> Recently an Intel developer has written a series of articles about
> realtime vortex simulation for games. The demo

> )
> is spectacular and best of all runs in realtime. Sadly the algorithm is
> not open source and I wanted something similar in Blender… so you know the
> end, don’t you ;) ?
>
> I end up taking a different approach with similar results and I’m very
> pleased! my approach require more complex set up but more advanced user
> control and best of all is completely Lagrangian, I mean completely
> boundless , whether the Intel approach is a hybrid algorithm
> lagrangian/eulerian (lattice-particle method).

> I took advantage of the fact that the current Blender particle system is a
> second order simulation system , where particles act as  source of force
> field, and the current vortex particle field has the rotational vector
> very limited and locked to the particle velocity direction …. well, I have
> made a simple patch (http://www.pasteall.org/18508/diff) to allow more
> user control and watch yourself!
