Simulating Wind Effects on Cloth and Hair in Disney's Frozen
The winter wonderland of Disney’s feature animation Frozen presented several unique technical and creative challenges for the Character Simulation team. One of the most prominent was cap- turing the interaction of wind with the cloth and hair simulations. The approach to meet this challenge involved low level changes to the simulation software, the creation of custom fields and visualizers, and the integration of "windicator" and wind gust rigs into the shot production pipeline. These three primary components gave the artists a tool set that allowed them to hit the desired art direction.
