Phase effect 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 the
Decay value increases, the wave is concentrated
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 a n e qual distance.
Rotat ing and scaling the gizmo takes place with
respect to its center.
Center—At this sub-object level, you can translate
and animate the center, altering the Wa v e gizmo’s
shape, and thus the shape of the wavy object.

positive to negative reverses the positions of peaks

Wave L e ngth —Specifies the distance in current
units between the crests of both waves.
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 generated
from its origin . A decay value decreases the
amplitude at increasing distance from t he center.
As this value increases, the wave is concentrated
at the center and flattened until it disappears
(completely decays).
