them in the other. This effect is especially clear
when animated.
Phase effec t on a wave
To add a decay effect:
Set a decay va lue to increase or decrease the
amplitude.
A decay value decreases the amplitude as the
distance from the center increases. As t he
Decay value increases, the wave is concent rated
at the center and flattens until it disappears
(completely decays).

Gizmo—At this sub-object level, you can transform
and animate the gizmo like any other object,
altering the effect of the Wave modifier. Translating
the gizmo translates its center an equal distance.
Rotating and scaling the gizmo takes place with
respect to its center.
CenterAt this sub-object level, you can translate
and animate the center, altering the Wave gizmo’s
shape, and thus the shape of the wavy object.
For more information on the stack display, see
Modifier Stack (page 3–760).

direction w ith both). Switching a value from
positive to negative reverses the positions of peaks
and troughs.
Wave Le ngt hSpecifies the distance in current

Phase—Shiftsthewavepatternovertheobject.
Positive numbers move the pattern in one
direction, while negative numbers move it in the
other. This effect is especially clear when animated.
Decay—Limits the effect of t he wave generate d
from its origin. A decay value decreases the
amplitude at increasing distance from the center.
As this value incr eases, the wave is concentrated
at the center and flattened until it disappears
(completely decays).
