Simulating Articulated Subspace Self-Contact

An efficient simulation method for articulated deformable bodies in self-contact. The method leverages subspace methods to devise an algorithm that does not need to detect and resolve all collisions in order to capture self-contact. It simulates colliding, high-resolution (400K) meshes at interactive rates.

Sensitivity-Optimized Rigging for Example-Based Real-Time Clothing Synthesis

A novel predict-then-blend scheme for data-driven real-time clothing animation that can produce realistic wrinkles. The prediction model is developed based on sensitivity analysis, and its implementation is as simple as rigging technique.

Space-Time Editing of Elastic Motion Through Material Optimization and Reduction

This novel method for elastic animation editing departs from previous approaches by proposing material optimization to better match user constraints. It also introduces a reduced rotation-strain space that accelerates motion optimization by several orders of magnitude.

Animating Deformable Objects using Sparse Spacetime Constraints

A scheme for animating soft-body characters and deformable objects from sparse input. Interesting motion with rich secondary motion can be created from partial keyframes for positions and velocities. The scheme is based on a framework for trajectory optimization with sparse spacetime constraints.
