Horizontal modulation
This modulates the pattern, applying waviness in the horizontal direction to
edges.
The parameter Speed determines the speed of waves.
A value of –100.00 generates the maximum downward speed of waves, and a
value of +100.00 the maximum upward speed.
Vertical modulation
This modulates the pattern, applying waviness in the vertical direction to
edges.
The parameter Speed determines the speed of waves.
A value of –100.00 generates the maximum leftward speed of waves, and a
value of +100.00 the maximum rightward speed.
Fringe
This modulates the pattern, applying waviness in the radial direction to edges.
The parameter Speed determines the speed of waves.
A value of –100.00 generates the maximum counterclockwise speed of waves,
and a value of +100.00 the maximum clockwise speed.
You can apply modulation independently to the main pattern and sub pattern.
