    • UltraPaint: A New Approach to a Painting System 

      Watters, Geoff; Willis, Philip (Blackwell Publishing Ltd and the Eurographics Association, 1987)
      The ideas underlying a Painting System being developed at the University of Bath are introduced. This differs from a conventional system in that ultra high definition pictures of upto 1 gigabyte may be created. We discuss ...

    • Scan Converting Extruded Lines at Ultra High Definition 

      Willis, Philip; Watters, Geoff (Blackwell Publishing Ltd and the Eurographics Association, 1987)
      We consider the problem of generating freehand raster graphics pictures at ultra high definition (typically one gigapixel per picture) by scan converting extruded lines. We describe a fast scan conversion algorithm which ...

    • A Scanline Method for Solid Model Display 

      Patel, Manjula; Hubbold, Roger J. (Blackwell Publishing Ltd and the Eurographics Association, 1987)
      The modelling of solid objects is becoming increasingly important in the application of computer graphics to a wide variety of problems, such as CAD/CAM, simulation, and molecular modelling. A variety of methods for rendering ...

    • An Experiment in Algorithm Animation using SMALLTALK on a Macintosh 

      Mohamed, Ramzan (Blackwell Publishing Ltd and the Eurographics Association, 1987)

    • An Economic High Performance Pixel Memory with 3-D Solids Capability 

      Belch, F.R. (Blackwell Publishing Ltd and the Eurographics Association, 1987)
      For economic raster graphics equipment capable of the display of high resolution dynamic pictures of 3-D solids, 3-D wire frames, and 2-D wire frames - in decreasing order of stringency, the design of the pixel memory ...

    • Graphics, Bifurcation, Order and Chaos 

      Pickover, C.A. (Blackwell Publishing Ltd and the Eurographics Association, 1987)
      Chaos theory involves the study of how complicated behaviour can arise in systems which are based on simple rules, and how minute changes in the input of a system can lead to large differences in the output. In this paper, ...

    • Arbitrary Rotation of Raster Images with SIMD Machine Architectures 

      Arabnia, H.R.; Oliver, M.A. (Blackwell Publishing Ltd and the Eurographics Association, 1987)
      An algorithm for the rotation of a raster image by an arbitrary angle is described. The image data structure is closely related to runlength code. The algorithm has been designed to exploit SIMD parallel architectures. It ...

    • Visual Simulation of Atmospheric Haze 

      Willis, P.J. (Blackwell Publishing Ltd and the Eurographics Association, 1987)
      For applications such as daylight visual pilot training simulators, the correct representation of aerial haze, mist and fog is of major importance in providing accurate depth cues and training in poor visibility conditions.We ...

    • Preserving the Area of Regions 

      Williams, Richard (Blackwell Publishing Ltd and the Eurographics Association, 1987)
      When regions are represented by their boundary, the number of points ((x, y) coordinate pairs) used to define the boundary can vary. Many more points are required to satisfactorily display a region at a detailed scale than ...

    • EDITORIAL 

      Arnold, David (Blackwell Publishing Ltd and the Eurographics Association, 1987)

    • A Simple and Efficient Haloed Line Algorithm for Hidden Line Elimination 

      Franklin, W.R; Akman, V. (Blackwell Publishing Ltd and the Eurographics Association, 1987)
      An efficient algorithm, HALO, is given to compute haloed line drawings of wire frame objects. Haloed line drawings are described by Appel et al.1HALO has two parts: CUT and DRAW. CUT uses an adaptive grid to find all edge ...

    • Graphical Interaction Management 

      Barn, Balbir S.; Willis, Philip (Blackwell Publishing Ltd and the Eurographics Association, 1987)
      Graphical interfaces and interactive graphical programmes are awkward to write because of a lack of top-down structure. A methodology for constructing graphical programs will be described, together with a system that ...

    • Graphics in Reservoir Simulation 

      Watkins, Howard K. (Blackwell Publishing Ltd and the Eurographics Association, 1987)
      Reservoir Simulation is used to manage underground oil reservoirs, and the potential cost savings associated with increased oil recovery are enormous. Because of the mathematical complexity of simulation it is necessary ...

    • An Implementer s View of CGM in GKS Environment 

      Moltedo, L.; Noferini, A. (Blackwell Publishing Ltd and the Eurographics Association, 1987)

    • THE CGM - A METAFILE FOR GKS? 

      Brodlie, Ken; Henderson, Lofton; Mumford, Anne (Blackwell Publishing Ltd and the Eurographics Association, 1987)

    • ACM SIGGRAPH 86, Dallas, Texas, 18-22 August 

      Robinson, K. (Blackwell Publishing Ltd and the Eurographics Association, 1987)

    • Using Abstract Data Types To Define Large-scale World Models For Image Generation Systems 

      Marsh, S.C.; Grimsdale, R.L. (Blackwell Publishing Ltd and the Eurographics Association, 1987)
      The creation of databases for real-time image generation systems is expensive and time consuming. This is mostly due to the method of defining the world models which can currently represent an area of up to 500,000 sq Km. ...

    • A User-Interface Toolkit in Object-Oriented PostScript Owen M. Densmore 

      Densmore, Owen M.; Rosenthal, David S. H. (Blackwell Publishing Ltd and the Eurographics Association, 1987)
      Only the diehards want to develop applications using basic window system facilities. The preferred approach is a higher-level"toolkit" of user interface components, such as menus and scroll bars. Experience with current ...
