Amplitude
This value scales the wave function in the Z direction, and the turbulence function in the Y direction.
To change the value interactively, drag the orange handle on the Z-axis.
Size
This value scales the deformer in the X-axis and Y-axis. Increasing this value will have the effect of
increasing the frequency of the waves. If the Flag option is checked, Size will also cause a more abrupt
change in the size of the X-axis envelope.
Frequency
The frequency determines the speed of the waves.
Turbulence
This setting adds secondary waves in the X direction, with amplitude in the +Z direction. In addition,
Turbulence adds a wave in the Y direction, with amplitude in the +Z direction. The percentage denes
the size of these secondary waves relative to the main waves.
fx, fy
These values determine the frequency of the waves in the X and Y directions.
Flag
If you enable this option, all points along the deformer’s Y-axis remain still (xed). For example, you
can use this to simulate a ag on a pole — one end of the ag aps freely in the wind, while the other
end is xed to the pole and does not move (place the deformer’s Y-axis along this end of the ag).
Flag activated — the wind
deformer’s Y-axis is located
at the left end of the ag. The
left end of the ag is xed.
Flag deactivated — the entire ag
aps freely in the wind. The left
end is no longer xed.
