Abstract
We present a new method for efficiently simulating art-directable deformable materials. We use example poses to
define subspaces of desirable deformations via linear interpolation. As a central aspect of our approach, we use
an incompatible representation for input and interpolated poses that allows us to interpolate between elements
individually. This enables us to bypass costly reconstruction steps and we thus achieve significant performance
improvements compared to previous work. As a natural continuation, we furthermore present a formulation of
example-based plasticity. Finally, we extend the directability of example-based materials and explore a number
of powerful control mechanisms. We demonstrate these novel concepts on a number of solid and shell animations
including artistic deformation behaviors, cartoon physics, and example-based pose space dynamics.
