Abstract:
A method of arranging dimples an a golf ball comprising the steps of:(a) simulating a polyhedron on an outer surface of the golf ball, wherein the polyhedron comprises a plurality of sides, wherein each side connects at two vertices, and wherein each side comprises a plurality of points; (b) simulating a plurality of peat circles extending from the plurality of points on each side to the plurality of points on each remaining side; (c) calculating a plurality of intersection points, wherein each intersection point is defined by &THgr; and &PHgr;, and wherein &THgr; and &PHgr; are obtained by simultaneously solving the equations: Î˜=tan-1&af;[sin&af;(Î˜1)&it;â€ƒ&it;sin&af;(Î˜2)&it;â€ƒ&it;sin&af;(Î¦1-Î¦2)][cos&af;(Î˜1)&it;â€ƒ&it;sin&af;(Î˜2)&it;â€ƒ&it;sin&af;(Î¦1-Î¦2)-sin&af;(Î˜1)&it;â€ƒ&it;cos&af;(Î˜2)&it;â€ƒ&it;sin&af;(Î¦1-Î¦2)]Î˜=tan-1&af;[sin&af;(Î˜3)&it;â€ƒ&it;sin&af;(Î˜4)&it;â€ƒ&it;sin&af;(Î¦3-Î¦4)][cos&af;(Î˜1)&it;â€ƒ&it;sin&af;(Î˜2)&it;â€ƒ&it;sin&af;(Î¦1-Î¦2)-sin&af;(Î˜1)&it;â€ƒ&it;cos&af;(Î˜2)&it;â€ƒ&it;sin&af;(Î¦1-Î¦2)];â€ƒ&it;and(d) positioning a dimple at each vertex, at the plurality of points on each side, and at each intersection point.
