If you are looking for something like DIS(Distributed Interactive Simulation)
there is an interesting student project at the Naval Postgraduate School.
Its a large simulation demo, with source and several databases and
uses Performer:

A brief description from their web page:

==============================================================================

The Naval Postgraduate School Networked Vehicle Simulator IV (NPSNET-IV) is
a low-cost, student written, real-time networked vehicle simulator that runs
on commercial, off-the-shelf workstations (the Silicon Graphics IRIS family
of computers). NPSNET-IV has been developed at the Naval Postgraduate School's
(NPS) Department of Computer Science in the Graphics and Video Laboratory. It
utilizes Simulation Network (SIMNET) databases and SIMNET and Distributed
Interactive Simulation (DIS) networking formats. The DIS networking format
is flexible enough to allow multiple players to game over the Defense
Simulation Internet (DSI-Net) or local area networks. The availability
of NPSNET-IV lowers the entry costs of researchers wanting to work with
SIMNET, DIS and follow-on systems. The NPSNET software is written entirely
by the department's MS and Ph.D. candidates. The diversity of their interests
accounts for the broad range of research areas within the project.

Current NPSNET research efforts include: real-time scene management,
physically-based modeling, dynamic terrain, autonomous forces and
expert systems, human-computer interfaces, stereo computer graphics,
head-mounted display integration, DIS integration and development,
constructive combat model integration, terrain database evaluation,
hypermedia integration (Hyper-NPSNET), large-scale networked virtual
environments (greater than 1,000 player worlds), urban terrain,
distributed ship walkthrough, virtual sand table development,
meteorological and atmospheric effects, instrumented test range
integration, and underwater virtual world development and integration.
