    • Chimera Grids for Water Simulation 

      English, R. Elliot; Qiu, Linhai; Yu, Yue; Fedkiw, Ronald (ACM SIGGRAPH / Eurographics Association, 2013)
      We introduce a new method for large scale water simulation using Chimera grid embedding, which discretizes space with overlapping Cartesian grids that translate and rotate in order to decompose the domain into different ...
    • Rod Constraints for Simplified Ragdolls 

      Lewin, Chris; Thorman, Matt; Waterson, Tom; Williams, Chris; Willis, Phil (ACM SIGGRAPH / Eurographics Association, 2013)
      Physics-based animation has become a standard feature in modern games. Typically, the bones in a character's animation rig are each associated with a simulated rigid body, leading to a jointed assembly commonly called a ...
    • Consistent Surface Model for SPH-based Fluid Transport 

      Orthmann, Jens; Hochstetter, Hendrik; Bader, Julian; Bayraktar, Serkan; Kolb, Andreas (ACM SIGGRAPH / Eurographics Association, 2013)
      Surface effects play an essential role in fluid simulations. A vast number of dynamics including wetting of surfaces, cleansing, and foam dynamics are based on surface-surface and surface-bulk interactions, which in turn ...
    • A Hybrid Lagrangian-Eulerian Formulation for Bubble Generation and Dynamics 

      Patkar, Saket; Aanjaneya, Mridul; Karpman, Dmitriy; Fedkiw, Ronald (ACM SIGGRAPH / Eurographics Association, 2013)
      We present a hybrid Lagrangian-Eulerian framework for simulating both small and large scale bubble dynamics, where the bubbles can grow or shrink in volume as dictated by pressure forces in the surrounding fluid. Small ...
    • A Level Set Method for Ductile Fracture 

      Hegemann, Jan; Jiang, Chenfanfu; Schroeder, Craig; Teran, Joseph M. (ACM SIGGRAPH / Eurographics Association, 2013)
      We utilize the shape derivative of the classical Griffith's energy in a level set method for the simulation of dynamic ductile fracture. The level set is defined in the undeformed configuration of the object, and its ...
    • Modeling and Animating Myriapoda: A Real-Time Kinematic/Dynamic Approach 

      Fang, Jingyi; Jiang, Chenfanfu; Terzopoulos, Demetri (ACM SIGGRAPH / Eurographics Association, 2013)
      Unlike two, four, six, and eight legged animals, Myriapoda-i.e., centipedes, millipedes, etc.-have been largely overlooked in the computer graphics literature. We present an artificial life framework for modeling these ...
    • Accurate Surface Embedding for Higher Order Finite Elements 

      Suwelack, Stefan; Lukarski, Dimitar; Heuveline, Vincent; Dillmann, Rüdiger; Speidel, Stefanie (ACM SIGGRAPH / Eurographics Association, 2013)
      In this paper we present a novel approach to efficiently simulate the deformation of highly detailed meshes using higher order finite elements (FE). An efficient algorithm based on non-linear optimization is proposed in ...
    • Efficient Simulation of Secondary Motion in Rig-Space 

      Hahn, Fabian; Thomaszewski, Bernhard; Coros, Stelian; Sumner, Robert W.; Gross, Markus (ACM SIGGRAPH / Eurographics Association, 2013)
      We present an efficient method for augmenting keyframed character animations with physically-simulated secondary motion. Our method achieves a performance improvement of one to two orders of magnitude over previous work ...
    • Fast Deformation of Volume Data Using Tetrahedral Mesh Rasterization 

      Gascon, Jorge; Espadero, Jose M.; Perez, Alvaro G.; Torres, Rosell; Otaduy, Miguel A. (ACM SIGGRAPH / Eurographics Association, 2013)
      Many inherently deformable structures, such as human anatomy, are often represented using a regular volumetric discretization, e.g., in medical imaging. While deformation algorithms employ discretizations that deform ...
    • Creature Features: Online motion puppetry for non-human characters 

      Seol, Yeongho; O'Sullivan, Carol; Lee, Jehee (ACM SIGGRAPH / Eurographics Association, 2013)
      We present a novel real-time motion puppetry system that drives the motion of non-human characters using human motion input. We aim to control a variety of creatures whose body structures and motion patterns can differ ...
    • Geodesic Voxel Binding for Production Character Meshes 

      Dionne, Olivier; Lasa, Martin de (ACM SIGGRAPH / Eurographics Association, 2013)
      We propose a fully automatic method for specifying influence weights for closed-form skinning methods, such as linear blend skinning. Our method is designed to work with production meshes that may contain non-manifold ...
    • Virtual Character Performance From Speech 

      Marsella, Stacy; Xu, Yuyu; Lhommet, Margaux; Feng, Andrew; Scherer, Stefan; Shapirok, Ari (ACM SIGGRAPH / Eurographics Association, 2013)
      We demonstrate a method for generating a 3D virtual character performance from the audio signal by inferring the acoustic and semantic properties of the utterance. Through a prosodic analysis of the acoustic signal, we ...
