  • Navigation through Virtual 3D Worlds for Facilitating Childrens Spatial Orientation 

    Volbracht, S.; Domik, G. (Eurographics Association, 1998)
    Spatial orientation is an important ability which should be encouraged in geometry courses of elementary schools. A preferred approach (in Germany) typically involves navigation and wayfinding tasks with pictures of a town ...
  • A Semi-empirical Model for the Representation of Materials in Photorealistic Rendering 

    Hansmann, W.; Warncke, H. (Eurographics Association, 1998)
    From the beginning of Computer Graphics various models intended to describe the optical properties of different materials have been proposed. Some of these models are purely empirical [1]. Others are very close to physics ...
  • Virtual Sewing System for Apparel Design 

    Soo Suh, Y.; Endou, Y.; Gotoh, D.; Kiyota, A.; Okabe, H.; Niwaya, H.; Shigeru, I. (Eurographics Association, 1998)
    An apparel CAD system capable of 3D simulation of clothes is reported. The system works on personal computers, has graphical user interface and requires minimal input to indicate how to sew and put on the dress. The system ...

  • Modelling Cloth Buckling and Drape 

    Dias, J.M.S.; Gamito, M.N.; Rebordao, J.M. (Eurographics Association, 1998)
    We present a new computational model for plain woven fabrics. The model is able to represent known elastic behaviour in deformation, such as planar extension and shearing and out-of-plane bending, drape and buckling. The ...
  • Agents in multi-user virtual environments 

    Paul, Christian; Peters, Ralph; Graeff, Andreas (Eurographics Association, 1998)
    In this paper,we introduce the use of agents in combinationwith virtual realities as one possibility to enhancefuture communication systems.These agents support the user and his/her interactionwith objects within the virtual ...
  • Using constraints to describe high-level behaviours in virtual worlds 

    Richard, N.; Codognet, P.; Grumbach, A. (Eurographics Association, 1998)
    Our aim is to make the authoring of virtual worlds easier for non-specialists, in particular when programming pseudo-intelligent agents within virtual environments.We are designing a high-level language as well as a library ...
  • Face-to-Face Communication System in Cyberspace by Voice Driven Avatar 

    Morishima, S.; Yotsukure, T.; Fuji, E. (Eurographics Association, 1998)
    Recently computer can make cyberspace to walk through by an interactive virtual reality technique. An avatar in cyberspace can bring us a virtual face-to-face communication environment. In this paper, we realize an avatar ...
  • A Faster Algorithm for 3D Discrete Lines

  • Motion Reparametrization 

    da Silva, F.W.; Velho, L.; Gomes, J. (Eurographics Association, 1998)
    This paper presents an algorithm for reparametrization of 1D signals in the discrete domain, according to a userdefined velocity function. The application outlined in this work is the reparametrization of joint curves ...

  • Visualization of Dynamic Processes Recorded during Epileptic Seizures 

    Dillenseger, J.L.; Wendling, F. (Eurographics Association, 1998)
    A visualization system dedicated to the analysis of spatio-temporal dynamics of epileptic processes recorded by stereoeletroencephalography (SEEG) is presented. It is based on the representation in a same anatomical scene ...
  • Scanning and Reconstruction of human body parts 

    Borghese, N.A.; Ferrari, S. (Eurographics Association, 1998)
    The reconstruction of 3D models of human body parts from range data is different with respect to that of general objects as they do not exhibit sharp discontinuities. Following this consideration, HRBF models which implement ...
  • Comparison between two Three-Dimensional Edge Operators applied in a 3D Navigation Approach 

    Dillenseger, J.L.; Sousa Santos, B. (Eurographics Association, 1998)
    This paper will compare two 3D surface detection and normal estimation operators applied on a rough voxel database. These approaches can be applied as virtual endoscopy for the exploriation of 3D medical image volumes. The ...
  • Immersive High Quality Communication 

    Gräff, A.; Schiffner, N. (Eurographics Association, 1998)
    This shows our vision of advanced high quality tele-communication which can be achieved by combining large-scale displays, real-time audio/video transmission, virtual reality and global, high bandwidth computer networks.
  • Behavior Authoring for VRML Applications in Industry 

    Dörner, R.; Elcacho, C.; Luckas, V. (Eurographics Association, 1998)
    As VRML offers behavior definition on different levels (animation behavior, interaction behavior, hypermedia behavior, application behavior) an authoring tool for VRML content creation has to comprise a dedicated behavior ...

  • The Hidden Face Determination Tree 

    James, A.; Day, A.M. (Eurographics Association, 1998)
    Hidden surface removal can be achieved using the Priority Face Determination (PFD) tree to create a priority ordering of n polygons in log4=3 n time. In this paper, we describe the Hidden Face Determi- nation (HFD) tree ...
