# BMS Friday: Decomposing Smoke into Smoke Rings

We present an algorithm to approximate the velocity field of an isolated vortex in an infinite ideal fluid (“smoke“) by the field generated by a finite number of closed vortex filaments (“smoke rings“). These vortex filaments in turn can be used to efficiently compute the time evolution of the flow. We indicate how the same ideas also can be applied in the context of approximating smooth surfaces by polyhedra.
