COMPUTER AIDED DESIGN LANGUAGE 'CADLAN'
(The Eurographics Association, 1981)
AN APPROACH TO A CALCULATION-MINIMIZED HIDDEN LINE ALGORITHM
(The Eurographics Association, 1981)
Hidden line algorithms based on picture primitives only cannot recognize the areas of a picture completely visible or invisible. By testing each primitive of these areas they produce an overhead of calculations. Moreover ...
A HARDWARE APPROACH TO THE CORE SYSTEM OF ACM/SIGGRAPH
(The Eurographics Association, 1981)
A new structure of the picture generation pipeline for a high-performance vector refresh graphic system is proposed. This pipeline consists of a graphic processor calculating the viewing transformations, a refresh buffer ...
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 ...
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 ...
STATE OF THE ART IN COMPUTER GRAPHICS: A SIGGRAPH PERSPECTIVE
(The Eurographics Association, 1981)
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 user-callable graphics subroutine packages. ...
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 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.
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 ...
