New origami example

This example shows the use of the new user object for origami simulation.

As input you provide a flat mesh of the folding pattern, curves to assign as either mountain or valley folds, target angles, and folding amount, with 0 being flat and 1 being completely folded.

Ah, that's why - install 0.099 and this should work.

(Keeping 2.01 - you can have them installed side-by-side)

Well, now I have the timer control, but I still can't get it to run. I exchanged your angle panels with number sliders accordingly and then pressed play. Can you tell me, what I'm missing? It just remains flat.

Thanks already for your response!

Hello there,

i have tried this definition on a simple square mesh and Del curves. In case of true origami / paper folding the length of mesh edges before and after the simulation should remain constant isn't it? However, in my simulation i edge lengths of flat mesh and folded mesh are slightly different. Can you please help :-(?

Regards,

Hello Daniel,

i have used your definition for a simple rectangular mesh formed by Del triangulation method. I have one question, Since it is an origami, the length of mesh edges before and after the simulation should be constant is it not? However, in my definition there is a variance between the two lengths. Can you please help?

Thank You

Hi Daneil,

I use your definition and add string force to it because i want to make the folding surface into a cylinder shape.But the shape doesn't look like so round , so i want to add one more string force after the surface has already been folded, but it doesn't work, the error message is -solution exception.

Hi Daniel Piker,

Great Job actually!! I have tried to run this definition on my machine and it works！But I am experiencing some problems when I tried to apply my customized pattern onto this definition. As shown below, I created a Diamond pattern mesh in Rhino, and defined the mountain and valley lines onto the corresponding components, but the Kangaroo engine seems donot work currently.

I really appreciate if you could help me.

Or any one facing the same/ similar problem ? -- Thank you guys in advance!!

Use this (attached) definition instead. But I have a question for you: How do you create your own mesh like that? I must be being stupid here but I don't know. Guess I'm still new to Rhino.

Hi Alex,

Thanks very much for your quick replies!

How I created the mesh is to firstly crest basic polylines and then use MeshFromPolylines command in Rhino to translate the polylines into mesh. After that the basic mesh is mirrored and copied, finally I use Join command to join all the objects together.

And also I have tried your definition, but it still doesn't work on my mesh.

So I am thinking about if the Diamond mesh I created is not that perfect. Can you please have a check of my mesh pattern? I'd really appreciate if you could help me for this task. I have tried the MeshPatch command in Rhino to create mesh but it didn't work that well, so I gave up and utilized my own manner lol.

Thanks a lot,

I'm really no expert at all. The definition I gave you is from earlier in this thread hahaha. But you should post the new definition with your mesh so I can see what the error message is. Or someone else can see.

As attached are the definition and the mesh. I have provided those two in my original post lol.

Thanks guys who can help anyway.
