  • Kuhme, Thomas; Schneider-Hufschmidt, Matthias (Blackwell Science Ltd and the Eurographics Association, 1992)
    In this paper a brief review of user interface management systems (UIMSs) and their advantages is given. Shortcomings of current UIMSs and open requirements imposed by industrial application areas are outlined. Among the ...
  • Zhou, Tom Z.-Y.; Kubitz, William J. (Blackwell Science Ltd and the Eurographics Association, 1992)
    The object-oriented view of the user interface presented here is a model of object responsibilities-sharing and cooperation for a typical user interface. The model regards the user interface as a three-layer architecture, ...
  • Hsu, Y. H.; Kuo, Y. S. (Blackwell Science Ltd and the Eurographics Association, 1992)
    HAGI is an object-oriented graphics system developed on top of the X window system. In addition to providing facilities that structured graphics systems such as GKS usually have, HAGI supports a high- level graphics paradigm ...

    This paper describes interactive facilities for simulating abstract muscle actions using Rational Free Form Deformations (RFFD). The particular muscle action is simulated as the displacement of the control points of the ...
  • Willis, Philip; Oddy, Robert (Blackwell Science Ltd and the Eurographics Association, 1992)
    We describe an accurate method of rendering by scan-conversion of closed regions bounded by NURBs, with particular comments on its application to computer-based 2D animation. It is shown that the method is fast, analytically ...
  • Krokos, M. A.; Slater, M. (Blackwell Science Ltd and the Eurographics Association, 1992)
    This paper presents a new methodfor providing interactive shape control of interpolating B-splines. The CAD designer can directly interact with geometric entities defined on the B-spline at any interpolated data point- ...
  • Groller, Eduard (Blackwell Science Ltd and the Eurographics Association, 1992)
    Trying to combine fractal geometry and solid modeling seems to be a contradiction in itself, In this paper a new type of 3D objects is presented that accomplishes this combination in a specific way. Objects with a fractal ...
  • Bouras, A.; Shariat, B.; Vandorpe, D. (Blackwell Science Ltd and the Eurographics Association, 1992)
    In this paper, we propose a method of complex curves description, based on the use of standard primitives (curve arcs), inscribed in including boxes. This method simplifies the creation steps (curves are not defined with ...
  • Siltanen, Pekka; Woodward, Charles (Blackwell Science Ltd and the Eurographics Association, 1992)
    Computing an offset curve to a 3D curve involves the basic problem of normal orientation in space. The same thing is encountered when interpolating surfaces with 3D sweep or skinning methods. Different methods for normal ...
  • Kalra, Devendra; Barr, Alan H. (Blackwell Science Ltd and the Eurographics Association, 1992)
    In this paper, we present a general, systematic and consistent treatment of time and events for computer animation. We first formalize the concepts of events and create a time primitive called an event unit. We then present ...
  • Oshima, Tetsuya; Yuasa, Shinji; Sakanoshita, Ken-ichi; Ogata, Yoshinori (Blackwell Science Ltd and the Eurographics Association, 1992)
    We have developed a color CAD system which enables a color designer to evaluate and create body colors of a car on a graphic display and put this system into practical use. The system has three features- generating realistic ...
  • Ma, Lizhuang; Liang, Youdong; Peng, Qunsheng (Blackwell Science Ltd and the Eurographics Association, 1992)
    Smoothing of polyhedron with arbitrary topology is an important issue in CAGD and CAD/CAM, but so far it is deemed to be difficult to smooth the complex corners of a polyhedron. In this paper, the concept of distance ...
  • Falcidieno, Bianca; Ratto, Ornella (Blackwell Science Ltd and the Eurographics Association, 1992)
    This paper discusses the relationships studied between manifold solids and r-sets by defining an r-set as a decomposition in two-manifold cells. This decomposition is represented as a graph (Two-manifold Cell Decomposition ...
  • Haritsis, Angelo; Gillies, Duncan; Williams, Christopher (Blackwell Science Ltd and the Eurographics Association, 1992)
    A simulator has been built to teach doctors the skill of handling a flexible endoscope for gastrointestinal investigations. Trainees use a dummy endoscope in which the control actions are transduced into voltages and sensed ...
  • Chen, M.; Townsend, P.; Wang, C.Y. (Blackwell Science Ltd and the Eurographics Association, 1992)
    Scientists and engineers use numerous kinds of graph notations to model various objects in the real world and their relationships in an abstract pictorial form. However, developing a specific graph editing tool for each ...
  • Holden, E.J.; Roy, G.G. (Blackwell Science Ltd and the Eurographics Association, 1992)
    Signed English is a manual interpretation of English using fingerspelling and signs. A prototype of the Hand Sign Translator (HST) system was developed to graphically translate English into Signed English, using two-handed ...
  • King, Tony (Blackwell Science Ltd and the Eurographics Association, 1992)
    An experimental workstation is described which supports digital video and audio in a distributed environment, and which presents this functionality to the user through the medium of a video-extended implementation of the ...
  • Chrysanthou, Y.; Slater, M. (Blackwell Science Ltd and the Eurographics Association, 1992)
    This paper investigates a new method for dynamically changing Binary Space Partition (BSP) trees. A BSP tree representation of a 3D polygonal scene provides an ideal data structure for rapidly performing the hidden surface ...
  • Pineda, Luis A. (Blackwell Science Ltd and the Eurographics Association, 1992)
    In this paper we discuss two kinds of constraint satisfaction problems that arise in the context of geometric modelling, In particular in the modification of 2-D wire-frame diagrams that are subject to an arbitrary number ...
  • Kok, Arjan J. F.; Jansen, Frederik W. (Blackwell Science Ltd and the Eurographics Association, 1992)
    Ray tracing algorithms that sample both the light received directly from light sources and the light received indirectly by diffuse reflection from other patches, can accurately render the global illumination in a scene ...
