    • Detail-Preserving Fluid Control 

      Thürey, Nils; Keiser, Richard; Pauly, Mark; Rüde, Ulrich (The Eurographics Association, 2006)
      We propose a new fluid control technique that uses scale-dependent force control to preserve small-scale fluid detail. Control particles define local force fields and can be generated automatically from either a physical ...

      Liu, C. Karen; Hertzmann, Aaron; Popovic, Zoran (The Eurographics Association, 2006)
      This paper presents a physics-based method for creating complex multi-character motions from short singlecharacter sequences. We represent multi-character motion synthesis as a spacetime optimization problem where constraints ...

      Galoppo, Nico; Otaduy, Miguel A.; Mecklenburg, Paul; Gross, Markus; Lin, Ming C. (The Eurographics Association, 2006)
      We present an efficient algorithm for simulating contacts between deformable bodies with high-resolution surface geometry using dynamic deformation textures, which reformulate the 3D elastoplastic deformation and collision ...
    • Fast Arbitrary Splitting of Deforming Objects 

      Steinemann, Denis; Otaduy, Miguel A.; Gross, Markus (The Eurographics Association, 2006)
      We present a novel algorithm for efficiently splitting deformable solids along arbitrary piecewise linear crack surfaces in cutting and fracture simulations. We propose the use of a meshless discretization of the deformation ...
    • Keyframe Control of Complex Particle Systems Using the Adjoint Method 

      Wojtan, Chris; Mucha, Peter J.; Turk, Greg (The Eurographics Association, 2006)
      Control of physical simulation has become a popular topic in the field of computer graphics. Keyframe control has been applied to simulations of rigid bodies, smoke, liquid, flocks, and finite element-based elastic bodies. ...
    • Physics-Based Motion Retiming 

      McCann, Jim; Pollard, Nancy S.; Srinivasa, Siddhartha (The Eurographics Association, 2006)
      By changing only the playback timing of a motion sequence, an animator can achieve a variety of effects that alter our perception of an event. In some scenarios, it may be important to consider physical properties of the ...
    • Robust Kinematic Constraint Detection for Motion Data 

      Callennec, Benoît Le; Boulic, Ronan (The Eurographics Association, 2006)
      Motion capture data is now widely available to create realistic character animation. However, it is di?cult to reuse without any additional information. For this reason, annotating motion data with kinematic constraints ...
    • Fat Graphs: Constructing an Interactive Character with Continuous Controls 

      Shin, Hyun Joon; Oh, Hyun Seok (The Eurographics Association, 2006)
      This paper proposes a methodology that allows users to control character s motion interactively but continuously. Inspired by the work of Gleicher et al. [GSKJ03], we propose a semi-automatic method to build fat graphs ...
    • A Consistent Bending Model for Cloth Simulation with Corotational Subdivision Finite Elements 

      Thomaszewski, Bernhard; Wacker, Markus; Straßer, Wolfgang (The Eurographics Association, 2006)
      Wrinkles and folds play an important role in the appearance of real textiles. The way in which they form depends mainly on the bending properties of the specific material type. Existing approaches fail to reliably reproduce ...
    • Perceptual Evaluation of LOD Clothing for Virtual Humans 

      McDonnell, Rachel; Dobbyn, Simon; Collins, Steven; O'Sullivan, Carol (The Eurographics Association, 2006)
      Recent developments in crowd simulation have allowed thousands of characters to be rendered in real-time. Usually this is achieved through the use of Level of Detail (LOD) models for the individuals in the crowd. Perceptual ...
    • Segment-Based Human Motion Compression 

      Liu, Guodong; McMillan, Leonard (The Eurographics Association, 2006)
      As more and more human motion data are becoming widely used to animate computer graphics figures in many applications, the growing need for compact storage and fast transmission makes it imperative to compress motion data. ...
