Abstract
In his paper ‘A Class of Pleasing Periodic Designs’, Fernandez utilized the union of several sublattices of a square lattice to generate a design on a square tile of the Cartesian plane such that the design, the tile and the lattice have the same rotational and reflectional symmetries. The union of those sublattices may be called a generating set for the symmetric design because the design is composed of certain rotated and reflected copies of the union restricted to the tile. In this article, we use different kinds of generating sets and develop effective algorithms to create aesthetic designs on a tile of a hexagonal lattice such that the tile, the hexagonal lattice and these designs have the same rotational and reflectional symmetries.
