A Prolog Rule-Based System for cartographic Name Placement
(Blackwell Publishing Ltd and the Eurographics Association, 1990)
Manual name placement is an extremely time consuming task and has been one of the most difficult aspects of the map production process to automate. It is complicated by the large number of rules required for the selection ...
Modelling Clip: Some More Results
(Blackwell Publishing Ltd and the Eurographics Association, 1990)
The modedling clip of the PHIGS ISO Standard is mathematically analysed. The most important result of this analysis is the fact that the projective image of a modding clip body (that is a not necessarily bounded convex ...
Project DIGIS: Building Interactive Applications by Direct Manipulation
(Blackwell Publishing Ltd and the Eurographics Association, 1990)
AbstractDIGIS is a design and implementation system for developers of general purpose interactive applications (IA). It is itself an interactive system that accomplishes its task by Direct Manipulation techniques, in ...
A Browser for Large Directed Graphs
(Blackwell Publishing Ltd and the Eurographics Association, 1990)
The paper describes an experimental graph browsing tool which provides fast interactive browsing on very large graphs. The particular graph for which the program was developed is based on the distributed tile system of a ...
Factoring a Homogeneous Transformation for a more Efficient Graphics Pipeline
(Blackwell Publishing Ltd and the Eurographics Association, 1990)
We identify an intermediate coordinate system situated between world coordinates and display coordinates, which exhibits unique features for lighting calculations and for clipping in homogeneous coordinates. Our key ...
Node Partitioning in an Octree Display Pipeline
(Blackwell Publishing Ltd and the Eurographics Association, 1990)
The node partitioning stage of a graphics pipeline to transform and display octree encoded objects is described. Its function is to accept a sequence of octree node codes, from which the hidden nodes have been removed, and ...
The Douglas-Peucker Algorithm for Line Simplification: Re-evaluation through Visualization
(Blackwell Publishing Ltd and the Eurographics Association, 1990)
The primary aim of this paper is to illustrate the value of visualization in cartography and to indicate that tools for the generation and manipulation of realistic images are of limited value within this application. This ...
Combining Graphics and Windowing Standards in the XGKS System
(Blackwell Publishing Ltd and the Eurographics Association, 1990)
In the past few years we have seen the acceptance of standards for both two and three dimensional computer graphics. Also during this time, the workstation community has converged on a common windowing system. This paper ...
