Icospheres at different subdivision levels

In computer graphics, an icosphere is a geometric primitive available in that approximates a sphere as a simplicial polyhedron, formed by subdividing the polygons of a Goldberg polyhedron into their triangular constituents, or equivalently, by subdividing the triangles of a regular icosahedron.[1][2] Icospheres are normally used to achieve a more isotropic (regular) layout of vertices than a UV sphere, and are more suitable in certain settings.[3]
