Abstract : The objective of the effort was to generate a set of computer programs for the AN/FSQ-67 computer (installed at FTD). These programs would make possible the display of various projections of an object of an IBM Model 2250 Display Unit when the spatial coordinates of significant points on the object are known and to provide for modification of the projections by the addition or deletion of lines, points, and curves and by translation, rotation and scale change. The result of the effort was a set of 66 computer programs which respond to human commands entered through a function keyboard, an alphanumeric console and a light pen. The programs currently are designed to operate in the background mode under the Disk Operating System. When additional core storage on the FTD computer becomes available in the near future, the programs can be modified to operate in the Foreground II Mode of DOS. A follow-on effort will provide computer programs for retrieval of information from files for quick response for photo interpreters. (Author)
