    • Mass and Momentum Conservation for Fluid Simulation 

      Lentine, Michael; Aanjaneya, Mridul; Fedkiw, Ronald (The Eurographics Association, 2011)
      Momentum conservation has long been used as a design principle for solid simulation (e.g. collisions between rigid bodies, mass-spring elastic and damping forces, etc.), yet it has not been widely used for fluid simulation. ...

    • A Multigrid Fluid Pressure SolverHandling Separating Solid Boundary Conditions 

      Chentanez, Nuttapong; Müller, Matthias (The Eurographics Association, 2011)
      We present a multigrid method for solving the linear complementarity problem (LCP) resulting from discretizing the Poisson equation subject to separating solid boundary conditions in an Eulerian liquid simulation's pressure ...

    • Controllable Hand Deformation from Sparse Examples with Rich Details 

      Huang, Haoda; Zhao, Ling; Yin, KangKang; Qi, Yue; Yu, Yizhou; Tong, Xin (The Eurographics Association, 2011)
      Recent advances in laser scanning technology have made it possible to faithfully scan a real object with tiny geometric details, such as pores and wrinkles. However, a faithful digital model should not only capture static ...

    • Physics-based Character Skinningusing Multi-Domain Subspace Deformations 

      Kimy, Theodore; James, Doug L. (The Eurographics Association, 2011)
      We propose a domain-decomposition method to simulate articulated deformable characters entirely within a subspace framework. The method supports quasistatic and dynamic deformations, nonlinear kinematics and materials, and ...

    • Scenario Space:Characterizing Coverage, Quality, and Failure of SteeringAlgorithms 

      Kapadia, Mubbasir; Wang, Matt; Singh, Shawn; Reinman, Glenn; Faloutsos, Petros (The Eurographics Association, 2011)
      Navigation and steering in complex dynamically changing environments is a challenging research problem, and a fundamental aspect of immersive virtual worlds. While there exist a wide variety of approaches for navigation ...

    • Simulating Heterogeneous Crowd BehaviorsUsing Personality Trait Theory 

      Guy, Stephen J.; Kim, Sujeong; Lin, Ming C.; Manocha, Dinesh (The Eurographics Association, 2011)
      We present a new technique to generate heterogeneous crowd behaviors using personality trait theory. Our formulation is based on adopting results of a user study to derive a mapping from crowd simulation parameters to the ...

    • Hybrid Smoothed Particle Hydrodynamics 

      Raveendrany, Karthik; Wojtanz, Chris; Turk, Greg (The Eurographics Association, 2011)
      We present a new algorithm for enforcing incompressibility for Smoothed Particle Hydrodynamics (SPH) by preserving uniform density across the domain. We propose a hybrid method that uses a Poisson solve on a coarse grid ...

    • SPH Granular Flow with Friction and Cohesion 

      Alduán, Iván; Otaduy, Miguel A. (The Eurographics Association, 2011)
      Combining mechanical properties of solids and fluids, granular materials pose important challenges for the design of algorithms for realistic animation. In this paper, we present a simulation algorithm based on smoothed ...

    • A Level-set Method for Skinning Animated Particle Data 

      Bhatacharya, Haimasree; Gao, Yue; Bargteil, Adam (The Eurographics Association, 2011)
      In this paper, we present a straightforward, easy to implement method for particle skinning-generating surfaces from animated particle data. We cast the problem in terms of constrained optimization and solve the optimization ...

    • A Particle-based Method for Preserving Fluid Sheets 

      Ando, Ryoichi; Tsuruno, Reiji (The Eurographics Association, 2011)
      We present a new particle-based method that explicitly preserves thin fluid sheets for animating liquids. Our primary contribution is a meshless particle-based framework that splits at thin points and collapses at dense ...
