Rapidly reconfigurable systems in distributed virtual environments (DVEs) have the promise of reducing development, operational, and training facilities costs for human-operated entities in the DVE. Rapid reconfigurability can reduce costs through reuse of many components of the modeled systems and from the economies of scale achieved by procuring large numbers of identical systems. Our research is intended to develop system requirements and an adaptable software architecture for rapid reconfigurability and, as a spin-off, gauge the limits of rapid reconfigurability supported by current technology. To develop a system in support of rapid reconfigurability among modeled systems, a number of issues must be addressed. These issues include presentation of the controls for the system, support of interaction with the system's controls, physical motion fidelity for all modeled systems, the system software architecture, and achieving correct performance. Because the modeled systems exist in the real world, these issues must be resolved in a way that preserves the training value and fidelity of the modeled systems. We addressed these issues in the context of developing a prototype rapidly reconfigurable photorealistic virtual cockpit (VC). The paper describes the system controls, interaction support, aerodynamics model, and software architecture we used to achieve acceptable system fidelity for the rapidly reconfigurable photorealistic virtual cockpit. In addition, we document the performance of the current system and suggest avenues for further research.
