3. Circular fashion

I have been always fascinated by how nature is full of patterns. Some virus make their capsides by assambling together identical pieces of somehow simple protein structures. Fish scales and snail spirals, all follow mathematical and geometrical rules.

And of course, Escher is allways a good inspiration. He is the proof that math and ant could be a nice combination.

In this experimentation class I chose to create my own abstract tile/module, using not the traditional mode with scissors and tape, but digitally, using the open source vector graphic editor Inkscape.

Tessellation experimentation.

1D and 2D tessellation

First, I started with a square.

Then, using the spline tool I drow a green line from the top right corner to the bottom righ corner. The shape of this spline could be changed.

tessselationCollored

Then, we copy the spline to the oposite side of the square.

tessselationCollored

Finally, we join the lines and delete our square.

tessselationCollored

This a simple way to obtain 1D tessellation.

tessselationCollored

If we repeat the process in the top and bottom sides of the square...

tessselationCollored

We obtain a more organic shape.

tessselationCollored

And the tessellation goes 2D.

Radial tessellation

For the fabrication I went with the radial tessellation design. As before, we create a random curve on the right side, and copy it. But this time we rotate it to the right 90 degrees and then paste it to the top corners. The green is the origina curve, and the yellow the copy.

tessselationCollored

Then, we repeat the process with the rest of the corners. Here the blue line is the original, the the black is the copy.

tessselationCollored

We don't need our square helper anymore. Don't forget to convert all the lines to paths and to combine them, for routing purpouses.

tessselationCollored

We can start now to make copies and to fit them where they share shapes. Here we put four of the modules toghether.

tessselationCollored

We can join four of them also this other configuration. This makes our system based on two vertices.

tessselationCollored

It is also possible to copy and paste them in pairs, and then copy and paste the result.

tessselationCollored

This algorithm goes exponential, so it is posible to fill large surfaces very fast. Maybe we can create an algorithm with Blender dedicated to this pourpose.

tessselationCollored

I had the shapes for my pattern, but I needed to join them. For that, I made some paper/scissors tests. I tested this arrow and sloth.

jpg

And here they are together. The fit was firm, but easy to separate.

jpg

I tryied this other, with just a line of diference and the need to fold to assemble.

jpg

And that one resulted on a very strong hold. Better for paper than for the cloth I used, though.

jpg

I ended up to make a sort of combination of both. One join as an arrow, and one as an oval. For making it I just supersposed the geometry.

tessselationCollored

And then cut the sloth at the right lenght.

tessselationCollored

Here we can see the two vertices and the arrow and oval joints.

tessselationCollored

For cutting, we have to separate the pieces. This in unfoutunatelly not good, because we have to waste material. If we could join the pieces as they are, by the borders, it would be a way to maximace the surface. Here we see three of them on the right, already separated for cutting.

tessselationCollored

After saving the file in dxf format, we import it to the laser cutting program.

tessselationCollored

And we set the speed at 100 and the power at 20%.

tessselationCollored

Here are some comfigurations.

I tested the constrction with a light. It might become a nice lamp.

jpg

Altooght the cloth is soft and maleable, the geometry provides structure.

jpg

Here again, with the light.

Another structure made of four units.

From another angle.

Here is the material used.

Alone.

Two pieces.

A single module with an Iron.

Here is the file to be laser cut in svg format.

Here is the file to be laser cut in dxf format.

And Here, and Here, are the files showing the process and are available to make the changes that suit the needs of the downloader.


Felt version

With the idea of exploring and to create a usefull product, other material, size and tag configuration was used. We had some felt material in two colors around, so I changed the units a bit. More tabs were added, they were scaled down to fit on a hand palm. Here we can see two pieces, separated.

jpg

And here we one fit hole/tab.

jpg

Whit just two pieces it is possible to make a little bag. Actually, geometrically they could be represented as two paralell squares. I also found that, for this material and size, a crochet tool could be usefull.

jpg

Almost all tabs fit. Scaling it at human size would allow us to make an utilitarian bag.

jpg

Whit two units we can make tubes that are captable to grow from both sides.

jpg

The planar design of four units, from the front and the back.

jpg

If we join tree units, we obtain a 90° normal angle. Whit that, we go 3D.

jpg

If we still add more units, we can turn the angle to the inside. A cube shape starts to appear.

jpg

If we continue with the process, we can close the cube. We use 14 units.

jpg

The figure is not so good at let light through...

jpg

But the geometry is pretty exact.

jpg

Here form other side.

jpg

All tabs and shapes fit together like a puzzle.

jpg

It is easylly to set the geometry inside-out. We can see the tabs that were hidden in the other configuration.

jpg

The cube could be partially filled with a cozzy material to make a puff. Here our model (one of my mother´s pieces) is sitting in the little soft furniture. Of course we can scale the model to fit the human realm.

jpg

Of course if we fit five pieces together, we can also go pitagorian, and make some dodecaedron-like structures.

Working with repetitive unitis could get tedious fast. A way to automate the assemble of the units could be a nice improvement.

Fortunately, for molecules the process goes in a more stochastical way. An interesting analysis of how this rather simple pieces assembly in more complex structures at molecular modular level is shown in the following video.
