Command and Control Visualization
Task 2.1b Objectives
Extend the DIVERSE API to facilitate its use
by Task 2.1a researchers.
Personnel:
John Kelso, Co-PI
Andrew Ray, Dan Larimer, student developers
Year 5 Funding: $110,527

So what is DIVERSE?
• Software to facilitate the display and
creation of device independent virtual
environments
• A framework to support highly
reconfigurable asynchronous distributed
simulations
May 7, 2003
DIVERSE features:
• Applications run unmodified on all supported
devices- real/simulated, local/remote.
– With a variety of input/output devices,
– With any number of navigation and interaction
techniques.
– Additional functionality loaded at run-time.
• Free open source, both cost and redistribution.

DIVERSE has three modules:
• DTK- the DIVERSE Toolkit
– All non-graphical functionality- I/O, networking
– C++ Base classes
• Other modules us it as a foundation
• DPF- the DIVERSE graphics interface to Performer
– Supports Performer graphics
• DGL- the DIVERSE graphics interface to OpenGL
– Supports OpenGL graphics

Task 2.1b year 4 accomplishments:
• Ported DTK to windows
• Ported input and navigation tools from DPF to DTK
– Same tools now used by DGL and DPF
• Created collaborative virtual worlds using DPF
– Multiple networked users share same virtual world
– Awareness tools provide information about other users in
virtual world, and state of objects in virtual world
• DGL beta released- support for desktop and immersive
configurations

DIVERSE in the larger community
In addition to supporting NAVCIITI task 2.1a,
DIVERSE is being used by other VE researchers,
because…
May 7, 2003
Open source model means developments by one can be
used by all:
• DIVERSE has generated an additional $300,000 in non-Navy
funding, but Navy gets to use the work.
Open source license has allowed others to use
DIVERSE at no cost:
• Corporate and Government Research labs.
• Universities and high schools.

Task 2.1b year 5 objectives:
• DGL development:
– Release a stable, documented 1.0 version, including
example programs
– Support for other open-source scenegraphs
• Currently supports Inventor
– Port to other platforms
• Windows, Mac OS X, Sun
• Prototype distributed immersive visualization cluster
• Add security layer to DTK networking

“The work performed at VT under the
NAVCIITI project has had an invaluable
impact on the Navy's initiatives to assess
virtual reality technology within the
context of warfighter needs.”
