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 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 ...
Continuous Processing of Images through User Sketched Functional Blocks
(Blackwell Publishing Ltd and the Eurographics Association, 1988)
EUROGRAPHICS General Assembly
(Blackwell Publishing Ltd and the Eurographics Association, 1988)
Dialogue Cell Resource Model and Basic Dialogue Cells
(Blackwell Publishing Ltd and the Eurographics Association, 1988)
A model for the handling of resources used in interactive programs, with emphasis on the input device part, is developed. Its connection to the I/O pair model and its usage in the dialogue cell system is described.The ...
Incremental Polygon Rendering on a SIMD Processor Array
(Blackwell Publishing Ltd and the Eurographics Association, 1988)
We demonstrate how both area coherence and parallelism can be exploited in order to speed up rendering operations on a SIMD square array of processors. Our algorithms take advantage of the method of differences, in order ...
A Top Down Method for Interactive Drawing
(Blackwell Publishing Ltd and the Eurographics Association, 1988)
Traditional interactive drawing programs adopt a bottom-up approach, allowing the user to construct a picture by the use of discrete tools, for example, lines, circles, rectangles, and so on. This paper presents a different ...
A Processor for an Object-Oriented Rendering System
(Blackwell Publishing Ltd and the Eurographics Association, 1988)
An object oriented approach to the real-time rendering of raster images is described. The architecture is based on a set of object processors arranged in a pipeline. These object processors scan convert the objects in the ...
Theoretical Developments on Polygonal Approximation of Parametric Surfaces for Ray Tracing
(Blackwell Publishing Ltd and the Eurographics Association, 1988)
Some theoretical extensions are brought to Koparkar and Mudur s method which deals with a polygonal approximation of parametric surfaces using potential extrema. The proposed extensions allow the determination of both the ...
