The Controller Animation System
(Blackwell Publishing Ltd and the Eurographics Association, 1989)
One of the ways in which computer animation can be generated is to use interactive graphics systems. In this paper we describe Controller, an animation system of this type. We concentrate on the operation of Controller and ...
The CGM Today and Tomorrow
(Blackwell Publishing Ltd and the Eurographics Association, 1989)
The Line-Picture Attribute
(Blackwell Publishing Ltd and the Eurographics Association, 1989)
The linetype attribute in GKS and PHIGS is required to cover a wide variety of renderings of the polyline primitive. The results are strongly implementation-dependent, widi virtually no user control. Splitting linetype ...
Developing an Animated Local Network Simulator
(Blackwell Publishing Ltd and the Eurographics Association, 1989)
The Problematics of Human Prototyping and Animation
(Blackwell Publishing Ltd and the Eurographics Association, 1989)
Several ideas and experiments are presented for the creation and realistic animation of three-dimensional scenes involving human beings conscious of their environment. The various approaches should allow the intelligent ...
Two Parallel Methods for Polygon Clipping
(Blackwell Publishing Ltd and the Eurographics Association, 1989)
A control parallel and a novel data parallel implementation of the Sutherland-Hodgman polygon clipping algorithm are presented. The two implementations are based on the INMOS transputer and the AMT Distributed Array Processor ...
A Framework for Functional Specification and Transformation of Hidden Surface Elimination Algorithms
(Blackwell Publishing Ltd and the Eurographics Association, 1989)
This paper deals with the theory of hidden surface elimination algorithms in Computer Graphics. A set of functions and abstract data types are defined to help concisely specify a class of hidden surface elimination algorithms ...
Image Representations Using Miranda Laws
(Blackwell Publishing Ltd and the Eurographics Association, 1989)
The applicative language Miranda is used to define various image representations. One particular feature of this language, an algebraic data type with laws, is shown to be very powerful in giving and automatically maintaining ...
The Incremental Display of a Single-Valued Curve
(Blackwell Publishing Ltd and the Eurographics Association, 1989)
A new algorithm is described for the drawing of a single-valued smooth function on a raster screen. It first approximates the function by a spline, normally cubic, and then displays the spline using a combination of finite ...
Using a Transputer Ring to Transform Raster Images
(Blackwell Publishing Ltd and the Eurographics Association, 1989)
