Contracting rigid-foldable tubes

After the introduction of converging planes, I extracted one of the resulting curves and reintroduced convergence, but this time the limiting element was a point. A few tests and adjustments resulted in selection of two ‘visually optimal’ shapes. Thinking of small-scale structures I envisioned them as tents for one person. The next step was to explore different approaches for inside-outside movement with a system of foldable elements that allow opening/closing.

The first proposal is based on the idea of curved rigid-foldable tubes. Their structure would allow movement along tracks (rails) as they contract/expand to open/close. At this point, they can be observed as cells that group to form a small organism – camp on the island.

Trying to connect the proposed structures with the context, I reflected on the site-selection task. I concluded that the identified pixels with irradiation above a threshold value are to be used as important factor for arranging the elements. Thinking of the approaches for correlating them, I lost track of the true meaning of these pixels and took a ‘wrong direction’ in the process.

The proposal included two ways of manipulating the pixels into shapes with MATLAB and Rhino. First is the Point Spread Function (PSF), which generates Gaussian distribution of the pixels in a selected region (see graphs that visualize the algorithm). This gives a certain degree of blurring which is determined by the x- and y-axes and an intensity factor. The second proposal uses a Motion Function (MF) that is adjusted for different directions and intensities. The outcomes in both cases are treated as height maps that translate to lines which define their shape. Then, one of the results is chosen to try the principle of curved rigid-foldable tubes.

At this point the obtained product contradicts with the idea of utilizing irradiated pixels for daily activities. The structures on top of them do not justify their purpose, so I will iterate back to the previous step by further developing the contracting-cells proposal.
