Abstract
A simulator arrangement wherein visual cues are generated by a video system at a display surface (18) spaced from an eye position (14). The image at the display surface is formed as longitudinal boundaries emanating from a vanishing point (VP) positioned a predetermined distance above a fixed horizon (30) image. Hue and texture visual information are developed between the longitudinal boundaries from a memory function (178). The slopes of the longitudinal boundaries are developed as the quotient of the value of the transverse displacement of a boundary from the corresponding position of the eye position divided by a value representing simulated height of the eye position. The arrangement finds particular utilization in conjunction with flight trainers.
