    • Filtering, Clustering and Hierarchy Construction: a New Solution for Ray-Tracing Complex Scenes 

      Cazals, Frederic; Drettakis, George; Puech, Claude (Blackwell Science Ltd and the Eurographics Association, 1995)
      Data structures that handle very complex scenes (hundreds of thousands of objects) have in the past either been laboriously built by hand, or have required the determination of unintuitive parameter values by the user. It ...
    • Generating a Texture Map from Object-Surface Texture Data 

      Maruya, Makoto (Blackwell Science Ltd and the Eurographics Association, 1995)
      A number of 3D digitizing methods, including stereopsis, are capable of measuring not only an object s shape but also its surface texture. Measured shape data can be expressed as a polyhedron whose faces are triangular, ...
    • A Graph-Based Approach to Surface Reconstruction 

      Mencl, Robert (Blackwell Science Ltd and the Eurographics Association, 1995)
      A new approach to the reconstruction of a surface from an unorganized set of points in space is presented. The point set may for example be obtained with a laser scanner or a manual digitizing tool, and is the only source ...

      We describe the HUMANOID environment dedicated to human modeling and animation for general multimedia, VR, and CAD applications integrating virtual humans. We present the design of the system and the integration of the ...
    • An Incremental Alignment Algorithm for Parallel Volume Rendering 

      Or, Daniel Cohen; Fleishman, Shachar (Blackwell Science Ltd and the Eurographics Association, 1995)
      This paper introduces a data distribution scheme and an alignment algorithm for parallel volume rendering. The algorithm performs a single wrap-around shear transformation which requires only a regular inter-processor ...
    • The MADE Help System 

      Haindl, Michal; de Ruiter, Behr (Blackwell Science Ltd and the Eurographics Association, 1995)
      MADE is the acronym for the ESPRIT project 6307, whose aim is to develop an object oriented multimedia application development environment. As part of this project the MADE help system is designed to be a distributed ...
    • Modeling 3D Curves of Minimal Energy 

      Veltkamp, Remco C.; Wesselink, Wieger (Blackwell Science Ltd and the Eurographics Association, 1995)
      Modeling a curve through minimizing its energy yields an overall smooth curve. A common way to model shape features is to perform the minimization subject to a number of interpolation constraints. This way of modeling is ...
    • Morphological Operations for Color-Coded Images 

      Busch, Christoph and Eberle, Michael (Blackwell Science Ltd and the Eurographics Association, 1995)
      The subject of this paper is the semantically based postprocessing of color-coded images such as classification results. We outline why the classical definition of mathematical morphology suffers if it is used for processing ...
    • A Multimedia Constraint System1 

      van Hintum, J.E.A.; Reynolds, G.J. (Blackwell Science Ltd and the Eurographics Association, 1995)
      The MADE constraint system provides excellent opportunities to introduce constraints in a multimedia application. Multimedia applications are not only a good place to experiment with constraint systems- constraints in a ...
    • Multiresolution B-spline Radiosity 

      Yu, Yizhou; Peng, Qunsheng (Blackwell Science Ltd and the Eurographics Association, 1995)
      This paper introduces a kind of new wavelet radiosity method called multiresolution B-spline radiosity, which uses B-splines of different scales to represent radiosity distribution functions. A set of techniques and ...
    • A new radiosity approach for regular objects: application to ruled surfaces 

      ARQUES, Didier; MICHELIN, Sylvain (Blackwell Science Ltd and the Eurographics Association, 1995)
      This paper introduces a new approach in the radiosity method. The main principle applied here, is the improvement of form factor computation by the knowledge of the model properties. More precisely, if surfaces describing ...
    • Object Calibration for Augmented Reality 

      Whitaker, Ross T.; Crampton, Chris; Breen, David E.; Tuceryan, Mihran; Rose, Eric (Blackwell Science Ltd and the Eurographics Association, 1995)
