Animating Wind-Driven Snow Buildup Using an Implicit Approach
Independent thesis Advanced level (degree of Magister), 20 points / 30 hpStudent thesis
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.
