    • 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 ...

    • 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. ...

    • 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 ...

    • 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 ...
