it seems to reply on a number of control/attractor points to pinpoint the curvature.
The process of folding is occuring as the strip travels and distorts through each point, thus creating curvatures that sweep through a complex horisontal path as well as twisting and shearing as it undergoes the bends and changes in amplitude and steepness of each curve.
the curvature is, of course, the main focus.

to suggest that this is a number of developable regular elongated rectangle shapes, and their edges are not linear.
something to especially consider would be how the curves are generated, how is each divided into points, and how the points are isolated
from the rest to allow the useage of them as a vertice for rotation.
There is an interesting

- this would be the second part of the
paper architecture analysis of bending in the physical realm
a series of experiments bending a paper strip to see how it reacts under pressure. a series of control points have been employed to experiment with geometry similar to the one of loop_03. to achieve the
3-point ribbon structure, which is what the case study uses, both attractor - the ones in the centre are pushing the strips in, folding them in towards the centre; the ones around the outer curves ensure the surface retains the volume. and repulse points are in action
similarly, when a number of strips is combined, they share their control points and an
amount of shearing along the z axis is added and shifted as the two pieces of geometry interact with each other as well as the pins
more prominent on a thicker strip, the flat thin body of the strip is warping even when nothing is done aside from pinning it down. folding occurs throughout the entire strip even when only three control points are employed
- in other words it
supports itself in a certain curveature throughout when the same kind of centralisation happens as in loop-03
similarly, the shape changes drastically and drastically moves in the x+y+z axis when the natural edges are twisted.
manual control point edit:
very easy. very quick. not very parametric.
creating curves akin to the ones shown in design presentation of loop-03 proved to be
quite effortless. command ‘control point’ allows for curvature, depth and inset into the centre to be controlled both in curve form, or if lofted (lower) or extruded (bottom)
however this approach completely disregards everything parametric design has to offer. the only visible relationship between elements that is secured and developable is the connection between the curves and control points
+ the curves in the loft.
The decision process for each possible itiration is guided by nothing but my aesthetic preference, which is subjective and unreliable.

kangaroo is a physics engine that makes predictions on how a certain geometry
divided into particles and springs would behave in real life, subjected to real life forces.
i’ve been hoping to utilise it to pr’fold’ my geometry in the same way i’d work with a paper model, using both quad and triangular meshes. initially this worked well as an individual strip
but it was a lot more difficult to produce actual precise geometry with this
this was kinda cool but completely
A number of issues present were kinks, unpredictable ‘bunching’, lack of direct control over the geometry as it unfolded.
