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 ...
A Note on Random Thresholding for Colour Synthesis
(Blackwell Publishing Ltd and the Eurographics Association, 1988)
A simple algorithm that improves colour shaded images is presented. The algorithm does not trade spatial resolution for intensity resolution. The basic technique, based on random thresholding modulated by a pseudo-random ...
A Prolog Environment for GKS-Based Graphics
(Blackwell Publishing Ltd and the Eurographics Association, 1988)
The Prolog language and GK.S are considered in an integrated fashion in order to create a flexible graphics environment. Prolog descriptive properties are devoted to creating hierarchical schemata which can be instantiated ...
Techniques for Animation on Microcomputers
(Blackwell Publishing Ltd and the Eurographics Association, 1988)
Animation is a powerful visualization aid and it has applications not only in the traditional areas of cartoons and fiction movies but also in the study of a wide variety of natural and simulated phenomena. Currently, there ...
Adding Name Sets and Workstation Filters to GKS a Future Extension
(Blackwell Publishing Ltd and the Eurographics Association, 1988)
Construction of Interactive Programs in Computer Graphics
(Blackwell Publishing Ltd and the Eurographics Association, 1988)
In interactive computer graphics, one often finds a gap between sophisticated algorithms, using very high level data structures, and poor methods of program and object construction. Particular programming languages are too ...
A Proposal for a Distributed Model of GKS Based on Prolog
(Blackwell Publishing Ltd and the Eurographics Association, 1988)
The Graphical Kernel System GKS is so well established as a standard for graphics programming that quite a number of models for multiprocessor and distributed environments have already been suggested. It is therefore ...
Planar Convex Hull Algorithms in Theory and Practice
(Blackwell Publishing Ltd and the Eurographics Association, 1988)
Sequential and parallel planar convex hull algorithms, their applications and some of the problems encountered on implementations are described. Details of Pascal implementations are given for three of the sequential ...
A Survey of Computer Animation
(Blackwell Publishing Ltd and the Eurographics Association, 1988)
A survey on computer animation is presented with three specific goals: * .To clarify what people understand by computer animation. * .To separate the different aspects of computer animation and underline its main problems. ...
Some Remarks on the Modelling Gip Problem
(Blackwell Publishing Ltd and the Eurographics Association, 1988)
The modelling clip as proposed for example in PHIGS is mathematically analyzed and a method to perform it is proposed. The method has the particular edvantage of avoiding all possible singularities appearing in the course ...
