    • Rendering and Visualization in Affordable Parallel Environments 

      Bartz, Dirk; Silva, Claudio; Schneider, Bengt-Olaf (Eurographics Association, 1998)
      The scope of this full-day tutorial is the use of low and medium-cost parallel environments (less than US $ 60K) for high-speed rendering and visualization. In particular, our focus is on the parallel graphics programming ...

    • 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 ...

    • 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.

    • 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 ...

    • 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 ...

    • 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 ...

    • Interpolation and Approximation of Surfaces from Three-Dimensional Scattered Data Points 

      Mencl, R.; Möller, H. (Eurographics Association, 1998)
      There is a wide range of applications for which surface interpolation or approximation from scattered data points in space is important. Dependent on the field of application and the related properties of the data, many ...

    • 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 ...

    • A Faster Algorithm for 3D Discrete Lines

    • 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)
