    • 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, ...
    • Pose-Timeline for Propagating Motion Edits 

      Mukai, Tomohiko; Kuriyama, Shigeru (ACM SIGGRAPH / Eurographics Association, 2009)
      Motion editing often requires repetitive operations for modifying similar action units to give a similar effect or impression. This paper proposes a system for efficiently and flexibly editing the sequence of iterative ...
    • Preface and Table of Contents 

      Eitan Grinspun and Jessica Hodgins (ACM SIGGRAPH / Eurographics Association, 2009)
    • Real-Time Deformation and Fracture in a Game Environment 

      Parker, Eric G.; O'Brien, James F. (ACM SIGGRAPH / Eurographics Association, 2009)
      This paper describes a simulation system that has been developed to model the deformation and fracture of solid objects in a real-time gaming context. Based around a corotational tetrahedral finite element method, this ...
    • Simulating Balance Recovery Responses to Trips Based on Biomechanical Principles 

      Shiratori, Takaaki; Coley, Brooke; Cham, Rakié; Hodgins, Jessica K. (ACM SIGGRAPH / Eurographics Association, 2009)
      To realize the full potential of human simulations in interactive environments, we need controllers that have the ability to respond appropriately to unexpected events. In this paper, we create controllers for the trip ...
    • Spatial Deformation Transfer 

      Ben-Chen, Mirela; Weber, Ofir; Gotsman, Craig (ACM SIGGRAPH / Eurographics Association, 2009)
      Much effort is invested in generating natural deformations of three-dimensional shapes. Deformation transfer simplifies this process by allowing to infer deformations of a new shape from existing deformations of a similar ...
    • Statistical Simulation of Rigid Bodies 

      Hsu, Shu-Wei; Keyser, John (ACM SIGGRAPH / Eurographics Association, 2009)
      We describe a method for replacing certain stages of rigid body simulation with a statistically-based approximation. We begin by collecting statistical data regarding changes in linear and angular momentum for collisions ...
    • 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 ...
    • Style Learning and Transferring for Facial Animation Editing 

      Ma, Xiaohan; Le, Binh Huy; Deng, Zhigang (ACM SIGGRAPH / Eurographics Association, 2009)
      Most of current facial animation editing techniques are frame-based approaches (i.e., manually edit one keyframe every several frames), which is ineffective, time-consuming, and prone to editing inconsistency. In this ...
