11 September 1989 Digital Perspective Generation And Stereo Display Of Composite Ocean Bottom And Coastal Terrain Images

Depth sounding data was adapted and used in the generation of stereoscopic perspective imagery. After resampling the soundings into a uniform grid, a lighting function was applied in order to create a shaded gray scale image. The uniform depth grid and the gray scale image were then used in a perspective reprojection program that generates any user-defined perspective view of the data. Simply by generating a pair of such images with a slight difference in azimuth angle, a stereo pair of images may be created. A newly adapted version of this perspective reprojection program has been developed that enables a user to interactively generate stereo perspective "movies" in near real-time, further enhancing three di-mensional perception. Finally, three different types of data -- National Oceanic and Atmospheric Administration (NOAA) depth soundings, U. S. Geological Survey (USGS) aerial photography, and USGS map elevations -- have been combined to create a striking composite three dimensional view of on- and off-shore elevations.
