The present disclosure relates to a golf ball, wherein dimples having an extraordinary flight performance by combining the advantages of both circular dimples and polygonal dimples in the related art, in other words, by arranging the combined dimples that give depth to the face of the combined polygon and circle of the same center on the surface of the sphere, the trajectory is bent due to the influence of wind, which is a disadvantage of the conventional polygonal dimples. It is excellent in flight straightness by eliminating the effect, and when flying after hitting, the vertex region, which acts as a small bluff body, rotates and breaks the pressure in advance, causing a quick turbulent transition, and it becomes like an arc of a circular dimple instead of the sides of the general polygonal dimples.

The presently disclosed subject matter is directed to a golf ball providing improve play characteristics. The disclosed golf ball includes an outer cover comprising a plurality of divots. The disclosed golf ball further includes a central core comprising one or more lightweight materials, such as aerogel. The combination of the lightweight core and the unique divots enable the golf ball to go farther and straighter when hit by the golfer, thereby providing increased performance.

Golf balls having three-dimensional shaped fret areas and methods of making the same are disclosed. The three-dimensional shaped fret areas have at least three edges that meet at an apex point or an apex surface. The three-dimensional shaped fret areas may have a three-dimensional irregular pyramid shape or a three-dimensional truncated irregular pyramid shape. The three-dimensional shaped fret areas create golf balls having increased traction upon impact with the playing surface.

Golf balls according to the present invention achieve flight symmetry and overall satisfactory flight performance due to a dimple surface volume ratio that is equivalent between opposing hemispheres despite the use of different dimple geometries, different dimple arrangements, and/or different dimple counts on the opposing hemispheres.

Golf ball having a generally spherical surface and comprising a plurality of dimples separated by a land area formed on the ball surface, wherein the plurality of dimples includes at least one non-spherical dimple having a non-axially symmetric plan shape and a defined point of maximum dimple depth, wherein: (i) each dimple cross-section of the non-spherical dimple consists of two arcs, each arc extending from the defined point of maximum dimple depth to a point at the land area of the golf ball; and (ii) every point on the perimeter of the non-spherical dimple is located at a radial angle, θ, about a unit circle, where 0<θ<2π, and the edge angle value of the non-spherical dimple at any given point on the perimeter is defined by the solution of an edge angle function f(θ), wherein f(θ) is a non-periodic, continuous, differentiable function.

The present invention provides a method for arranging dimples on a golf ball surface in which the dimples are arranged in a pattern derived from at least one irregular domain generated from a regular or non-regular polyhedron. The method includes choosing control points of a polyhedron, generating an irregular domain based on those control points, packing the irregular domain with dimples, and tessellating the irregular domain to cover the surface of the golf ball. The control points include the center of a polyhedral face, a vertex of the polyhedron, a midpoint or other point on an edge of the polyhedron and others. The method ensures that the symmetry of the underlying polyhedron is preserved while minimizing or eliminating great circles due to parting lines.
