ABSTRACT:
Provided herein is a golf ball that includes a generally spherical surface and an array of dimples formed on the surface. The undimpled portion of the spherical surface is the land area. At least one of the dimples includes a perimeter, a base, and a sidewall connecting the perimeter to the base. The sidewall forms an edge angle with the ball surface. The edge angle at a particular point on the perimeter is proportional to width of the land area adjacent to the point. Where the land area width is wide, the edge angle is high. Similarly, where the land area width is narrow, the edge angle is low. As the width of the land area in non-tessellated dimple patterns is determined by the position of the neighboring dimples, the edge angle varies cyclically around the perimeter, with the number of cycles corresponding to the number of neighboring dimples.
