    • Variational 3D Shape Segmentation for Bounding Volume Computation 

      Lu, Lin; Choi, Yi-King; Wang, Wenping; Kim, Myung-Soo (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      We propose a variational approach to computing an optimal segmentation of a 3D shape for computing a union of tight bounding volumes. Based on an affine invariant measure of e-tightness, the resemblance to ellipsoid, a ...
    • On-the-fly Curve-skeleton Computation for 3D Shapes 

      Sharf, Andrei; Lewiner, Thomas; Shamir, Ariel; Kobbelt, Leif (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      The curve-skeleton of a 3D object is an abstract geometrical and topological representation of its 3D shape. It maps the spatial relation of geometrically meaningful parts to a graph structure. Each arc of this graph ...
    • Boundary Constrained Swept Surfaces for Modelling and Animation 

      You, L. H.; Yang, X. S.; Pachulski, M.; Zhang, Jian J. (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      Due to their simplicity and intuitiveness, swept surfaces are widely used in many surface modelling applications. In this paper, we present a versatile swept surface technique called the boundary constrained swept surfaces. ...
    • Head-eye Animation Corresponding to a Conversation for CG Characters 

      Masuko, Soh; Hoshino, Junichi (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      CG character animations, in which CG characters engage in conversations, are widely used in multimedia contents such as videos and games. In constructing such an animation, we should consider about many factors, such as ...
    • 3D Lip-Synch Generation with Data-Faithful Machine Learning 

      Kim, Ig-Jae; Ko, Hyeong-Seok (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      This paper proposes a new technique for generating three-dimensional speech animation. The proposed technique takes advantage of both data-driven and machine learning approaches. It seeks to utilize the most relevant part ...
    • Context-Aware Skeletal Shape Deformation 

      Weber, Ofir; Sorkine, Olga; Lipman, Yaron; Gotsman, Craig (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      We describe a system for the animation of a skeleton-controlled articulated object that preserves the fine geometric details of the object skin and conforms to the characteristic shapes of the object specified through a ...
    • Prediction of Individual Non-Linear Aging Trajectories of Faces 

      Scherbaum, K.; Sunkel, M.; Seidel, H.-P.; Blanz, V. (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      Represented in a Morphable Model, 3D faces follow curved trajectories in face space as they age. We present a novel algorithm that computes the individual aging trajectories for given faces, based on a non-linear function ...
    • Volume Preservation of Multiresolution Meshes 

      Sauvage, Basile; Hahmann, Stefanie; Bonneau, Georges-Pierre (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      Geometric constraints have proved to be efficient for enhancing the realism of shape animation. The present paper addresses the computation and the preservation of the volume enclosed by multiresolution meshes. A wavelet ...
    • Soft Articulated Characters with Fast Contact Handling 

      Galoppo, Nico; Otaduy, Miguel A.; Tekin, Serhat; Gross, Markus; Lin, Ming C. (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      Fast contact handling of soft articulated characters is a computationally challenging problem, in part due to complex interplay between skeletal and surface deformation. We present a fast, novel algorithm based on a layered ...
    • Skeleton-based Variational Mesh Deformations 

      Yoshizawa, Shin; Belyaev, Alexander; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      In this paper, a new free-form shape deformation approach is proposed. We combine a skeleton-based mesh deformation technique with discrete differential coordinates in order to create natural-looking global shape deformations. ...
    • What can Computer Graphics expect from 3D Computer Vision? 

      Sara, Radim (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      Computer Vision is a discipline whose ultimate goal is to interpret optical images of real scenes. It is well understood that such a problem is cursed by ambiguity of interpretation and uncertainty of evidence. Despite ...
    • Serious Games: Broadening Games Impact Beyond Entertainment 

      Sawyer, Ben (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      Computer and videogames for many years has been an island of technology and design innovation largely left to itself as it morphed from a cottage business into a global media and software industry. While there have been ...
    • Reverse Engineering Nature 

      Jensen, Henrik Wann (The Eurographics Association and Blackwell Publishing Ltd, 2007)
      Why is the sky blue? Why is grass green? What determines the color of human skin? Questions such as these are increasingly important in the development of the next generation algorithms for appearancemodeling in computer ...
