      Li, Yi; Christie, Marc; Siret, Orianne; Kulpa, Richard; Pettré, Julien (The Eurographics Association, 2012)
      This paper introduces a method to clone crowd motion data. Our goal is to efficiently animate large crowds from existing examples of motions of groups of characters by applying an enhanced copy and paste technique on them. ...
    • Combining Marker-based Mocap and RGB-D Camera for Acquiring High-fidelity Hand Motion Data 

      Zhao, Wenping; Chai, Jinxiang; Xu, Ying-Qing (The Eurographics Association, 2012)
      Motion capture data has been pivotal to the success of creating realistic animation for human characters. There are a number of public full-body motion databases available, but large and heterogeneous databases for hand ...
    • Component-based Locomotion Composition 

      Kim, Yejin; Neff, Michael (The Eurographics Association, 2012)
      When generating locomotion, it is particularly challenging to adjust the motion's style. This paper introduces a component-based system for human locomotion composition that drives off a set of example locomotion clips. ...

      Raveendran, Karthik; Thuerey, Nils; Wojtan, Chris; Turk, Greg (The Eurographics Association, 2012)

      Taylor, Sarah L.; Mahler, Moshe; Theobald, Barry-John; Matthews, Iain (The Eurographics Association, 2012)
      We present a new method for generating a dynamic, concatenative, unit of visual speech that can generate realistic visual speech animation. We redefine visemes as temporal units that describe distinctive speech movements ...
    • Efficient Collision Detection for Brittle Fracture 

      Glondu, Loeiz; Schvartzman, Sara C.; Marchal, Maud; Dumont, Georges; Otaduy, Miguel A. (The Eurographics Association, 2012)
      In complex scenes with many objects, collision detection plays a key role in the simulation performance. This is particularly true for fracture simulation, where multiple new objects are dynamically created. In this paper, ...
    • Efficient Composition for Virtual Camera Control 

      Lino, Christophe; Christie, Marc (The Eurographics Association, 2012)
      Automatically positioning a virtual camera in a 3D environment given the specification of visual properties to be satisfied (on-screen layout of subjects, vantage angles, visibility) is a complex and challenging problem. ...
    • Efficient Simulation of Example-Based Materials 

      Schumacher, Christian; Thomaszewski, Bernhard; Coros, Stelian; Martin, Sebastian; Sumner, Robert; Gross, Markus (The Eurographics Association, 2012)
      We present a new method for efficiently simulating art-directable deformable materials. We use example poses to define subspaces of desirable deformations via linear interpolation. As a central aspect of our approach, we ...
    • Energetically Consistent Invertible Elasticity 

      Stomakhin, Alexey; Howes, Russell; Schroeder, Craig; Teran, Joseph M. (The Eurographics Association, 2012)
      We provide a smooth extension of arbitrary isotropic hyperelastic energy density functions to inverted configurations. This extension is designed to improve robustness for elasticity simulations with ex- tremely large ...
    • Enriching Coarse Interactive Elastic Objects with High-Resolution Data-Driven Deformations 

      Seiler, Martin; Spillmann, Jonas; Harders, Matthias (The Eurographics Association, 2012)
      Efficient approximate deformation models allow to interactively simulate elastic objects. However, these approaches usually cannot reproduce the complex deformation behavior governed by geometric and material nonlinearities. ...
    • Environment-aware Real-Time Crowd Control 

      Henry, Joseph; Shum, Hubert P. H.; Komura, Taku (The Eurographics Association, 2012)
      Real-time crowd control has become an important research topic due to the recent advancement in console game quality and hardware processing capability. The degrees of freedom of a crowd is much higher than that provided ...
    • Evaluating the Plausibility of Edited Throwing Animations 

      Vicovaro, Michele; Hoyet, Ludovic; Burigana, Luigi; O'Sullivan, Carol (The Eurographics Association, 2012)
      Animation budget constraints during the development of a game often call for the use of a limited set of generic motions. Editing operations are thus generally required to animate virtual characters with a sufficient level ...
    • Faster Acceleration Noise for Multibody Animations using Precomputed Soundbanks 

      Chadwick, Jeffrey N.; Zheng, Changxi; James, Doug L. (The Eurographics Association, 2012)
      We introduce an efficient method for synthesizing rigid-body acceleration noise for complex multibody scenes. Existing acceleration noise synthesis methods for animation require object-specific precomputation, which is ...
