A Material Point Method for Snow Simulation
Abstract
The paper presents a novel snow simulation
method utilizing a user-controllable
elasto-plastic constitutive model integrated
with a hybrid Eulerian/Lagrangian Material
Point Method (MPM). The method is continuum based
and its hybrid nature allows us to use a
regular Cartesian grid to automate treatment
of self-collision and fracture. It also
naturally allows us to derive a grid-based
semi-implicit integration scheme that has
conditioning independent of the number of
Lagrangian particles.

The method is the core of the production simulator Matterhorn at Walt Disney Animation Studios which was used extensively for deep snow effects in Frozen (2013).
