    A Graphic Programming Environment Based on KADMOS
    (Blackwell Science Ltd and the Eurographics Association, 1992) Dulli, Susi; Milanese, Vitaliano
    In this paper the design and development of a graphic programming system to be relied on KA?MO? are described. The system architecture upresented together with the functionality of construction and manipulation of the geometric entities. The environment provides an homogeneous handling of both 2D and 3D objects, these last being represented in a complete solid modelling scheme. Handling is achieved through a set of operators designed to manipulate geometric entities in a way suitable to hide users the implementation details of the specific representation domain. Prolog has been used as a common language to implement both the geometric entities supported by a hierarchical construction and their shape constraints.

    Formal Specification in the Revision of GKS: An Illustrative Example
    (Blackwell Science Ltd and the Eurographics Association, 1992) Duce, D.A.; Damnjanovic, L.B.
    The first ISO/IEC standard for computer graphics, the Graphical Kernel System (GKS) was published in August 1985. In accordance with ISO/IEC procedures, GKS is now being reviewed and revised. This paper describes how formal specification techniques are being used by the authors to analyse key parts of proposals being made for changes to the framework of GKS to bring the standard into line with the requirements of applications and the operating environment likely to be found in the mid-1990 s.

    A Computer Model For Pinscreen Simulation: A New Animation Paradigm
    (Blackwell Science Ltd and the Eurographics Association, 1992) Lopes, Pedro Faria; Gomes, Mario Rui
    Actual computer image and motion synthesis paradigms are presented in order to introduce a new computer animation paradigm that simulates the traditional pinscreen animation technique. Pinscreen is a very particular and difficult device that enables a"chiaroscuro" approach to image synthesis. The paper describes the traditional pinscreen technique, the way it is operated, results and related difficulties. An extended computer model, including colour and time extensions, to simulate the pinscreen is presented. Results achieved with vector and raster approaches are discussed. Advantages and possibilities of the method when compared with the traditional method and the problems that arise from this technique will also be explained. Finally current and future work is referenced.

    Geometric and Group-theoretic Methods for Computer Graphic Studies of Islamic Symmetric Patterns
    (Blackwell Science Ltd and the Eurographics Association, 1992) Abas, S. J.; Salman, A.
    Over the last several years the authors have used computer graphics to generate, study and analyze more than 300 Islamic geometrical repeat patterns. These patterns offer a rich source for exploitation by artists and are also of interest to mathematicians, crystallographers, architects, archaeologists and others. They can serve as elegant test beds for research into hierarchical programming and texture mapping. The paper discusses the evolution of classical geometric methods for Islamic patterns and goes on to develop algorithms based on group theory for efficient generation of all crystallographic repeat patterns using modern computer graphics.

    Ray Tracing and Graphics Standards
    (Blackwell Science Ltd and the Eurographics Association, 1992) Urban, B.; Haberstroh, T.
    Existing standards for three-dimensional graphic representations are unable to produce any realistically shaded images (except PHIGS PLUS, which provides discrete shading only). Ray Tracing or Radiosity are not taken into account up to this time.This article is intended to show one way to integrate the Ray Tracing technique into the pipeline of the graphics standards GKS-3D and PHIGS. No modifications of the viewing concepts are required by our implementation.

    The Fractal Nature of an Ecological Model
    (Blackwell Science Ltd and the Eurographics Association, 1992) Bennan, Wang; Yin, Shi
    With the help of computer graphics, the chaotic behaviour of an ecological model in the complex plane has been investigated. Convergence maps that show multi-fractal characteristics (science) and beautiful patterns (art) are presented.
