Abstract:
1. A process for designing a rugged pattern on a golf ball surface, the process comprising the steps of: providing a spherical surface with the same diameter as that of the golf ball; assuming a large number of cells on the spherical surface; assuming a plurality of states; deciding an initial state of each cell by selecting one of the assumed plurality of states; determining whether or not to change a state of said each cell based on states of a plurality of cells located adjacent to said each cell; updating the state of said each cell based on the determination; assigning a land or a recess to said each cell according to the state of said each cell; and forming the rugged pattern on the corresponding golf ball surface according to the assigned lands or recesses on the spherical surface, wherein the steps of determining and updating are performed by a reaction-diffusion model of a Cellular Automaton method.
