GOLF BALL DIMPLE PROFILE
Golf ball dimples having a cross-sectional profile shape partially defined by a Gabriel's Horn curve are disclosed.
1 . A golf ball having a plurality of recessed dimples on the surface thereof, wherein at least a portion of the recessed dimples have a cross-sectional profile including a base portion and a Gabriel's Horn portion, the base portion being defined by the equation:
y ( x )=− C d ,0 ≦x<x 0 ,
where C d is the chord depth, and the Gabriel's Horn portion being defined by the equation:
