45 A mesh geodesic sphere of increasing and decreasing complexity.
47 A geodesic sphere is an icosohedron whose equilateral faces are
48 sub-divided into non-equilateral triangles to more closely approximate
51 The animation shows the equilateral triangles subdivided into four
52 coplanar equilateral triangles; and then inflated outward, causing the
53 sub-triangles to no longer be equilateral, but to more closely
54 approximate the surface of a sphere.
