Billowing smoke patterns created in Ready. This is a variation on the previously-posted Flux-Curl Fluid Simulation (http://youtu.be/1SoKtKfYkF4) using a different visualization method.

is this a simulation?

+Ivan DeWolf It's not a physics simulation. It's not even 3D, it just looks it from the pattern of light and dark. You can find the formula in the .vti file in the youtube description. Maybe +Cornus Ammonis can explain more.

+Tim Hutton +Ivan DeWolf It actually is a physics simulation of sorts. In Ready terms, this is a 2-reagent system, each reagent corresponding to one component of a 2D vector. At each point/pixel I compute local curl, flux, and divergence of the vector field. These values are used to update the reagent values. It's not a physically-accurate fluid simulation, but the resemblance is deliberate. In the end I also apply an anisotropic filter to give the visual appearance of an oblique lighting source.
