Texture as a visual cueing element in computer image generation. I - Representation of the sea surface
Abstract
The objective of this paper is to advance hypotheses about texture as a visual cueing medium in simulation and to provide guidelines for data base modelers in the use of computer image generator resources to provide effective visual cues for simulation purposes. The emphasis is on a texture decoration of the earth's surface data base in order to support low-level flight, i.e., flight at elevations above the surface of 500 feet or less. The appearance of the surface of the sea is the focus of this paper. The physics of the sea's appearance are discussed and guidelines are given for its representation for sea states from 0 (calm) to 5 (fresh breeze of 17-21 knots and sixfoot waves, peak-to-trough). The viewpoints considered vary from 500 feet above the mean sea surface to an altitude just above the wave crests.
