Claims16
A golf ball comprising a plurality of recessed dimples on the surface thereof, wherein at least a first dimple has a non-spherical cross-sectional profile and a chord depth range from 0.006 inches to 0.016 inches, where the non-spherical cross-sectional profile defined by a weighted function, wherein the weighted function is the multiplication of a spherical base profile function g(x) and at least one weighting function w(x) and at least a second dimple has a cross-sectional profile defined by a weighted function, wherein the weighted function is the multiplication of a conical base profile function g(x) and at least one weighting function w(x), wherein at least one dimple of the golf ball has a base dimple profile modified using a profile relative method, wherein
- f(x)=g(x)*(1+w(x))
- wherein the weighting function w(x) is continuous and applied from the dimple center at x=0 to the dimple perimeter at x=d/2 where d is the dimple diameter, and g(x) and f(x) are equal at x=d/2.
A golf ball comprising a plurality of recessed dimples on the surface thereof, wherein at least a first dimple has a non-spherical cross-sectional profile and a chord depth range from 0.006 inches to 0.016 inches, where the non-spherical cross-sectional profile defined by a weighted function, wherein the weighted function is the multiplication of a spherical base profile function g(x) and at least one weighting function w(x) and at least a second dimple has a cross-sectional profile defined by a weighted function, wherein the weighted function is the multiplication of a catenary base profile function g(x) and at least one weighting function w(x), wherein at least one dimple of the golf ball has a base dimple profile modified using a profile relative method, wherein
- f(x)=g(x)*(1+w(x))
- wherein the weighting function w(x) is continuous and applied from the dimple center at x=0 to the dimple perimeter at x=d/2 where d is the dimple diameter, and g(x) and f(x) are equal at x=d/2.

- f(x)=g(x)*(1+w(x))
- wherein the weighting function w(x) is continuous and applied from the dimple center at x=0 to the dimple perimeter at x=d/2 where d is the dimple diameter, and g(x) and f(x) are equal at x=d/2.
