A FAST, VERSATILE RAY-TRACING PROGRAM FOR IBM 7090 DIGITAL COMPUTERS,
Abstract
During the past year the authors have been de veloping a ray-tracing program for use on IBM 7090 digital computers. The basic process within the computer is a fairly simple solution of Snell's law. The great bulk of the program consists of a variety of logic statements that permit the user to perform may seemingly complex oerations with great ease. The entire approach is keyed to fast computation and therefore the cost has been held down to approximately 20 cents per ray path. This, in itself, is a great advantage. It makes the use of ray tracing practical in applications where it might otherwise be prohibitively expensive. Three forms of output are available, any combination of which can be used: 1) The computer will actually draw the ray tracings to scale and many examples of these drawings are included here; 2) the computer will print out the ray-path parameters in a convenient format, including time-delay information not available on the drawing; 3) the computer will put the most significant output parameters on punched cards which can than be used in other different programs.
