    • Elevation Cable Modeling for Interactive Simulation of Cranes 

      García-Fernandez, Ignacio; Pla-Castells, Marta; Martinez-Dura, Rafael J. (The Eurographics Association, 2008)
      In this paper, the way to simulate hoisting cables in real time is addressed. We overcome instability in such simulation by considering a two-layered model: a model for the dynamics of a cable passing through a set of ...
    • Motion-Motif Graphs 

      Beaudoin, Philippe; Coros, Stelian; Panne, Michiel van de; Poulin, Pierre (The Eurographics Association, 2008)
      We present a technique to automatically distill a motion-motif graph from an arbitrary collection of motion capture data. Motion motifs represent clusters of similar motions and together with their encompassing motion graph ...
    • DrivenShape - a Data-driven Approach for Shape Deformation 

      Kim, Tae-Yong; Vendrovsky, Eugene (The Eurographics Association, 2008)
      DrivenShape is a data-driven technique that exploits known correspondence between two sets of shape deformations (e.g. a character's pose and her shirt). It allows users to drive deformation of secondary object simply by ...
    • Meshless Modeling of Deformable Shapes and their Motion 

      Adams, Bart; Ovsjanikov, Maks; Wand, Michael; Seidel, Hans-Peter; Guibas, Leonidas J. (The Eurographics Association, 2008)
      We present a new framework for interactive shape deformation modeling and key frame interpolation based on a meshless finite element formulation. Starting from a coarse nodal sampling of an object's volume, we formulate ...
    • Staggered Poses: A Character Motion Representation for Detail-Preserving Editing of Pose and Coordinated Timing 

      Coleman, Patrick; Bibliowicz, Jacobo; Singh, Karan; Gleicher, Michael (The Eurographics Association, 2008)
      We introduce staggered poses - a representation of character motion that explicitly encodes coordinated timing among movement features in different parts of a character's body. This representation allows us to provide ...
    • Perceptually Guided Expressive Facial Animation 

      Deng, Zhigang; Ma, Xiaohan (The Eurographics Association, 2008)
      Most of current facial animation approaches largely focus on the accuracy or efficiency of their algorithms, or how to optimally utilize pre-collected facial motion data. However, human perception, the ultimate measuring ...
    • Low Viscosity Flow Simulations for Animation 

      Molemaker, Jeroen; Cohen, Jonathan M.; Patel, Sanjit; Noh, Jonyong (The Eurographics Association, 2008)
      We present a combination of techniques to simulate turbulent fluid flows in 3D. Flow in a complex domain is modeled using a regular rectilinear grid with a finite-difference solution to the incompressible Navier-Stokes ...
    • Action Capture with Accelerometers 

      Slyper, Ronit; Hodgins, Jessica (The Eurographics Association, 2008)
      We create a performance animation system that leverages the power of low-cost accelerometers, readily available motion capture databases, and construction techniques from e-textiles. Our system, built with only off-theshelf ...
    • Evolving Sub-Grid Turbulence for Smoke Animation 

      Schechter, Hagit; Bridson, Robert (The Eurographics Association, 2008)
      We introduce a simple turbulence model for smoke animation, qualitatively capturing the transport, diffusion, and spectral cascade of turbulent energy unresolved on a typical simulation grid. We track the mean kinetic ...
    • Puppet Master: Designing Reactive Character Behavior by Demonstration 

      Young, James E.; Igarashi, Takeo; Sharlin, Ehud (The Eurographics Association, 2008)
      Puppet Master is a system that enables designers to rapidly create interactive and autonomous animated character behaviors that react to a main character controlled by an end-user. The behavior is designed by demonstration, ...
    • Pose-Space Animation and Transfer of Facial Details 

      Bickel, Bernd; Lang, Manuel; Botsch, Mario; Otaduy, Miguel A.; Gross, Markus (The Eurographics Association, 2008)
      This paper presents a novel method for real-time animation of highly-detailed facial expressions based on a multi-scale decomposition of facial geometry into large-scale motion and fine-scale details, such as expression ...
    • Achieving Good Connectivity in Motion Graphs 

      Zhao, Liming; Safonova, Alla (The Eurographics Association, 2008)
      Motion graphs provide users with a simple yet powerful way to synthesize human motions. While motion graphbased synthesis has been widely successful, the quality of the generatedmotion depends largely on the connectivity ...
    • Synthesis of Interactive Hand Manipulation 

      Liu, C. Karen (The Eurographics Association, 2008)
      We present an interactive physics-based motion synthesis technique for creating hand manipulation across a wide variety of tasks, objects, user interventions, and stylistic preferences. Given an object being manipulated, ...
    • Interactive Terrain Modeling Using Hydraulic Erosion 

      Stava, Ondrej; Benes, Bedrich; Brisbin, Matthew; Krivanek, Jaroslav (The Eurographics Association, 2008)
      We present a step toward interactive physics-based modeling of terrains. A terrain, composed of layers of materials, is edited with interactive modeling tools built upon different physics-based erosion and deposition ...

      Yeh, Hengchin; Curtis, Sean; Patil, Sachin; Berg, Jur van den; Manocha, Dinesh; Lin, Ming (The Eurographics Association, 2008)
      We introduce the concept of composite agents to effectively model complex agent interactions for agent-based crowd simulation. Each composite agent consists of a basic agent that is associated with one or more proxy agents. ...
    • Two-way Coupling of Rigid and Deformable Bodies 

      Shinar, Tamar; Schroeder, Craig; Fedkiw, Ronald (The Eurographics Association, 2008)
      We propose a framework for the full two-way coupling of rigid and deformable bodies, which is achieved with both a unified time integration scheme as well as individual two-way coupled algorithms at each point of that ...
