This paper presents a method for modeling seashells, suitable for image synthesis purposes. It combines a geometric description of shell shapes with an activator-inhibitor model of pigmentation patterns on shell surfaces. The technique is illustrated using models of selected shells found in nature.Keywords: realistic image synthesis, modeling of natural phenomena, seashell, logarithmic helico-spiral, sweep representation, reaction-diffusion pattern model.
