#91 | arc15 – Phyllotaxis column

Hi guys!

A short post about how to bake and render a 3D parametric model on Grasshopper/Rhinoceros.

So I’ve learned today what you need to do to make a render, but first of all, let’s explain how Grasshopper I have proceeded (I’ll explain everything a bit more in details later since I don’t have a lot of time. Using nodes and connectors, it is possible to make a parametric model. For this project, I used three steps to make an inspired phyllotaxis structure column.
The first one is to raise the circles into a cylinder and to make a rough shape of the object. I wanted the top circle of the column to be larger than the bottom, so I needed to scale it depending on what I wanted. For the second step, I needed to do an armature, so I had to create one part of the structure and duplicate it on the object with a parametric angle. Then, the third step is covering the entire column with a mirrored placement of the armature line. To bake the armature, just select all the nodes and right-click and “bake”. Then, you just need to render on Rhinoceros.

I know, it is not really a detailing tutorial thing, but it is because I am still not convinced of what I am doing. I will explain everything when it will be complete and if I am sure it will work.

What did I learn?

  • Nodes and connectors use
  • Number slider
  • Surface function, loft, and mirror
  • xyz units, and moving vectors
  • Affecting a point to a “point” node
  • Using a panel
