Designed by Continuum Fashion, the N12 if the first completely 3D-printed, ready-to-wear, item of clothing. Previous experiments into the use of 3D printing in clothing have remained purely experimental, haute couture items not available to purchase. This represents the first affordable design that will lead the way for more items fabricated using 3D printing technologies.

“The bikini’s design fundamentally reflects the beautiful intricacy possible with 3D printing, as well as the technical challenges of creating a flexible surface out of the solid nylon. Thousands of circular plates are connected by thin springs, creating a wholly new material that holds its form as well as being flexible. The layout of the circle pattern was achieved through custom written code that lays out the circles according to the curvature of the surface. In this way, the aesthetic design is completely derived from the structural design.” Mary Haung, Continuum Fashion

The N12 is named after Nylon 12 (WSF), the material in which the bikini is 3D printed. Nylon 12 makes an ideal swimsuit material as it is innately waterproof. As well as being the first 3D printed bikini, it is also the first bikini that actually becomes more comfortable when it gets wet.

The N12 was designed using Rhino 3D CAD software and specially written algorithmic script to create the structure of the 3D printed fabric. The algorithm uses a complex ‘circle packing’ equation on an arbitrarily doubly curved surface (the bikini). The size of the circles responds to curvature and edge conditions of the form, creating smooth edges and a responsive pattern.

Digital Fabrics and Patterning

The patterning starts with a curved surface, some geometry to indicate edges and value ranges for the circles sizes and tolerance parameters. The pattern begins placing circles at a point near the edge. Each subsequent circle tries to stay as near to the nearest edge geometry at possible. The circle’s size is determined using this nearness and the local curvature of the surface. Curvier areas get small circles and flatter areas larger, both to help with accurately approximating the surface and to ensure flexibility where it is needed and efficiency of pattern where it is not.

Every time a bend or elbow is encountered in the surface edge, a small gap will be left in the pattern. Gaps will also occur near the middle distances between edges where the placement of the next circle is less certain. After the first level of pattern has been created, these open areas are infilled with smaller circles to ensure complete coverage, and to create a more interesting aesthetic pattern.

One of the goals of the circle patterning system is to be able to adapt it to any surface, at any size. This means that future articles of clothing can be produced using the same algorithm, this could be taken a step further into absolute customization by using a body scan to make a bespoke article of clothing, 3D printed to exactly fit that person only.

Fake or Foto

Fake or Foto? Do you have a good eye?
The Challenge…

Do you remember this popular contest from last year? Now FakeOrFoto has new pictures up.

Today we’re presented with images in movies, on TV, and in the press that are of such good quality we don’t even think to consider whether the picture is of something that exists in reality or if it was generated by computer software. Movies can be considered as being at the high-end of the range of uses for computer generated imagery that mimics real-life, but there are many more day-to-day examples that challenge our ability to tell what’s real and what’s not.

Come along now, you may know that answer. I got 9 of 12 on the first try. How about you? I’ll expect the answer.

Take a reality check…

This material, though a little bit old, will come in useful one day. It gives a good run through of NURBS.

Geometric continuity

nnnaaarrr — Wed, 19 Nov 2008 06:36:52 +0000

Curve continuity

Part 1 Curve continuity

Rhinoceros Help>

Position (G0)
The end points of curves share the xyz coordinate.the curves are position continuous (G0) at the ends.
Tangent (G1)
Tangency measures position and curve direction at the ends. The direction is determined by the first and second point on each curve. If these all fall on a line then two curves are tangent (G1) at the ends. Curves and surfaces with G1 continuity are also G0 continuous.
Curvature (G2)
Curvature continuity between two curves measures position, direction, and radius of curvature at the ends. If the radius of curvature is the same at the common end point, curves are curvature continuous (G2). This condition is not easy to determine by just looking at where the points are located. Curves and surfaces with G2 continuity are also G1 and therefore G0 continuous.

Tools for testing continuity
GCon: You can use ‘Gcon’ command to analyzes the geometric continuity between two curves.
Curve Analysis(Curvature Graph On):This can be used to analyzes theÂ continuity of polycurve.

The curvature graph changes from one value to a different value. (G1/Tangent)

No jumps in the curvature graph.The curvature graph of the first segment connects end-to-end with the curvature graph of the second segment. (G2/curvature continuous)

(Perhaps it can be used to manually adjust the geometric continuity between two curves)

Surface continuity

Part 2 Surface continuity

1) Surfaces share a common edge but the adjoining faces are not smooth or continuous(G0 continuous).

2) Share a common edge and the adjoining faces are tangent(G1 continuous).

3) Surfaces share a common edge and the adjoining faces are curvature continuous(G2 continuous).

Tools for testing continuity

Zebra: You can use ‘Zebra’ command to analyzes the geometric continuity.

Position Only (G0)

If the stripes have kinks or jump sideways as they cross the connection from one surface to the next, the surfaces touch, but have a kink or crease at the point where the zebra stripes jag. This indicates G0 (position only) continuity between the surfaces.

Tangent matches; curvature does not match (G1)

If the stripes line up as they cross the connection but turn sharply at the connection, the position and tangency between the surfaces match. This indicates G1 (position + tangency) continuity between the surfaces. Surfaces that are connected with the FilletSrf command display this behavior.

Position, curvature, and tangency match (G2)

If the stripes match and continue smoothly over the connection, this means that the position, tangency, and curvature between the surfaces match. This matching indicates G2 (position + tangency + curvature) continuity between the surfaces. Surfaces connected with the BlendSrf, MatchSrf, or NetworkSrf commands display this behavior. When you use surface edges as part of the curve network, the NetworkSrf options allow any of these connections.
