HELP PLEASE! Inflatable developable structures via kangaroo

[phill.valsamos (Phillip Valsamos)]

I have a project at university where I will make an inflatable structure for any random shape (a shape like a random curve with a random hole in it). I have made this gh file where I take the two curves as input with kangaroo2 and inflate the surface. This gives me an open mesh which, of course, is not single curvature. How can I divide this mesh into single curvature strips so that I can unroll it and make a mockup. Ideally I would like it to look like the panels in Kai Zhang’s work, Kai Zhang - Inflatable Patterner

I just want to rebuilt this mesh, and create a new mesh from single-curvature stripes that has about the “shape” of the first mesh. (nearest to the first one)

This might be relevant. I think you need a quad mesh but kangaroo can do this sort of thing…

Kai Zhang has published a detailed blog post on how they produce and unroll theses topologies. It’s a very informative read!

PLEASE HELP ! Medial Axis Mesh Generation for Inflatable Structure

All the lines are ordered and put on a datatree. I already show you a way to extract the contours, not the best way, better with Path Mapper Then just do that [image]

thanks, i already read it but couldn’t understand exactly how he used c# to make the panels

There are many ways to make pieces from a mesh

Mesh clustering

[ba8688d3781e6455757789ec70ab5d8f16804698_2_1000x1000] Following the question of Gijs here a short explanation of my mesh clustering. A shape (disk here) is first triangulated with mesh machine, [image] Some random lines are draw on the shape [image] Points on lines are used to get index of mesh faces that are closes to the points. These index in a Datatree are then used as the seed to cluster the mesh [image] Contour of the cluster mesh is extracted as a polyline [image] Polyline …

Fern Lamp project

First virtual light for my new lamp design, some (many!) inspirations from @nervous.system with their Puzzle Cell Lamp but the generation of parts is made with my mesh clustering tool and the holes are done using my Fern Spores generator. Also I don’t know if I will make it in metal and/or wood. Here in France metal is quite the same price as birch plywood.

Pipe strips

Since the thickened curve meshes are all quads, with all even valence vertices, they can be sorted by direction and turned into strips [image]

then you have to flatten, also make the marks, the connections …

require quite some work.

thanks a lot for your suggestions, im gonna check them out!!
