@Deathrey Thanks for this amazing walkthrough.
A mechanics to seamlessly change wind speed and direction can be added. Logic to implement it is quite simple. To transition from initial state to target state, you would slowly fade a small group of wave signals in the spectrum, once they are faded out completely, prepare new initial amplitudes for them, and start fading them back in, while also fading out next set of amplitudes. Selecting wave signals to fade out and in can be done using Bayer matrix, blue noise or any other pattern. Worth experimenting.
Does anyone have an example implementation for this type of control?
