Grasshopper allows designers to perform graphical, component-based algorithmic modeling in Rhino. Python extends this functionality, allowing you to create custom scripts for Grasshopper and perform more complex workflows by working directly with the Rhino API. This course introduces the Python programming language to designers who want to do more with Grasshopper. Learn the basics of Python, including variables, data types, conditionals, and loops, and discover how to import additional libraries to extend Grasshopper. Instructor and computational design expert Jeremy Graham then introduces workflows for lofting, sorting, and baking geometry in Grasshopper—using powerful and fast Python scripts that push the boundaries of this visual programming tool.

Topics include:
Python components
Accessing the Rhino API
Python programming basics
Importing modules and libraries
Grasshopper workflows
Evaluating surfaces
Creating and splitting surfaces
Transforming geometry
Baking geometry from Python into Rhino
Adding text objects
Exporting rendered frames for animation
