    • 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 ...

    • 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 ...

    • Anisotropic Solid Texture Synthesis Using Orthogonal 2D Views 

      Dischler, J.M.; Ghazanfarpour, D.; Freydier, R. (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      Analytical approaches, based on digitised 2D texture models, for an automatic solid (3D) texture synthesis have been recently introduced to Computer Graphics. However, these approaches cannot provide satisfactory solutions ...

    • Anno 2010 - Remembering Our Future: Challenges and Frontiers of Human-Media Technology as the Kernel for Human-Centered Computing 

      Encarnacao, Jose (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      Based on a forecast by Battelle, Human-Media Technology is one of "technologyâ s top 10 challenges and opportunities" for the year 2010. The subject hereby is: "Humans live, science finds out how technology conforms". The ...

      Unknown author (Blackwell Publishers Ltd and the Eurographics Association, 1998)

    • 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 ...

    • A Collaborative Scene Editor for VRML Worlds 

      Lu, Tain-chi; Chiang, Chuanwen; Lin, Ming-tang; Lee, Chungnan (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      In this paper, we analyze the requirements for a Web-based collaborative infrastructure within a virtual world. Additionally, we combine several tools and methodologies to propose a flexible and fluid collaborative environment ...

    • Colour Illustrations 

      Unknown author (Blackwell Publishers Ltd and the Eurographics Association, 1998)

    • 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 ...

    • The Convergence of Graphics and Imaging 

      Foley, James D. (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      Over twenty years ago a SIGGRAPH panel session addressed the convergence of computer graphics and image processing. At that time the emphasis was on low-level operations such as filtering to avoid anti-aliasing, and related ...

    • Dithered Color Quantization 

      Buhmann, J. M.; Fellner, Dieter W.; Held, M.; Ketterer, J.; Puzicha, J. (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      Image quantization and digital halftoning are fundamental problems in computer graphics, which arise when displaying high-color images on non-truecolor devices. Both steps are generally performed sequentially and, in most ...

    • 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 ...

    • Emotion Editing using Finite Elements 

      Koch, Rolf M.; Gross, Markus H.; Bosshard, Albert A. (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      This paper describes the prototype of a facial expression editor. In contrast to existing systems the presented editor takes advantage of both medical data for the simulation and the consideration of facial anatomy during ...

    • An Enhanced Spring Model for Information Visualization 

      Theisel, Holger; Kreuseler, Matthias (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      In this paper we present a new technique for visualizing multidimensional information. We describe objects of a higher dimensional information space as small closed free-form-surfaces in the visualization. The location, ...

    • Fast Feature-Based Metamorphosis and Operator Design 

      Lee, Tong-Yee; Lin, Young-Ching; Sun, Y.N.; Lin, Leeween (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      Metamorphosis is a powerful visual technique, for producing interesting transition between two images or volume data. Image or volume metamorphosis using simple features provides flexible and easy control of visual effect. ...

    • A Framework for Synchronized Editing of Multiple Curve Representations 

      Grimm, Cindy; Ayers, Matthew (Blackwell Publishers Ltd and the Eurographics Association, 1998)
      Editing curves and surfaces is difficult in part because their mathematical representations rarely correspond to most peopleâ s idea of a curve or surface. The implementation (and hence, behavior) of most manipulation ...
