We present a method for stable buildup of snow on surfaces of arbitrary topology and geometric complexity. This is achieved by tracing quantities of snow, so-called snow packages, through a dynamic wind field. Dual compact level sets are used to represent geometry as well as accumulated snow. The level sets have also proven to be well suited for the internal boundaries for our Navier-Stokes solver, which produces a wind field that changes according to snow buildup. Our method is different from previous work in that all the addition of snow is done by local operations, avoiding computationally expensive global refinement procedures. The main contribution of this work is a dual level set method for particle interaction with level sets.
