A golf ball surface pattern including depressions and protrusions is
disclosed and claimed. In one embodiment, the depressions and protrusions
are positioned on the ball according to a known dimple pattern, with some
of the dimples being replaced with protrusions. In another embodiment,
the depressions are positioned on the ball according to a known dimple
pattern, and protrusions are positioned on the land areas. Alternatively,
protrusions can be positioned on the ball according to a known dimple
pattern, and depressions positioned on the land areas. The turbulence
generators (dimples and protrusions) that are positioned on the land
areas can be positioned manually or with a distribution scheme. In
another embodiment, the turbulence generators are positioned according to
a scheme based on the principles of electromagnetic theory.
