This is a general tool to generate turbulence on a grid. The data is periodic and can be used to tile alll of space and time. I wrote the first version in the dark winter of 1996-97 in Finland. It is based on my SIGGRAPH 1993 paper nd my PhD thesis and resulted in the publication "A General Animation Framework for Gaseous Phenomena". These papers available on my publications page.

​

The turbulence has seven dimensions. The turbulence is a function that maps space-time (t,x,y,z) to a vector field (u,v,w) and the grid is defined by its sizes, restricted to powers of two.

​

If Nt > 1, then this is turbulence is animated and periodic in time. Else when Nt = 1, the program generates a turbulence frozen in time. Nf =1 models a scalar (density field). While, Nf=2, 3 creates a two or three-dimensional vector field. The field can also be constrained to be a divergence free (incompressible) field or be a gradient field.
