Vortex filaments provide an intuitive and compact tool for the simulation of smoke in the context of special effects. We present a model that includes moving obstacles with vortex shedding as well as variational filament reconnection. The method is able to simulate smoke in high detail at interactive rates, even over long simulation periods.

Furthermore, we will present a method to decompose an existing velocity field (on a grid) into a set of vortex filaments, approximating the given field. This approach is related to the stippling of gray-scale images, and to the placement of cone singularities on surfaces.
