Does the SDK provide a noise or turbulence function?

[Richard Rosenman]

As the title says, I am looking to implement 3D turbulence for one of my plugins. I doubt the SDK provides this as I haven't ever seen anything close. I suppose the wiggle expression in After Effects isn't far off as it provides 2D noise frequency and intensity, although I don't think this can be accessed within the SDK (unless as an expression). Plus, I'm not sure it's very close to turbulence.

The alternative of course is to find a library but they all seem overly complex like OpenFoam. I can't seem to find a simple, compact and light-weight library to work with.

Has anyone ever had to use 3D turbulence / noise in their plugins and if so, what tools did you end up using? 

Thanks,

-Richard

The SDK doesn't give any inbuilt noise functions. Is it specifically 3D turbulence? I'd recommend shadertoy for some simplex 2D noise, I haven't looked if they have 3D noise as well but I'd wager it's out there.
