A geodesic dome is a type of structure shaped like a half of a sphere or a ball. Think of a soap bubble on the surface of water. This structure is comprised of a complex network of triangles that form a roughly spherical surface. The more complex the network of triangles, the more closely the dome approximates the shape of a true sphere. The category of Geodesic Domes Fall in to are 2v 3v 4v 5v 6v and so on. Dome calculators can be found Here on the internet and can be quite beneficial to you in calculating the building of your own Geodesic structure.
