THE EFFECTIVENESS OF HIGH-LEVEL GRAPHICAL LANGUAGES IN DEALING WITH VARIOUS GRAPHICAL DOMAINS
(The Eurographics Association, 1982)There are many domains in which graphical programming languages can be applied. Use of a particular graphical programing language will be limited if the domains in which it can be applied are restricted. High-level graphical ... -
A FAST ALGORITHM FOR COLOUR REGION SEGMENTATION
(The Eurographics Association, 1982)An algorithm is described which analyses colour scenes in terms of regions. These regions are defined to have the same 'colour'. In this context the colour of a region is determined by its position in the CIE chromaticity ... -
GENERATING AND PRINTING OF HIGH QUALITY DOCUMENTS IN A DISTRIBUTED OFFICE AUTOMATION NETWORK ENVIRONMENT
(The Eurographics Association, 1982)This paper analyses the process of creating a printed document, which includes text processing, formatting and printing. Corresponding file formats, soft-copy generation algorithms as well as requirements of high quality ... -
GKS in C
(The Eurographics Association, 1982)A binding of GKS, the draft ISO standard for 2D graphics software, to the programming language C is presented, together with the principles underlying its design. The binding is compared with the binding to FORTRAN. An ... -
GRAPH: An Interactive Program based on the Graphical Kernel System
(The Eurographics Association, 1982) -
GRAPHIC DISPLAYS IN THE COMPUTER AIDED DESIGN OF LIFT SYSTEMS
(The Eurographics Association, 1982)The sizing of lift systems to meet passenger demands is normally carried out in a quantitative way by calculation. Nothing is done to determine the quality of service provided. This paper describes how a computer aided ... -
THE IMPORTANCE OF A CORRECT APPROACH TO THE DESIGN OF METAFILES STANDARDS
(The Eurographics Association, 1982) -
INTERACTIVE GENERATION OF 3-DIMENSIONAL COMPUTER GRAPHICS
(The Eurographics Association, 1982)A new technology employing a vibrating mirror produces spacefilling images. An observer views a reflection of a CRT in a moving mirror. By displaying a proper sequence of pictures 30 times a second, a space filling ... -
INTERACTIVE GRAPHICS IN THE ANALYSIS OF PUBLIC UTILITY NETWORKS
(The Eurographics Association, 1982)This paper describes a suite of programs which have been developed in close collaboration with the appropriate public utilities; electricity supply, water and gas industries. The techniques are based on interactive computing ... -
MEASURES OF OPERATOR S VISUAL ACCOMMODATION AND CONVERGENCE TO INFORMATION DISPLAYS
(The Eurographics Association, 1982)Measurements of a display user s lens accommodation and binocular convergence were used to assess the visual impact of display color, display technology, display work time, and display contrast. The studies reported here ... -
A METHODOLOGY FOR POPULATING DEFAULT COLOR MAPS
(The Eurographics Association, 1982)A standard for using colors in computer graphics systems is proposed. A key aspect of this proposed standard is to allow two different levels of access to colors. At the first level, colors are selected from a standard ... -
ON CONSTRUCTING INTERACTIVE GRAPHICS SYSTEMS
(The Eurographics Association, 1982)Abstract: A framework for generating a graphics dialogue system dedicated to special application, user, and graphics hardware characteristics is presented. A prerequisite is the design of common dialogue methods and the ... -
A PACKAGE FOR PROCESSING REMOTE SENSING DATA INTERACTIVELY ON A MINI-COMPUTER SYSTEM
(The Eurographics Association, 1982)A package for the analysis of time sequence remote sensing data is described, which has been designed to run interactively on a mini-computer system utilising colour graphics facilities. The core of the system performs a ... -
PERSPECTIVE MAPPING OF PLANAR TEXTURIS
(The Eurographics Association, 1982)Perspective mapping of planar textures is discussed along two directions. First we study the perspective mapping of a plane onto another plane. We show that the point to point computation involved can be broken down to a ... -
A PRACTICAL STRATEGY FOR CERTIFYING GKS IMPLEMENTATIONS
(The Eurographics Association, 1982)The question of how to validate GKS implementations is crucial to the success of GKS as an international standard for computer graphics. This problem has been addressed by a series of certification workshops sponsored by ... -
THE REPRESENTATION AND USE OF MULTIVARIATE INFORMATION IN GRAPHIC FORM
(The Eurographics Association, 1982) -
SAMMIE-3-D GRAPHICS FOR HUMAN FACTORS APPLICATIONS
(The Eurographics Association, 1982)In the last five years there has become available a wide range of computer aided three dimensional modelling systems, but only one of these has been specifically developed for evaluating human factors aspects of designs, ... -
A SEMANTIC VIEW ON GEOMETRIC REPRESENTATION OF URBAN LAND INFORMATION
(The Eurographics Association, 1982)In this paper we deal with graphical representation of spatially referenced information. We introduce an approach to geometric representation based on the Entity-Attribute-Relationship (EAR)-model. Our object system is an ... -
VISTA VISUAL IMPACT SIMULATION TECHNICAL AID
(The Eurographics Association, 1982)VISTA is a 3-D colour perspective package with hidden surface elimination being developed at the Architecture & Building Aids Computer Unit, Strathclyde (ABACUS). It is an attempt to model the visual reality of both the ... -
WHATEVER HAPPENED TO COMPUTER ART?
(The Eurographics Association, 1982)The way in which computer art has developed over the past fifteen years is discussed and the successes and failures touched upon. Suggestions are made on how computer artists might help in the business of general computer ...
