We have likely all seen what a wind tunnel or a wind tunnel simulations looks like. With 3D applications having dynamics, fluids, smoke and other effects available at your fingertips, what is really involved with recreating a wind tunnel effect? How hard could it be?

Well, if you are using Side FX Houdini, it turns out that creating a visual wind-effect might not be as intuitive as you think. Sure, Houdini has all the effects that you will need, along with its procedural workflow. But how is it all put together?

Here, Stefan Sietzen shows how he came up with recreating the wind-tunnel effect, after seeing it in several really cool animated commercials. Turn out, if you know the trick to it, it’s really simple to set up!
