The Interactive Image Display System.

摘要

IMAGE is a high-performance interactive computer graphics program for displaying 2-D graphs and perspective projections of 3-D data. The development of IMAGE was prompted by the need for a tool for solving numerical fluid dynamics problems, but it was designed to be general enough for use in graphically representing input and output data in any problem area. The IMAGE input data to be examined may be produced by any FORTRAN program with simple WRITE statements. The data can then be displayed, studied, manipulated, and modified by the user. Publication quality hardcopy output of selected views is easily and quickly obtained from the CALCOMP or SC 4060 plotters. IMAGE is designed to run quickly and efficiently. Speed is attained by minimizing the number of requests required to perform a function. Efficiency results from programming each transaction as a separate module, called a task. These tasks are loaded into core memory only as needed. Virtual memory techniques also save core storage. The program is available for general use on the Tektronix 4014 and the CDC IGS 274 terminals linked to the DTNSRDC CDC 6700 and 6400 computers. (Author)
