A modular low-cost raster-scan colour visual system

University of Sussex, England investigations concerning technical problems of visual representation of realistic scenes in real-time are reported. Flight simulation by such means is difficult to achieve because of its required freedom of movement and orientation in three-dimensional space, coupled with rapid scene changes. The display system described is different from conventional frame store displays in being able to represent moving scenes in real time at low data rates, with an inherently high color resolution that is independent of display resolution. The use of zone management processor modules in the digital hardware of the system leads to easy system expansion at relatively low cost.
