摘要

Image generators (IG), video displays, and wide fleld-of-view (FOV) optical systems are rapidly improving in performance and capabilities. IGs are providing increased polygon and pixel counts, improved texture processing, and increased support for industry standards in smaller and easier to maintain packages. New projector technologies are brighter, higher contrast, less subject to drift, and support higher pixel counts. Simulator optical systems are configured with larger and larger FOVs. These changes provide the promise of greatly improved simulator visual systems in the coming years. Further, the rapid improvement in commercial-of-the-shelf (COTS) graphics hardware and projectors will allow simulator visual systems to take advantage of the resources being applied to the much larger commercial markets. While all of the features listed above are true, and can be objectively demonstrated, it is important to realise the context in which they are made in order to understand the inherent trade-offs. Acceptance of the benefits of all of these features without considering the unstated limitations may well result in a visual system that does not meet training expectations. It is also important to consider the forces for change. If a new feature becomes available which improves performance in one area, but degrades it elsewhere, there will be a certain reluctance to incorporate the new feature as there is risk that the final system may be determined to be unacceptable. If, however, there are other forces at work such as additional training credit from the ability to perform extra tasks in the simulator, then the shortcomings of the new features may be considered to be acceptable. This paper explores the technological advances that have the potential of advancing the state of simulator visual systems, while considering the trade-offs that may result from incorporation of these features. It also explores the forces for change, and the context in which the acceptability of the change is determined.
