Computer Image Generation CIG visual simulation systems are now being procured for research and as pilot training simulators. Current systems generate scenes that do not provide sufficient velocity and altitude cues. Training effectiveness would be increased by improving this aspect of the visual scenes. This report covers investigations into three approaches to improving visual scene cues. These are generation of contours ridge-like and valley-like features, generation of circular features, and a ground-map technique for generating surface texture. In each of the three areas, the approach was to develop efficient algorithms, to produce scenes for evaluation of the algorithms and illustration of various methods of using the capability, and to estimate requirements for hardware implementation in real-time systems. A goal in all cases was to minimize the use of the edge-processing capacity of the CIG system. In several cases, scenes were prepared to evaluate the effect of applying different algorithms to achieve a desired result.
