Interactive computer graphics is applied to the transmission of visual images through the lower atmosphere. The required input data to the computer consist of an atmospheric temperature profile and light-pen sketches of three objects at various distances from the observer. A transfer characteristic, computed from a bundle of rays leaving the observer, maps each object’s actual location into a corresponding image. The three images, and the horizon line, are then simultaneously displayed on the graphics terminal, thus generating a pictoral version of what the observer would see. This program provides an essential aid to the study of atmospheric refraction.
