CAPITOL : A LOW COST 3D MODELLING AND VISUALIZATION SYSTEM FOR INTERIOR DESIGNERS AND ARCHITECTS
(The Eurographics Association, 1981)The CAPITOL system aims to provide a flexible but low cost 3D modelling and visualization system which can be used as an integral part of the creative aesthetic and visual design process by interior designers and architects. ... 
COMPUTER AIDED DESIGN LANGUAGE 'CADLAN'
(The Eurographics Association, 1981) 
Computer Graphics for Federal Planning in WestGermany
(The Eurographics Association, 1981)To satisfy the cartographic requirements for spatial analysis, planning and forecast on the federal level in West Germany the Federal Research Institute for Regional Geography and Regional Planning established a system for ... 
EXPERIENCES IN THE DESIGN AND SUPPORT OF A GRAPHICS DEVICE DRIVER INTERFACE
(The Eurographics Association, 1981)The Common Graphics System (CGS) was developed at the Los Alamos National Laboratory. A standard device driver interface was defined for graphics device drivers and for use by usercallable graphics subroutine packages. ... 
EXTRACTING LINE MAPS FROM IMAGES
(The Eurographics Association, 1981)We present methods to vectorize automatically information given in raster form, the algorithms used are discussed briefly, and results for some test cases are presented. The compression of information is discussed as well ... 
FAST INTERACTIVE GRAPHIC ANALYSIS AND PRESENTATION OF IRREGULARLY SPACED LATA z(x,y)
(The Eurographics Association, 1981)This is a method to be applied in R&D. 1. A surface is generated, containing exactly all given points z(x,y). 2. The degree of accuracy is gradually specified. One can swap 'ACCURACY for SPEED'. 3. 'Out of the picture' ... 
THE GEOMETRIC WORKBENCH (GWB)  AN EXPERIMENTAL GEOMETRIC MODELING SYSTEM
(The Eurographics Association, 1981)The Geometric workbench (GWB), an experimental. geometric modeling system, is described. It is based on a hybrid representation scheme, where solids are represented by CSG volume trees and boundary representations. Boundary ... 
A GKS IMPLEMENTATION FOR METEOROLOGICAL APPLICATIONS
(The Eurographics Association, 1981)In this paper we describe a GKS implementation made at ECMWF and we point out some problems encountered related to the definition of GKS 6.2 and to the necessity to adapt to the meteorogical applications. 
A GKS INTERFACE TO A REALTIME ORIENTED RASTER WORKSTATION FOR CAD APPLICATIONS
(The Eurographics Association, 1981)The interface of the Graphical Kernel System GKS is examined with respect to the demands of realtime raster graphics. First the computation time for the different transformations is estimated, to show the great gap between ... 
Graphics Standards  Where are we ?
(The Eurographics Association, 1981)An overview is given of the state of the standardization efforts of ISO/TC97/SC5/WG2, which currently concentrate on GKS. The standardization activities are illustrated by presenting a recently incorporated concept of ... 
A HARDWARE APPROACH TO THE CORE SYSTEM OF ACM/SIGGRAPH
(The Eurographics Association, 1981)A new structure of the picture generation pipeline for a highperformance vector refresh graphic system is proposed. This pipeline consists of a graphic processor calculating the viewing transformations, a refresh buffer ... 
THE HIGHLEVEL GRAPHICS PROGRAMMING LANGUAGE PASCAL/GRAPH
(The Eurographics Association, 1981)A highlevel programming language like PASCAL offers data types, variables, constants and operators, by which the programmer can reflect the actual world as a model inside the computer. The world of numbers and text has ... 
THE IMPACT OF COMPUTER GRAPHICS ON INDUSTRIAL PRODUCT DEVELOPMENT
(The Eurographics Association, 1981) 
MOVIE.BYU  1981
(The Eurographics Association, 1981)MOVIE.BYU facilitates the display of threedimensional mathematical, topological, and architectural models as line drawings or as continuous tone shaded images. This software provides the capability to clip and cap three ... 
A NEW METHOD FOR LOCAL SMOOTH INTERPOLATION
(The Eurographics Association, 1981)A new method for interpolation is presented which starts from a given set of data pints. The resulting curve consisting of a set of polynomials has tangent vector continuity in the nodes, and can have straight line sections ... 
A Revolution in Hardware Systems Design and its Implications for the Graphics Community
(The Eurographics Association, 1981) 
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 online 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 MIRA2D, 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
