### 6.11.9 Number_Of_Waves

The `waves` and `ripples` patterns are generated by summing a series of waves, each with a slightly different center and size. By default, ten waves are summed but this amount can be globally controlled by changing the `number_of_waves` setting.

     global_settings { number_of_waves Integer }

Changing this value affects both waves and ripples alike on all patterns in the scene.
