    • A method of laying out a dimple pattern on a golf ball comprises constructing a geodesically expanded icosahedron having 60 equal triangular faces (43). Each of the 60 triangular faces (43) includes a substantially identical dimple pattern. The geodesic icosahedron is formed by constructing an icosahedron which is circumscribed by a sphere which has the diameter of the golf ball. A point (39) is determined in each of the 20 icosahedral triangles (35) of the icosahedron by bisecting the three sides (36) of the icosahedral triangle (35). A geodesic focus point (41) is determined by projecting said point (39) onto the surface of the sphere. Each geodesic focus point (41) is connected to each apex (37) of the icosahedral triangle (35) so that each geodesic focus point (41) forms a right regular tetrahedron having a base formed by the icosahedral triangle (35) and three triangular faces (43) which merge at the geodesic focus point (41).
    • 在高尔夫球上布置凹坑图案的方法包括构造具有60个相等的三角形面(43)的测地膨胀的二十面体。 60个三角形面(43)中的每一个包括基本上相同的凹坑图案。 测地二十面体是通过构成二十面体形成的,该二十面体由具有高尔夫球直径的球体限定。 在二十面体的20个二十面体三角形(35)中的每一个中,通过将二十面体三角形(35)的三面(36)平分来确定点(39)。 通过将所述点(39)投影到球体的表面上来确定测地焦点(41)。 每个测地焦点(41)连接到二十面体三角形(35)的每个顶点(37),使得每个测地焦点(41)形成具有由二十面体三角形(35)形成的基部和三角形三角形(35)的右正四面体 在测地焦点(41)处合并的面(43)。
