    • A Bernstein-Bezier Based Approach to Soft Tissue Simulation 

      Roth, S.H.; Gross, Markus H.; Turello, Silvio; Carls, Friedrich R. (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      This paper discusses a Finite Element approach for volumetric soft tissue modeling in the context of facial surgery simulation. We elaborate on the underlying physics and address some computational aspects of the finite ...

    • Screen-Space Constraints for Camera Movements: the Virtual Cameraman 

      Jardillier, Frank; Languenou, Eric (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      This article presents a virtual cameraman which allows us to obtain the whole set of camera movements satisfying user defined constraints specified in the image space and/or constraints on the objects of the scene. This ...

    • Conservative Visibility and Strong Occlusion for Viewspace Partitioning of Densely Occluded Scenes 

      Cohen-Or, Daniel; Fibich, Gadi; Halperin, Dan; Zadicario, Eyal (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      Computing the visibility of out-door scenes is often much harder than of in-door scenes. A typical urban scene, for example, is densely occluded, and it is effective to precompute its visibility space, since from a given ...

    • Space Discretization for Efficient Human Navigation 

      Bandi, Srikanth; Thalmann, Daniel (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      There is a large body of research on motion control of legs in human models. However, they require specification of global paths in which to move. A method for automatically computing a global motion path for a human in ...

    • Perception Based Color Image Difference 

      Neumann, Laszlo; Matkovic, Kresimir; Purgathofer, Werner (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      A good image metric is often needed in digital image synthesis. It can be used to check the convergence behavior in progressive methods, to compare images rendered using various rendering methods etc. Since images are ...

    • Accelerated Walkthroughs of Virtual Environments Based on Visibility Preprocessing and Simplification 

      Wang, Yigang; Bao, Hujun; Peng, Qunsheng (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      This paper proposes a new preprocessing method for interactive rendering of complex polygonal virtual environments. The approach divides the space that observer can reach into many rectangular viewpoint regions. For each ...

    • Real-time Biomechanically-based Muscle Volume Deformation using FEM 

      Zhu, Qing-hong; Chen, Yan; Kaufman, Arie (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      This paper presents a voxel-based biomechanical model for muscle deformation using finite element method (FEM) and volume graphics. Hierarchical voxel meshes are reconstructed from filtered segmented muscle images followed ...

    • Molecular Dynamics Simulation in Virtual Environments 

      Ai, Z.; Frohlich, T. (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      A virtual environment for interactive molecular dynamics simulation has been designed and implemented at the Fraunhofer Institute for Computer Graphics. Different kinds of virtual reality devices are used in the environment ...

    • Frontiers in User-Computer Interaction 

      Van Dam, Andries (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      In this age of (near-)adequate computing power, the power and usability of the user interface is as key to an applicationâ s success as its functionality. Most of the code in modern desktop productivity applications resides ...

    • Egocentric Object Manipulation in Virtual Environments: Empirical Evaluation of Interaction Techniques 

      Poupyrev, I.; Ichikawa, T.; Weghorst, S.; Billinghurst, M. (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      The acceptance of virtual environment (VE) technology requires scrupulous optimization of the most basic interactions in order to maximize user performance and provide efficient and enjoyable virtual interfaces. Motivated ...

    • Animation of Biological Organ Growth Based on L-systems 

      Durikovic, Roman; Kaneda, Kazufumi; Yamashita, Hideo (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      In contrast with the growth of plants and trees, human organs can undergo significant changes in shape through a variety of global transformations during the growth period, such as bending or twisting. In our approach, the ...

    • Rapid and Accurate Contact Determination between Spline Models using ShellTrees 

      Krishnan, S.; Gopi, M.; Lin, M.; Manocha, D.; Pattekar, A. (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      In this paper, we present an efficient algorithm for contact determination between spline models. We make use of a new hierarchy, called ShellTree, that comprises of spherical shells and oriented bounding boxes. Each ...

    • Emotion Editing using Finite Elements 

      Koch, Rolf M.; Gross, Markus H.; Bosshard, Albert A. (Blackwell Publishers Ltd and the Eurographics Association, 1998)
