Deformable Objects Alive!

This paper presents a method for controlling the motions of deformable characters by dynamically adapting rest shapes in order to induce deformations that, together with environment interactions, result in purposeful and physically
plausible motions.

Interactive Editing of Deformable Simulations

An approach to editing complex deformable-object animations at interactive rates. Given an input 3D solid or cloth animation, optionally with contacts, the method enables artists to interactively perform quality large-deformation edits.

Interactive Spacetime Control of Deformable Objects

A technique that allows spacetime control over motions of deformable objects. It has interactive response times and produces explicit parametrizations of the motion. Ingredients are model reduction, modal coordinates, and a closed-form representation of the so-called wiggly splines.

Rig-Space Physics

A method that brings the benefits of physics-based simulations to traditional animation pipelines by formulating the equations of motions in the subspace of deformations defined by an animator's rig. The method outputs animation curves that are identical in nature to the result of manual keyframing.

Fast Simulation of Skeleton-Driven Deformable Body Characters

This method for fast, physically based simulation of skeleton-driven creatures with deformable bodies computes the passive jiggling behavior of a soft body driven by a skeleton. It was applied to a direct and interactive user-control system to create realistic self-propelled motions of soft-body characters.
