    • Exact volume preserving skinning with shape control 

      Rohmer, Damien; Hahmann, Stefanie; Cani, Marie-Paule (ACM SIGGRAPH / Eurographics Association, 2009)
      In the real world, most objects do not loose volume when they deform: they may for instance compensate a local compression by inflating in the orthogonal direction, or, in the case of a character, preserve volume through ...

    • ClearPath: Highly Parallel Collision Avoidance for Multi-Agent Simulation 

      Guyy, Stephen. J.; Chhugani, Jatin; Kim, Changkyu; Satish, Nadathur; Lin, Ming; Manocha, Dinesh; Dubey, Pradeep (ACM SIGGRAPH / Eurographics Association, 2009)
      We present a new local collision avoidance algorithm between multiple agents for real-time simulations. Our approach extends the notion of velocity obstacles from robotics and formulates the conditions for collision free ...

    • Experiment-based Modeling, Simulation and Validation of Interactions between VirtualWalkers 

      Pettré, Julien; Ondrej, Jan; Olivier, Anne-Hélène; Cretual, Armel; Donikian, Stéphane (ACM SIGGRAPH / Eurographics Association, 2009)
      An interaction occurs between two humans when they walk with converging trajectories. They need to adapt their motion in order to avoid and cross one another at respectful distance. This paper presents a model for solving ...

    • Guiding of Smoke Animations Through Variational Coupling of Simulations at Different Resolutions 

      Nielsen, Michael B.; Christensen, Brian B.; Zafar, Nafees Bin; Roble, Doug; Museth, Ken (ACM SIGGRAPH / Eurographics Association, 2009)
      We propose a novel approach to guiding of Eulerian-based smoke animations through coupling of simulations at different grid resolutions. Specifically we present a variational formulation that allows smoke animations to ...

    • Fitting Behaviors to Pedestrian Simulations 

      Lerner, Alon; Fitusi, Eitan; Chrysanthou, Yiorgos; Cohen-Or, Daniel (ACM SIGGRAPH / Eurographics Association, 2009)
      In this paper we present a data-driven approach for fitting behaviors to simulated pedestrian crowds. Our method annotates agent trajectories, generated by any crowd simulator, with action-tags. The aggregate effect of ...

    • SteerBug: An Interactive Framework for Specifying and Detecting Steering Behaviors 

      Kapadia, Mubbasir; Singh, Shawn; Allen, Brian; Reinman, Glenn; Faloutsos, Petros (ACM SIGGRAPH / Eurographics Association, 2009)
      The size of crowds that modern computer games and urban simulations are capable of handling has given rise to the challenging problem of debugging and testing massive simulations of autonomous agents. In this paper, we ...

    • Fast and Robust Tracking of Fluid Surfaces 

      Müller, Matthias (ACM SIGGRAPH / Eurographics Association, 2009)
      Surface tracking is an important problem with applications in many research fields. Among the most famous examples in computer graphics is the simulation and rendering of liquids with free surfaces. A surface that is ...
