vorticity confinement

Here’s the previous advection-reaction-diffusion simulation with additional vorticity confinement and buoyancy terms. This gives me more control over the vortices and overall flow of the field. In the video I alternate the strength and direction of the buoyancy with mouse input. Coupled with reaction-diffusion, the grid fills up quickly, so I’m already thinking of intuitive ways to manage this without resetting everything. The implementation described here was a big help.
