    • EDITORIAL 

      Arnold, David (Blackwell Publishing Ltd and the Eurographics Association, 1990)

    • GosiP: A GKS3D Shell for PHIGS 

      French, Michael (Blackwell Publishing Ltd and the Eurographics Association, 1990)
      Gosip is an implementation of a GKS-3D level 2c interface to PHIGS. It allows GKS applications to run on PHIGS platforms, offering performance and portability across a wide range of high-performance 3D workstations. ...

    • 3D Display: Synthetic Image Generation and Visual Effect Simulation 

      Theoharis, T. A.; Travis, A. R. L.; Wiseman, N. E. (Blackwell Publishing Ltd and the Eurographics Association, 1990)
      Two viewing models are presented for a promising type of three dimensional display: they are based on parallel oblique and perspective oblique projections respectively. A detailed simulation compares the quality of the ...

    • The Implementation of a 2D Convex Hull Algorithm Using Perturbation 

      Day, A.M. (Blackwell Publishing Ltd and the Eurographics Association, 1990)
      This paper discusses the problem of geometric degeneracies and outlines possible solutions when converting geometric algorithms into practice. It concentrates on the application of one of the suggested solutions, a ...

    • A Direct Manipulation Technique for Specifying 3D Object Transformations with a 2D Input Device 

      Van Emmerik, Maarten J.G.M. (Blackwell Publishing Ltd and the Eurographics Association, 1990)
      A mechanism is presented for direct manipulation of 3D objects with a conventional 2D input device, such as a mouse. The user can define and modify a model by graphical interaction on a 3D perspective or parallel projection. ...

    • Simulating Natural Light 

      Wu, Jintong (Blackwell Publishing Ltd and the Eurographics Association, 1990)
      Simulating natural light is an interesting subject in computer graphics. Using the principles of meteorology, we build a sphere cap light source model. Unlike existing illumination or light source models, we consider the ...

    • Durer, Gaskets and Barnsley s Chaos Game 

      Jones, Huw (Blackwell Publishing Ltd and the Eurographics Association, 1990)
      Michael Barnsley has generated the Sierpinski triangle or gasket using his"Chaos Game", a technique for generating random points within a fractal object. Extensions of the method are discussed to generate fractal"gaskets" ...

    • An Efficient Circle-Drawing Algorithm 

      Kuzmin, Yevgeni P. (Blackwell Publishing Ltd and the Eurographics Association, 1990)
      An efficient incremental circledrawing algorithm which uses paired update of the decision variable is proposed. The output of the algorithm is identical to the output of Bresenham s algorithm but the total number of ...
