Hi
Just try various values for the horizontal wave.
As an experiment use a centred line of alphabet size 18 abcdefghijklmnopqrstuvwxyzabcdefghijkl This shouls just span the screen
H Waves is the number of waves horizontally from 1-10
H Amplitude is obviously amplitude from 0 - 20.
First set the V sliders to the left.
If you try a setting of 10 waves at amplitude 10 and speed of 0 you will see that the line of text becomes a standing wave apparently not moving left or right.
The speed setting governs the apparent wave direction.
Negative values show a wave movement to the right
Value of 0 No wave movement...Standing wave related to the number and amplitude settings.
Positive values show a wave movement to the left.
The speed of the wave being related to the degree of negativity or positivity.
The same applies to the v values but a mixture can produce quite complicated movement effects.
