User:Tomruen/Zonish polyhedron

In geometry, a zonish is a convex polyhedron, related to zonohedra, coined by George W. Hart. Each is constructed as Minkowski sums of an initial seed polyhedron and a set of line segments. The seed polyhedron can include odd-sided polygonal faces which also appear in the zonish forms. A zonish polyhedron can be dissected into the seed polyhedron, prisms extending from the face of the seed, and parallelepiped.

A zonish made from a seed polyhedron and a single segment direction will create an elongation as seen in some Johnson solids. Zonish can keep the symmetry of the original polyhedron by using face normal vectors as segment directions.
