Hi Dana, yes ... it has been the initial idea to use this script for a foldable material ... extended precursors for production purposes have been used for a design-build-project of a bigger scale @ the TU Darmstadt in 2010 and a little version with more complexity for an exhibition @ the MAKK in Cologne in 2012 ... the script will develop its origami qualities with a bended reference surface in rhino ... it will behave like this depending on the curvature ... have fun

Hi Ante, Is this Yoshimura script foldable pattern? Can I use this pattern as a method for foldable material?

just updated yesterday´s 2016 version once more with a filter for border elements that have less than 2 borders ... the spiraling surface for input purposes is created with standard rhino functions (2 lofted and spiraling curves)

thanks!

Hi there... I have appended an updated version of the script above which uses Lunchbox and can recognize partially closed surfaces to avoid seams in the folds... The folds only appear if the breps have curvature (see older comments below)... have fun

Hi ante, the result is amazing, I would really love to study this definition, can you please post a better resolution image? or can you send me the jpg of it? carlo28.richi@gmail.com
From what input geometry do you start?
I'm wondering if the twisting we can see in the final rendering is due to the definition shown above or it's an added feature

Hi Ante! Looks great! I'm trying to reach the yoshimura pattern developwd into a semi-arc-system. Could you send me a bigger image of the grasshopper definition? I can't read this one is too small.

Hi Wieland, the spatial definition of the origami pattern is based on a rhino element which constitutes the basic hull definition. It is one spiralling face from which a uv-grid is developed as needed in element density. From this grid I grab the uv-points and start re-arranging the initial sequence and tree data structure of given point lists as needed for developing series of 3-point-faces. The depth of the folding is constrained by the curvature of the given rhino definition and the density of the ditributed elements. More elements meaning lessening the depth of folding. If it were a classical flat square then it would just show a flat pattern which would only then develop its spatial qualities when bending the square with rhino operations. So, the rhino base definition also defines differentiation of elements. Constant curvature means same element dimensions. Every change of curvature results in different element dimensions. The hull is created manually, the folding pattern is scripted as can be seen above. Hope this helps your questions. Greetings from Frankfurt, Ante
