    • 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 ...

    • State of the Art in Perceptually Driven Radiosity 

      Prikryl, J.; Purgathofer, W. (Eurographics Association, 1998)
      Despite its popularity among researchers the radiosity method still suffers of some disadvantages over other global illumination methods. Besides the fact that the original method allows only for solving the global ...

    • 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 ...

    • A Faster Algorithm for 3D Discrete Lines 

      Boyer, V.; Bourdin, J. J. (Eurographics Association, 1998)

    • 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 ...

    • 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 ...

    • Multidimensional free-form deformation tools 

      Bechmann, D. (Eurographics Association, 1998)
      A survey of free-form deformation tools where the deformation is controlled by manipulating a 0-D to 3-D tool. Characteristics of a model that includes all these and generalises the concept will be presented.

    • Dynamic Load Balancing in Distributed Virtual Environment 

      Mantler, S.; Schmalstieg, D. (Eurographics Association, 1998)
      -

    • 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 ...

    • Distributed Cooperative Visualization 

      Brodlie, K.W.; Duce, D.A.; Gallop, J.R.; Wood, J.D. (Eurographics Association, 1998)
      Visualization is essentially a collaborative activity, widely used in many scientific and engineering disciplines. Visualization may be used to convey insight into phenomena that are well-understood, or to present new data ...

    • A Standard for Multimedia Middleware 

      Duke, D.J.; Herman, I. (Eurographics Association, 1998)
      Hardware, software, and coding standards for digital media have played a significant role in making multimedia presentation an intrinsic compponent of many systems. However, these standards are primarily concerned with 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.

    • 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 ...

    • A Subdivision Scheme for Smooth Interpolation of Quad-Mesh Data 

      Kobbelt, L. P. (Eurographics Association, 1998)
      A simple interpolatory subdivision scheme for quadrilateral nets with arbitrary topology is presented which generates C1 surfaces in the limit. The scheme satisfies important requirements for practical applications in ...

    • 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 ...

    • Overview of Parallel Photo-realistic Graphics 

      Reinhard, E.; Chalmers, A.G.; Jansen, F.W. (Eurographics Association, 1998)
      Global illumination is an area of research which tries to develop algorithms and methods to render images of artificial models or worlds as realistically as possible. Such algorithms are known for their unpredictable data ...
