摘要： A golf ball 2 has, on a surface thereof, a rugged pattern composed of a land 10 and a large number of dimples 8. A process for designing the rugged pattern includes the steps of: (1) arranging a large number of generating points on a surface of a phantom sphere; (2) assuming a large number of Voronoi regions on the surface of the phantom sphere by a Voronoi tessellation based on the large number of generating points; (3) calculating centers of gravity of the Voronoi regions and setting the centers of gravity as new generating points; (4) assuming a large number of new Voronoi regions on the surface of the phantom sphere by a Voronoi tessellation based on a large number of the new generating points; and (5) assigning dimples and a land to the surface of the phantom sphere based on contours of the new Voronoi regions.
