Animating Wind-Driven Snow Buildup Using an Implicit Approach

Abstract [en]

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.
