Voronoi tessellation, designed and folded by Nicolás Gajardo Henríquez. This one looks like a picture in perspective but, actually it isn't. Voronoi's Diagram was a focus in my exploration of irregular tessellation years ago, and is the start point on my peacock design.

Folded from a sheet of hand-made abaca and flax paper.
This pattern was generated by dropping a pen onto the flat sheet of paper, to create random points on the paper. The voronoi folding process was then completed using these points as the centroids of the folded polygons.
A Voronoi diagram is a division of a space determined by distances to a specified set of points. It is the mathematical construct that determines bubbles, cellular growth and most other "packing" models of fluid substances. Each entity (bubble, cell, etc.) is marked by a point, and the space is constructed around that point such that it tries to balance the divides between the points.
This is The Final.

Size 2000 x 1500 x 370 and 2000 x 750 x 325 mm, made from white/transparent PF-coated 9mm plywood. High shelf generated and optimised for 75% magazines and large art books. Low shelf generated and optimised for 50% large art books and 50% regular soft and hard cover books.
I normally keep WiP photos (of anything, not just Lego) to Facebook, but I thought this was fun enough to post here too. :)
Voronoi embroidery. Silk, wool, cotton chain stitched to linen. Because maths is beautiful (even if my photos aren’t great).

This example shows how twist fold is defined. For any polygon you can make the same algorithm and find the key points to build the fold. Voronoi gives the basic geometry for obtain the boundary of the twisted polygon, in fact you can define several twisted polygon for the same twist fold.

I took 5 pictures of an ornamental birch tree from different angles, by St Edward's church, Leek, Staffordshire.
Then, I wrote a program to form a composite of all 5 using a Voronoi cell mosaic, to create a Cubism-style effect.

...ohne ihn wäre unsere Umgebung nur halb so interessant.
Ob die Anordnung dieser Fahrrad- oder Haltebügel besonder viel Sinn macht? Ich zweifele! :-))
Noch ist es hier eher einfach, wenn der Rost nämlich noch Löcher zeigen soll - wie damals bei meinem Fass, dann müsste ich noch wesentlich mehr Aufwand treiben. So soll's aber erst einmal genug sein.
Immerhin ist das ein weiteres Teil einer Szene, an der ich schon seit langem, aber mit Pausen, sitze.

using qgis 2.10 to render, using the new drop shadow drawing effect. Inspired by this article on StrangeMaps
The map shows whether or not your nationality would change if you were allocated nationality based on the nearest existing capital city, rather than existing country boundaries.
If you live in an orange area, you live closer to some other country's capital than you do to your own.
The USA, for example, would cede territory to Canada, Cuba, Mexico, Japan, Iceland (!) and Barbados. Iceland seems a stretch until you remember that shortest lines can cross the poles :)
A normal voronoi tesselation on a mercator map won't cut it here, as distances are not preserved across the whole map. This means going down the voronoi route results in some odd results, like Mexico grabbing the west coast of Canada.
Distances were calculated over a discrete 0.5 degree regular grid using the Vincenty formula, so the distances take into account the fact that the world is round and ever-so-slightly squished.
Here's a version showing the how the country boundaries would look.
With initial code from @unpixelled on the Stud.io Discord and a day's worth of poking under the hood of the Eyesight renderer, was able to come up with this version of a Kintsugi custom color.
I always thought that Eyesight was the Cycles renderer from Blender 2.79. Turns out that's not *quite* correct. The Voronoi node included with Eyesight (which is the basis of this material) is much more primitive than the Voronoi node that comes with Cycles in Blender 2.79. This difference could explain other problems I've had creating custom colors. What's in Cycles **may not** be what's in Eyesight.
[I continue to bang my head against the keyboard in frustration, and **really** wish Bricklink / TLG would open source their codebase.]

Designed and folded by Nicolás Gajardo Henríquez from one uncut pentagon.
This is one of many tessellation that I made some time ago while I was developing the Peacock and studying Voronoi´s patterns and how to fold it in paper.
Yep, i'm getting nerdy when tired. As of today, I haven't taken proper vacations for a little less than 12 months. Tired, told you...
A voronoi treemap of the mammals, based on the Tree of Life dataset. Each polygon represents a species, with border color and thickness attempting to show cladistic groupings. The central yellow group is antelopes; warmly colored parts are ungulates. The blue/purple group at the top are various rodents, the irregular mint group to the left the carnivorae (the ToL does not have deeper subdivisions there), the white rectangle is the extinct triconodonts and the blue blob to the upper left is the primates.
The visualisation clearly has some way to go before being ready for prime time, but it is already appealing.
The image was calculated in Matlab. I used a variant of Balzer & Deussen's algorithm without the messy sample points and polygon extraction parts; I have to pay in terms of polygon quality instead, but I think I can fix that.
a test piece from a new working theory of pleating.
polygons are defined by the same methodology used to make Voronoi tessellations; borders are then used as a reference crease along with the central point of the polygon to create the appropriate "fold flat" crease pattern. in this case, you can see the original 1/2 pleat creasings, which were further divided into 1/4 width pleats.
This was a test using random polygons; other methods of more usefulness (applications for use with regular polygonal shapes) are in development.
much fruit on this tree, I think. I hope I am able to refine my ideas enough to make them usable.
if you find this idea interesting at all, please drop me a line at origomi [ at ] mac.com. I'd be happy to talk to you about it.
Playing with the new printer. Trying out the Jared Tarbell recommendation for paper... Im impressed. Hahnemüehle Torchon 275. Superb.
