  • 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 ...
  • 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 ...

    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 ...
  • 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 ...
  • 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 ...
  • Differential Blending for Expressive Sketch-Based Posing 

    Öztireli, A. Cengiz; Baran, Ilya; Popa, Tiberiu; Dalstein, Boris; Sumner, Robert W.; Gross, Markus (ACM SIGGRAPH / Eurographics Association, 2013)
    Generating highly expressive and caricatured poses can be difficult in 3D computer animation because artists must interact with characters indirectly through complex character rigs. Furthermore, since caricatured poses ...
  • One-to-Many: Example-Based Mesh Animation Synthesis 

    Zheng, Changxi (ACM SIGGRAPH / Eurographics Association, 2013)
    We propose an example-based approach for synthesizing diverse mesh animations. Provided a short clip of deformable mesh animation, our method synthesizes a large number of different animations of arbitrary length. Combining ...
  • SPREAD : Sound Propagation and Perception for Autonomous Agents in Dynamic Environments 

    Huang, Pengfei; Kapadia, Mubbasir; Badler, Norman I. (ACM SIGGRAPH / Eurographics Association, 2013)
    The perception of sensory information and its impact on behavior is a fundamental component of being human. While visual perception is considered for navigation, collision, and behavior selection, the acoustic domain is ...
  • Multi-Domain Real-time Planning in Dynamic Environments 

    Kapadia, Mubbasir; Beacco, Alejandro; Garcia, Francisco; Reddy, Vivek; Pelechano, Nuria; Badler, Norman I. (ACM SIGGRAPH / Eurographics Association, 2013)
    This paper presents a real-time planning framework for multicharacter navigation that enables the use of multiple heterogeneous problem domains of differing complexities for navigation in large, complex, dynamic virtual ...
  • Velocity-Based Modeling of Physical Interactions in Multi-Agent Simulations 

    Kim, Sujeong; Guy, Stephen J.; Manocha, Dinesh (ACM SIGGRAPH / Eurographics Association, 2013)
    We present an interactive algorithm to model physics-based interactions in multi-agent simulations. Our approach is capable of modeling both physical forces and interactions between agents and obstacles, while allowing the ...
  • 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 ...

    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 ...
  • 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 ...
