Abstract
As military budgets shrink, the Department of Defense (DoD) is turning to virtual worlds (VW) to solve
problems and address issues that were previously solved by prototype or field exercises. However, there is a
critical void of experience in the community on how to build VW systems. The Naval Postgraduate School's
Network Vehicle Simulator (NPSNET) was designed and built to address this need. NPSNET is a populated,
networked, interactive, flexible, three dimensional (3D) virtual world system. This dissertation covers the
construction and management of the VW in NPSNET. The system, which uses both standard and nonstandard
network message formats, is fully networked allowing multiple users to interact simultaneously in
the VW. Commercial off the shelf (COTS), Silicon Graphics Incorporated (SGI) workstations, hardware was
used exclusively in NPSNET to ensure the usefulness and the portability of the system to many DoD
commands. The core software architecture presented here is suitable for any VW.
