Residential accommodation is available on Friday night and Saturday night. Delegates can register for either the Tutorial, the Institute, or both. In anticipation that a number of individuals may already have copies of Professor Rogers' books and in an effort to eliminate unnecessary costs to the participants, the cost of the course books is not included in the course tuition. These books may be ordered separately as indicated on the Booking Form. POST-INSTITUTE TUTORIAL Professor David F. Rogers will give a one-day tutorial on 'Theory and Applications of Rational B-spline Curves and Surfaces (NURBs)'. Dr Rogers is the designer and implementor of two research and development programs for dynamic real time B-spline surface design. Two very successful commercial B-spline surface design programs are derived from his work. During the last 15 years Professor Rogers has published numerous papers on B-spline curves and surfaces in Journals such as Computer Aided Design, IEEE Computer Graphics & Applications and SIGGRAPH. The discussion of B-spline curves and surfaces in his book Mathematical Elements for Computer Graphics is well known and respected. The tutorial covers the fundamentals of B-splines including a thorough discussion of basis functions and knot vectors, periodic and nonperiodic, uniform and nonuniform B-splines and their application to curves and surfaces. Curve and surface fitting, curve and surface subdivision, Gaussian curvature and curve and surface fairness are also discussed. The course will be given on Saturday, 18 July 1992 beginning at 9.30 am at Reading University. Advance registration for pre- and post-Tutorials is required. VENUE Reading is situated in the Thames valley, about 25 mins by train from London. It is about 30 mins by train to London (Heathrow) airport. Many computer companies are sited in the Reading, Newbury and Bracknell areas. The Royal County of Berkshire is famous for Windsor Castle, and - a bit further away - Hampton Court. There are many local museums and art galleries, and a number of famous stately homes. The Reading Conference Centre is situated on the parkland campus at the University of Reading, a very pleasant and quiet woodland area on the outskirts of the city of Reading. The stylish new residence associated with the Conference Centre offers standards and amenities at the level of a good hotel. Rooms can have en-suite facilities, or can be standard. AUDIENCE This Institute is important for all those requiring a concentrated and in-depth update on the current state of the art in this fast-moving field and to all those with specialist interests in the topics given above. This is a once-only opportunity in Europe to hear leading international experts speak on current developments in their field. Take advantage of this unique opportunity NOW! The fully residential nature of the Institute allows ample opportunity for full discussion and interaction with the speakers outside the formal lecture sessions. Indeed, one of the principal benefits of an Institute such as this is the unique opportunity for informal personal and round-table discussion, and the establishment of personal and professional contacts among scientists from different countries. EXHIBITION There will be an exhibition of selected state of the art products in the area of computer graphics together with exposition of the important aspects of these developments.

Carlbom received a PhD in computer science from Brown University, a MS in computer science from Cornell University, and a Fil.Kand. from the University of Stockholm, Sweden. She is a member of ACM, SIGGRAPH, and IEEE. "Modeling and Visualization of Empirical Data" Summary In this presentation, we explore all aspects of modeling and visualization of empirical data: registration, segmentation, 3D reconstruction and rendering. We give an overview of existing techniques and explore some current research directions. Topics in registration include both manual techniques (blink comparator) and automatic techniques (based on minimization), with and without landmarks. Topics in segmentation include simple automatic techniques (density thresholding), polygonalization techniques (marching cubes), and user-assisted techniques (snakes, or interactive deformable contours). Topics in 3D reconstruction and rendering include volume resampling for interpolation, scaling, rotation, ray-tracing and direct volume rendering. The emphasis is on practical approaches to real applications, with examples from neuroscience, medicine, and geophysics. Prof Roy Hall, Cornell University, USA Professor Hall joined Cornell's Program of Computer Graphics in 1988. He has a background in architecture and structural engineering from Rensselaer Polytechnic Institute, and in computer graphics from Cornell University. His current research concentrates on the relationship between designer and computer in industrial and architectural design applications. In addition to his current work in modeling, he has extensive experience in image synthesis algorithms and color reproduction. In addition to research at the Program of Computer Graphics he teaches courses in both the design and technologies sequences in the Department of Architecture. Formerly Director of Software Development for Wavefront Technologies, Professor Hall has written several commercial image generation systems. He is well known for the book 'Illumination and Color in Computer Generated Imagery'. "Abstraction, Context, and Constraint" Summary The complexity of design and assembly of thousands of components can only be supported by systems that use a variety of presentational abstractions to reduce screen complexity. Reduction of screen complexity is required to allow the designer to focus on important detail, provide uncluttered overviews, reveal relationships, and facilitate interactive manipulation. Providing a wide selection of presentational abstractions to reduce screen complexity often has the side effect of hiding features and context that are necessary in specifying or visualizing constraints and relationships. We explore strategies for managing abstraction, context, and constraints to minimize ambiguity in interaction and presentation. Prof Tosiyasu L. Kunii, University of Tokyo, Japan Tosiyasu L. Kunii is currently Professor of Information and Computer Science in the University of Tokyo. He started work in raster computer graphics in 1968 which led to the Tokyo Raster Technology Project. His research interests include computer graphics, database systems, and software engineering. He has authored and edited over 30 computer science books and published over 120 refereed academic/technical papers in computer science and applications areas. He received the BSc, MSc, and DSc degrees from the University of Tokyo. "Topological Modeling of Phenomena" Summary Visualization models are diverse because their application areas are wide and varied. Examples of attempts to integrate the models occur in the areas of fractals and finite elements. However, little has been done to integrate visualization models based on more general and abstract characteristics derived from the differential or topological aspects. Higher order abstraction modeling allows us to link computer vision with computer graphics in a visual computer. In scientific, industrial, and medical applications it is becoming increasingly important to be able to compare the model with the observed images. Visualizing complexity requires higher order abstraction modeling. Prof Gregory M. Nielson, Arizona State University, USA Gregory M. Nielson is a professor of computer science and adjunct professor of mathematics at Arizona State University where he teaches and does research in the areas of Computer Graphics, Computer Aided Geometric Design and Scientific Visualization. He has lectured and published widely on the topics of curve and surface representation and design; interactive computer graphics; scattered data interpolation; and the analysis and visualization of multivariate data He has collaborated with several institutions including NASA, Xerox, and General Motors and he is a participatory guest scientist at Lawrence Livermore National Laboratory. Professor Nielson is on the editorial board of several journals and he currently chairs the IEEE Computer Society Technical Committee on Computer Graphics. "The Visualization of Scattered Scientific Data" Summary This presentation will consist of a tutorial and survey of methods for modeling and visualizing multivariate data. We will concentrate on the case of scattered volumetric data. Data of this type arises often in practical problems of science and engineering. We will describe several methods for modeling and fitting this type of data followed by several techniques for visualizing the raw data and the modeled relationships. Many of the multivariate modeling methods have a foundation in the area of curves and surfaces and so some of this background material will be covered. A survey of visualization techniques will include isosurface methods and ray casting volume rendering. Volume interrogation methods are now just being developed. The current state of these methods will be surveyed. Prof David F. McAllister, North Carolina State University, USA Dr David F. McAllister is Professor of Computer Science at North Carolina State University in Raleigh, North Carolina. He received his BS degree in mathematics from UNC at Chapel Hill in 1963, his MS in mathematics from Purdue University in 1967 and his Ph.D. in computer science from UNC at Chapel Hill in 1972. His areas of interest include stereo computer graphics, numerical analysis, performance evaluation and fault-tolerant software systems. He is a member of ACM, IEEE, Eurographics, SID, and SPIE. "Stereo Computer Graphics" Summary The presentation on stereo computer graphics will cover topics such as perception, hardware for viewing stereo, input devices, computation of stereo pairs, user interfaces, and stereo animation. Advanced topics will include algorithm speedup techniques, problems in data compression and color quantization, parallax minimization, motion blur, and new autostereoscopic technologies which are stereo pair based. Mr Michael J. Muuss, Ballistic Research Lab, USA Mike Muuss has 15 years of experience in working with advanced computer systems. Since 1981, he has been leading the Ballistic Research Laboratory's (BRL) Advanced Computer Systems Team in research projects concerning CAD/CAE, Graphics, Networking, Operating Systems, Parallel Architectures, and Command and Control.

Mr. Muuss was born in 1958, received a BES in Electrical Engineering from the Johns Hopkins University in 1979, and has subsequently received numerous awards and citations for his work. "Derivation and Analysis of Finite-Element Meshes from Solid Geometric Models" Summary Many types of engineering analyses employ discretizations of integral equations. In order to computationally evaluate these equations, space must be decomposed into a mesh of small elements, or nodes. When very complex shapes are to be studied, it is no longer desirable to use semi-manual techniques. The only feasible approach is to create a solid geometric model of the shapes, and then apply an automatic mesh generation program. This paper will provide a brief history of solid modeling, and review some previous mesh generation techniques. The different types of data that various analyses use (such as nodal models, volume fractions, surface tessellations, and regular and irregular volume elements) will be examined, and several techniques for automatic mesh generation will be compared. A detailed look at a structural and thermal analysis application will be taken, including examining several options for visualizing the results. Finally, techniques for automatic dynamic refinement of the computational domain will be considered. Mr Warren Robinett, University of North Carolina at Chapel Hill, USA Warren Robinett is a designer of interactive computer graphics software and hardware. In 1978, he designed the Atari video game Adventure, the first graphical adventure game. In 1980, he was co-founder and chief software engineer at The Learning Company, a publisher of educational software. There he designed Rocky's Boots, a computer game which teaches digital logic design to 11-year-old children. Rocky's Boots won Software of the Year awards from three magazines in 1983. In 1986, Robinett worked as a research scientist at NASA Ames Research Center, where he designed the software for the Virtual Environment Workstation, NASA's pioneering Virtual Reality project. In 1989, he came to the University of North Carolina as manager of the Head-Mounted Display Project, continuing to work in Virtual Reality. "Electronic Expansion of Human Perception" Summary Computer-generated imagery presented with a head-mounted displaty puts the user inside a simulated three-dimensional world called Virtual Reality. The simulated world may be a fantasy world, or it may be a scientist's model created to explore properties of the real world. But the computer graphics of Virtual Reality need not be isolated from the real world. The two worlds can be optically superimposed, so that computer-generated objects, images, and labels appear to the user spatially superimposed with the ordinary world. By connecting sensors to a head-mounted display, the user can perceive phenonena that are not normally perceptible at all -- the user can see the invisible. For example, using an ultrasound sensor connected to a head-mounted display, a doctor could see inside a patient's body. We call this a "sensory transducer." Prof Dietmar Saupe, University of Bremen, FRG Dr Saupe gained his Dr. rer. nat. in Mathematics in 1982 at the University of Bremen. He has been Visiting Assistant Professor of Mathematics at the University of California, Santa Cruz, 1985-87 and since 1987 Assistant Professor of Mathematics at the University of Bremen. There he is a researcher at the Dynamical Systems Graphics Laboratory with main interests in mathematical computer graphics, visualization and experimental mathematics. He has been involved as speaker and course organizer in five past SIGGRAPH courses on fractals and as the coauthor/coeditor of "The Science of Fractal Images," 1988, and "Fractals for the Classroom," 1991, both from Springer-Verlag. He is one of the contributors to the exhibition "Frontiers of Chaos" which is being shown worldwide under the auspices of the Goethe-Institute. Dr Saupe is a member of the DMV, ACM and SIGGRAPH. "Random Fractals in Nature and their Simulation" Summary Fractals play an important part in the characterization of natural shapes and phenomena, of which we present two basic processes, percolation and diffusion limited aggregation. The second one of these will be demonstrated in a live experiment using electrochemical deposition. Random fractals are the method of choice when it comes to modeling landscapes, clouds and other natural phenomena for the purpose of computer graphical image synthesis. We describe the fundamentals of random fractals and some of the basic methods for their generation. This includes midpoint displacement and spectral synthesis. More recent research focusses on a functional-based approach, the generalization of the Mandelbrot-Weierstrass function and the application of wavelets. Prof Turner Whitted, University of North Carolina at Chapel Hill and Numerical Design Ltd Turner Whitted is co-founder and technical director of Numerical Design Limited, a company that produces image synthesis software. He is also a research professor of computer science at the University of North Carolina at Chapel Hill where he directs student research on geometric modeling and rendering techniques. From 1978 to 1983 he was a member of the Computer Systems Research Laboratory at Bell Labs where he developed rendering systems and algorithms, including the widely-used technique of recursive ray tracing. For several years he has served as a member of the SIGGRAPH conference technical program committee, From 1981 until 1987 he was an associate editor of ACM Transactions on Graphics. He received BSE and MS degrees from Duke University and a PhD in electrical engineering from North Carolina State University. "Architectures for 3D Graphics Display Hardware" Summary The high speed and advanced features of special purpose 3D display processors are a product not only of fast components but of innovative architecture. This talk describes the structure of display processors in a way that shows the differences in features offered by architectural alternatives. A taxonomy is proposed to help understand these differences. We begin with an review of the functions of a display system, followed by a look at how parallelism can be best used in such systems. Extensions to the basic functions, or sometimes collections of existing functions, provide additional features such as anti-aliasing, texture mapping, and realistic shading. An overview of structure starts with the familiar graphics pipeline and progresses through modern embellishment of the pipeline to newer multipass processors. CO-CHAIRS Professor David F.
