SYTLYN - a program for sight line calculation.
The problem described in this article is essentially one of visibility in a steelworks. During work on a development project at Ebbw Vale, a problem was encountered in the siting of work stations in order to give the operatives a good view of the machine they controlled. After reviewing possible manual methods and their advantages and disadvantages, the authors describe the program and its objectives. A computer program was developed to draw, on an incremental plotter, a view of the line from any point. The drawings produced were in a form that gave a 360 degrees view. After discussion of the specification of the shape of objects, and the interpretation of SYTLYN plots, the program's advantages and limitations are discussed, together with some other applications in glare studies, lighting, etc, and likely future developments.
