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