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!
