Interactive Hybrid Simulation of Large-Scale Traffic - Picture

Interactive Hybrid Simulation of Large-Scale Traffic


Hybrid traffic couples agent-based and continuum methods for traffic simulation to capture important features while maintaining interactive speeds on very large road networks.

Pattern-Guided Smoke Animation with Lagrangian Coherent Structure - Picture

Pattern-Guided Smoke Animation with Lagrangian Coherent Structure


Animators can design and experiment preferred fluid dynamics results with low-cost simulations. Our approach confines the final outcome to the original design with flow patterns extracted from such results.

Interference Aware Geometric Modeling


While often a requirement for geometric models, there has been little
research in resolving the interaction of deforming surfaces during real-time modeling sessions. To address this important topic, we introduce an interference algorithm specifically designed for the domain of geometric modeling.

Imperceptible Relaxation of Collision Avoidance Constraints in Virtual Crowds


We experimentally evaluate spectator ability to detect collisions in crowd simulations. Objective is to solve collision only where required using a level-of-details technique and to speed up performances.

A Hybrid Iterative Solver for Robustly Capturing Coulomb Friction in Hair Dynamics


The collective hair dynamic behavior is greatly influenced by dry friction between fibers. Our new and robust solver for capturing Coulomb friction greatly enhances the realism of standard hair simulators.
