    • Accurate Tangential Velocities For Solid Fluid Coupling 

      Robinson-Mosher, Avi; English, R. Elliot; Fedkiw, Ronald (ACM SIGGRAPH / Eurographics Association, 2009)
      We propose a novel method for obtaining more accurate tangential velocities for solid fluid coupling. Our method works for both rigid and deformable objects as well as both volumetric objects and thin shells. The fluid can ...

    • Anisotropic Friction for Deformable Surfaces and Solids 

      Pabst, Simon; Thomaszewski, Bernhard; Straßer, Wolfgang (ACM SIGGRAPH / Eurographics Association, 2009)
      This paper presents a method for simulating anisotropic friction for deforming surfaces and solids. Frictional contact is a complex phenomenon that fuels research in mechanical engineering, computational contact mechanics, ...

    • Automatic Construction of a Minimum Size Motion Graph 

      Zhao, Liming; Normoyle, Aline; Khanna, Sanjeev; Safonova, Alla (ACM SIGGRAPH / Eurographics Association, 2009)
      Motion capture data have been used effectively in many areas of human motion synthesis. Among those, motion graph-based approaches have shown great promise for novice users due to their ability to generate long motions and ...

    • Bounded Normal Trees for Reduced Deformations of Triangulated Surfaces 

      Schvartzman, Sara C.; Gascón, Jorge; Otaduy, Miguel A. (ACM SIGGRAPH / Eurographics Association, 2009)
      Several reduced deformation models in computer animation, such as linear blend skinning, point-based animation, embedding in finite element meshes, cage-based deformation, or subdivision surfaces, define surface vertex ...

    • 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 ...

    • Efficient and Robust Annotation of Motion Capture Data 

      Müller, Meinard; Baak, Andreas; Seidel, Hans-Peter (ACM SIGGRAPH / Eurographics Association, 2009)
      In view of increasing collections of available 3D motion capture (mocap) data, the task of automatically annotating large sets of unstructured motion data is gaining in importance. In this paper, we present an efficient ...

    • Energy Stability and Fracture for Frame Rate Rigid Body Simulations 

      Su, Jonathan; Schroeder, Craig; Fedkiw, Ronald (ACM SIGGRAPH / Eurographics Association, 2009)
      Our goal is to design robust algorithms that can be used for building real-time systems, but rather than starting with overly simplistic particle-based methods, we aim to modify higher-end visual effects algorithms. A major ...

    • 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 ...

    • 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 ...

    • Face/Off: Live Facial Puppetry 

      Weise, Thibaut; Li, Hao; Gool, Luc Van; Pauly, Mark (ACM SIGGRAPH / Eurographics Association, 2009)
      We present a complete integrated system for live facial puppetry that enables high-resolution real-time facial expression tracking with transfer to another person's face. The system utilizes a real-time structured light ...

    • 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 ...

    • 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 ...

    • 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 ...

    • Interactive Editing of Motion Style Using Drives and Correlations 

      Neff, Michael; Kim, Yejin (ACM SIGGRAPH / Eurographics Association, 2009)
      Animation data, from motion capture or other sources, is becoming increasingly available and provides high quality motion, but is difficult to customize for the needs of a particular application. This is especially true ...

    • Interactive Synthesis of Human-Object Interaction 

      Jain, Sumit; Liu, C. Karen (ACM SIGGRAPH / Eurographics Association, 2009)
      We present an interactive motion editing tool for creating dynamic scenes with human and object interaction. Our approach solves for an optimal control problem that leverages methods for physics-based rigid body control ...

    • Leveraging the Talent of Hand Animators to Create Three-Dimensional Animation 

      Jain, Eakta; Sheikh, Yaser; Hodgins, Jessica (ACM SIGGRAPH / Eurographics Association, 2009)
      The skills required to create compelling three-dimensional animation using computer software are quite different from those required to create compelling hand animation with pencil and paper. The three-dimensional medium ...

    • A Point-Based Method for Animating Elastoplastic Solids 

      Gerszewski, Dan; Bhattacharya, Haimasree; Bargteil, Adam W. (ACM SIGGRAPH / Eurographics Association, 2009)
      In this paper we describe a point-based approach for animating elastoplastic materials. Our primary contribution is a simple method for computing the deformation gradient for each particle in the simulation. The deformation ...

    • A Point-based Method for Animating Incompressible Flow 

      Sin, Funshing; Bargteil, Adam W.; Hodgins, Jessica K. (ACM SIGGRAPH / Eurographics Association, 2009)
      In this paper, we present a point-based method for animating incompressible flow. The advection term is handled by moving the sample points through the flow in a Lagrangian fashion. However, unlike most previous approaches, ...

      Mukai, Tomohiko; Kuriyama, Shigeru (ACM SIGGRAPH / Eurographics Association, 2009)
