Abstract:
A particularly heavy effects sequence in the film Ratatouille depicts
a colony of rats fleeing their home and crossing a long narrow river
in several makeshift boats during a rainy afternoon. Nearly the entire
sequence was photographed inches above the ground from a s
perspective. Although this perspective provided a very interesting
point of view of the world, it also brought an extra level of
difficulty to an already challenging sequence. A raindrop creating a
seemingly insignificant two-inch splash in the river could easily span
one third the height of our final image. Described below is our
approach to achieving believable water related effects from the point
of view of a rat.
