Abstract:
Contact is natural in the real world but often avoided in
3D animated features. Animators tend to make acting decisions that minimise
or avoid contact within and between their characters and the
world, and when apparent contact does occur, it can tend to feel
both "floaty" and unrealistic. "Ratatouille" called for dynamic,
tactile characters that would feel very much a part of their animated
environment, squashing into and against each other, props and the
world itself. The contact needed to be compelling and believable
within that cartoon world, and with that in mind we aimed to develop
and deploy technology that would allow animators to easily
setup collision relationships, make acting decisions with contact
response interactively, and alter the resultant shapes.
