  • An Efficient Adaptive Algorithm for Constructing the Convex Differences Tree of a Simple Polygon 

    Rappoport, Ari (Blackwell Science Ltd and the Eurographics Association, 1992)
    The convex differences tree (CDT) representation of a simple polygon is useful in computer graphics, computer vision, computer aided design and robotics. The root of the tree contains the convex hull of the polygon and ...

  • A New Two Dimensional Line Clipping Algorithm for Small Windows 

    Day, J. D. (Blackwell Science Ltd and the Eurographics Association, 1992)
    A new algorithm for clipping lines against rectangular windows is described. It is suitable for computations in both object space (floating point arithmetic) and image space (integer arithmetic). The algorithm is compared ...

  • X: Why Z? 

    Bowen, Jonathan P. (Blackwell Science Ltd and the Eurographics Association, 1992)
    Window management systems are now used extensively for user interfaces to computer systems. In particular, X11 has come to dominate the workstation market as a widely accepted industry standard on many different hardware ...

  • Performance of Space Subdivision Techniques in Ray Tracing 

    McNeill, M. D. J.; Shah, B. C.; Hebert, M.-P.; Lister, P. F.; Grimsdale, R. L. (Blackwell Science Ltd and the Eurographics Association, 1992)
    Whilst providing images of excellent quality, ray tracing is a computationally intensive task. The first part of this paper compares the speed-up achieved in ray tracing using various space subdivision algorithms and ...

  • Combined Direct and Inverse Kinematic Control for Articulated Figure Motion Editing 

    Boulic, Ronan; Thalmann, Daniel (Blackwell Science Ltd and the Eurographics Association, 1992)
    A new approach for the animation of articulated figures is presented. We propose a system of articulated motion design which offers a full combination of both direct and inverse kinematic control of the joint parameters. ...

  • Consistent Schemes for Addressing Surfaces when Ray Tracing Transparent CSG Objects 

    Gervautz, Michael (Blackwell Science Ltd and the Eurographics Association, 1992)
    Constructive Solid Geometry (CSG) defines the shape of objects, i.e. the inside and the outside regions of objects, but it does not define the material properties of the space in the interior of objects. The definition is ...
