Looks nice - Is it actually rigid foldable ?

Well, if it was it would have developed into a semi-arc-system

nice job!

Hi Ante, looks really great. Congratulation! Did you achieve this without custom components or scripting? Can you explain a bit more how you definition works? Greetings from Munich, Wieland

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

Can you Share the definition ? 

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.
