    • 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 ...

      Wang, Robert; Paris, Sylvain; Popovi, Jovan (The Eurographics Association, 2011)
      Motion capture systems have been widely used for high quality content creation and virtual reality but are rarely used in consumer applications due to their price and setup cost. In this paper, we propose a motion capture ...

      In this work, we describe an automated method for directing the control of a high resolution gaseous fluid simulation based on the results of a lower resolution preview simulation. Small variations in accuracy between low ...
    • Procedural Fluid Modeling of Explosion PhenomenaBased on Physical Properties 

      Kawada, Genichi; Kanai, Takashi (The Eurographics Association, 2011)
      We propose a method to procedurally model the fluid flows of explosion phenomena by taking physical properties into account. Explosion flows are always quite difficult to control, because they easily disturb each other and ...
    • Content Retargeting Using Parameter-Parallel Facial Layers 

      Kholgade, Natasha; Matthews, Iain; Sheikh, Yaser (The Eurographics Association, 2011)
      Facial motion retargeting approaches often transfer expressions by establishing correspondences between shared units of motion, such as action units, or spatial correspondences of landmarks between the source actor and ...
    • Perceptual evaluation of footskate cleanup 

      Pra ák, Martin; Hoyet, Ludovic; O'Sullivan, Carol (The Eurographics Association, 2011)
      When animating virtual humans for real-time applications such as games and virtual reality, animation systems often have to edit motions in order to be responsive. In many cases, contacts between the feet and the ground ...
    • Robust Real-Time Deformation of Incompressible Surface Meshes 

      Diziol, R.; Bender, J.; Bayer, D. (The Eurographics Association, 2011)
      We introduce an efficient technique for robustly simulating incompressible objects with thousands of elements in real-time. Instead of considering a tetrahedral model, commonly used to simulate volumetric bodies, we simply ...
    • 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 ...

      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 ...
    • 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 ...
    • Graph-based Fire Synthesis 

      Zhang, Yubo; Correa, Carlos D.; Ma, Kwan-Liu (The Eurographics Association, 2011)
      We present a novel graph-based data-driven technique for cost-effective fire modeling. This technique allows composing long animation sequences using a small number of short simulations. While traditional techniques such ...

      Twigg, Christopher D.; Kacic-Alesic, Zoran (The Eurographics Association, 2011)
      A common problem during the first few seconds of a cloth, hair, or flesh simulation is that the mesh sags under gravity, which can undo the work of hours of careful modeling. The typical response of increasing the stiffness ...
