A conceptually simple computer plotting program has been developed that provides an efficient method of plotting a projection of a three-dimensional surface with remarkable clarity, even if the surface comprises a large amount of detail. The method consists of plotting successive parallel cuts of the surface, each displaced to establish the desired projection. Only that portion of the cut that lies above the previous cuts is then plotted. The plotting sometimes requires several hours, depending on the speed of the computer and on the complexity of the function, but the cost need not be excessive since a relatively small computer can be used. A few of the functions that have been plotted are discussed in some detail.
