Abstract
We present a method for modeling gravitational lensing as gradient-index lenses in the ray-tracing software CODE V. When applied to gravitational lensing by the Sun, these models yield results in agreement with theoretical and experimental results. The extension of this type of model to "lumpy"astronomical objects whose lensing behavior is difficult to predict with traditional methods is discussed.
