A New General Purpose Method for Large Volume Production of Contour Charts
(Blackwell Publishing Ltd and the Eurographics Association, 1983)
Contour (iso-line) maps are used extensively by the Meteorological Office for both routine and research tasks. The techniques employed in a new FORTRAN subroutine (CMAP) for drawing such maps are described. The algorithm ...
Automatic Contouring of Faulted Seismic Data Sets
(Blackwell Publishing Ltd and the Eurographics Association, 1983)
The theoretical basis for two alternative methods of structuring and then contouring 2D and 3D seismic data with faults is described. Both rely on triangulation systems, but one is more suitable for small memory computers, ...
Graphics Standards: The Pace Quickens
(Blackwell Publishing Ltd and the Eurographics Association, 1983)
In recent months the pace of standards development for computer graphics has quickened. One standard has been adopted, accepted, and has already demonstrated its effectiveness. Another has now achieved the status of Draft ...
UltraPaint: A New Approach to a Painting System
(Blackwell Publishing Ltd and the Eurographics Association, 1987)
The ideas underlying a Painting System being developed at the University of Bath are introduced. This differs from a conventional system in that ultra high definition pictures of upto 1 gigabyte may be created. We discuss ...
Scan Converting Extruded Lines at Ultra High Definition
(Blackwell Publishing Ltd and the Eurographics Association, 1987)
We consider the problem of generating freehand raster graphics pictures at ultra high definition (typically one gigapixel per picture) by scan converting extruded lines. We describe a fast scan conversion algorithm which ...
Architectures of Graphic Processors for Interactive 2D Graphics
(Blackwell Publishing Ltd and the Eurographics Association, 1988)
Interactive 2-D systems have benefited greatly from the improvements in 1C technology. Today, the trend is to relieve the host computer from low level tasks through increasing the graphic system s computational power. The ...
Multiprocessor Ray Tracing
(Blackwell Publishing Ltd and the Eurographics Association, 1986)
A multiprocessor algorithm for ray tracing is described. The performance of the algorithm is analysed for a cubic and square array of processors with only local communication between near neighbours. Theoretical expressions ...
High Performance Colour Displays for Computer Graphics
(Blackwell Publishing Ltd and the Eurographics Association, 1986)
High-performance computer graphics displays for CAD utilize the Shadow-Mask CRT (SMCRT). Factors affecting colour-display quality and ergonomics include beam-to-beam convergence, beamspot profile, resolution, brightness, ...
Interactive Computer Graphics Applied to Chemistry: Experiences and New Developments
(Blackwell Publishing Ltd and the Eurographics Association, 1983)
This paper is essentially a progress report on three years of effort in computer graphics applied to chemistry. The major technical and human problems encountered when running our facility and integrating it into a chemistry ...
The GKS Input Facilities and How To Use Them
(Blackwell Publishing Ltd and the Eurographics Association, 1983)
The input facilities of GKS, the draft international standard for 2-D graphics software, are presented from an application programmer-s viewpoint. The basic concepts are reviewed, concentrating on the differences between ...
