EXPOSITION ART SHOW

The SIGGRAPH conference has become the place to see thelatest computer graphics hardware, software, peripherals, andservices. The exposition is for anyone involved in computergraphics. The John B. Hynes Veterans Auditorium ExhibitHall is open July 27-29.

All phases of SIGGRAPH have demonstrated remarkablegrowth since the first conference in 1974. The exposition pro-gram has grown from a handful of exhibitors in 1975 to 135in 1981. More than 140 exhibitors are expected this year.

Even more important is the diversity of the exposition.Vendors will provide demonstrations of products affecting allphases of graphics including:

* Turnkey applications (CAD/CAM, cartography, imageprocessing, etc.)

* Refresh vector, raster, and storage tube displays* Film and paper hardcopy devices* Graphical input devices* Software support packages* Time-sharing services* OEM products

USER GROUPS

A number of user groups traditionally meet during theSIGGRAPH conference. Scheduled meeting dates and loca-tions will be available in late June. For further information,contact your user group or John French at 713-965-4084.

VENDOR FORUM

The vendor forum will include two days of vendor presenta-tions of new product lines. Presentations will be held in roomsnear the exhibit area at the Sheraton-Boston Hotel. Five dif-ferent sessions will be held concurrently, with presentations inthe areas of Future Applications, Hardware Trends, BusinessGraphics, CAD/CAM, and Education.

SIGGRAPH '82 will sponsor a major juried public exhibitionof artists' computer-generated works. The show will includeexhibits of hardcopy, film, video, and presentations of installa-tions. The selected works will be exhibited in the Sheraton-Boston Hotel during the week of the conference.

CHAIR:Doug Neal, Decision Resources

Data bases and graphics have grown up in different tradi-tions; however, with the emphasis on Information ResourceManagement, graphics is recognized as crucial to both thepresentation and the interrogation of information. Graphicsbecomes the means by which information is presented to theboard of directors as well as the technique by which theanalyst examines the data in order to determine what to showto the board. Graphics is the way that executives who havepaid for all the data bases and associated computing activitiescan benefit from those expenditures. Both board memberand analyst can review information much faster when pre-sented in graphical form. Case studies will be used to demon-strate the benefits and conflicts that occur when graphics anddata bases are brought together. Trade-offs between variousimplementation strategies will be examined. Recent offeringswhich link graphics and data base systems, such as IDMSand System 2000, will be discussed.

LECTURERS:Doug Neal, Senior Vice President, Decision Resourcesand noted experts on data base management systems.

Doug Neal has extensive experience in both designing large-scale business systems and in performing graphics hardwareand software needs assessments for large corporations andU.S. federal agencies.

He is a Senior Member ofthe IEEE and a member of ACM, AAAS, and Sigma Xi.

WHO SHOULD ATTEND?The lectures will assume a certain level of calculus back-ground and some familiarity with computer graphics displaydevices. People involved both managerially and technicallywith computer-aided design of three-dimensional objectswith freeform surfaces should find the course useful.

CHAIR:Richard F. Riesenfeld, University of Utah

Introductory concepts as well as some specialized currentresearch topics will be presented at an intuitive, tutorial level.An introduction will cover basic interpolation and approxi-mation curve forms leading to polynomial and spline repre-sentations. An overview of subdivision techniques and theirrelation to discrete splines will be given. Lectures describingextensions to surfaces and display algorithms will be in-cluded. The last lecture will be on the user interface require-ments.

LECTURERS:Richard F. Riesenfeld, University of UtahWilliam J. Gordon, Drexel UniversityElaine Cohen, University of UtahJeffrey M. Lane, Calma/GEA. Robin Forrest, University of East Anglia, UK

Richard Riesenfeld is Chairman of Computer Scienceand Head of the Computer-Aided Geometric Design Group(CAGD) in Computer Science at the University of Utah,where he joined the faculty in 1972. He has published andconsulted in the area of computer graphics and the academicissues and the industrial applications and motivations in thefield. The B-spline method of curve and surface design, whichhe proposed in his doctoral thesis, is used by many industriesin many countries. His major research focus for the last twoyears has been in discrete splines and their applications in anexperimental CAGD system called Alpha-1. This system in-volves some new modelling ideas that are useful in com-bining computer graphics, geometry models, and othermodels.
