Exploring CAVERNsoft Tele-Immersive Collaboratories
at Supercomputing 1998

Jason Leigh, Andrew E. Johnson,
Thomas A. DeFanti, Maxine Brown

Booths at Supercomputing'98 (iGRID/STARTAP/TransPAC, Alliance, Argonne, NLANR) as well as research centers in Singapore, Australia and Tokyo will host virtual reality portals into a number of Tele-Immersion collaboratories at Supercomputing'98 in Orlando, Florida. These collaboratories will showcase a variety of applications developed with the CAVERNsoft Tele-Immersion system (a Globus application). A virtual atrium will serve as a central teleportation point into the various collaborative environments. Once in these environments, remote participants will be able to see each other as avatars (virtual representations of themselves), speak to each other through streaming audio, and interact with the world.

From this web page you will be able to track the people who enter each of the worlds.

Collaboratories that will be shown include:

a.
CAVE6D - a collaborative visualization application for environmental hydrology.
Glen H. Wheless, Cathy Lascara- Old Dominion University; Abhinav Kapoor, Jason Leigh- EVL

b.
Motorola Impact Visualization - a collaborative visualization of the impact testing of a Motorola cellular device
Hong-Yee Wong, Xiaoyan Liu, NUS/IHPC; SiewEng Quah- Motorola, Singapore; Jason Leigh- NCSA/EVL

c.
The Silk Road Cave Shrines- a collaborative tour of the Mogoa Grottoes of Dunhuang in China- an ancient historic site.
Sarah Fraser, Bill Parod, Jim Chen, Dennis Glenn, Harlan Wallach- Northwestern University; Samroeng Thongrong, Tom Frisch, Maggie Rawlings, Mohammed Ali Khan, Yalu Lin, Jason Leigh- EVL

e.
The CAVE Collaborative Console- a set of tools for way-finding in Tele-Immersion. These tools will be used within an architectural space.
Kevin Curry, Kent Swartz, with support from John Kelso, and Dr. Ronald Kriz- Virginia Tech

f.
FutureCamp'98- a number of collaborative worlds created by at a multidisciplinary, virtual reality, day-camp by 9-11th graders, to teach them concepts about modeling in 3D, and Oceanography.
Daniel H. Robertson, John Hicks- Indiana University Purdue University Indianapolis

g. Image-based Three Dimensional Model Reconstruction- this application visualizes a chip manufacturing microscope laboratory at Argonne National Laboratory that was recreated using a new algorithm for image-based reconstruction.
Marek Czernuszenko, Electronic Visualization Laboratory, University of Illinois at Chicago

h. Heliac Plasma Coils- this application shows the main magnetic coil set and a magnetic "flux surface" of the H-1NF Heliac experiment which is an alternative to the tokamac style of fusion device.
Brian Corrie, Henry Gardner, Sam Taylor, Cooperative Research Centre for Advanced Computational Systems, Australian National University

i. LIMBO/VTK- LIMBO/VTK combines LIMBO with the Visualization Toolkit to allow application developers to use the rich set of visualization tools built into VTK to generate sharable three-dimensional objects in LIMBO.
Paul J. Rajlich, Robert J. Stein- NCSA/EVL


All these applications will be instrumented so that bandwidth, latency and jitter of the underlying data paths can be measured through the entire duration of the conference. These measurements will be used to characterize data access in Tele-Immersion in order to inform our future research goals of providing networking quality of service for tele-immersive applications over significant distances and different time zones. The broader scope of Tele-Immersion research includes: database techniques for recording realtime collaborative sessions and for querying and accessing large data stores of scientific and engineering data; realtime graphics techniques and human-centered tools for synchronous and asynchronous collaboration; and networking techniques for ensuring quality of service and for striping of data for maximal utilization of high-bandwidth links.
