    • Efficient Lossless Image Contour Coding 

      Turner, Martin J.; Wiseman, Neil E. (Blackwell Science Ltd and the Eurographics Association, 1996)
      A process is presented for converting a raster image into a discrete set of plateaus or contours. A contour coder has been developed which fully describes these contours via their boundary descriptions in a compact and ...

    • Energy Duality Methods for Piecewise Bezier Curve Construction 

      Bercovier, M.; Volpin, O. (Blackwell Science Ltd and the Eurographics Association, 1996)
      Piecewise Bezier Curves are constructed using a minimization principle. Ck and GCk continuity is imposed by linear constraints. The corresponding quadratic programming with linear constraints problem is introduced and ...

    • Functions Defining Arbitrary Meshes - A Flexible Interface between Numerical Data and Visualization Routines 

      Rumpf, Martin; Schmidt, Alfred; Siebert, Kunibert G. (Blackwell Science Ltd and the Eurographics Association, 1996)
      Most of the rendering tools in scientific visualization are restricted to special data structures which differ substantially from the data formats used in numerical applications. Trying to close this gap, we present an ...

    • Incremental Line Labelling for Sketch Input of Solid Models 

      Grimstead, I. J.; Martin, R. R. (Blackwell Science Ltd and the Eurographics Association, 1996)
      Designers need to transfer three-dimensional objects from their minds via a two-dimensional interface into a solid modelling system. We propose a system where objects are sketched interactively in two-dimensions and ...

    • The Layout Design Language: A Technique for Generating Layout Plans 

      Grimsdale, R.L.; Chang, C.W. (Blackwell Science Ltd and the Eurographics Association, 1996)
      The work described in this paper arose from a requirement for a system to support the production of models for training simulator visual systems and other visualisation applications. To reduce the labour involved in ...

    • Pertinent Data for Modelling Pigmented Materials in Realistic Rendering 

      Callet, Patrick (Blackwell Science Ltd and the Eurographics Association, 1996)
      This article discusses the important problem of determining pertinent data to describe a pigmented medium. The first part deals with optical characteristics of pigments and the general properties of binders and fillers. ...
