Introduction

Welcome to Grasshopper!

For designers who are exploring new shapes using generative algorithms, Grasshopper® is a graphical algorithm editor that takes advantage of Rhino‘s existing tools. Grasshopper offers new ways to expand and control the 3D design and modeling processes, including automating repetitive processes, generating geometry through mathematical functions, quickly making changes to complex models, and creating complex forms through repetitions of simple geometry. Grasshopper requires no prior programming or scripting knowledge, and allows designers a high degree of flexibility in creating both simple and complex forms.

The combination of Rhinoceros with the Grasshopper platform makes parametrizing structures via a clear, visual programming interface possible. Parametric objects in Grasshopper are generated through graphic programming. These objects can be modified and adapted within Grasshopper simultaneously affecting the corresponding object in the Rhino modelling interface.

This tutorial should give you an overview about Grasshopper itself as well as the navigation and basic components. Further it shows how the plugin connects with Rhino and some important shortcuts for a smoother usage.
