Abstract:
Creating the digital effects for cooking in Ratatouille posed a number
of unique challanges. First we had to adopt efficient methods for
simulating a wide variety of material behaviours. Second we needed to
direct our simulations in order to match the expressiveness of the
character's animation, e.g. forming specific shapes while the
character pounds a dough. Finally we had to apply shading to our
simulated surfaces which underwent complex deformations and
topological changes. In this sketch we will focus on materials ranging
from elastoplastic solids to viscous liquids and illustrate with
several shot examples from the film.
