# Origami 02

###### Figure 01: Origami for 9 cells’ surface.

This is my second attempt for modelling the origami structures. a pattern of carefully folded faces to form a complex surfaces. Its known for its Japanese Arts origin. Now it become as one of the most desired architecture forming techniques. That because of its beautiful appearance and athetical effects on lights and shades.

We use computational now to arbitrary define the folding logics. simple mathematical operations to drive the folding mechanism. a series of surfaces rotaations around their folds axeces. in these operations, the surfaces are arranged to be dislocated and reformed to take the new fold settings, that include changing on its planarity, direction, rotation and original position. The process of Origamic folding is characterised by the two faces of folds, the positive and the negative. Usually, its sampled by drafting the folds edges in two different colors. the folds lines sometimes cut through the whole surface, sometimes it folds in small partiions intersect carefully in well-known patterns.

In the experiment, we used Kangaroo, the Grasshopper plugin, by Daniel Piker. In a previous attempt, I tried to use the first version of the physics engine. It was simple, but the level of performance on on the second version is impressive. so I had my second attempt. unfortunately, the Origami doesnt exist anymore, so I decided to try my own approach using the hinge tool. The new tool work fine in simple surfaces, however it require a bit more of efforts to run it on complex surfaces with multiple faces. So I built an algorithm which can catch the folds, and subsequently tries to set their corresponding hings and thier rotation direction and settling angles.

The process was a bit tricky, because it require a complex data structuring for the disconnected elements. The problem lays on the complexity of directing the planes of folds together with the folds two surfaces. its a kind of topological level of relationships where I needed to connect ligitamate folding edges with their adjacent surfaces. The process works on two directions and it requires multiple level of data trees. that because of the origami two folds directions.
