Shape Representation by Zippables
Computational Fabrication research from the Interactive Geometry Lab can turn 3D model files into objects with textiles, connecting parts and forming shape using zip fasteners:
Fabrication from developable parts is the basis for arts such as
papercraft and needlework, as well as modern architecture and CAD in
general, and it has inspired much research. We observe that the assembly
of complex 3D shapes created by existing methods often requires first
fabricating many small parts and then carefully following instructions
to assemble them together. Despite its significance, this error prone
and tedious process is generally neglected in the discussion. We present
the concept of zippables – single, two dimensional,
branching, ribbon-like pieces of fabric that can be quickly zipped up
without any instructions to form 3D objects. Our inspiration comes from
the so-called zipit bags (just-zipit.com), which are made of a
single, long ribbon with a zipper around its boundary. In order to
assemble the bag, one simply needs to zip up the ribbon. Our method
operates in the same fashion, but it can be used to approximate a wide
variety of shapes. Given a 3D model, our algorithm produces plans for a
single 2D shape that can be laser cut in few parts from fabric or paper.
A zipper can then be attached along the boundary by sewing, or by
gluing using a custom-built fastening rig. We show physical and virtual
results that demonstrate the capabilities of our method and the ease
with which shapes can be assembled.
These are so cool. Where can I order a bulk.
