Paper-fold models in Rhino+Grasshopper, can you advise, please?

Hi everyone,

I would like create some grasshopper definitions of paper models that we are making by hand and to be able to change them in 3D (and compare the results) by changing the 2D geometry (the unfolded pattern). I think I would like to achieve something like the software Rigid Origami does, but using Rhino+Grasshopper instead.

Although being an architect myself I am a beginner in Grasshopper and therefore I would like to ask you for some advice on where to start, how to define the paper folding behavior in GH.

I am doing some research into paperfolding and make paper models with the students at the Brno University of Technology Faculty of architecture:

I found this website of Tomohiro Tachi very inspirational, especially this article:

I found some descriptions that I think are useful here (however I would like to be able to change the geometry in 2D-unfolded pattern instead):

I also liked one example (the outcome) made by Michele Calvano and left a message on his grasshopper3d.com page but he did not reply:

Could you please advice me?

Thank you.

I have been researching and experimenting a little bit however got stuck, could anyone please advise on simplification? Here is the discussion post:

Hi Jiri,

Sorry, when I said I managed to successfully make them, those origami's aren't the four point star but they're similar and I'm guessing that it's methods might be similar.

http://www.instructables.com/id/Holy-Grail-Project---Re-Usable-Coll... in this link the template is a diagrid that forms a compressible cylinder

http://www.ams.org/news/math-in-the-media/mmarc-09-2007-media the template in this link makes a cone (sort of, but they called it a pine cone), which seems to be closer to where the money's at.

But I'm still trying to figure out the template for the four point star. I have an idea of how it might look from plan, but to figure out the height that will make it fold inwards nicely. Each time I do it, the inward folds tend to expose itself. I'm pretty busy at the moment so I'm struggle to find time to work on this, though I will let you know if I've made any progress!

Hi, happened to stumble upon this website
http://explodebreps.wordpress.com/category/0-0-simple-operations/0-...
a couple of years ago. Maybe some of the examples could be interesting. For example:

The videos on Daniel Piker's blog are also inspiring.

Search for his name in this forum to for some discussions about rigid origami.

Those are very interesting links.

Thanks.

Jiri,

Great discussion! Thanks for getting in touch with me. Please reference this discussion for the overall idea: As of now, each crease pattern in my video has a custom definition to get it to work. I'm still developing a generic definition.

Tomohiro Tachi has also posted some videos on this web site so he is probably the best resource to contact on the topic.

I would be interested to hear more about your research and am available to assist if I'm able.

Hi Erick,

could you please have a look at this and tell me if there is a way to simplify it? Or perhaps share some of your development ideas? Here is the related discussion link: http://www.grasshopper3d.com/forum/topics/paper-stripe-bending-need

Thank you.

Thank you Fred,

I watched in amazement this video about a year ago and thanks for sharing. If you're interested I run a Facebook group on this topic Space and Light in Architecture, you can join in: https://www.facebook.com/groups/193285444029176/
