Patent ID: 8647219

Claim:
A process for designing a golf ball comprising the steps of: using a computer to provide a phantom surface of a golf ball; determining positions and shapes of numerous dimples on the phantom surface of the golf ball; placing the numerous dimples on the phantom surface of the golf ball; calculating a first data constellation regarding a parameter dependent on a surface shape of the golf ball, based on a surface shape appearing at a predetermined point moment by moment during rotation of the golf ball about a first axis; calculating a second data constellation regarding a parameter dependent on a surface shape of the golf ball, based on a surface shape appearing at a predetermined point moment by moment during rotation of the golf ball about a second axis, the second axis being different from the first axis; determining an aerodynamic symmetry of the golf ball based on a difference between a value obtained from the first data constellation and a value obtained from the second data constellation; and changing the positions or the shapes of the dimples if the difference between the value obtained from the first data constellation and the value obtained from the second data constellation exceeds a predetermined value.
