Digital manipulation of landform is revolutionizing how our built environment is designed and constructed. On a technical level, three dimensional geometric modeling of topography has its origins at the interface of geographic information systems (GIS) and computer aided geometric modeling (CAD): the former with its representations of spatial attribute information with digital terrain in several representations (Triangulated Irregular Networks, contour lines, etc. ); the latter focusing primarily on the parameterization and combination of geometric primitives. The broadening of these two disciplines to embrace new surveying and navigation advances, e. g. global positioning systems (GPS), together with developments in engineering on the application side, are leading to powerful new suites of functionality. There has been a pronounced need for a forum where these traditionally separate parties can interact. These proceedings contain the technical papers selected and formally presented as part of the scientific program of the First International Symposium on Digital Earth Moving, 2001 (DEM 2001) held September 5 7, 2001 at the CIM Institute for Computing Science and Industrial Technologies of the University of Applied Science of Southern Switzerland (SUPSI iCIMSI) in Manno (Lugano), Switzerland. It is the first volume published on this explicit theme. Thirty six submissions were received, from fifteen countries, with thirteen select papers and posters presented in the official program and in this publication.

Computer Graphics through Key Mathematics introduces the mathematics that support computer graphics on a 'need to know' basis. Its approach means you don't have to do advanced mathematical manipulation in order to understand the capabilities, scope and limitations of the computer graphics systems that create impressive images. The book is written in a clear, easy-to-understand way and is aimed at all those who have missed out on an extended mathematical education but who are studying or working in areas where computer graphics or 3D design plays an vital part. All those who have no formal training but who want to understand the foundations of computer graphics systems should read this book, as should mathematicians who want to understand how their subject is used in computer image synthesis.

The wait for the year 2000 was marked by the fear of possible bugs that might have arisen at its beginning. One additional fear we had during this wait was whether - ganising this event would have generated a boon or another bug. The reasons for this fear originated in the awareness that the design of interactive systems is a fast moving area. The type of research work presented at this unique event has received limited support from funding agencies and industries making it more difficult to keep up with the rapid technological changes occurring in interaction technology. However, despite our fear, the workshop was successful because of the high-quality level of participation and discussion. Before discussing such results, let us step back and look at the evolution of DSV-IS (Design, Specification and Verification of Interactive Systems), an international wo- shop that has been organised every year since 1994. The first books that addressed this issue in a complete and thorough manner were the collection of contributions edited by Harrison and Thimbleby and the book written by Alan Dix, which focused on abstractions useful to highlight important concepts in the design of interactive systems. Since then, this area has attracted the interest of a wider number of research groups, and some workshops on related topics started to be organised. DSV-IS had its origins in this spreading and growing interest. The first workshop was held in a monastery located in the hills above Bocca di Magra (Italy).

This book constitutes the thoroughly refereed post-proceedings of the 6th International Workshop on Open Hypermedia Systems, OHS-6, and the 2nd International Workshop on Structural Computing, SC-2, held at the 11th ACM Conference on Hypertext and Hypermedia in San Antonio, Texas, USA in May/June 2000.
The 19 revised full papers presented were carefully reviewed and selected for inclusion in the book. All current issues on open hypertext systems and structural computing are addressed.

This book constitutes the thoroughly refereed post-workshop proceedings of the International Workshop on Vision Algorithms held in Corfu, Greece in September 1999 in conjunction with ICCV'99.

Also included are two invited contributions and two expert reviews as well as a panel discussion. The volume spans the whole range of algorithms for geometric vision. The authors and volume editors succeeded in providing added value beyond a mere collection of papers and made the volume a state-of-the-art survey of their field.

The AMDO 2000 workshop took place at the Universitat de les Illes Balears (UIB) on 7-9 September 2000, sponsored by the International Association for Pattern Recognition Technical Committee, the European Commission by - man Potential Program:High Level Scienti?c Conferences and the Mathematics andComputer Science DepartmentofUIB. Thesubject ofthe workshopwas- goingresearchinarticulatedmotiononthesequenceofimagesandsophisticated models for deformable objects. The goals of these areas are to understand and interpret object motion around complex objects that we can ?nd in sequences of images in the real world. These topics (geometry and physics of deformable models, motion analysis, articulated models and animation, visualization of - formable models, 3D recovery from motion, single or multiple human motion analysis and synthesis, applications of deformable models and motion analysis, etc. ) are interesting examples of how research can be used to solve more general problems. Another objective of this workshop was to relate ?elds using c- puter graphics, computer animation or applications in several disciplines c- bining synthetic and analytical images. In this regard it is of particular interest to encouragelinksbetweenresearchersinareasofcomputervisionandcomputer graphics who have common problems and frequently use similar techniques. The workshop included four sessions of presented papers and two tutorials. Invited speakers treating various aspects of the topics were: Y. Aloimonos from the Computer Vision Laboratory, Center for Automation Research, University of Maryland, USA, G.

The first International Workshop on Interactive Distributed Multimedia Systems and Telecommunication Services (IDMS) was organized by Prof. K. Rothermel and Prof. W. Effelsberg, and took place in Stuttgart in 1992. It had the form of a national forum for discussion on multimedia issues related to communications. The succeeding event was "attached" as a workshop to the German Computer Science Conference (GI Jahrestagung) in 1994 in Hamburg, organized by Prof. W. Lamersdorf. The chairs of the third IDMS, E. Moeller and B. Butscher, enhanced the event to become a very successful international meeting in Berlin in March 1996. This short overview on the first three IDMS events is taken from the preface of the IDMS'97 proceedings (published by Springer as Lecture Notes in Computer Science, Volume 1309), written by Ralf Steinmetz and Lars Wolf. Both, Ralf Steinmetz as general chair and Lars Wolf as program chair of IDMS'97, organized an excellent international IDMS in Darmstadt. Since 1998, IDMS has moved from Germany to other European cities to emphasize the international character it had gained in the previous years. IDMS'98 was organized in Oslo by Vera Goebel and Thomas Plagemann at UniK - Center for Technology at Kjeller, University of Oslo. Michel Diaz, Phillipe Owezarski, and Patrick Senac successfully organized the sixth IDMS event, again outside Germany. IDMS'99 took place in Toulouse at ENSICA. IDMS 2000 continued the tradition and was hosted in Enschede, the Netherlands."

Podcasting is the fast-growing media platform in the world, with currently 650,000 podcasts out there, in 100 languages, and offering over 20 million episodes. And we're only at the beginning. More and more podcasts appear every day, and more and more entrepreneurs, businesses, individuals, and distributors, like Spotify, are getting into this world. One person so many people turn to to help launch their podcasts is Eric Nuzum, a veteran of NPR and Audible who's had a hand in creating and launching over 130 podcasts, including some of the most successful out there like TED Radio Hour, Invisibilia, Where Should We Begin? with Esther Perel, The Butterfly Effect, and West Cork. And the reason is that Nuzum understands the essentials of what makes a podcast work, and knows how to help creators shepherd their vision from rough idea to finished product. Make Noise brings all the wisdom, advice, practical information, and big-picture thinking that any individual or business needs to make a successful podcast. He identifies core principles - create empathetically, i.e., think like the audience listens, and stay focused on what's unique to you and what you have to say. He helps readers come up with a "Ten Word Description" that will guide them throughout the creative process, and then gets into how-tos - how to develop character, story, voice; how to conduct an effective interview; how to be mindful of the limitations of audio (be more like Hemingway than Faulkner). Here are the rules of storytelling, advice on how to test-drive an idea (make six individual lunch dates, talk it over with each, and by the end see how you've refined your thinking), and, when it's all ready, how to develop your audience.

The papers in this volume were selected for presentation at the 6th Annual International Computing and Combinatorics Conference (COCOON2000), in Sydney, Australia from July 26 - 28, 2000. The topics cover many areas in t- oretical computer science and combinatorial optimization. There were 81 high quality papers submitted to COCOON2000. Each paper was reviewed by at least three program committee members, and the 44 papers were selected. It is expected that most of them will appear in a more complete form in scientic journals. In addition to the selected papers, the volume also contains the papers from two invited keynote speeches by Christos Papad- itriou and Richard Brent. This year the Hao Wang Award was given to honor the paper judged by the programcommittee to have the greatest merit. The recipient is \Approximating Uniform TriangularMeshes in Polygons"byFranz Aurenhammer, NaokiKatoh, Hiromichi Kojima, Makoto Ohsaki, and Yinfeng Xu. The rst Best Young - searcher paper award was given to William Duckworth for his paper \Maximum Induced Matchings of Random Cubic Graphs." We wish to thank all who have made this meeting possible: the authors for submitting papers, the program committee members and the external referees, sponsors, the local organizers, ACM SIGACT for handling electronic subm- sions, Springer-Verlagfor their support, and Debbie Hatherellfor her assistance.

Ten years ago, the inaugural European Conference on Computer Vision was held in Antibes, France. Since then, ECCV has been held biennially under the auspices of the European Vision Society at venues around Europe. This year, the privilege of organizing ECCV 2000 falls to Ireland and it is a signal honour for us to host what has become one of the most important events in the calendar of the computer vision community. ECCV is a single-track conference comprising the highest quality, previously unpublished, contributed papers on new and original research in computer vision. This year, 266 papers were submitted and, following a rigorous double-blind review process, with each paper being reviewed by three referees, 116 papers were selected by the Programme Committee for presentation at the conference. The venue for ECCV 2000 is the University of Dublin, Trinity College. - unded in 1592, it is Ireland's oldest university and has a proud tradition of scholarship in the Arts, Humanities, and Sciences, alike. The Trinity campus, set in the heart of Dublin, is an oasis of tranquility and its beautiful squares, elegant buildings, and tree-lined playing- elds provide the perfect setting for any conference.

Analysing Musical Multimedia is the first study to produce a general theory of how different media - music, words, moving picture, and dance - work together to create multimedia. Beginning with a study of how meaning is mediated in television commercials, Nicholas Cook concludes with in-depth readings of Fantasia, Madonna's video Material Girl, and Armide (Godard's sequence from the collaborative film Aria).

Min Chen, Arie E. Kaufman and Roni Yage/ Volume graphics is concerned with graphics scenes defined in volume data types, where a model is specified by a mass of points instead of a collection of surfaces. The underlying mathematical definition of such a model is a set of scalar fields, which define the geometrical and physical properties of every point in three dimensional space. As true 3D representations, volume data types possess more descriptive power than surface data types, and are morphologically closer to many high-level modelling schemes in traditional surface graphics such as parametric surfaces, implicit surfaces and volume sweeping. The past decade has witnessed significant advances in volume visualisation, driven mainly by applications such as medical imaging and scientific computation. The work in this field has produced a number of volume rendering methods that enable 3D information in a volumetric dataset to be selectively rendered into 2D images. With modern computer hardware, such a process can easily be performed on an ordinary workstation. More importantly, volume-based rendering offers a consistent solution to the primary deficiencies of the traditional surface-based rendering, which include its inability to encapsulate the internal description of a model, and the difficulties in rendering amorphous phenomena. The emergence of volume-based techniques has not only broadened the extent of graphics applications, but also brought computer graphics closer to other scientific and engineering disciplines, including image processing, computer vision, finite element analysis and rapid prototyping.
