A direct synthesis method for analyzing the light curves of close binaries is described. The intention is to keep the programming and computational effort to a minimum, consistent with the accuracy attainable by photoelectric photometry. To this end an ellipsoid-ellipsoid model is adopted and the geometric properties of ellipsoids are exploited; the reflection effect is dealt with semi-analytically; and a creeping random search technique is used to converge on the solution. The method is straightforward to program and can synthesize a light curve from prescribed elements in a few minutes on a medium-speed computer. There is a discussion of the accuracy and limitations of the method.
