In today's visual technology there are many parameters, the values of which must be correctly chosen, to achieve an effective visual training simulator. Some of these parameters are resolution, brightness, contrast ratio, real image versus infinity image, collimation, field of view, field of view gaps, realism, target and area of interest fields of view, detectability and aircraft discernibility relative to slant range. True perspective and scene continuity across juxtaposed channels also are important parameters and are the subject of this report.

If single displays are used, scene continuity and true perspective is not usually a problem but most wide-angle visual systems today are composed of several optical windows, projectors or monitors to form a wide field of view while retaining good resolution.

When a specification requires juxtaposed displays, the designer must solve the problems of scene continuity with distortion-free perspective.
