We present an alternative formulation of the phase field method for modeling interfaces. In this approach one works directly with integral equations instead of differential equations. The technique allows one to derive, from microscopic potentials, the surface tension and macroscopic conditions at the interface. In the last section a numerical example is given to illustrate the use of the technique. For a given form of interaction potential, the surface tension and its anisotropy are calculated from which we construct the equilibrium shapes.
