CAST :: Branching Structures. Plaster panel model cast on a flat sheet of fabric. Structures that divide and spread to gather or distribute loads are found everywhere in Nature. Their beauty and efficiency are clear. However, we rarely build according to this regime. Industrialized building culture relies almost universally on single-axis production machinery: sawmills, rolling mills, extrusions, pultrusions, etc. This mode of production, which forms matter along a single axis of action, produces the uniform-section sticks and sheets that make up our pallet of building materials. To build branching or tapering structures with these kinds of materials requires a multitude of complex, angled, joints and a high level of skill.

In this building culture the rectangle is king. The alternatives to sticks and sheets are things produced by castings or by carvings (for example using multi-axis milling machines). The flexibility of a fabric sheet mold, however, allows us to escape this geometric cul-de-sac. Resources: Free Online Math Calculator and Converter.

Envisioning Julia sets. The Julia set is approximated by the black dots in the image below. The set is generated by a function. The arrows highlight the working of the function. The dark red arrow represents an input point as a direction and distance from the center of the plot. We first double it's angle relative to the right-hand axis and then take the square of the distance from the center, called the magnitude of the point. Then we add a constant value to get the function's output. click the images for an interactive version The Julia set is infinitely deep, but the computer displays finitely-sized pixels.

What we have looked at so far is but one Julia set. But the basic properties of Julia sets we explored above are still valid. Www.enm.bris.ac.uk/anm/preprints/2004r03.pdf. Manual > Attractors.
