What kind of tessellation is this?
917743
this tessellation is both a rotation and translation...there is no reflections here...basiccally you notice that you can shift the shape to various places on the tessellation and have it reoccur...this is called translation.  you also notice that if you change the orientatoin of the shape...for instatnce...rotate it you find several occourances found on the tessellation\n\nhowever, this shape does not reflect because it is not symmetric anywhere.\n\nhope this helps, matttlocke

I would guess it is made from rapid prototyping:- Fused-deposition modeling.  It technique is call Extrusion of melted plastic. there is more information that you can find. Just keep looking..

i think its Tera Metric Cubes.

It is a MS PhotoDraw format.\nSimilar program to Adobe PhotoShop.

Artist: Escher\nPhysician-Mathematician: Roger Penrose. He studied quasi-regular tessellation which were lately found to describe the structure of quasi-crystals, that is the chemical structure of some artificial metallic leagues.\n\nOh, I was forgetting another contemporary one: Raoul Raba. Made famous by the French mathematical organization of Kangourou, for which he created the logo.

Here is some information about tiling regular polygons (tiling is also called tessellation):\nhttp://mathforum.org/sum95/suzanne/whattess.html

Square and regular hexagon together \n\nEach decagon is surrounded on each alternate side by a square and a hexagon\n\nAlternately instead of the regular hexagon you could put 6 equilateral triangles tesselated into a regular hexagon or a combination of hexagons and equilateral triangles.

It's a universal drawing file, any CAD system should be able to open it, if it's translated right. I have more luck with them than with STEP (.stp) files.

Textures, edges, but mostly by size.....

May be a Sphere/Circle of defined polygons or Trees.... with infinite edges and finite branching points....

to indicate a solid shape wich has the same rectangular section on each planar parallele to its rectangular base.\nIt has two congruent rectangular faces and four lateral sides shaped as parallelograms (eventually rectangles)\n\nIf all the faces are rectangles, then it's called a parallelepiped

A four-dimensional hypercube.   If you consider time as a fourth dimension, a tesseract would be a cube which has sides of, say 1 metre, suddenly appears, exists for the time equivalent of 1 metre, that's the time it takes light to travel 1 metre, which is 1/ 300 000 000  second,then vanishes.

Here's my answer:\n\nhttp://mudandmuck.com/str2/triangles.JPG\n\nYou didn't say write them out in English, you said describe.  This picture describes the solution.

No it is not.  Go here and look at it yourself.\n\nhttp://www.walter-fendt.de/m11e/line3d.htm

a nine-sided polygon???  can't wait to see other answers...

That would be an octahedron, and it would look like a double square pyramid (two square pyramids put base to base).
