Is wind force for particle system linear or exponential?

60 Views Asked by At

Hi gang!

I am developing a simple particle system mainly for learning purposes and I was wondering if a wind force is considered linear or exponential.

For example, would you implement it as linear:

Posx = posx + windx * time;

Or exponential:

Posx = posx + windx * time * time;

Let me add that I know a correct wind force takes other items into account such as mass, and more. But right now I am looking at it as a simple equation.

The reason I’m asking is because I’ve seen many particle systems implement it as a linear force but when I think of an aerosol can spraying in the wind, the particles seem to first shoot out in a particular direction before slowly being exponentially impacted by the wind force. It also doesn’t look very natural as a constant linear force.

Finally, I guess if it is exponential, it should have a maximum speed limit so that it doesn’t accelerate indefinitely, correct?

Thanks in advance for your suggestions!
