Introduction to Multimedia, Hyper-Media and Virtual Reality

Multimedia Systems support the physical and logical coexistence and interac­tive use of heterogeneous media classes such as Print, Audio and Video in specific application environments. By definition, the media class Print includes static media types such as text, graphics, facsimile and natural image; the media class Audio includes dynamic media types such as natural and synthetic sound, speech, and music; and finally, the media class Video includes dynamic media types such as natu­ral and synthetic image sequences.
Hyper-Media and Virtual Reality applica­tions are based on multimedia systems.
Hyper-Media extends the media-ori­ented features of multimedia systems by the concept of hyperlinks, e.g. logi­cal structures that provide the means for organizing media objects in a flexi­ble, logically coherent, network-oriented and non-sequential way.
Virtual Reality extends the interaction-oriented features of multimedia by the concept of cyberspace, e.g. modeling objects and their behavior in virtual environ­ments, integrating position-tracked man-machine interaction devices and per­forming numerically intensive computations to guarantee real-time naviga­tion.
Multimedia Systems as well as Hyper-Media and Virtual Reality applications rely heavily on available Information and Communication Technologies. As the performance of these resources continuously improve and extend, media research and development activities never come to a halt either.

The MultiMedia Laboratory
Head: Peter Stucki, Prof. Dr. sc. techn. ETH, DIC

The MultiMedia Laboratory (MML) was founded in 1986. Its original objective was to do research and advanced development work in Multimedia System-, Hyper-Media- and Virtual Reality-design, advanced application prototyping and media management. Also of interest was the exploration of digital media to serve interests and needs at the University of Zurich, in particular those arising in the humanities, natu­ral sciences, medical commu­nities and the Faculty of Economics, Business Administration and Information Technology as well as to the interdisciplinary field of computer supported education (e-Learning).
Soon after is foundation, the MML became comfortably equipped with advanced state-of-the art equipment e.g. a Reduced Instruction Set Computer (RISC) prototype for 2D image processing and number crunching, several Silicon Graphics Super Workstations for 3D graphics, a digital Video Disks to record and replay digital videos and synthetic movies, a Stereo-lithographic 3D printing facility, etc.
Given this unique and comfortable infrastructure, the ongoing research and application development projects soon became predominately of interdisciplinary nature. It served many research­ers and students as a platform for problem oriented studies and work.
Besides publishing the research findings in many renowned journals such as IEEE Transactions, ACM publications, Nature, etc., many interdisciplinary projects were carried out with a number of academic, institutional and industrial partners.
After 18 years of service at the MultiMedia Laboratory of the Department of Computer Science and four years as Dean of the Faculty of Economics, Business Administration and Information Technology, Prof. Stucki took retirement from the University of Zurich in fall 2003.
Many of the projects came to a natural end, some others continued on a reduced personnel base. The University management had decided to split the chair of Prof. Stucki in a position in Computational Sciences at the Faculty of Mathematics and Natural Sciences and a position in Multimedia and Scientific Visualization at the Faculty of Economics, Business Administration and Information Technology.

Extending Experimental Reduced Instruction Set Computing (RISC) Hardware for Fast Execution of Selected Image and Signal Processing Algorithms
Fürst, M. Dürst (1985-1987)

IBM Switzerland donated to the MML a Reduced Instruction Set Processor (RISC) hardware prototype developed at the IBM Spain Madrid Scientific Center. This system came without a usable Operating System (OS) and hardware components that could be re-assembled and/or extended. H. Fürst responsible for the RISC hardware, transferred this system from Madrid to Zurich, M. Dürst took the challenge of extending the very limited RISC instruction-set to include additional and specific Signal Processing Instructions and so upgrading the hardware prototype to a Reduced Instruction Set Signal Processor (RISSP).

Face- and Gesture-Recognition
H. Ghezal, M. Bichsel, Th. Fromherz (1986-1997)

The automatic identification of objects, persons, facial expressions and ges­tures is a challenging research topic. The objective of this project was the conception and development of the necessary theories, algorithms and implementations for human face and gesture recognition. Several approaches have been investigated. These activities started out by doing face recognition research using artificial neural nets (Ghezal) then continued taking conventional recognition work to more advanced 3D model-based, shape-from-x approach for image capture and recognition in real-time (Bichsel, Fromherz). They also included techniques based on motion anal­ysis, matched filters, and 3D model-based procedures. As part of the phys­ically based recognition approach, new concepts and algorithms for shape from multiple views and multiple cues have being developed, leading to promising results for shape-enhanced face recognition.

Algorithmic Comparison between Square- and Hexagonal-Based Grids
C. A. Wüthrich (1987-1991)

Image digitalization, that is the conversion of natural pictures into a discrete set of points, has been one of earliest subject of study for computer scientists involved in digital image and graphics research. This project did clarify the open questions whether square-based or hexagonal-based grids perform better and if yes, how to find valid scientific criteria to support such expectations. To do so, models of human vision had to be understood and integrated into the technical evaluation.

Understanding Photorealistic Image Synthesis
U. Meyer (1987-1991)

Advances in computing technologies allow the numerical calculation of increasingly sophisticated photorealistic rendering algorithms and procedures. By doing so, realistic light sources have to be included into the computational schemes and concepts of hard- and soft- shadows understood. This fact poses a multitude of new problems that need to be investigated in a systematic way. Also the understanding of computational requirements and efficiency play a significant role as well. Prototyping new and sophisticated synthetic image rendering software components was part of this project.

Digital Film Analysis
M. Hafner (1987-1994)

Motion pictures recorded on chemical film represent an important cultural heritage. These images, however, are often badly damaged. On high-end multimedia system platforms, high resolution moving images can be scanned, digi­tized, processed and reproduced. Digital restoration of old films therefore becomes feasible. This study developed new algorithms for model based robust motion estimation and motion compensated image sequence filtering which enable automated restoration of heavily damaged image sequences. The basic objective was to understand the requirements for digitally removing image artifacts typical for damaged motion pictures film masters.

The objective of this project was to conceive and implement an interactive and  generic image processing / image understanding software environment for the analysis and classification of micrographs that represent healthy and damaged retina cells. In a later phase of this work, a 3D modeling and rendering toolkit was developed that allows the interactive generation of 3D retina cell reference models for visual comparison.

Blackboard-Based Text Recognition Using Contextual Knowledge Sources
A. Garzotto, R. Sennhauser (1991-1995)

Advances in the development of text recognition systems for printed text led to a signi­ficant improvement of character recognition rates. In spite of these improvements, the recognition result of state-of-the-art text recogni­tion sys­tems is still not perfect. In this project, two different approaches are simulta­neously investigated to improve the recognition accuracy, namely the use of a blackboard-based text recognition framework and the applica­tion of various contextual knowledge sources. The text recognition frame­work integrates several competing character recognition and segmentation knowledge sources which all attempt to solve the same sub-problem. A set of contextual know­ledge sources cooperates seamlessly with all other knowledge sources and substantially improves the initial recognition result.

Lossless Data Compression Using Arithmetic Coding
K. Ohnesorge (1991-1995)

The majority of image data compression procedures view the data stream as a one-dimensional finite context Markov chain. In order to model digital images, their two-dimensional structure should be reflected in related data structures and order of processing. The objective of this project is to investi­gate two-dimensional and hierarchically higher order Markov chains and to implement corresponding probabilistic models for lossless image compression based on the technique of arithmetic coding. The results obtained show better compression performance than Ziv-Lempel and lossless JPEG procedures.

Planning of Cranio-Maxillo-Facial Surgery and Fabrication of Protheses: CT-Artifacts Suppression and Rapid Prototyping Using the Technology of Stereolithography (3D Copying)
M. Path, Chr. Zollikofer (1995-2000)

The main objective of this project is to reduce artifacts in pre-surgical cranio-maxillo-facial CT-scans so that proper 3D-models can be built with the stereolithograph.  Due to the low power beams permitted in skull CT-scanning, metallic implants (such as fillings or orthodontic devices) cause massive artifacts in resultant CT-images. If this data is to be used for surgery planning, the artifacts must be eliminated.  Normally this is done by the time-consuming process of manually editing each image. This project develops methods which reduce the artifacts in the CT-images automatically. For this purpose a CT simulation environment was implemented with the help of new programming concepts such as visual programming and others (EUREKA Project).

2. Computer Image Synthesis (2D, 3D and 4D Computer Graphics)

Generic Virtual Reality Based Information System Framework
K. Szabó (1987-1993)
Virtual Reality (VR) environments offer a new kind of human-computer- as well as human-human-interaction. The user of a VR system can immerse into a computer-generated, multi-sensory, intuitively operable virtual experience space and interact with virtual objects in real-time.
By the help of a new methodology for systematic analysis and evaluation of VR systems, the system architecture, design rationales and user interface metaphors of three VR application prototypes have been elaborated and implemented. These are accompanied by system performance and usability experiments. The first prototype, a VR based Geographic Information System, implements sophisticated methods and techniques for efficient data management in real-time by applying a client-server architecture. They allow the dynamic loading of virtual environment data at runtime and optimize load strategies for increased runtime performance. User interface aspects of VR applications are discussed with the help of two other prototypes, a cockpit based immersive driving simulator and a VR based holiday house exploration environment. Furthermore, a new VR software architecture is proposed to improve the integration of additional peripheral devices into an existing VR system environment and to enable the development of software components that execute in parallel.
The close relationship of the three application prototypes to the field of tourism allows one to apply the findings to the design of architecture models and user interface metaphors for VR based tourist information systems. Recent works focus on the application of VR technology within the financial business sector including implementations of VR based Financial Information Systems (ViRFIS) for Internet and Intranet application domains.

Advanced Graphical Editors
M. Dürst, R. Schleich (1992-1995)
This project proposes a new approach to the visualisation of hidden information in the form of trees and graphs by means of so-called structure browsers. They offer a multitude of auxiliary information that can currently be manipulated directly in order to improve efficiency. All concepts have been imple­mented and experimentally verified in an object-oriented prototype. This work enhances the functionality of current graphical editors by introducing concepts for visualization of hidden structural information for better object understanding and manipulation. In traditional design systems, most of the relations between design objects remain hidden.

3D Text Processing and Font Design / Internationalization of Interface Software
M. Dürst, W. Harris (1994-1997)
Admidst the wealth of multimedia data types, the significance of text is frequently underestimated, but high quality text in dynamic multimedia documents and the globalization of computing pose new research chal­lenges and opportunities. New models and approaches are being investi­gated in the following areas: multilingual text integration based on applica­tion frameworks; structured font design for large charac­ter sets; handling of multi-script text in Internet application layer protocols.
The work also requires the understanding and the implication of UNICODE, multi-lingual text integration, font design structures and tools for large character sets (Japanese, Korean, Arab, etc.). This work is currently extended to include the representation and mani­pulation of 3D Text in virtual space environments.

High Quality Text in 3D Environments
W. Harris, M. Duerst (1995-2001)
Current research in 3D systems and environments has produced high-quality results for traditional graphics. However, non-decorative text, serving as a substantive information-transfer medium, remains non-integrated. Through the integration of traditional 2D raster technologies and the innovation of novel 3D rendering algorithms, this project aims to provide high-quality text representations in 3D fields of application such as user interface design, VR, and scientific visualization.
The MML’s Multimedia Editor Toolkit (MET++) application framework has been extended to provide 3D visualization of 2D applications. A projection port maps 2D drawing primitives to their 3D equivalents. The last approach to rendering text in 3D uses texture mapping. This provides a “black-box” solution, often accelerated in hardware, with integrated anti-aliasing. However, standard texture anti-aliasing filters (linear and nearest-neighbor) are not designed for rendering text, and thus provide poor typographic quality.  Our research involves applying appropriate rendering filters to provide 3D anti-aliasing for typographic characters.

Virtual Reality (VR) – Models, Metrics and Metaphors
K. Szabo, M. Beck (1994-1998)
The goal of this project was to elaborate fundamentals and concepts for inter­ac­tion models, metrics and metaphors for Virtual Reality (VR) based applications. Experimental work with various application prototypes using different metaphors made it clear that a successful VR application needs to be well tuned and carefully balanced to meet required user acceptance. The inte­gration of VR and information systems, called ViRIS (VR-based Informa­tion Systems), led to new domains for VR technology such as geography and tourism with powerful opportunities.
Later the work also included the realization of interactive VR application prototypes such as building-walkthroughs in architecture, visual penetration into anatomic objects in medicine, interactive modeling in physics and chemistry, dynamic scene loading for interactive fly-overs in geography, etc.

Distributed Processing for Interactive Particle Motion Simulation and Molecular Dynamics
Chr. Stern, E. Stoll, W. Harris (1995-2000)
This work comprises the conception and implementation of an experimen­tal system architecture for the real-time simulation and interactive scien­tific visualization of molecular dynamics models. The system prototype uses the Lenard-Jones model and its derivatives to determine inter-atomic potentials, forces, accelerations, velocities and positions in space. This new simulation technique was very useful for generating 3D random fractals and analyzing the structure of HTc superconductors. Computationally intensive tasks were performed using parallel distributed computing based on efficient spatial decomposition techniques.

3D Halftoning for the Use in 3D Additive Fabrication Techniques
Q. Lou (1996-1999)
Halftoning is a well-established technique that trades spatial and inten­sity resolution and is used in particular in 2D binary image printing. 3D halftoning is a new technique that allows the approximation of digital volumetric objects of varying material density e.g. porous media for example, by an ensemble of binary material volume elements called vels. In theory, 3D halftoning is basically an extension of the known 2D halftoning process, as widely used in binary printing applications. In practice, however, the development of 3D halftoning algorithms is strongly related to hardware specific boundary conditions, such as particular characteristics of additive volumetric object manufacturing procedures.
The MML first introduced and successfully implemented the technique that realizes the rendition of digital volumetric objects of varying density using the 3D stereo-lithographic additive fabrication technique.

A Virtual Reality Based System for the 3D Interactive Analysis of Medical Magnetic Resonance and Computed Tomography Data (Project Proposal)
Chr. Stern, S. Wildermuth, E. Stoll (1996)
Virtual Reality combines the field of computer graphics and man-machine interfaces with advanced workstation platforms to simulate, visualize, and manipulate real-looking (and feeling) but synthetically generated scenes and models. The pivotal role VR techniques can play in modern diagnostic imaging has been illustrated by the results ascertained within the framework of this interdisciplinary project. VR techniques in combination with stereo viewing allow for a fuller appreciation of the 3D nature of complex organ systems. Interactive virtual non-invasive endoscopic viewing has been shown to be vastly superior to conventional analysis of contiguous 2D images. The corresponding 3D models are based on image analysis followed by subsequent surface generation.
Cancer of the colon is the second most common malignant tumor in the western world. It almost invariably arises from pre-existing polyps. There appears to be a lag time of 3-5 years between development of a colonic polyp and actual malignant degeneration of that polyp into colorectal cancer. Removal of the polyp in this time lag eliminates the risk of malignant degeneration, and thus the risk of colon cancer. Since effective treatment of polyps is predicated upon their detection, a effective and inexpensive screening method has long been sought after. Mass screening with currently available diagnostic tools including barium enema and/or colonoscopy remains too expensive. The calculated cost for preventing one death from colon cancer has been estimated to be in the range of several 100 K$s. Hence, the development of a less expensive, more accurate screening test remains highly desirable.
At the MML a Magnetic Resonance Imaging (MRI) and VR based technique was developed. The technique combines an 3D MRI data acquisition strategy with novel post-processing algorithms capable of reconstructing ‘virtual’ endoscopic images using graphics super-workstations.

An Application Architecture for the Parallel Distributed Simulation of Virtual Reality Based Particle and Molecular Dynamics Systems in Real Time
J. Weissmann, E. Stoll (1997-2001)
This research project focuses on the topic of Virtual Reality and Interactive Scientific Visualization in the context of Particle Motion Simulation and Molecular Dynamics (MD). The goal of this project is the implementation of a platform independent application framework for the simulation of particle systems with arbitrary interaction forces. Furthermore, novel input/output paradigms as well as general parallelization techniques are examined.
The support of arbitrary particle interaction forces is realized by creating a module with a strictly defined interface in which the functions calculating the attraction or repulsion amongst particles are isolated. This concept allows the verification of new interaction forces, by rewriting the interaction module only.
Platform independency is achieved in two ways: First, a few as possible system-dependent functions are used. All platform dependent functions are isolated into modules that can be selectively used by means of conditional compilation. This approach eliminates the need to manage several versions (“single source principle”). Second, since graphic user interfaces (GUIs) are strongly platform dependent, a client- server architecture (TCP/IP) is used that allows data communication between the GUI and the main application. Thus, the GUI is implemented as a client application sending commands as requested to the main application.
The main interaction device (apart from the mouse) being used is the data glove. Here the possibilities of application control by means of gestures are examined. This involves the problem of gesture recognition, which in this project is successfully being solved by using neural networks.

A Virtual Reality Framework for the Design, Optimization and Management of Mobile Telematics Infrastructure

K. Szabo, M. Beck, Chr. Stern (1997-2000)
The expected liberalization of the telecommunication market will challenge the telecommunication industry worldwide. Telecommunication companies are faced with an increasing pressure of competition and complexity of network infrastructure. The need for adequate models for network design and management tools is obvious and will play a key factor for successful competition in the future. Sophisticated network design and management environments, applying Virtual Reality visualization technology, offer the potential to ease these requirements. It is anticipated that Virtual Reality based frameworks will allow the achievement of transparent, efficient and effective ways for network design, optimization and management in mobile telecommunication applications such as paging, cellular phone, mobile computing and global positioning. In this article, a concrete implementation of physical models and advanced algorithms to perform numerically intensive field distribution, wave propagation and visualization computations under interactive control is presented.

The Application Framework MET++ for Multimedia
Ph. Ackermann, D. Eichelberg, F. Rickenbacher, W. Harris (1991-1998)
The rapid development of multimedia applications and presentations is particularly challenging because of the many media and their coordination in space and time and the complex user interactions. The present project developed software engineering methodology and a mature multimedia development platform, the Multimedia Editor Toolkit MET++. In particu­lar, the following issues are addressed with innovative solutions: Support of time dynamic media such as animation, audio and video, and their syn­chronization with new temporal layout and grouping mechanisms; support of 3D graphics as hierarchies of primitives with flexible and extensible 3D manipulation and navigation mechanisms; support of adaption and cre­ativity with a hierarchy of facilities differing in difficulty and expressive power. For the different user groups, the following facilities are available: traditional and temporal document editing, visual programming for rapid development of interactive and didactic documents, application prototyp­ing and construction based on the composition of collaborating and reusable objects, extension of media functionality by sub-classing, and pro­gramming of portability extensions. Research is continuing in particular in the area of visual programming inter-media interaction, while the results are available partially in the public domain and partially from a spin-off company (Perspectix).
The software conception and implementation of this object-oriented framework for the integral handling of the media classes print, audio and video termed MET++ is based on a previous software development framework for the handling of text termed  ET++.
Its basic tasks included the design and implementation of a new class and method library for 3D graphics, interactive animation, sound and compressed video (GL, OpenGL)

A Distributed Rapid Application Development Framework for Mobile-Multimedia: ‘The Virtual Workplace’
A. Meyer (1994-1999)
The ‘Virtual Workplace’ is designed to provide mobile members of distributed work groups with a Multi-Media platform that supports them in communicating with each other, and to retrieve and edit documents and information collaboratively wherever and whenever they need it. The individual project members are supported by a set of user interface, com­munication, and information retrieval agents. These agents act for the user in the back­ground in order to keep him undistracted from his work. No attempt is made to develop new hardware. In contrast, the goal is to conceptualize and implement a software frame­work for the rapid development of mobile Multi-Media applications that will work on numerous current and future hardware devices.

Automatic Additive Fabrication – A View from Business Administration
M. Iacobacci (1998-2003)
There is a large potential market demand for customized products. This fact has been made a big issue in marketing and strategy of business economics, but not likewise in the operational manufacturing domain. The design of concrete efficient IT-based manufacturing processes such as the Automatic Additive Fabrication (AAF) for small quantity of individual solid objects is a highly demanding task. The integration of new business models based on such processes are still leading to vagueness and risky investment decisions. Therefore, the significance of this project lies in its broad inter-disciplinary view by merging business economics and computer engineering science and thereby contributing to the solution of such problems. The expected results will contribute to decision making with respect to acquisition and design of AAF systems. The results should also serve to create projections concerning the application of future generation AAF systems. In addition, they should consolidate the idea if a new paradigm for a real production-on-demand, called ‘digital direct manufacturing’.

‘New I/O Paradigms’ – Gesture Recognition Using a Data Glove
J. Weissmann (1999-2002)
Keyboard and mouse are not very useful devices for navigating in virtual environments and manipulating objects therein. In order to explore new methods for these tasks, a gesture control system has been implemented by use of neural networks which are able to classify static gestures ‘measured’ by a data glove. The Gesture Recognition Module (GeRM) has been designed according to modern object-oriented design principles (so-called design patterns) in a modular and platform independent fashion. GeRM can be easily integrated into any existing application. Future work will aim at freeing the user from the CyberGlove by use of cameras, and it will target at the recognition of dynamic gestures.

The available expertise in automated additive fabrication as a means to conceive a visionary, fully digitized Personal Factory™ of the future is based on a rich platform of R&D competence in algorithm design for representation and reconstruction of 3D free form objects for utilization in a wide spectrum of applications (medicine, mechanics, design, etc.). Equally important is the competence to provide and maintain appropriate software development tools and products to enable data transfer in an automated additive fabrication test-bed environment.
The available infrastructure allowed a view from the perspective of Business Administration to conceive scenarios of automated additive fabrication and application prototyping.

Distance Learning Using Multimedia and Internet Technologies
P. Stucki, W. Harris. M. Path (1994-2003)
The MML is actively investigating new means of disseminating classroom material to students.  Through the use of streaming video and synchronized multimedia, students should be able to view lectures online, as well as review previously archived lectures.
Various methods of preparing course material are being examined.  In December 1997 an experimental live, un-synchronized transmission was presented.  In an on-going project, existing foils shown during the lecture are being prepared for video synchronization.
A new series of lectures from early 1999 has been taped and is being prepared for Internet transmission. Our future activities in this area will involve creating a more seamless, integrated presentation of the materials, as well as adding tools to aid the viewer in navigating and search the online material.  An additional area of inquiry will investigate using e-commerce to provide a complete “virtual university” environment, with students registering for online courses and receiving credits for work accomplished.

Virtual Reality and Real Virtuality Tools for the Biosciences
Chr. Zollikofer, M. Ponce de Léon (1994-2002)
Physical modelling of natural objects in the biosciences is essentially reverse engineering of medical image data. These highly complex data need extensive pre-processing steps prior to manipulating them as Virtual Reality objects on a computer screen or handling them as so-called Real Virtuality (RV) objects, e.g. solid 3D models produced with a rapid prototyping technology (Term coined by P. Stucki). We develop special-purpose graphics software providing users in medicine and anthropology with tools that permit efficient visualization, handling and modification od 2D and 3D data from natural objects and establish an interface to production of physical models.
Computer-assisted Palaeoanthropology is a completely new approach to hominid fossil reconstruction, combining Computer Tomography (CT), Computer Graphics, and Laser Stereo-lithography. Interdisciplinary cooperation of the MultiMedia Laboratory and the Anthropological Institute of the University of Zurich led to development and implementation of the software package FoRM-IT (Fossil Reconstruction and Morphometry Interactive Toolkit). An user-oriented scientific visualization toolkit that permits strictly non-invasive analysis of fossil specimens.

  • External and internal structures of fossil objects are extracted from serial CT image data and reconstructed using a high-accuracy 3D surface generation algorithm.
  • Fragmentary specimens can be completed by assembling different parts and substituting lacking parts by mirroring images of existing fragments. Pieces that had been distorted during the process of fossilization can be reshaped. Computer-assisted morphometric tools permit measurements of complex 2D and 3D features.
  • Reconstructed fossils can be converted to physical hardcopies using laser stereolithography (computer-guided layer-by-layer photo-polymerization) and distributed to researchers and museums.

FoRM-IT is also well suited for medical applications: Concepts from computer-assisted palaeoanthropology, such as object de-composition and re-composition, prove especially useful in Cranio-Maxillo facial surgery. Whenever complex interventional actions are required, stereo-lithographic models produced from patient CT data can be used for manual surgical rehearsal. Exploring surgical strategies with a physical model represents a valuable extension of virtual computer-assisted surgery. FoRM-IT is also used to design customer bone implants. Design of individual implants requires interactive adaptation of pre-existing parts to fit the special anatomical  conditions of the patient. While, at present, stereo-lithographic models can be used in lost-form casting of metal or ceramic implants, direct production of implants with biocompatible material is intended.

Fabrication of Individually Processed 3D Models to Support Surgical Planning Using the Technology of Stereolithography
Chr. Zollikofer, M. Ponce de León, M. Path, H. Stucki (1995-1998)
The same methods of virtual reconstructions of natural objects used in the bisciences can also be used in medicine (e.g. for surgery planning, education, etc.). In such cases the procedure involves the fabrication of individually processed, personal models of anatomic structures (e.g. calcaneus, skulls, etc.).

Computer-Assisted Reconstruction and 3D Morphometry of the Skeleton of Fossil and Extant Hominoids
Chr. Zollikofer, M. Ponce de Léon (1995-2002)
The investigation of significant differences between fossil and extant hominoids has become an important field within computer-assisted anthro­pology, notably with respect to evolutionary and functional implications. Interdisciplinary cooperation with the Anthro­pological Institute of the University of Zurich resulted in a methodological frame­work combining computer tomography, computer graphics and laser stereolithography. A soft­ware package (FoRM-IT: Fossil Reconstruction and Morphometry Interactive Toolkit) is being implemented that provides user-oriented sci­entific visualization tools for non-invasive reconstruction, 3-dimensional morphometric analysis and stereo-lithographic replication of skeletal parts of different species.

The Rubato ™ Music Plattform – Software Development and Maintenance
G. Mazzola, O. Zahorka (1993-2003)
In connection with the Rubat Framework we have developed a Java3D application called PrimaVistaBrowser that can parse databases, which are given in the ASCII-based DenoteX format and represent this data in Java3D instances of the denotator and formclasses. These classes have been implemented in such a way that they meet the most general theorethical approach to denotators as developed by G. Mazzola (using the topos of presheaves over the category of modules). The central achievement is the non-destructive reduction of high dimensional data by so-called folding algorithms and their mapping onto attribute parameters of a general class of multimedia objects, which may have variable geometric shapes, animated behavior, acoustic properties, and haptic response. These algorithms have been traced on a US patent and an international PCT patent in a joint venture with the Unversity of Zurich. Tha application is currently used by music scientists as well as by geographers. The driven hardware ranges from an ordinary PC up to a multiscreen SGI.

Automated Musical Performance: Towards Virtual Performers

St. Müller, G. Mazzola (1999-2004)
The results of recent research in performance theory have been implemented in Rubato, an application for computer-assisted analysis and performance of musical data. In Rubato, a musical performance is a transformation from a symbolic space (i.e. the written score) to a physical parameter space (i.e. MIDI output). Using vector fields is a good way for describing such transformation.  Those so-called performance fields are shaped by different operators that are fed by precalculated weights (metric, harmonic, etc.), which are the results of different analyses of a piece. Ongoing research in performance theory is focused on an extension and refinement of the parameter spaces towards an almost complete specification of the performance process. The extended parameter spaces will be used for sound synthesis directly and, even a step further, for gestural control of a virtual musical performer. The implementation will also be deployed at the Blue-C, a highly immersive cave environemnt buit at the ETH Zurich, thus allowing us to make the synthesized acoustic signals and the virtual performers even more realistic.
