GVU Lab Introduction.

Graphics, Visualization, and Usability (GVU) is an interdisciplinary area which draws its intellectual foundations from Computer Science, Psychology, Industrial and Systems Engineering, and Computer Engineering, and which has application to any use of computers to graphically convey information to users. Typical applications are computer aided design, scientific and business data visualization, multimedia, computer-supported cooperative work, computer-based teaching, image understanding, medical imaging, and user interface design.

The GVU Center has three missions: education, service, and research. In our educational role, we teach the principles and methods of computer graphics, visualization, and usability to members of the academic community ranging from undergraduate students to graduate students and faculty.

Center members teach dozens of courses and seminars. Our service mission is carried out through the Scientific Visualization Lab, a joint undertaking with Information Technology (the campus-wide computer service), to provide state of the art computer graphics hardware and software capabilities to the entire Georgia Tech community. Currently, over 150 faculty, graduate students and staff use the visualization lab's facilities. Our research spans the areas of realistic imagery, medical imaging, image understanding, animation, user interface software, usability, stereo graphics, image quality, and expert systems in graphics and user interfaces. The twenty faculty and staff who are currently actively developing the lab's programs are drawn from Psychology, Mechanical Engineering, Office of Interdisciplinary Programs, Physics, Mathematics, Information Technology, and the College of Computing. An active seminar series and brown-bag lunches brings us together every week to discuss current research topics.

By integrating these three missions together in a single unit, the Center is developing a highly interactive and collaborative environment where researchers unfamiliar with computer graphics can come for help in integrating scientific visualization into their research work, graphics experts and graduate students can share their knowledge with one another and find new and interesting problems on which to work, and students can learn in a melting pot of closely related ideas and collaborations between researchers from multiple disciplines. This intellectually-stimulating environment, complemented by over 30 workstations and other pieces of equipment and over 1200 square feet of lab space, provides a paradigm for the use of interactive computer graphics systems which will be necessary for engineering and scientific research in the 21st century.

The Scientific Visualization Lab.

The purpose of the Scientific Visualization laboratory (a.k.a. "The SciVis Lab") is to provide a new way of seeing massive or complex scientific data. With the powerful graphics workstations and other equipment in the lab, researchers will be able to view results using high resolution, true color graphics, three dimensional solid modeling, and even animation. With all these means of displaying information, researchers will have the capability to comprehend visual patterns and dynamical relationships of great complexity, providing them with profoundly useful tools for analyzing and understanding scientific data. We expect that in developing their methods of scientific visualization, users will not only employ currently available modeling, design, and display software, but they will also forge new types of visualization methods that will be especially suited to analyzing and understanding their data. The staff and facilities of the Scientific Visualization Lab are committed to this enterprise.

The Scientific Visualization Laboratory is operated by the Scientific Visualization Group in the Client Services Department of the Office of Information Technology (OIT).

The facilities are available without charge to all faculty and students engaged in scientific or engineering research.

The lab has graphics workstations, servers, color laser printers, and other peripherals. These are listed in the Hardware section. Also listed in an accompanying section is the Software in the lab. The Sun, SGI, and NT workstations in the GVU Center are accessible with the same account and password used in the SciVis Lab and may be used by SciVis Lab users on a time available basis. Users may apply for accounts on the workstations in the GVU Center by contacting Keven Haynes (keven@cc.gatech.edu) or Steve Park (spark@cc.gatech.edu).

It is our desire that the Scientific Visualization Lab maintains an open and interactive environment where the users feel free to ask each other questions, and to share experiences and software. We will do our part to develop this environment by building libraries of software and providing some expertise (or telling you where you can get it). It may be that once developed, this environment will foster full-scale collaborative efforts that wed different disciplines in the solution of visualization problems. We are already starting some of these efforts by working with computer graphics faculty on selected scientific visualization problems. With the rapid growth in computer graphics faculty and the planned implementation of an academic program in computer graphics and visualization, the potential for further collaboration in this area is great.


Computing Resources.

The GVU Lab contains a wide variety of computing facilities housed in a roughly 1200 square foot area on the second floor of the College of Computing Building. Included in main GVU Lab is the following equipment: Our graphics software includes: RenderMan, WaveFront Personal Visualizer, Data Visualizer and Advanced Visualizer, Iris Explorer, apE, AVS, PV-Wave, IRIS GL, Open GL, NPGL, SunVision, Alias Scetch, Adobe PhotoShop, MacroMind Director, Lightwave, and many public domain packages.

How to Get an Account.

There are different procedures for getting an account in the GVU Lab and the SciVis Lab.

GVU Lab accounts require the sponsorship and signature of a GVU faculty member. You will be able to access all of the systems in the GVU Lab, including the SciVis Lab systems. Specifically, you will be authorized to access all of the Sun, SGI, and NT workstations as well as the Macintosh systems. The Macintosh systems do not require an account. To obtain a GVU Lab account, use the CoC Account Request Form available outside CoC 213 and check the GVU box in the Facilities section. Return the completed form to either CoC 213 or CoC 210 (slip the form under the door if it's closed).

SciVis Lab accounts require the sponsorship and signature of a Georgia Tech faculty member. You will be able to access all of the systems in the SciVis Lab, which includes all SGI workstations, and the Sun systems in the GVU Lab. To obtain a SciVis Lab account, use the SciVis Account Request Form available outside CoC 210 or in the OIT handout bins in the Rich Building. Return the completed form to either CoC 213 or CoC 210 (slip the form under the door if it's closed). For more information on obtaining a SciVis account, please contact the SciVis manager, Markus DeShon.

As a GVU or SCIVIS user, you automatically get an NT account, however you will need to manually activate your NT account:

  1. Log into a UNIX workstation
  2. Type: 'xhost +winframe;rsh winframe wincenter -display hostname:0'
  3. Then quit wincenter and log into an NT system.
For questions regarding GVU or SciVis Lab accounts, please contact help@cc.gatech.edu or markus.deshon@oit.gatech.edu, respectively.


Help!

There are several ways of getting help in the GVU Lab:
We recommend asking questions electronically (i.e. E-mail and USENET news) to expose the question and answer to many people as possible. GIT.GVU is the OFFICIAL newsgroup for news, information, and questions regarding the Graphics, Visualization, and Usability Center. Postings to the newsgroup cover a number of topics, including: GIT.GVU is a campus-wide newsgroup and should be accessible from your prism account or other GT college account. You can access the group via your favorite newsreader, or by typing "rn git.gvu".


Mailing Lists.

A lot of communication at the GVU Center is accomplished with e-mail. There are several GVU e-mail lists (all of which end with @cc.gatech.edu or @gvu.gatech.edu):
