Web Design - New design for web sites in a commercial context
(Eurographics Association, 1997) Barfield, Lon
The web is a completely new medium and is rapidly taking its place alongside existing media such as television, telephone, CD-ROMS, etc. Any new media requires a new approach to design. How do the advances in the web compare to the historical advances in other media, and what are the factors that play a key role in the design of web sites? It is not just the medium that is developing rapidly, the market is also changing. This is leading to new approaches to the role that the web plays in communication with the public and within organisations.
Digital Publishing - Data Handling
(Eurographics Association, 1997) MacIntyre, Ross
SuperJournal is a research project aiming to identify what factors will make electronic journals successful and why. The project brings together some 20 society, university press and commercial publishers, who are providing electronic versions of around 50 journal titles in discrete areas of academic research. The “why?” is being established via a formal evaluation study being conducted by Loughborough University. In order to undertake the study, an application is being developed by the University of Manchester which offers choice over both content and functionality to the users, who are based at targeted universities. This report focuses on the technical development work undertaken so far to support the scalable distribution of digital journals in an academic network environment. University of Manchester receives data files from the different publishers in a variety of formats: principally SGML, HTML, PDF and PostScript, plus GIF, TIFF and EPS; and via various transfer mechanisms. All SGML is ‘synthesised’ to conform to a DTD defined by the project, converted to HTML including enhancement. The associated scalability issues are discussed. Data is loaded into a number of datastores: an objectbase, a relational database and application-specific databases; and indexed via a number of search engines. The application is accessed over the WWW and consists of an integrated assembly of software, providing the core functionality to maximise use, e.g. searching, browsing, linking, screen presentation and personal preference setting.
Advanced Applications of Volume Visualization Methods in Medicine
(Eurographics Association, 1997) Sakas, Georgios; Pommert, Andreas
Tomographicmedical imaging techniques have become more popular in recent years. The wide availability of CT,MRI and Ultrasound inmost large hospitals results in a rapidly increasing number of examinations with these devices. The State of The Art Report summarises the application of techniques developed over the recent years for visualising volumetric medical data common in modern medical imaging modalities such as CT, MRA, MRI, Nuclear Medicine, 3D-Ultrasound, Laser Confocal Microscopy etc. Although all of the modalities listed above provide ”slices of the body”, significant differences exist between the image content of each modality. The focus of the Report is be less in explaining algorithms and rendering techniques, but rather to point out their applicability, benefits, and potential in the medical environment. In the first part, methods for all steps of the volume visualization pipeline from data preprocessing to object display are reviewed, with special emphasis on data structures, segmentation, and surface- and volume-based rendering. Furthermore,multimodalitymatching, interventionrehearsal, and aspects of image quality are discussed. In the second part applications are illustrated fromthe areas of craniofacial surgery, traumatology, neurosurgery, radiotherapy, and medical education. Furtherly, some new applications of volumetricmethods are presented: 3D ultrasound, laser confocal datasets, and 3D-reconstruction of cardiological datasets, i.e. vessels as well as ventricles. These new volumetric methods are currently under development but due to their enormeous application potential they are expected to be clinically accepted within the next years.
On the Computational Requirements of Virtual Reality Systems
(Eurographics Association, 1997) Dévai, Frank
The computational requirements of high-quality, real-time rendering exceeds the limits of generally available computing power. However illumination effects, except shadows, are less noticeable on moving pictures. Shadows can be produced with the same techniques used for visibility computations, therefore the basic requirements of real-time rendering are transformations, pre-selection of the part of the scene to be displayed and visibility computations. Transformations scale well, ie, their time requirement grows linearly with the input size. Pre-selection, if implemented by the traditional way of polygon clipping, has a growing rate of N logN in the worst case, where N is the total number of edges in the scene. Visibility computations, exhibiting a quadratic growing rate, are the bottleneck from a theoretical point of view. Three approaches are discussed to speed up visibility computations: (i) reducing the expected running time to O(NlogN) (ii) using approximation algorithms with O(NK) worst-case time, where K is the linear resolution of the image, and (iii) applying parallel techniques leading to logarithmic time in the worst-case. Though the growing rate of the time requirement of pre-selection is significantly slower than that of visibility, it is demonstrated that pre-selection has to deal with a significantly higher amount of data than visibility computations, as the average clipping volume is 1/27 of the volume of the model.
Digital Publishing
(Eurographics Association, 1997) Fellner, Dieter W.
This presentation covers the general topic of ‘Digital Publishing’ in the context of - the German MEDOC Project and - the German Strategic Digital Library Initiative V3D2 and, more specifically, - in the context of organizing EUROGRAPHICS’97 from the publication point of view. MEDOC is an effort by the German Computer Society (GI) to identify and to address the implications and challenges of digital libraries and electronic publishing on a wide scale. Starting in September 1995 the MEDOC project, partly funded by the German Ministry of Technology, has not only tried to implement a novel architecture for bringing relevant documents to the researcher’s desktop it has also raised the awareness on this important subject within the scientific community as well as within the group of publishers. The scientific counterpart to the application oriented MEDOC project is the strategic initiative V3D2 which is the (German) acronym for ‘Distributed Processing and Delivery of Digital Documents’. This initiative, funded by the German Research Foundation (DFG) over a period of six years and starting in 1997 provides a solid base for researchers from different disciplines (Computer Science, Library Sciences,Applied Sciences, . . . ) to tackle basic research and application issues focusing on ‘generalized electronic documents’. EUROGRAPHICS’97 is the first conference in its series to fully exploit the power of electronic documents and computer networks. This year, the submission of papers, the delivery of papers and attached multimedia material to the IPC members and to the reviewers as well as their online access, the feedback to the authors, and the delivery of the final documents (with the accompanying multimedia data) has been (almost) exclusively carried out electronically. This report briefly describes the architecture behind the work of the program committee from the first call for papers to the production of the printed proceedings and the CD-ROM holding the technical papers, STAR’s and tutorials. The experiences and lessons learned might be valuable to a general audience and not only to those organizing a scientific event in the near future.
Photo-Realistic Rendering - Recent Trends and Developments
(Eurographics Association, 1997) Slusallek, Philipp
Since the beginning of computer graphics, one of the primary goals has been to create convincingly realistic images of three-dimensional environments that would be impossible to distinguish from photographs of the real scene. The goal to create photo-realistic images has lead to the development of completely new software techniques for dealing with the inherent geometric and optical complexity of real world scenes. This report gives an overview of advanced algorithms for photo-realistic rendering and discusses recent trends and developments.
