Fast Proximity Computation Among Deformable Models Using Discrete Voronoi Diagrams
Novel algorithms to perform collision and distance queries among deformable models in complex environments. This paper demonstrates significant speedups over prior techniques on cloth simulation and breaking-object scenarios.

Resolving Surface Collisions Through Intersection Contour Minimization
A simple and easy-to-implement method for resolving intersections between colliding surfaces by inducing relative displacements that minimize the length of intersection contours.

Continuum Crowds
A crowd model based on continuum dynamics rather than agent rules. Our system runs at interactive rates, exhibits smooth flow, and produces emergent phenomena observed in real crowds.
