    • 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 ...

    • 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 ...

    • VR-VIBE: A Virtual Environment for Co-operative Information Retrieval 

      Benford, Steve; Snowdon, Dave; Greenhalgh, Chris; Ingram, Rob; Knox, Ian; Brown, Chris (Blackwell Science Ltd and the Eurographics Association, 1995)
      We present a virtual reality application called VR-VIBE which is intended to support the co-operative browsing and filtering of large document stores. VR-VIBE extends a visualisation approach proposed in a previous two ...

    • The MADE Help System 

      Haindl, Michal; de Ruiter, Behr (Blackwell Science Ltd and the Eurographics Association, 1995)
