    The Norwich Virtual City Project
    (Eurographics Association, 1999) Arnold, D. B.; Day, A. M.
    This paper describes the early work on implementing a visitor attraction based on the heritage of the Norwich area. The project has been in planning for about three years, but has only just been funded and is due to open in 2001. The paper reviews the background to the project and the city, and considers the expected benefits of the venture. The range of data sources are then reviewed and areas are highlighted where computer science research needs to progress to maximise benefits. The paper then reviews progress to date on the project.

    Las Meninas: Narrative Illusions in Virtual Reality
    (Eurographics Association, 1999) Bizri, Hisham M.
    Las Meninas is a virtual reality artwork based on the painting of the same name by the Spanish painter Diego Velazquez. Created for the CAVE-Automatic Virtual Environment, Las Meninas is fused with narrative illusions as the audience explores the enigmas inherant in the painting by exploring the physical and mental space of the painting.

    Gaseous Volume Visualization Using Particle Maps
    (Eurographics Association, 1999) Adabala, Neeharika; Manohar, Swami
    This paper presents a new method of rendering gaseous volumes using particle maps which store the particles that model the gaseous volume. The particle maps enable quick estimation of densities within a gaseous volume during rendering, analogous to how photon maps enable estimation of radiance during ray tracing. Particle based approaches to model gases are inherently simple and facilitate easy inclusion of physical correctness, but do not generally give realistic images. The alternate of texture based approaches give realistic images but have limited scope for inclusion of physical correctness. We combine these two approaches to give a method that (i) has flexibility to model any gaseous geometry, (ii) offers high scope for incorporation of physical correctness, (iii) does not possess arcane control parameters and (iv) results in realistic images.

    Virtual Reality and Cultural Heritage Examples: the Mysterious City Fresco, the Domus Aurea
    (Eurographics Association, 1999) Cuomo, Massimo; Funto, Fabrizio; Levner, Geoff
    Cultural heritage can benefit greatly from the use of virtual reality. Among the demands of cultural heritage that this technology can help to satisfy are the following: Giving laymen the opportunity to appreciate works from the past of which only fragments remain, or which contain cultural references that have been lost over time. Providing researchers with powerful tools. Ensuring the preservation of cultural heritage over risky restoring and degradation due to excessive number of visitor. Making virtual replicas that can be transported without risk to the original, increasing enormously the number of potential visitors. Two examples are presented: The Mysterious City Fresco and The Domus Aurea.

    Baroque Dance Animation with Virtual Dancers
    (Eurographics Association, 1999) Bertolo, Maresa; Maninetti, Paolo; Marini, Daniele
    Our approach to computer simulation of the human movement is based on a high level description of the grammar of the movement and on the combination of basic movements acquired using motion capture systems. The combinatory techniques inspired by the ancient notation system of the Baroque Dance can lead to achieve complex tasks like synchronisation with the music tempo and rhythm in a simple way. The first phase of our project was the study of the human morphology and possible movements in the Baroque Dance, then we built an anthropomorphic 3D model which articulated structure makes it able to dance. Then we studied the major Baroque Dances, to identify their syntactic structure suitable for a hierarchical decomposition of a complete choreography. Third, we encoded the elementary movements by using a motion capture system with a professional human dancer, building two libraries of simple and complex movements, to be used for the control of the motion of the 3D articulated figure in two dinstict cases: for real-time generated dances and for rendering-based generated dances. Synchronisation with the music tempo and rhythm has also been solved, thanks to the rule that each musical measure corresponds to a complex step, or a word in our metaphor.We implemented two kind of interactive web tools to be used by the choreographer in order to define a choreography for the virtual dancer. The result is an easy to use animation system, settled as an educational application.

    Rapid Urban Modelling
    (Eurographics Association, 1999) Cooper, J. W.; Arnold, D. B.; Day, A. M.
    We describe a system that allows the rapid creation of virtual urban models. We describe how this system can extract 3D model information from Ordnance Survey maps by using a rule-based modelling approach and a parameterised description for common buildings. We also give ideas about how this system could be extended to add detail to models generated from aerial photographs and to include historical events within the model. Finally we show how the models can support changes in level of detail and compression.

    Filtering mechanisms for the visualization of non-geometrical and geometrical data
    (Eurographics Association, 1999) Carmo, Maria Beatriz; Cunha, Joao Duarte; Claudio, Ana Paula
    The paper describes a fundamental feature in a prototype for the visualization of both geometrical and non-geometrical data: filtering mechanisms. The information class is a basic concept of this prototype. Each class combines a set of attributes associated to the same spatial reference with a list of graphical representations. Information filtering can be accomplished using the following mechanisms: limiting the variation domain of information class attributes, suppressing the visualization of one or more information classes, using the degree of interest function, selecting specific graphical representations accordingly both to the scale of representation and to the degree of interest function, displaying the data by levels of interest.

    Interference Detection in Architectural Databases
    (Eurographics Association, 1999) Dias, José Miguel Salles; Gamito, Manuel Noronha; Silva, Jorge; Fonseca, José; Vilar, Miguel; Luo, Yuhua
    In this paper we address the problem of geometric interference in architectural databases, that arises when different architecture and structural engineering teams integrate their designs into a common 3D scene. By analysing in detail the current work practices, we have modelled a design verification matrix for interference cheking, between architectural (wall, window and door openning, etc) and structural design elements (column, beam, roof slab, etc). In our novel algorithm, we’ve implemented a Binary Space Partitioning (BSP) scheme for all the scene elements, along with several boolean operators that apply to the BSP tree. Every interference can be expressed as a boolean equation that must hold true. Each pair of architectural and structural elements, from the verification matrix, is substituted into the relevant equations and, if a false result is obtained, an inconsistency is visualy signalled and can be discussed at a distance, using our own multi-user 3D virtual environment.

    Virtual Environments as Multimedia Contents Integrators
    (Eurographics Association, 1999) Biancardi, A.; Moccia, V.
    Broadband networks, the digital nature of current multimedia contents and the increasing crossover between Internet and television are marking the beginning of a cultural revolution. As a tool for the integration of multiple media technologies in three-dimensional virtual spaces, Siru is the ideal environment for the convergence of different sources of information in a unified context. Streaming video and audio, 3D objects, and hypertexts can all be integrated with Siru to build homogeneous compelling digital experiences

    Exploiting Pompei Cultural Heritage: The Plinius Project
    (Eurographics Association, 1999) Antonicelli, Angela; Sciscio, Giovanni; Rosicarelli, Renato; Ausiello, Giorgio; Catarci, Tiziana; Ferrarini, Massimo
    Enlarging and improving the fruition of national cultural heritage is becoming a crucial goal for many nations, obviously including Italy, which owns the larger set of ancient findings of the world. The Plinius project1 is part of this goal. In particular, it concentrates on the archaeological heritage of the Pompei site with a twofold objective. On one side, it aims at allowing different classes of users to enjoy and exploit the Pompei cultural heritage, by providing them with a suite of personalised tools, whose features address the different needs of the various user classes, ranging from the archaeologist to the casual visitor. On the other one, it intends to retrieve and reengineer the outcoming of a previous twenty-year old software projects, which stored and catalogued a huge amount of information about Pompei findings into a legacy system, based on an obsolete hardware architecture. In this paper we introduce the Plinius project by briefly describing its context of use, the user classes, the system architecture and functionalities.

    A VR based safety training in a petroleum refinery
    (Eurographics Association, 1999) Haller, Michael; Holm, Roland; Volkert, Jens; Wagner, Roland
    We present the prototype omVR, which is a Virtual Reality based safety training system in a petroleum refinery. It provides an advanced technique for personnel safety training and allows users to navigate through the training setup and interact with parts of the refinery. By using a head mounted display a high degree of immersion is achieved. omVR is the implementation of a training scenario, which is too dangerous, difficult, or expensive to be performed in real life. In our system the trainer has the possibility to control the scenario from a remote trainer module which communicates with the VR simulation program.

    Monitoring of the visual arts degrade by means of the active vision system “3EYES”
    (Eurographics Association, 1999) Cojoc, D.; Grattoni, P.; Nerino, R.; Pettiti, G.
    Monitoring of some physical characteristics (colour, geometry, size of fissures, ...) of object surfaces is of utmost importance in the field of conservation and restoration of work of arts. In order to get effective results a very high repeatability in the localization of the test points is required. At present, repositioning is a tricky task and is performed by means of manual empirical procedures which can be time consuming and expensive. In this short paper an application of the 3EYES active vision system to the automation of the monitoring is presented. An application of the system to object monitoring in laboratory environment is described.

    Books and Devices from the Old -Their Renaissance in Computer Graphics
    (Eurographics Association, 1999) Eberhardt, Bernd; Gürcay, Hasmet; Hanisch, Frank; Hüttner, Tobias; Licht, Oliver; Nill, Benjamin
    In the following we present three of our institute’s activities concerning cultural heritage. First we present a reconstruction of the Antikythera Mechanism, which is the world’s oldest calculator of astronomical purpose. The implementation extensively uses engines and sensors from the OpenInventor Graphics Library. This is a particularly interesting example of a delicate object which cannot be exhibited (without the use of a virtual Computer Graphics model) since it is too valuable and delicate. Secondly we illustrate the use of Computer Graphics to make valuable medieval books available to the public. A new texture mapping approach, allows the bilinear interpolation of texture coordinates on an arbitrary triangle mesh. This approach uses projective texture mapping and can therefore utilize the hardware of modern graphic workstations. Lastly we present an application of modern 3D Computer Graphics in the field of reconstructing ancient scientific instruments. The first-four-species calculator of Wilhelm Schickard is made accessible to the public in the World Wide Web using Java3D. All three examples illustrate the use of latest technology to model ancient books or devices.

    There has been great interest in expressive visualization over the last few years. This kind of visualization is used in 2D animation, illustration, and schematic drawing. The flat shading and shape lines, which we call external and internal sketches, are all visual charasteristics of this type of visualization. We present an algorithm for obtaining the sketches from a polygonal model. The algorithm is based on the concept of virtual lights, which allows us to control the visualization of internal sketches in a flexible way.

    3D virtual facial reconstruction and visualization of ancient Egyptian mummies using spiral CT data
    (Eurographics Association, 1999) Attardi, Giuseppe; Betro, Marilina; Forte, Maurizio; Gori, Roberto; Guidazzoli, Antonella; Imboden, Silvano; Mallegni, Francesco
    The problem of rebuilding a face from human remains has been, until now, especially relevant in the ambit of forensic sciences, where it is obviously oriented toward the identification of otherwise unrecognizable corpses; but its potential interest to archaeologists and anthropologists is not negligible. We present here the preliminary results of a joint research among the University of Pisa, the Visualisation Laboratory of CINECA and the CNR-ITABC (Institute of Technologies Applied to Cultural Heritage, National Research Council, Rome) whose aim is reconstructing, through Spiral Computed Tomography data and virtual modelling techniques (in our case with VTK software), 3-D models of the possible physiognomy of ancient egyptian mummies. This work is carried out through a multidisciplinary approach, involving different competences: image processing, anthropology, egyptology, computing archaeology. Main project tasks are: 1. anthropological and egyptological analysis of the head; 2. spiral CT of the head; 3. reconstruction of a 3-D model of the skull generated from CT data processing; 4. reconstruction of soft tissues; 5. application of textures fitting the somatic features.

    Fast Distance Field Interpolation for Reconstruction of Surfaces from Contours
    (Eurographics Association, 1999) Klein, Reinhard; Schilling, Andreas
    One simple and robust way to get a reconstruction of surfaces from a given contour stack dealing well with branching and other problems which are generally difficult to solve is based on the well known MC-algorithm. To overcome the staircase artefacts produced by the MC-algorithm Jones et. al. 3 proposed to use a distance field interpolation between the slices and to run the MC-algorithm on this distance field. The main problem of this approach is the distance field computation as it is very time consuming especially if high resolution grids (e.g. 10241024 are used. Therefore, in the original algorithm the resolution of the chosen grid is much less than the resolution of the given contour sacrificing accuracy of the resulting surface. Especially in medical applications this is not accepted by the doctors. In this paper we introduce a new method for the computation of the discrete distance field, which is a breaktrough in terms of speed and accuracy. This new method allows us to reconstruct surfaces from contour stacks with guaranteed accuracy in reasonable time. Several examples show the power of this approach.

    The Danteum was a building designed for Rome in 1938 by two eminent Italian architects, Giuseppe Terragni and Pietro Lingeri. Due to the defeat of their client, Mussolini, in WW II, the project was never realized and became one of the best known unbuilt modern projects. Through the use of advanced computer graphics technology, an attempt has been made to simulate a walk-through experience of light and materials inside this unbuilt monument. This animated representation revealed two of the important spatial characters embedded in the design of this building: a constant oscillation of dark and light as well as that of closed and open.

    A Global Routing Mechanism for Modular VRML-Worlds
    (Eurographics Association, 1999) Mader, S.
    With the increasing complexity of virtual worlds VRML97 reveals its lack of native support for logical modularization of these worlds. Though the inherent mechanisms as PROTO-typing and Inlining allow us to partition our worlds into several files, the restriction to file-limited namespaces makes an event-routing for complex interactions between different modules a rather difficult task. In this paper we present an easy-to-use method for event-based communication across modular VRML scenes. Based on VRML´s event model, this solution goes conform with the VRML97 standard ISO/IEC 14772-1:19971 . In order to show its ability to support the implementation of highly interactive and complex VRML-worlds we demonstrate its application in a current project from the fields of virtual heritage.

    Wavelet Projections for Volume Rendering
    (Eurographics Association, 1999) Horbelt, Stefan; Unser, Michael; Vetterli, Martin
    We extended Gross’s 3 method of volume wavelet rendering by computing splats via an orthogonal projection operator. The method decomposes the volume data into a wavelet pyramid representation in the spline domain. The splats of the basis functions are approximated on a multiresolution grid. Using least-squares approximation ensures the smallest possible error for a given sampling step size. The approximation error on the grid is derived as a function of the sampling step h. The choice of the appropriate wavelet space and spatial resolution at each step produces the smallest possible filters. Our approach reduces the number of computations and allows full control of the image quality.

    WebTalk: a 3D collaborative environment to access the Web
    (Eurographics Association, 1999) Paolini, P.; Barbieri, T.; Loiudice, P.; Alonzo, F.; Arru, M.; Zanti, M.; Gaia, G.
    The notion of cooperative visit and interaction within a web site, both at 2D and 3D level, could add decisive motivation to pursue exploitation of the third dimension in networked environments. A prototype developed at the HOC laboratory in Politecnico of Milan, WEBTALK, allows development of custom 3D environments in which actions and situations can be shared throughout a network. The current prototype makes use of standard web-based Internet/Intranet technology: it is composed of a VRML (Virtual Reality Modeling Language) graphical engine and a Java-based TCP/IP (the Internet Protocol) communication layer. The technique has proven itself successful and has given rise to several interesting applications, such as the creation of Virtual 3D Museum Spaces at the National Science Museum (www.museoscienza.org), in which visitors can visit the museum interacting with the exhibits themselves and sharing their experiences with other visitors - even joining a guided tour with the virtual museum guide. A new prototype will make use of a completely Java-based environment, using Sun’s Java 2 and Java 3D. The new WEBTALK will stress even further the issues of third party external authoring of virtual worlds and of cooperation patterns within the shared environments, with a distinction between shared object geometries, shared object behaviors, shared object data (stored in an on-line DBMS), and cooperation metaphors within the virtual world. Linking to 2D-based web sites resources will lead cooperation patterns to be extended also to regular web-space.

    Accelerated Artificial Landscape Visualisation

    We describe the design and implementation of four stages in an artificial landscape visualisation program. We begin by outlining a very simple but quick method of generating structurally realistic landscapes. We describe how the terrain can be stored in a multiresolution Binary Space Partitioning (MRBSP) tree such that each level holds a complete representation of the terrain at increasing reso- lution. A level of detail (LOD) technique is then illustrated which preserves the visually apparent size of triangles (after projection) so that the number rendered is reduced while preserving the aesthetic quality. Finally, we show how visibility calculations can be preprocessed and used to achieve output sensitivity by limiting the observer to ground based motion.

    Psycho-social Happenings in Mediated Environments

    One of the virtues of our changing times is that new media has challenged us to rethink and re-examine our basic presumptions about reality and the reality that is virtually perceived. From the perspective of an elec - tronic-media artist, I present a body of work (CASE STUDIES) of performative-like installations comprised of 3-D structures integrating video imagery with the reality of the physical, psychological, virtual, and social worlds. These structures are instigators for enticing “social happenings” whereby participants and viewers become subjects from an observational perspective, providing a simulated clinical “case study.” Raising issues of belief and perceptions of trust in the constructs of mediated environments, the demarcation between virtual risk and real risk (virtual reality and reality) breaks down.

    A Rapid Clustering Algorithm for Efficient Rendering
    (Eurographics Association, 1999) Müller, Gordon; Schäfer, Stephan; Fellner, Dieter W.
    Hierarchical radiosity using object clusters greatly improves rendering times and reduces memory consumption of radiosity computations. The key feature of the algorithm is using a hierarchy of object clusters to approximate the energy exchange between surfaces. The cluster hierarchy used for this purpose however, must accurately reflect the actual scene geometry to justify this approach. Bad clusters easily lead to rendering artifacts. Inspired by the results of our hierarchical bounding volume optimization for ray tracing, we applied the same scheme to a clustering algorithm for hierarchical radiosity. Using an object-oriented framework, the extension of the implementation was straight forward and seems to be promising. Due to the good performance of our hierarchy regarding ray tracing, the same data structure could successfully be used for two things: visibility checks based on ray casting and energy exchange for the radiosity computation. In this short paper, first results regarding our new clustering scheme will be presented. The properties of the underlying bounding volume optimization give reason for interesting applications enhancing various rendering techniques. Some of these new ideas will be discussed here.

    With the advent of whole body, 3D electro-optical scanners, a new range of applications are emerging that exploit the availability of personalised, realistic human models. However, realistic rendering of such models usually entails a large number of polygons which can be unacceptable in many applications. We present a framework that exploits the approximate cylindrical and spherical symmetry of human body parts to create light-weight representations that retain the overall dimension of body parts, even at very low polygon counts.

Experimental results demonstrate that the method performs better than the method using uniform B-splines.

    A Pyramidal Hemisphere Subdivision Method for Monte Carlo Radiosity
    (Eurographics Association, 1999) Jolivet, Vincent; Plemenos, Dimitri; Sbert, Mateu
    In this paper we present a new method to improve Monte Carlo radiosity by sending more rays towards selected directions. More precisely, we determine regions of the scene where the distribution of the power must be done more accurately. The number of rays sent in a direction is a function of the number of patches contained in a region, a region being a pyramid defined by the centre of the shooting patch and a spherical triangle on the surface of a hemisphere surrounding the patch. Thus, the rays shot from a patch do not have all the same power. The new method allows us not only to obtain fine details much sooner and with lower cost, but also the overall efficiency is considerably increased.

    Better Pasting Via Quasi-Interpolation
    (Eurographics Association, 1999) Mann, Stephen; Conrad, Blair
    In this poster, we show our latest work on surface pasting, a hierarchical modeling technique. In surface pasting, we attach a feature surface to a base surface using an approximation technique. While we can use knot insertion on the feature to get the approximation to any level of tolerance, knot insertion increases the size of the representation of the feature. The work we present in this poster shows how we use quasi-interpolation to improve the approximation, allowing us to use smaller representations of our features.

    The Aurora
    (Eurographics Association, 1999) Sugano, Yoshinori; Masuda, Eiko
    As you peek into Japans history of fine arts, a traditional way of expressing pictures can be found. It all started from printing scrolls way back in the 12th century and now turned into a medium as known as manga. Today Japan is the world largest producing country of manga and its animation can be seen almost anywhere in the world. These manga-loving people are now beginning to create computer graphic animation. All though the method have changed, the importance on the theme depicted therein haven’t changed. Until now, a big topic of CG animation was to create images to look just like the "real". However from the advance on technology, CG animation came to a point where creating the picture to feel "real" is becoming the big subject. Symbolizing the image is thought as a way to express the "real" picture. "The Aurora" is challenging to reach a new genre of an image, different of those "photoreal", by symbolizing the act and giving more meaning to the animation.

    Emotion-based, Multi-person Interactive Theatre - Romeo and Juliet in Hades
    (Eurographics Association, 1999) Tosa, Naoko; Nakatsu, Ryohei
    Now a days many Interactive Theater research is appeared[1][2][3][4]. We have developed an emotion- based interactive theater system. The characteristic is the use of Interactive Computer Graphics technology and the generation of three-dimensional imagery to create autonomous actors and a cyberspace in which all participants obtain a feeling of immersion. We have developed a system that includes multi person participation, emotion recognition and gesture recognition through. In this system, participants can feel they are actually contributing to the development of the story in cyberspace. This is done a system that shows avatars on thescreen as the alter ego of the participants. We have also produced an interactive story based on this system.

    Animating Brachiation
    (Eurographics Association, 1999) Zhang, Zheng; Wong, Kok Cheong
    This paper presents a physically-based animation system for generating realistic motion of primate brachiation. One of the main aims of this system is to facilitate the process of generating brachiation sequences with appropriate automaticity and also provide the animator with adequate controllability. A hybrid system based on an integration of three control modules of different levels. The low-level control module, namely forward dynamics interactive module can be employed to rapidly manipulate the torque values at specific joints of a simplied primate figure. Both the mid-level and high-level control modules are designated to automate the process of generating the basic global brachiation movements of the primate figure. The performance of the system is evaluated by measuring the animation results qualitatively and quantitatively. Experimental results have demonstrated the effectiveness and robustness of the paradigm by generating animated sequences of realistic brachiating motion

    Edinburgh: 200 years of heritage through image-based virtual environments
    (Eurographics Association, 1999) Wright, Mark W.; Watson, Gordon; Dunlop, Gair; Middleton, Roy
    Heritage is an important application of virtual environments. The key role of virtual environments in this sector is to provide a spatial context for historical records, artifacts and places. This spatial context makes the material more readily understandable by the public and provides a useful framework for teaching and research. Furthermore, the delivery of such material over the Internet turns heritage itself into a virtual commodity with all the associated economic advantages. Freed from physical and geographical constraints the material can be made available to a much wider audience at remote locations.
