ABSTRACT:
A golf ball includes noncircular dimples having smooth bottom surfaces; a method for designing the golf ball is disclosed. A noncircular dimple DNChas a border line which is a boundary line on the surface, the boundary line formed by connecting segments at some connecting points. The segments include at least one type of line segments LS and smoothly curved segments CS. A bottom surface BS of the noncircular dimple DNCincludes at least five facets formed of at least five curved reference lines RC, each connecting a reference point A and one of at least five border points B, and each being tangential, at the reference point A, to a reference plane RP inside a virtual sphere having the radius of the ball, the reference point A set on the reference plane RP, the border points B set respectively at positions on the boundary line excluding the connecting points.
