Advanced Visual Systems Inc., Digital Equipment Corporation, 
Hewlett-Packard Company, IBM, Kubota Computer Inc., Kubota Pacific 
Computer Inc., and SUN Microsystems Inc. AVS Consortium Affiliates 
include Mobil Oil Corporation, and OKI Electric Industry Co., Ltd. 

The 1994 Conference provides an international forum for AVS and 
Uniras users and developers to share information and exchange ideas. 
Advanced Visual Systems Inc. recently acquired Uniras, a Denmark-
based supplier of visual data analysis and presentation graphics 
software and software development tools for scientists, engineers 
and programmers. The Conference and exhibition have been expanded 
this year to include the users of Uniras products.

The Conference features technology-oriented exhibitions, lectures, 
panels, training sessions, a poster session and a video theater. Users 
will present examples and case studies on the use of AVS and Uniras 
products in a variety of application areas.

PROCEEDINGS

distribution free of charge to Conference registrants. Additional 
copies of the proceedings may be purchased separately through 
Advanced Visual Systems Inc. after the Conference.

COME JOIN THE REVOLUTION
The Boston area has seen many revolutionary advances in computers 
and graphics hardware and software, from the X-Window 
Consortium's work at MIT, to advances in PC's, minicomputers, 
workstations and now massively-parallel supercomputers. At 
Advanced Visual Systems and UNIRAS, our own contributions include 
one of the earliest developments in raster graphics technology by 
Mikael Jern, founder of UNIRAS, while working on inkjet printers for 
Applicon in Massachusetts. And of course, the contributions of Dave 
Kamins, and the Massachusetts-based AVS development staff who 
brought us the AVS product line.

As AVS users we work at the leading edge of a variety of fast-
moving technology trends which, with no exaggeration, can be called 
a revolution: 

	Ever increasing desktop power
	Advanced visualization techniques to aid scientific discovery 
and industrial productivity
	Configurable, extensible end-user applications using object-
oriented visual programming techniques
	Rapid application prototyping and development; and On-line, 
network-wide collaboration between AVS users through the 
	International AVS Center (IAC)

This year Boston will be the site of a different type of revolution. 
Advanced Visual Systems Inc. and the AVS product have enjoyed 
tremendous growth in the past year. The user base has expanded 
rapidly, and AVS Inc. acquired Jaguar Software and Uniras in 1993. 
AVS has continued to be a favorite for visualization in the scientific 
community, and has taken on a revolutionary role as a premiere 
application development framework for technical software 
developers. With new AVS visualization and application development 
framework products just around the corner, along with a new family 
of offerings resulting from the Uniras acquisition, the changes are ... 
well revolutionary!

The International AVS Center has also had a great year. With more 
than 500 modules available on the FTP site and thousands of users 
taking advantage of the AVS modules, the AVS Network News 
magazine, and the email hotline, the IAC is one of the industry's 
most unique and standout successes. 

Thanks to all of you, the conference has grown from a small 
gathering in 1992 at MCNC in Research Triangle Park, NC to one of 
the richest conferences available today on graphics, visualization 
and application development. Hundreds of attendees are expected 
this year from around the world. Please join us in Boston in May to 
hear about all the exciting news.

As pioneers, we inevitably become evangelists, trying to get our 
colleagues and co-workers involved - trying to get them to -
