#81 – Grasshopper and parametric models

Hi everyone.
Today, let’s talk about a new 3D software called Rhinoceros and Grasshopper.

So, Rhinoceros is a 3D software but what is really interesting is Grasshopper which is a programming software that can be used for the parametric modelization. The great thing about Rhinoceros and Grasshopper is that you can see the direct result of what you are doing in the parameters and it is really easy to understand how everything works. If we compare Rhinoceros and Blender both are interesting for different reasons: the first one for an easy understand used of the volumes and the shape, you don’t need to go in python and understand the language to make some programming. The object-based programming is easier to understand, however, the render is more beautiful on Blender. What is also interesting is the “time” parameter on Grasshopper that can modify the model based on the local time of the computer (I guess it is also possible with Blender/Python but It’s interesting how it’s more intuitive on Rhinoceros).

Parametric models can be used for different purpose: to show how a model can change based on variables (light, height, time, etc). It is also interesting to generate a series of different models based on the parameters: it is a tool to understand object behaviors.
I’ve not done a lot of researches on the software since I’m learning the basics use of the software for now. I’ll show you what it looks like later.

What did I learn?

  • How to make basic shapes and volume on Grasshopper.
  • How to implant time parameter on a shape.
  • Find a way to make Phyllotaxis formula on a 3d model.
