Zonohedron


Zonohedron. Consider any star of line segments through one point in space such that no three lines are coplanar.Then there exists a polyhedron, known as a zonohedron, whose faces consist of rhombi and whose edges are parallel to the given lines in sets of .Furthermore, for every pair of the lines, there is a pair of opposite faces whose sides lie in those directions (Ball and Coxeter 1987, p ...

A zonohedron is a convex polyhedron that is centrally symmetric, every face of which is a polygon that is centrally symmetric.Any zonohedron may equivalently be described as the Minkowski sum of a set of line segments in three-dimensional space, or as the three-dimensional projection of a hypercube.Zonohedra were originally defined and studied by E. S. Fedorov, a Russian crystallographer.

A zonohedron is a convex polyhedron; the zonohedron itself and all its faces (of all dimensions) have centres of symmetry. A sufficient condition for a convex polyhedron to be a zonohedron is that its two-dimensional faces have centres of symmetry. Any zonohedron is the projection of a cube of sufficiently high dimension.

A zonohedron is a polyhedron in which every face is centrally symmetric. Zonohedra can be defined in various ways, for instance as the Minkowski sums of line segments. The combinatorics of their faces are equivalent to those of line arrangements in the plane.

Zonohedron is a simple command-line program that computes a zonohedron out of a collection of 3D vectors. Zonnohedron is a generalization in N dimensions of Zonohedron. Both are written in C++ and thus available for every platform, Zonohedron it's quite fast and can process zonohedra with thousands of generators in a short time.

Similarly, any zonohedron can be made equilateral, i.e., unit length vectors can be chosen for the star. If a zonohedron is made entirely of parallelograms and has more than three zones, one can remove any zone from it and assemble the two disconnected pieces to obtain a smaller zonohedron, with one less zone.

To make this zonohedron with Stella 4d (available as a free trial download here), start with a dodecahedron, and then perform a zonohedrification based on both faces and vertices.It is similar to the rhombic enneacontahedron, with thirty equilateral octagons replacing the thirty narrow rhombic faces of that polyhedron.

A zonohedron bounded by parallelograms and rhombs. It is related to Kepler's Rhombic Dodecahedron, and has cyclic symmetry. Every edge lies in one of 24 different directions (the 24 vectors which determine this zonohedron); note that any one edge-direction determines a zone of faces which girdle the zonohedron.

Zomes are zonohedron domes, made from rhombi.. Interactive 3D tool: Click here. The beauty of zomes is that their shape comes completely from the properties of rhombi - only the bottom row of triangles is chosen by the user.

A zonohedron (by one restrictive definition) is a convex polyhedron all of whose faces are parallelograms. (less restrictive definitions, below, allow other types of faces.) You can get a feel for them by exploring and comparing a "random" zonohedron with 42 faces and this nicely structured rhombic enneacontahedron, shown at right, a zonohedron ...

A zonohedron is just a three-dimensional zonotope. Zonohedra include many familiar polyhedra including cubes, truncated octahedra, and rhombic dodecahedra. Towle recently described Mathematica code for polar zonohedra, generated by vectors evenly spaced around a circular cone. This notebook contains code for constructing zonotopes and ...

Zonohedron is a simple command-line program that computes a zonohedron out of a collection of vectors.

Every face of a zonohedron is a zonogon, and every zonogon is the face of at least one zonohedron, the prism over that zonogon. Additionally, every planar cross-section through the center of a centrally-symmetric polyhedron (such as a zonohedron) is a zonogon. References

Here is the dual of this zonohedron, which has 1532 faces, 1230 vertices, and 2760 edges. This "flipping" of the numbers of faces and vertices, with the number of edges staying the same, always happens with dual polyhedra. I do not know of a name for the class of polyhedra made of zonohedron-duals, but, if any reader of this post knows of ...

This is a polar zonohedron, with 12 zones (6 clockwise, 6 counterclockwise), each 1/8th of the total circle of 48 zones. The top and bottom rings are there to eliminate the very thin top and bottom parts of the zones.

The term "Zome" comes from "zonohedron" + "dome", and was coined sometime in 1970 by Steve Durkee.A zonohedron is a form which can fill a given space seamless, the most popular zonohedron is the cube. Strictly speaking, the zomes featured here aren't zonohedra anymore; it seems the term "zome" also applies to unusual dome constructions.

I've recently been looking into Zonohedrons and Rob Bell made beautiful ones. I had a play with the free Polar Zonohedron Sketchup Plugin and thought about playing with the geometry using Processing.So far I've open up the plugin/Ruby script and tried to port it directly, but I am not experienced with Ruby and have been using the Sketchup Ruby API reference.

The Frequency is a positive integer value which must be 3 or greater. This defines the number of vector generators of which the entire polar zonohedron is formed. Shown above is an 8 frequency polar zonohedron - hence the eight petals which converge at the top.

This is a polar zonohedron, with 12 zones (6 clockwise, 6 counterclockwise), each 1/8th of the total circle of 48 zones. The top and bottom rings are there to eliminate the very thin top and bottom parts of the zones. The thinckness of the 'wires has been increased to 1.5 mm to print in the steel materials.

Each rhomb of a polar zonohedron is divided into two triangles. Then the zonohedron is shaped by changing the vertical coordinates of the vertices of the triangles according to selected portions of a sine wave. This means that the poles of the polar zonohedron are moved symmetrically or asymmetrically to produce various shapes, such as a raindrop, heart, bullet, barrel, ellipsoid, or submarine.

Every convex parallelohedron is a zonohedron of one of the five com-binatorial types shown in Figure 2. Conversely, every convex zonohedron of one of the five combinatorial types in Figure 2 is a parallelohedron.4 Fedorov's proof is not easy to follow; a more accessible proof of Fe-dorov's result can be found in [2, Ch. 8].
