AB: A deterministic geometric procedure resulting in a wide range of complex patterns over one and two dimensions, as transformations of multifractal meassures via fractal functions, is explained. It is shown that such notions may be used to generate distributions that closely resemble observed rainfall distributions over one and two dimensions in a manner that does not require stochastic methods. The ideas are illustrated by showing suitable evolutions of generated rainfall sets, as their geometric parameters are varied. The implications of the results are also discussed.
