Video tutorial: origami folding structure

In this Grasshopper Rhino tutorial you are going to learn parametric modeling of a folding roof structure. It uses origami folding technique and Kangaroo for physics modelling.The tutorial is available here

i have question
how can i add origami pattern on surface?

Hi Behnam,

You have to draw out your origami in flat, convert it to mesh, draw valley and mountain folds using lines, and then put it all through the same definition as I did (see link in the original post). Alternatively, you can also define your own folds on the surface with Kangaroo hinge forces. Simpler origamis can be modelled with simple rotation and mirroring technique, but it quickly gets very complex. Also, origami patterns cannot take any shape of the surface. It is usually better to model the surface from bottom up i.e. first making the pattern, applying forces and see what shape comes out.

It looks like the latest Kangaroo uses new tools for doing origami. Can you post a simple updated example?

By looks the latest Kangaroo has a ghuser file for origami that is similar to the definition (using Hinge forces) but packaged differently. I will post an update soon.
