14. DIVERSE sponsored by Office of Naval Research DURIP Kam Ng NAVCIITI Paul Quinn Lockheed Martin Pat McKenzie

15. DIVERSE is: free (GNU LGPL and GPL) softwarefreeLGPLGPL Consisting of: C++ Application Programming Interfaces (APIs) Utility and Example programs What is DIVERSE? GNU/Linux SGI IRIX Runs on:

16. DIVERSE is for creating Applications like: Crane Ship Simulator with CAVE and motion base Crane Ship Simulator with CAVE and motion base What is DIVERSE?

17. 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

18. DTK Remote Shared Memory is Simulator Glue graphics Local host memory “wombat” wombat dynamics Simulate wombat dynamics File play back graphics Remote Display memory “wombat” wombat dynamics Remote wombat host Stop Reconfigurable

19. The remote shared memory architecture of the DIVERSE API can be used to develop other network centric command and control tactical interfaces. CONCLUSION
