algorithmic modeling for Rhino
Hi, I am trying to make this in plain GH. Got stuck. Moving and rotating a point around in space... Flipping diagonal creases (from left or from right with a toggle) adjusting the lenghth of each triangle individually and bending at every crease, trying to keep the width of the „paper” stripe.
The definition is getting a bit too complex for me and its hard to keep the toggles under control :)
Can you advise and show me a simple solution please ? Perhaps one that I could add more triangles with a slider instead of copying the individual definitions... I am not a programmer nor a mathematician, but it seems to me there must be some easier solution, perhaps with matrix operations (I have no experience with that yet)?
Hope somebody could help me.
Thank you.

i am not sure wht exactly is your plan.
Do you want to define all your angles of folding before moving - or recreate a certain geometry with your stripe?
Hi
well to recreate surfaces - that will be difficult.
if you define the rotating axis first, the result can be this.
I made this project with students in Paris.
You can also look at the work from a group called archiwaste.
You have to be more exact in what you want - otherwise the stripe will drive you crazy!
:) yep my feelings exactly...
thank you for sharing with me, that's actually where I am aiming - at a practical realization in a large scale + love the use of paper/cardboard.
Thanks again.

Jiri,
I am glad that you liked the explodebreds site. I looked at your definition and have to confess to both admiration and terror at the number and arrangement of wires you show. I decided not to try to unpack this but to start from scratch to see what is possible. The first try had sliders controlling all the parameters. While quite flexible I found the lack of intent in outcome not satisfying. So working from your image I produced a definition that creates a pyramid from your strip. I think this could be modified to be more responsive to dimension of paper, etc. but wanted to get you the general idea. I am not sure this is what you are looking for but at least it provided a fun few hours.

Wow, that is amazing in its simplicity. Thank you for your insight Robin.

this may be a bit late, but thank you for this definition! i was stuck on a similar problem - i was stumped by the way the fold angles successively change the overall form of the strip. this has helped a lot - thanks again! :D
the math solve the problems
more complex origamis need more complex calculations
