    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
    • Preface and Table of Contents 

      Eitan Grinspun and Jessica Hodgins (ACM SIGGRAPH / Eurographics Association, 2009)
    • 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, ...
    • 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 ...
    • Visibility Transition Planning for Dynamic Camera Control 

      Oskam, Thomas; Sumner, Robert W.; Thuerey, Nils; Gross, Markus (ACM SIGGRAPH / Eurographics Association, 2009)
      We present a real-time camera control system that uses a global planning algorithm to compute large, occlusion free camera paths through complex environments. The algorithm incorporates the visibility of a focus point into ...
    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
    • 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, ...
    • 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 ...
    • 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 ...
    • 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 ...
