    TOWARDS THE INTEGRATED INTERACTIVE SYSTEM
    (The Eurographics Association, 1980) Newman, William; C. E. Vandoni
    This paper describes the manner in which interactive systems can be expected to develop over the next few years, and discusses some of the implications for design methodology requirements. various influences are seen coming to bear on interactive systems design, causing trends towards integration of function and commonality at the user level. This is seen as bringing about increasing refinement in design methodologies for interactive systems.

    CONSIDERATIONS ON EXTENSIONS OF INPUT FUNCTIONS BASED ON A GRAPHICAL KERNEL SYSTEM
    (The Eurographics Association, 1980) Hillebrand, K.; Weiss, J.; C. E. Vandoni
    The German DIN-Proposal for Graphic Systems provides five classes of input types and three different methods of reading them. In this paper considerations are made on providing a much more powerful interface for the application program than specified in the standard. The basic idea is a user-definable syntax which can be dedicated to every application program under automatic run-time control. One important point is the obviously increased user aid. Last but not least the different implementation methods (central and decentral) are discussed under these aspects.

    TRIAL-AND-ERROR APPLICATIONS FOR INTERACTIVE DATA REPRESENTATION
    (The Eurographics Association, 1980) Vincents, Bo; C. E. Vandoni
    This paper examines the advantages available to planners and experimental theorists of using computers to visualise their theories by generating a multiplicity of graphs interactively. The paper focuses on statistical applications, simulation and differential equation analysis. Examples show how interactive graphing systems can ease the use of complex models by immediately displaying the consequences of trial-and-error assumptions, and by revealing useful interrelationships not predicted by the theory. The paper concludes that applications exist for computer generated graphs in areas where previously hand-drawn graphs have not been practical, such as simulation, regression, estimation and forecasting.

    GENERATION OF COMPLEX 3D FINITE ELEMENT MESHES ON TURNKEY GRAPHIC SYSTEMS
    (The Eurographics Association, 1980) Altimimi, K.; C. E. Vandoni
    This paper outlines a new approach to finite element mesh generation that has been developed at Perkins Engines on a Computervision CADDS III system. Unlike other finite element mesh generation packages, PEPFEM - G (Perkins Engines Package for Finite Elements Mesh Generation) is designed in such a way as to make it possible to <br>a) Generate complex 3D FE meshes with the minimum of data handling by the user. the user of the time consuming task of node numbering and element definition in terms of node numbers.<br>b) The user is free to use all the host graphic system commands in preparing and checking the "drawing" of the mesh.

    SGL - A GENERAL PURPOSE INTERACTIVE SYSTEM BUILT ON TOP OF A GKS IMPLEMENTATION
    (The Eurographics Association, 1980) Cunha, J.D.; C. E. Vandoni
    This paper presents the description of an interactive graphics system built on top of a GKS level 4 implementation. The system architecture is based on the notion of Process and the mainemphasis has been devoted to design a powerful "core", conceived as an extension of the operating system, around which different application programs can be developped with a minimum of effort.

    GRAPHICAL PRESENTATION FOR DATA ANALYSIS IN PARTICLE PHYSlCS EXPERIMENTS : THE HBOOK / HPLOT PACKAGE
    (The Eurographics Association, 1980) Brun, R.; Palazzi, P.; C. E. Vandoni
    HBOOK is a subroutine package to handle statistical distributions (histograms and scatter plots) in a FORTRAN scientific computation environment. It presents results graphically on the line printer, and can optionally draw them on graphic output devices via the HPLOT subpackage.

    SURFACE FITTING BY MEANS OF SPLINES
    (The Eurographics Association, 1980) Brunet, P.; C. E. Vandoni
    Algoritms related with surface interpolation use either global interpolants or local methods. When dealing with irregularly distributed data points, the former are usually cumbersome whereas the later may present continuity problems. In the present paper, a global surface interpolation method is presented. Continuity is assured up to the second partial derivatives, and arbitrarily placed data points are admitted. Complexity of the algorithm is discussed, together with the possibility of interactively varying the interpolant's shape.

    THE DESIGN OF A GENERAL-PURPOSE COMMAND INTERPRETER FOR GRAPHICAL MAN-MACHINE COMMUNICATION TO BE BUILT ON TOP OF A GKS
    (The Eurographics Association, 1980) Borufka, H.G.; Pfaff, G.; C. E. Vandoni
    A model of a general purpose graphical command interpreter (KI) is presented. It is based on the graphical kernel system (GKS) and provides the user with the most common set of commands for solving graphical problems in a dialogue process. Functions for dialogue leading, echoing, error and help messages, editing, and correcting data support interactive working. GKS is demonstrated to be a most suitable graphical basis system for the requirements of the command interpreter. This paper attends to the problems of man-machine communication. Tasks of an operator (as the user or controller of the system) and of an author (as the definator of the application system) as well as the system support of both of them are considered. To adapt the system to the various requirements, tools for extension are provided.

    KISS - AN EXPERIMENT IN THE DESIGN OF IMAGE SYNTHESIS SYSTEMS
    (The Eurographics Association, 1980) GRAVE, M.; C. E. Vandoni
    During the last years, raster graphics have become more and more important, and there is a need in developing a new generation of graphic systems. In this paper a first experiment designed as a "raster extension" to an existing line-drawing system is presented. Some drawbacks of such an extension are shown, and then the main lines of an experimental system, designed around a frame buffer structure, are presented.

    A Low-Cost, Interactive 2D Graphics Package
    (The Eurographics Association, 1980) Ehlers, Bryan L.; C. E. Vandoni
    This paper is a proposal for a low-cost, 2 dimensional graphics design package. Its intent is to provide a naive computer-user with the essential tools of a sophisticated design station while emphasising friendly human-machine interaction. Due to the low-cost nature of the proposed system, certain resolution/speed constraints are considered in the design criteria. These are discussed and reasonable solutions are suggested. The main hardware tools which are used as the foundation of the proposal include the Apple II personal computer and the Apple Graphics Tablet, a new intelligent peripheral recently introduced by Apple.

    Easy to Use Graph Drawing Procedures in ALGOL 68
    (The Eurographics Association, 1980) Butland, S. D.; Butland, J.; Vandoni, C. E.
    An ALGOL68 implementation of a comprehensive set of graph drawing procedures is described. The procedures are designed to enable scientists and engineers writing programs in ALGOL68 to produce a wide range of graphs with little programming effort. The ALGOL68 implementation of the package is compared with the FORTRAN versions and is found to be simpler to use. A description is given of the implementation of the package on a CDC 7600 machine. The package is built on the original FORTRAN subroutines which provide well tested error-free graph drawing software. The programmer, however, only needs to be aware of the much simpler interface provided by ALGOL68.

    GEOGRAPHIC INFORMATION SYSTEMS AND THE ODYSSEY PROJECT
    (The Eurographics Association, 1980) Teicholz, E.; Nisen, B.; C. E. Vandoni
    There are numerous public and private agencies that are currently creating geographic (location specific) data. These agencies include the Census Bureau (County DIME, Urban Atlas, DIME files), the United States Geological Survey (Land Use Series), the Central Intelligence Agency (World Data Banks I and II), NASA (LANDSAT), the Soil Conservation Service (soil surveys) and others. In addition, there are an increasing number of commerical service bureaus offering geographically referenced data. A major problem facing planners, resource analysts, marketing analysts, mathematical geographers and others is the ability to combine these different coverages into a common data base (population, land use, sales areas, zoning districts, etc.), and the ability to comparethese irregular coverages by means of the analytical process of polygon overlay in order to create a composite coverage. This latter task would give the analyst the ability to display a map of, for example, employed persons between the ages of 40 and 50, paying between $2000 and $3000 in real estate taxes and aggregated to congressional districts. The ODYSSEY project of the Harvard Geographic Information System was designed to respond to these problems. ODYSSEY is an open-ended series of program modules that interactively create, manipulate, edit and display geographic data. More specifically, the ODYSSEY programs create data bases by integrating data from a variety of sources, enabling the manipulation of a data base (along with its associated attributes), performing analytic tasks on the data, such as polygon overlay, and displaying the results as colored or black and white thematic maps.

    OPTIMIZED SOFTWARE DISTRIBUTION IN SATELLITE GRAPHICS SYSTEMS
    (The Eurographics Association, 1980) Cullmann, Norbert; C. E. Vandoni
    Interactive computer graphics requires satellite systems. The two software techniques used today with these systems ('fixed-function' and 'programmable satellite') showed to be unsatisfactory. This paper points out refined techniques which are intended to facilitate the programming of a satellite system and to increase its utilization. For this purpose, an optimization is used which delivers the distribution of an application program depending on the host load. Thus, automatic interprocess communication enables a loaddependent floating distribution. This system should also be useful for the distribution of graphical system software like GKS (Graphical Kernel System).

    A CAD - SYSTEM FOR INTERACTIVE GRAPHICAL HANDLING OF HIERARCHICAL BLOCK DIAGRAM INFORMATION
    (The Eurographics Association, 1980) Leinemann, Klaus; C. E. Vandoni
    The CAD - system named GRIMBI is designed to support the functional modelling of large engineering systems. GRIMBI includes a data definition facility, to define model classes functionally and graphically. The data manipulation facility allows for structured modelling by stepwise refinement or abstraction according to known block diagram techniques. Besides batch modelling, GRIMBI supports interactive design by delegating graphic and communication tasks to an intelligent graphic terminal. GRIMBI checks the designer input for validity and completeness.

    IMAGE MODELING ASPECTS OF NON-PROCEDURAL PARALLEL PROCESSING LANGUAGE
    (The Eurographics Association, 1980) Enornoto, Hajime; Yonezaki, Naoki; Miyamura, Isao; C. E. Vandoni
    Fundamental framework of image data modeling for image description and related high level non-procedural language are presented, Structure lines are introduced as invariant features of image to describe structure of images. To specify such structured features and processes to obtain them, we give general principles for non-procedural specification, that is. separation of definition and control. A non-procedural parallel processing language employing this principle is also introduced with examples.

    APPLICATIONS OF AN INTERACTIVE VECTOR GRAPHICS SYSTEM TO CHEMISTRY
    (The Eurographics Association, 1980) WEBER, J.; BERNARDINELLI, G.; COMBREMONT, J.J.; ROCH, M.; C. E. Vandoni
    This paper describes several applications to chemistry of a computer graphics equipment based on a mini-computer and an interactive vector graphics system. After a presentation of the hardware and software available, the following application programs are described and illustrated: (i) 3D visualization of molecular systems, with possible use of a windowing procedure for enlarging part of the structure; (ii) representation of dynamic processes in molecules; (iii) visualization of molecular properties derived from quantum chemical calculations. These applications, which fully exploit the potentialities of the relatively sophisticated equipment, have been developed in order to provide an adequate audio-visual support for teaching chemistry.

    INTERACTIVE COMPUTER GRAPHICS IN COMPUTER-AIDED DECISION ANALYSIS
    (The Eurographics Association, 1980) Carpano, Marie-Jose; Leduc-Leballeur, Andre; C. E. Vandoni
    Two systems for computer-aided decision analysis are presented. In both of them the man-machine communication is achieved through graphical displays. The first one has been designed to facilitate interactive structural systems analysis. It permits us to automatically display a picture of the system on a CRT. The picture has the form of a hierarchized graph with a reasonably small number of edge-crossings. The second one has been conceived for the interactive construction of project networks and subsequent visualization of the critical path.

    COMPUTER GRAPHICS AND ARCHITECTURE
    (The Eurographics Association, 1980) Rogers, Gary; C. E. Vandoni
    Because computer-generated architectural drawings derive from common data bases, they can be more useful than those drawn manually. Beyond viewing functions, other operations (such as financial, spatial, and thermal analyses) can be applied to the computer-based model. The development of relevant input procedures and a coherent theory and methodology for computer aided design will make computer graphics more accessible to architects. This paper describes a continuing effort to accomplish such a development.

    A L G R A , AN ALGEBRAIC-GRAPHIC PROGRAMMING LANGUAGE FOR MODELLING
    (The Eurographics Association, 1980) Kiesewetter, Helmut; C. E. Vandoni
    The programming language ALGRA is based on algebraicgraphic structures. The basic elements of ALGRA are binary formulas of these structures. As compared to DIGRA 73 abstract structural informations may be handled by ALGRA as well as graphical ones. Thus the applicability of ALGRA for abstract modelling is eatablished. Other ingredients of DIGRA 73, like embedding in a host language and prescription of the output process, will be retained. A summary of the main features of ALGRA will be given with special accentuation on modelling processes.

    COMPUTER GRAPHICS APPLIED TO HUMAN MOTION ANALYSIS AND BODY FORCE EVALUATION
    (The Eurographics Association, 1980) Iwata, Kazuaki; Moriwaki, Toshimichi; Kawano, Tsuneo; C. E. Vandoni
    The human body motions during standing up and sitting down from/to a chair are analyzed employing a minicomputer system equipped with a graphic tablet and CRT displays. A two-dimensional mathematical model of the human body is developed and its equa-tions of motions are solved to evaluate forces and torques acting at each body joint. The computer graphics are successfully utilized throughout the study in an interactive manner. The effect of aging upon the body motion is also discussed.

    In this paper we propose a method to implement the moving patterns which are consecutively related in a small computer system. Suppose that the patterns are constructed of many block elements. A pattern is derived by the operation ( such as AND, OR, EXOR, MOVE, ZOOM, ROTATE,. .. ), with another pattern if it is required as operand. The parallel execution on a multiple microprocessor system is also discussed.

    A TV GRAPHICS DISPLAY FOR THE MAN-MACHINE INTERFACE
    (The Eurographics Association, 1980) Anderssen, P.S.; Shering, G.; Stumpe, B.; C. E. Vandoni
    The paper describes a graphical display system based on TV raster scan. Refresh signals to the TV monitors are supplied by a dedicated CAMAC module containing a digital store with one storage element per pixel. The display memory is supported both with firmware in a CAMAC display controller and with s graphics software package in the host computer. The intelligence built into the display controller relieves the host computer from the trivial tasks of the display generation. Combined with the interactive facilities of the NODAL interpreter and special devices for operator input the system offers an easy to use yet flexible interactive graphic display system suitable for industrial control applications.

    F.I.R.S.T., A HIGH RESOLUTION RASTER SCAN DISPLAY SYSTEM FOR INTERACTIVE LAYOUT OF TEXT AND FIGURES
    (The Eurographics Association, 1980) Röthlisberger, H.; Rakotomalala, J.; C. E. Vandoni
    F.I.R.S.T. (Fast Interactive Raster scan workSTation) is designed as a low cost high performance display for interactive applications. Low cost is achieved by using dynamic memories, and high performance implies a high resolution (at least 500x 700) together with fast update rate (an image in a few seconds). Speed is achieved using a distributed architecture; several function generators, such as a character generator and a vector generator, perform the scan conversion. They are connected to the frame buffer by a fast standard pixel bus transmitting one pixel (picture element) in 500 ns. Greyscale or color monitors will require the addition of a few memory planes.

    FAST COLOUR RASTER GRAPHICS USING AN ARRAY PROCESSOR
    (The Eurographics Association, 1980) Walsby, Anthony M.; C. E. Vandoni
    This paper shows how an array processor technique can be used as the basis of an animated (fast) colour raster display. It is amenable to expansion for more colours, greater speed and resolution, and large scale integration techniques because of the regularity and low interconnectivity of an array. This technique could bring the speed and display file advantages of vector graphics to colour raster graphics at a reasonable price.
