Turning the Corner

The three-dimensional viewer, or stealth, has introduced a new set of problems into the large-scale simulated battlespace. Historically, there has been a trade-off in terms of fidelity and the size of a simulation (entity count). However, discrepancies relating to perceived reality in mixed fidelity simulations are being revealed as stealth viewers and their closely related counterpart, the simulated Unmanned Air Vehicle (UAV), become integral parts of larger scale simulations. This paper focuses on a major discrepancy that arises when there are mixed fidelity requirements within a simulation for the representation of entities turning corners. Several different methods to model cornering behaviors are explored. To assess the trade-offs, an instrumented program is used to compute entity motions, deviations from the planned path, and computational costs. This paper is designed to provide implementers with an appreciation of the issues involved, a series of solutions and their associated trade-offs. As we enter an era where the mixed fidelity models are the norm, rather than the exception, resolving their associated interoperability issues will become increasingly important.
