    • Mappings Between Product Data Definitions 

      Richter, Dieter (The Eurographics Association, 1986)
      It can be observed that existing product data interfaces are constructed by a pragmatic manner. It is not seen any theoretical approach neither for describing nor for evaluating models. In this paper an algebraic approach ...

    • Memory Organization for a Cubic Frame Buffer 

      Kaufman, Arie (The Eurographics Association, 1986)
      A special memory organization of a cubic voxel-based frame buffer is presented. The memory of voxels is divided into n modules of voxels each. The k-th module groups together all the principal diagonal planes within the ...

    • Methods for Cross-Sectional Design of B-Spline Surfaces 

      Woodward, Charles D. (The Eurographics Association, 1986)
      The complexity of free-form surface construction and interaction can often be reduced with methods of crosssectional design. A number of such methods, includin sweeps, skinning and surface interpolation are described in ...

    • Multi-Dimensional Graphics: Algorithms & Applications 

      Inselberg, Alfred (The Eurographics Association, 1986)

    • A Multiple Application Graphics Integrated Circuit - MAGIC 

      Agate, M.; Finch, H.R.; Garel, A.A.; Grimsdale, R.L.; Simmonds, A.C.; Lister, P. F. (The Eurographics Association, 1986)
      MAGIC is a geometry processor which Corms a part of a graphics system based on parallel processing. The number of MAGIC processors required is dictated by the desired system performance. Each unit is capable of controlling ...

    • A Multiprocessor Architecture For High-Quality Interactive Displays 

      Sutherland, Robert J. (The Eurographics Association, 1986)
      A multiprocessor array coupled to a deep framebuffer is proposed as the basis for an interactive user environment of high quality. Several aspects of such an architecture are considered, improvements on previous approaches ...

    • A Pixel-Parallelhidden Surface Algorithm For Constructive Solid Geometry 

      Jansen, Frederik W. (The Eurographics Association, 1986)
      VLSI techniques have greatly enlarged the possibilities to design new frame buffer architectures with parallel processing capabilities down to the pixel level. For these pixel processor systems a parallel hidden surface ...

    • A Portable Graphical Display System For The Partially Sighted 

      DUNLOP, G.R.; B.Sc.,; B.E.(Hons),; Ph.D.,; M.I.E.E.,; C.Elec.Eng., (The Eurographics Association, 1986)
      A portable reading aid based on a graphical display system has been developed for partially sighted persons. This graphical display system incorporates dual microprocessor control of a flat panel AC plasma display and a ...

    • A Quad-Tree Algorithm for Displaying a 2-Dimensional Slice of an N-Dimensional Weighted Voronoi Tessellation 

      Angell, Ian O.; Moore, Richard E.M. (The Eurographics Association, 1986)

    • A Statistical Method For Adaptive Stochastic Sampling 

      Purgathofer, Werner (The Eurographics Association, 1986)
      Stochastic sampling is a good alternative to pure oversampling in terms of image quality. A method for adaptively controlling the number of required samples to the complexity of the picture is presented. The quality of the ...

    • Towards a Formal Specification of the GKS Output Primitives 

      Duce, D. A.; Fielding, E. V. C. (The Eurographics Association, 1986)

    • Towards the Construction of Graphical Interfaces on the Basis of Geometric Models 

      Prospero, Manuel Joao; Messina, Luiz Ary (The Eurographics Association, 1986)
      Dialogue control and dialogue object structures are the outlined concepts developed in this paper. Phases of a CAD-Process are presented to show an outstanding application for the concepts The use of logic programming ...

    • A Version Management System for Design Environments 

      Heine, Thomas Riedel-; Köhler, Dagmar (The Eurographics Association, 1986)
      Design environments for CAD/CAM require new techniques of version management. This work presents a concept of a largely data modelindependent version manager thus allowing easy integration into any existing database system. ...

    • A Visualisation Tool for (Landscape) Architects 

      Lankhorst, Mrs. J. Roos - Klein (The Eurographics Association, 1986)
      In a small and crowded country such as the Netherlands both the government and the individual people are very concerned with what is happening in their environment. Apart from the ecological impacts, the visual effects of ...
