Factoring a Homogeneous Transformation for a more Efficient Graphics Pipeline
(Blackwell Publishing Ltd and the Eurographics Association, 1990) Abi-Ezzi, Salim S.; Wozny, Michael J.
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 contribution is an algorithm for extracting such a coordinate system from a homogeneous viewing transformation that relates WC to DC. The algorithm is based on factoring the transformation into a product of a Euclidean factor and a sparse (computationally cheap) but non-Euclidean factor.A particularly strong application of the proposed technique is the graphical processing of curved surface primitives, such as what is needed in the PHIGS PLUS viewing pipeline. Furthermore, in PHIGS PLUS the graphical data is retained by the graphics system, therefore, it is possible to perform the factoring of the viewing transformation at creation time, and to take advantage of this factored form at traversal time.

Project DIGIS: Building Interactive Applications by Direct Manipulation
(Blackwell Publishing Ltd and the Eurographics Association, 1990) Bos, Jan van den; Laffra, Chris
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 principle without using a programming language. DIGIS is a generator in the form of a window-based workbench. It has two input sources. One is a toolkit of predetined interaction tools consisting of prototypes and instances. The other is the set of predetined application procedures thai make up the application part of the IA. The application procedures do not handle user input but may handle textual or graphical screen output. The task of the developer is to build the user interface by selecting the appropriate interaction tools. tailor them to the interface, and tie them to application procedures. This includes the visual representations of interaction tools, their prompts, echoes and feedback. In the process he maps user input to parameter lists for the application procedures, and return parameters to interface output. DIGIS will also support the detinition of composite input (interaction patterns such as sequences). Unix and X are the initiat operating environment, adaption of the input sources to PCTE. OSF/Motif, and Open Look is feasible and anticipated.The design of DIGIS is based on a hierarchical interaction model that is the second focus of this paper. The implementation will be done using PROCOL, a locally developed concurrent object-oriented language. which offers protocols that support composite input. The language is a superset of C, and therefore fully compatible with existing C libraries.ACM Categories and Subject Descriptors: D.2.2 [Software Engineering]: Tools and Techniques -user interfaces, programmer workbench-D.3.3 [Programming Language]: Language Constructs -input/output, programming structures-H.1.2 [Models and Principles]: User/Machine Systems -human factors-1.3.6 [Computer Graphics]: Methodology and Techniques - interaction techniques, ergonomics, languages:
Node Partitioning in an Octree Display Pipeline
(Blackwell Publishing Ltd and the Eurographics Association, 1990) Heal, B.W.
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 to partition it into sets of nodes which are suitable for a multiprocessor rendering stage. Each set is capable of being processed and displayed independently.

A Browser for Large Directed Graphs
(Blackwell Publishing Ltd and the Eurographics Association, 1990) Bovey, J. D.
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 group of workstations but there is no reason why the same techniques should not be used on graphs from other sources.

The Douglas-Peucker Algorithm for Line Simplification: Re-evaluation through Visualization
(Blackwell Publishing Ltd and the Eurographics Association, 1990) Visvalingam, M.; Whyatt, J. D.
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 paper demonstrates the value of visualization within one problem in cartography, namely the generalisation of lines. It reports on the evaluation of the Douglas-Peucker algorithm for line simplification. Visualization of the simplification process and of the results suggest that the mathematical measures of performance proposed by some other researchers are inappropriate, misleading and questionable.

Combining Graphics and Windowing Standards in the XGKS System
(Blackwell Publishing Ltd and the Eurographics Association, 1990) Rogers, Greg; Sung, Kelvin; Kubitz, William
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 discusses the problems encountered in implementing graphics standards such as GKS and PHIGS PLUS within the X Window System environment.

This paper analyses the use of GKS with concurrent languages, showing the inherent problems that arise when working in a multitasking environment. A theoretical solution and its practical implementation are described.
