A golf ball has a spherical body having a mold parting line at the equator thereof by which the body is divided into a top half sphere and a bottom half sphere of equal dimensions, the molded partition line having no dimples thereon; an axis passing through the center of the plane which is defined by the mold parting line, the axis defining two poles at the intersection thereof with each of the half spheres, and being perpendicular to the plane; a first set of four identical spherical regular triangles and six identical spherical right triangles distributed over the surface of the top half-sphere, and serving as a constraining pattern for dimple distribution; a second set of four identical spherical regular triangles and six identical spherical right triangles distributed over the surface of the bottom half sphere and serving as a constraining pattern for dimple distribution, said second set of spherical triangles being a mirror image of the first set of spherical triangles but rotated by 60 degrees centering around said axis; and a series of dimples whose configuration being determined so as to fit in said constraining patterns, at least one of said configurations being determined to exhibit optimum performance with a tailwind, one being determined to exhibit optimum performance into a headwind, one being determined to exhibit optimum performance under no wind and other configurations being determined to exhibit optimum performance under low altitude, high altitude, low temperature, and high temperature conditions, respectively. |
