Presentation:

Overview of NAVCIITI Task 2.1a&b: Command and Control Visualization: a collaboration between NUWC, NRL, and Virginia Tech to develop of an ASW tactical interface for littoral battle space: CONRAY/MIX.

• Demo CONRAY/MIX

The DIVERSE API used to develop CONRAY/MIX with features for future network centric warfare system development

• Demo DIVERSE embedded in CONRAY/MIX

Payoff:

• Reduced operator workload• Better/more informed decision

making• Improved planning / decision

aids (network- and platform-centric)

Objective:

• Assess potential of 3D to enable rapid and/or accurate assimilation ofcomplex information in a passive target localization context

Goal:

• Evaluate 3D rendering ofcomplex, tactical information ina Navy relevant domain

Overall Technical ApproachOverall Technical Approach

• Develop real-time 3-D simulation and visualization

methodology for a submarine shallow water passive

tracking problem• Acoustic scattering model/scenario generator (NUWC)

- 3D Rendering/GUI development (NUWC/VT/NRL)

- Interactive device interface/integration (NRL)

• Conduct a 2-D VS. 3-D assessment using fleet

operators

• Address high risk “enablers” for DSS FNC

• FY02 Transition to Littoral ASW FNC (Submarine-weapon

connectivity task), Project Mgr - Dr. Les Jacobi

• DSS FNC proposal (FY03)

• ASTO / Tactical Control Program (APB, FY04)

What is DIVERSE?

DIVERSE Toolkit: Networked Asynchronous Simulation• Remote shared memory•Library: C++ Classes to Build Server and Applications•Networked Server: Manage Dynamic Shared Objects (DSOs)•DSO I/O Services: Loaded/Unloaded on the Fly

DIVERSE Graphics Interface for Performer•Uses DTK and Performer to provide:

–Configuration via DSOs–Display-Independent Graphics–Coordinate Systems and Scene Graph–Viewing Frusta–Stereo Graphics–Input from Real and Emulated Devices–Many Navigation Methods
