Process for designing rugged pattern on golf ball surface

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.

1. A process for designing a rugged pattern on a golf ball surface, of a golf ball, the process comprising the steps of:
(1) creating a phantom sphere corresponding to the golf ball surface of the golf ball; (2) arranging a plurality of generating points on a surface of the phantom sphere; (3) assuming a plurality of Voronoi regions on the surface of the phantom sphere by a Voronoi tessellation based on the plurality of generating points; (4) calculating a center of gravity of each of the Voronoi regions and setting the centers of gravity as new generating points; (5) assuming a plurality of new Voronoi regions on the surface of the phantom sphere by a Voronoi tessellation based on the plurality of the new generating points; and (6) assigning dimples and a land to the surface of the phantom sphere based on contours of the plurality of new Voronoi regions; and (7) making a rugged pattern including dimples and lands on the golf ball surface based on the assigned dimple and land on the surface of the phantom sphere.
