    • Blowing in the Wind 

      Wei, Xiaoming; Zhao, Ye; Fan, Zhe; Li, Wei; Yoakum-Stover, Suzanne; Kaufman, Arie (The Eurographics Association, 2003)
      We present an approach for simulating the natural dynamics that emerge from the coupling of a flow field to lightweight, mildly deformable objects immersed within it. We model the flow field using a Lattice Boltzmann Model ...
    • 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 ...
    • 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 ...
    • 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 ...
    • Dynapack: Space-Time compression of the 3D animations of triangle meshes with fixed connectivity 

      Ibarria, Lawrence; Rossignac, Jarek (The Eurographics Association, 2003)
      Dynapack exploits space-time coherence to compress the consecutive frames of the 3D animations of triangle meshes of constant connectivity. Instead of compressing each frame independently (space-only compression) or ...
    • Estimating Cloth Simulation Parameters from Video 

      Bhat, Kiran S.; Twigg, Christopher D.; Hodgins, Jessica K.; Khosla, Pradeep K.; Popovic, Zoran; Seitz, Steven M. (The Eurographics Association, 2003)
      Cloth simulations are notoriously difficult to tune due to the many parameters that must be adjusted to achieve the look of a particular fabric. In this paper, we present an algorithm for estimating the parameters of a ...
    • An Evaluation of a Cost Metric for Selecting Transitions between Motion Segments 

      Wang, Jing; Bodenheimer, Bobby (The Eurographics Association, 2003)
      Designing a rich repertoire of behaviors for virtual humans is an important problem for virtual environments and computer games. One approach to designing such a repertoire is to collect motion capture data and pre-process ...
    • An Example-Based Approach for Facial Expression Cloning 

      Pyun, Hyewon; Kim, Yejin; Chae, Wonseok; Kang, Hyung Woo; Shin, Sung Yong (The Eurographics Association, 2003)
      In this paper, we present a novel example-based approach for cloning facial expressions of a source model to a target model while reflecting the characteristic features of the target model in the resulting animation. Our ...
    • Feel the 'Fabric': An Audio-Haptic Interface 

      Huang, G.; Metaxas, D.; Govindaraj, M. (The Eurographics Association, 2003)
      An objective fabric modeling system should convey not only the visual but also the haptic and audio sensory feedbacks to remote/internet users via an audio-haptic interface. In this paper we develop a fabric surface property ...
    • Finite Volume Methods for the Simulation of Skeletal Muscle 

      Teran, J.; Blemker, S.; Hing, V. Ng Thow; Fedkiw, R. (The Eurographics Association, 2003)
      Since it relies on a geometrical rather than a variational framework, many find the finite volume method (FVM) more intuitive than the finite element method (FEM).We show that the FVM allows one to interpret the stress ...
    • Flexible Automatic Motion Blending with Registration Curves 

      Kovar, Lucas; Gleicher, Michael (The Eurographics Association, 2003)
      Many motion editing algorithms, including transitioning and multitarget interpolation, can be represented as instances of a more general operation called motion blending. We introduce a novel data structure called a ...
    • 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 ...
    • 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 ...
    • Geometry Videos: A New Representation for 3D Animations 

      Briceño, Hector M.; Sander, Pedro V.; McMillan, Leonard; Gortler, Steven; Hoppe, Hugues (The Eurographics Association, 2003)
      We present the 'Geometry Video', a new data structure to encode animated meshes. Being able to encode animated meshes in a generic source-independent format allows people to share experiences. Changing the viewpoint allows ...
    • Geometry-Driven Photorealistic Facial Expression Synthesis 

      Zhang, Qingshan; Liu, Zicheng; Guo, Baining; Shum, Harry (The Eurographics Association, 2003)
      Expression mapping (also called performance driven animation) has been a popular method to generate facial animations. One shortcoming of this method is that it does not generate expression details such as the wrinkles due ...
    • 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 ...
