The use of projective geometry in computer graphics by
I Herman(
Book
)
19 editions published between 1991 and 1992 in English and German and held by 493 WorldCat member libraries worldwide
The ultimate goal of all 3D graphics systems is to render 3D objects on a twodimensional surface such as plotter output or a workstation screen. The approach adopted by most graphics systems is to perform a central or parallel projection of the objects onto the view surface. These systems have to make use of the mathematical results of projective geometry. This monograph has as its aim the derivation of a framework for analyzing the behavior of projective transformations in graphics systems. It is shown that a mathematically precise description of the projective geometrical nature of a graphics system leads not only to a deeper understanding of the system but also to new approaches which result in faster or more precise algorithms. A further aim of the book is to show the importance of advanced mathematics for computer science. Many problems become easier to describe or to solve when the appropriate mathematical tools are used. The author demonstrates that projective geometry has a major role to play in computer graphics

PREMO : a framework for multimedia middleware : specification, rationale, and Java binding by
D. J Duke(
Book
)
14 editions published in 1999 in English and held by 455 WorldCat member libraries worldwide
"This book does not attempt to replace the official standard. However, since standards are usually dry, highly technical, and notoriously difficult to read, the authors felt encouraged to provide a more readable version of the basic concepts, to present some of the more important features of the PREMO objects in detail, to highlight the reasons for specific design decisions, and to give simple examples and motivation clarifying the underlying concepts. A particularly helpful feature of the book is that the authors provide detailed specifications of the PREMO objects in Java."Jacket

Computer graphics and mathematics by
B Falcidieno(
Book
)
12 editions published in 1992 in English and held by 229 WorldCat member libraries worldwide
Since its very existence as a separate field within computer science, computer graphics had to make extensive use of nontrivial mathematics, for example, projective geometry, solid modelling, and approximation theory. This interplay of mathematics and computer science is exciting, but also makes it difficult for students and researchers to assimilate or maintain a view of the necessary mathematics. The possibilities offered by an interdisciplinary approach are still not fully utilized. This book gives a selection of contributions to a workshop held near Genoa, Italy, in October 1991, where a group of mathematicians and computer scientists gathered to explore ways of extending the cooperation between mathematics and computer graphics

GKS theory and practice by
Peter R Bono(
Book
)
9 editions published in 1987 in English and held by 216 WorldCat member libraries worldwide
Eurographics, the European Association for Computer Graphics, has always been an important forum for discussions and presentation of results concerning the first ISO Graphical Standard, GKS (the Graphical Kernel System) and later of its threedimensional extension, GKS3D. This book is a collection of those articles which have appeared within the framework of Eurographics in the past 5 years, and which still contain, even after several years, valid and interesting results concerning the problems arising in connection with GKS. Some of these papers help the reader to gain a deeper understanding of the standard; others deal with general implementation problems, and finally there are some presentations of specific algorithms usable also for a GKS or GKS3D implementation. The book may be of a particular interest to those specialists who intend to implement a GKS package or some similar graphics subsystem and who can therefore make direct use of the experiences reflected in this collection. The book should also be a valuable supplement in university courses concerned with teaching the principles of implementing deviceindependent computer graphics

Advances in computer graphics VI by
G Garcia(
Book
)
8 editions published between 1991 and 2013 in English and held by 116 WorldCat member libraries worldwide
This volume is a collection of the Eurographics Tutorials presented at the Eurographics '90 conference in Switzerland. Image synthesis is a traditional topic of Eurographics. But it has become clear in recent years that there is an unnaturally large distance between the two large fields of image synthesis and image analysis  the latter includes such areas as image processing, computer vision, image coding techniques, and 3D reconstruction. There is now a whole range of theoretical problems where the mixture of these two approaches is not only fruitful but also necessary. The spectacular advances in recent years in medical imaging and its applications, in scientific visualization, and in the need for sophisticated input and interaction techniques have all contributed to this development. The tutorial programme of Eurographics '90 was strongly influenced by this development and gives a unique combined perspective on the fields in one volume. The contributors are well known international experts from Europe, Japan and the USA

A dataflow graphics workstation by
P. J. W. ten Hagen(
Book
)
8 editions published in 1989 in English and held by 14 WorldCat member libraries worldwide
Abstract: "A new, revolutionary architecture for a superworkstation for graphical purposes is presented. The architecture is based on the use of advanced graphics components and, mainly, on the heavy use of dataflow processing technology, a still unexplored field of parallel computing as far as graphics is concerned. The resulting initial configuration is able to produce 200.000 to 250.000 Gouraud shaded and Zbuffered 3D triangles in a second with a colour palette of 24 bits per pixels."

The open inventor toolkit and the PREMO standard by
D Wang(
Book
)
6 editions published in 1996 in English and held by 13 WorldCat member libraries worldwide
Abstract: "PREMO is an emerging international standard for the presentations of multimedia objects including computer graphics. Open Inventor [superscript TM] is a commercially available 'de facto' standard for interactive computer graphics packaged as a library of objects. In this paper, we consider whether the concepts and objects of PREMO are sufficient to represent a professional quality system, such as Open Inventor. By comparing PREMO with Open Inventor, we hope to show that PREMO's computer graphics environment model and event model can properly describe Open Inventor's rendering action and event model. The scene graph is very important in Open Inventor. Most Open Inventor functions rely on various operations over scene graphs. The construction, edition and traversal of the scene graphs are implemented as a set of newly defined PREMO objects. Graphics rendering, event handling and scene graphs constitute the fundamental parts of Open Inventor, other Open Inventor functionalities can be constructed from these. We conclude that since these three fundamental parts of Open Inventor can be properly modelled and implemented by means of PREMO, that the concepts and objects of PREMO are sufficient to represent Open Inventor."

On the projective invariant representation of conics in computer graphics by
I Herman(
Book
)
6 editions published in 1989 in English and held by 12 WorldCat member libraries worldwide
Abstract: "A general formulation for conics and conic arcs for the purpose of computer graphics is given, based on principles and theorems of projective geometry. This approach allows the approximation of these curves by line segments to be postponed in the graphics output pipeline; it results in a more compact storage, faster approximation algorithms and smoother outlook of the curves."

Programming paradigms in an objectoriented multimedia standard by
D. J Duke(
Book
)
4 editions published in 1997 in English and held by 11 WorldCat member libraries worldwide
Abstract: "Of the various programming paradigms in use today, objectorientation is probably the most successful in terms of industrial takeup and application, particularly in the field of multimedia. It is therefore unsurprising that this technology has been adopted by ISO/IEC JTC1/SC24 as the foundation for a forthcoming International Standard for Multimedia, called PREMO. Two important design aims of PREMO are that it be distributable, and that it provide a set of mediarelated services that can be extended in a disciplined way to support the needs of future applications and problem domains. While key aspects of the objectoriented paradigm provide a sound technical basis for achieving these aims, the need to balance extensibility and a highlevel programming interface against the realities of efficiency and ease of implementation in a distributed setting meant that the task of synthesising a Standard from existing practice was nontrivial. Indeed, in order to meet the design aims of PREMO it was found necessary to augment the basic object infrastructure with facilities and ideas drawn from other programming paradigms, in particular concepts from constraint management and dataflow. This paper describes the important tradeoffs that have affected the development of PREMO and explains how these are addressed through the use of specific programming paradigms."

Tree visualisation and navigation clues for information visualisation by
I Herman(
Book
)
3 editions published in 1998 in English and held by 11 WorldCat member libraries worldwide
Abstract: "Information visualisation very often requires good navigation aids on large trees, which represent the underlying abstract information. Using trees for information visualisation requires novel user interface techniques, visual clues, and navigational aids. This paper describes a visual clue for trees as well as an automatic folding (clustering) technique, both based on some mathematical concepts and results in combinatorics. Examples are shown how these techniques can be used, and what the further challenges in this area are."
