Applying modulation to the wipe pattern (Modulation)
The pattern signal can be modulated, giving waves on the horizontal or vertical
edges, or radially.
The parameter Shape determines the form of the modulation.
1: sine wave, 2: triangular wave, 3: rectangular wave
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.
