7. Computational Couture

This week we worked with the software Rhino and especially with Grasshopper, we learnt how to create computational patterns and how to play with algorithmic parameters.

Inspiration

There are a few projects using Grasshopper in the design process. It's amazing how faces and bodies become a landscape to play with.

To make a circle grid : Circle grid

To put the pattern in a shape : Pattern in a shape

Grasshopper

Grasshopper generate algorithms than can regulate a shape. We can draw the pattern directly on Grasshopper.

A few functions I used :

  • set one point -> connect 2 components
  • bake -> construct in Rhino
  • disable -> make a function temporary not working (avoid long waiting time)
  • enable -> make a function working

Hexagonal grid

To make a grid, go to vector and then hexagonal grid. This is how to play with the size of the grid :

Scaled grid

This is the code to make a scaled hexagonal grid following 2 lines. The size of the hexagons will depend on the distance there are from the 2 lines : the more distant, the smaller are their areas.

scale

Circle scaled grid

I followed this tutorial to make a circle grid. Then, I made the size of the circles from the grid depends on the distance from a circle.

This is the code :

circle

GH file is here and STL file is here.

What it looks like step by step :

A visual example : chose the size of the circles

Triangular scaled grid

The code :

In Rhino : triangle

GH file is here and STL file is here.

Adding a grid in a shape

This tutorial helps me.

The code :

In Rhino :
