Abstract : Two systems of models to generate two-dimensional circular patterns are proposed. The first system consists of models which represent growth along the radii, the number of rays being unlimited. Comparison is made with cycle languages and our earlier rectangular model. Catenation and star operation for string languages are extended to radial and transversal catenation, and star operations and closure properties examined. The second system includes developmental models which reflect radial and transversal growth. Radial and transversal generations take place in parallel, controlled by a control set, and describe circular developmental patterns.
