    • Sound-by-Numbers: Motion-Driven Sound Synthesis 

      Cardle, M.; Brooks, S.; Bar-Joseph, Z.; Robinson, P. (The Eurographics Association, 2003)

    • Constrained Animation of Flocks 

      Anderson, Matt; McDaniel, Eric; Chenney, Stephen (The Eurographics Association, 2003)
      Group behaviors are widely used in animation, yet it is difficult to impose hard constraints on their behavior. We describe a new technique for the generation of constrained group animations that improves on existing ...
    • On Creating Animated Presentations 

      Zongker, Douglas E.; Salesin, David H. (The Eurographics Association, 2003)
      Computers are used to display visuals for millions of live presentations each day, and yet only the tiniest fraction of these make any real use of the powerful graphics hardware available on virtually all of today s machines. ...
    • A Scenario Language to orchestrate Virtual World Evolution 

      Devillers, Frédéric; Donikian, Stéphane (The Eurographics Association, 2003)
      Behavioural animation techniques provide autonomous characters with the ability to react credibly in interactive simulations. The direction of these autonomous agents is inherently complex. Typically, simulations evolve ...
    • Generating Flying Creatures using Body-Brain Co-Evolution 

      Shim, Yoon-Sik; Kim, Chang-Hun (The Eurographics Association, 2003)
      This paper describes a system that produces double-winged flying creatures using body-brain co-evolution without need of complex flapping flight aerodynamics. While artificial life techniques have been used to create a ...
    • Trackable Surfaces 

      Guskov, Igor; Klibanov, Sergey; Bryant, Benjamin (The Eurographics Association, 2003)
      We introduce a novel approach for real-time non-rigid surface acquisition based on tracking quad marked surfaces. The color-identified quad arrangement allows for automatic feature correspondence, tracking initialization, ...
    • A 2-Stages Locomotion Planner for Digital Actors 

      Pettré, Julien; Laumond, Jean-Paul; Siméon, Thierry (The Eurographics Association, 2003)
      This paper presents a solution to the locomotion planning problem for digital actors. The solution is based both on probabilistic motion planning and on motion capture blending and warping. The paper describes the various ...
    • Stylizing Motion with Drawings 

      Li, Yin; Gleicher, Michael; Xu, Ying-Qing; Shum, Heung-Yeung (The Eurographics Association, 2003)
      In this paper, we provide a method that injects the expressive shape deformations common in traditional 2D animation into an otherwise rigid 3D motion captured animation. We allow a traditional animator to modify frames ...
    • A Sketching Interface for Articulated Figure Animation 

      Davis, James; Agrawala, Maneesh; Chuang, Erika; Popovic, Zoran; Salesin, David (The Eurographics Association, 2003)
      We introduce a new interface for rapidly creating 3D articulated figure animation, from 2D sketches of the character in the desired key frame poses. Since the exact 3D animation corresponding to a set of 2D drawings is ...
    • FootSee: an Interactive Animation System 

      Yin, KangKang; Pai, Dinesh K. (The Eurographics Association, 2003)
      We present an intuitive animation interface that uses a foot pressure sensor pad to interactively control avatars for video games, virtual reality, and low-cost performance-driven animation. During an offline training ...
    • Adaptive Wisp Tree - a multiresolution control structure for simulating dynamic clustering in hair motion 

      Bertails, F.; Kim, T-Y.; Cani, M-P.; Neumann, U. (The Eurographics Association, 2003)
      Realistic animation of long human hair is difficult due to the number of hair strands and to the complexity of their interactions. Existing methods remain limited to smooth, uniform, and relatively simple hair motion. We ...
    • Discrete Shells 

      Grinspun, Eitan; Hirani, Anil N.; Desbrun, Mathieu; Schröder, Peter (The Eurographics Association, 2003)
      In this paper we introduce a discrete shell model describing the behavior of thin flexible structures, such as hats, leaves, and aluminum cans, which are characterized by a curved undeformed configuration. Previously such ...
    • Interactive Physically Based Solid Dynamics 

      Hauth, M.; Groß, J.; Straßer, W. (The Eurographics Association, 2003)
      The interactive simulation of deformable solids has become a major working area in Computer Graphics. We present a sophisticated material law, better suited for dynamical computations than the standard approaches. As an ...
    • Handrix: Animating the Human Hand 

      Koura, George El; Singh, Karan (The Eurographics Association, 2003)
      The human hand is a complex organ capable of both gross grasp and fine motor skills. Despite many successful high-level skeletal control techniques, animating realistic hand motion remains tedious and challenging. This ...
    • Construction and Animation of Anatomically Based Human Hand Models 

      Albrecht, Irene; Haber, Jörg; Seidel, Hans-Peter (The Eurographics Association, 2003)
      The human hand is a masterpiece of mechanical complexity, able to perform fine motor manipulations and powerful work alike. Designing an animatable human hand model that features the abilities of the archetype created by ...
