They are simple polyhedron, geometrical polyhedron and multiple polyhedrons. Such shapes are called polyhedrons and include cubes as well as pyramids such as tetrahedrons. The common hendecahedrons are cones, cylinders, some Jason polyhedrons, and the semi-regular polyhedron. The intersection curve of two polyhedrons is a polygon (see intersection of three houses). Their capsids are polyhedrons that appear hexagonal in 2-D. The user essentially creates three concentric, multi-faceted polyhedrons. Euler 3D is a program that allows you to create and manipulate your own polyhedrons. There are also crystals (the small, blue polyhedrons) scattered throughout the map. The polyhedrons, covered with highly polished heat shield, made of aluminium-magnesium-titanium. Various refinements in the shape have been called choppers, discoids, polyhedrons, subspheroid, etc.
