I’m working on a simulation toy, and I want to model wind on my world/levels.

I’m currently using playrho (a box2d fork) with gravity set to 0 to model a top down view.

I assume the wind will be represented as a vector field. But I’m unsure what method to use to get this field.

Could someone point me in the right direction? Should I be looking at the navier-stokes equation? Does anybody know of any relevant tutorials?

Thanks in advance!
