can alter our object's
shape as well.
