SGL APPLICATION - DEFINITION AND PRACTICAL USE
(The Eurographics Association, 1981)This paper describes our experience in the development of an application using the SGL system presented in previous publications ( [2] [3] ). Special attention is paid to the pos sibilities and limitations due to GKS ... -
SMOOTHING A DIGITIZED CURVE BY DATA REDUCTION METHODS
(The Eurographics Association, 1981)In order to reduce storage and subsequent processing costs for a digitized cartographic curve, we may wish to reduce the data set. The data reduction method which is described in this paper, can be used on-line during the ... -
SOME USEFUL BUT RATHER UNUSUAL GRAPHICAL PRIMITIVES
(The Eurographics Association, 1981)The MIRALIB library is a powerful graphical library which may be used with MIRA-2D, a graphical PASCAL extension as well as with the standard PASCAL language. MIRALIB includes figure algebra routines, figure measure ... -
STATE OF THE ART IN COMPUTER GRAPHICS: A SIGGRAPH PERSPECTIVE
(The Eurographics Association, 1981) -
TELIDON: WHERE VIDEOTEX MEETS COMPUTER GRAPHICS
(The Eurographics Association, 1981)Videotex is a system by which information can be accessed from central data bases by the general public. By the use of a television receiver augmented by a micro-computer controlled interface device, a user can access pages ... -
TIME AND SPACE BOUNDS FOR HIDDEN LINE AND HIDDEN SURFACE ALGORITHMS
(The Eurographics Association, 1981)Asymptotic worst case time bounds for three hidden line algorithms are derived and analysed. The first algorithm is a brute force solution that needs at least quadratic time. The second exact hidden line algorithm is based ... -
TOWN PLANNING AIDED BY AN INTEGRATED MUNICIPAL LAND INFORMATION SYSTEM
(The Eurographics Association, 1981)The purpose of this paper is to describe the results of our recent land information systems research in The Institute of Geodesy at Helsinki University of Technology. Our goal is to make research on municipal systems by ... -
THE USE OF STANDARD GRAPHICS SOFTWARE IN THE STARLINK IMAGE PROCESSING FACILITY
(The Eurographics Association, 1981)Starlink is a network of powerful interactive minicomputers, for use by astronomers in the UK; these computers run common software distributed from a central node. The use of standard general purpose graphics software in ... -
USER GUIDANCE IN INTERACTIVE SYSTEMS - THE ROLE OF GRAPHICAL FEATURES
(The Eurographics Association, 1981)Users of technical systems become increasingly involved in computer controlled dialogues of various forms. One kind of dialogue is of the interrogative form based on the exchange of alphanumeric and symbolic strings via ... -
VOICE RECOGNITION IN A GRAPHIC SYSTEM
(The Eurographics Association, 1981)Voice recognition is discussed as a useful tool in interactive graphics. Two applications in electronical design and surveying are described. First results show an increased input speed, a low error probability and more ...
