sections 52 c 54 h 54 l and again in fig1 all the spherical sections have equal radii for convenience by incorporating further outer spherical sections around the central section 52 a 52 c it is possible to provide further complex dimples having both the desired cross sectional structure 42 and central polygons having any number of sides as desired each of the complex dimples 40 a 40 d is preferably the same overall size as a conventional dimple in other words the complex dimples should be dimensioned to be circumscribed by a circle having the same diameter as a conventional dimple about 0 100 to 0 185 inches 2 540 to 4 699 mm with the radii of the circles generated by the intersection of the spherical dimple sections with the sphere of the ball preferably being between about 0 025 to 0 047 inches 0 635 to 1 194 mm in length if the complex dimples are dimensioned much wider the projections 46 a 46 b will become spaced too far apart and their vortex generating characteristics will diminish any combination of the complex dimples 40 a 40 d or further complex dimples made according to the present invention can placed on the surface 26 of the golf ball 20 to either enhance the performance of the golf ball or.
