Modeling seashells

This paper presents a method for modeling seashelfs, suitable for image synthesis purposes. It combines a geometric description of shelf shapes with an activator-inhibitor model of pigmentation patterns on shell surfaces. The technique is illustrated using models of selected sheUs found in nature. CR Categorks: 1.3.5 [Computer Graphka]: Computational Geometry and Object Modeling: Curve, siufue, solid and object represenfutwn. 1.3.7 [Computer Graphka]: l%ree-f)imensionaf Graphics and Reafism. J.3 Life and Medkal Sciences]: Biology. Keyworda: realistic image synthesis, modeling of natural phenomenq seashell, logarithmic helico-spiral, sweep representation, reactiondfision pattern model.
