Reaction Diffusion – Python in GH

n this 4 day intermediate level workshop of Python in Rhino Grasshopper you’ll learn the fundamentals of scripting logic, from strings, operators, conditional statements to recursive functions along with classes and how to implement Python scripting for recursive functions into GH components. The workshop is organized in the course of 2 weekends, in order to allow students to comprehend the information in-between. The course doesn’t require you to know Python but it expects you to have the interest to reach a higher-than-beginner level during the 4 days duration. Rhino and Grasshopper3D knowledge is not required but welcome.

The course investigates 2D and 3D patterns that arise from reaction diffusion mathematical models, utilizing python in grasshopper to control the rules, densities and concentrations.

Method of teaching Python

The course will be taught through a series of Python components implemented in Grasshopper and their equivalent design outcomes.

Random stepper

Koch Snowflake

Circles Fitness into boundary curves

Diagrid Panels

Cushion Panels

Python Target Audience

This course is for designers, architects, interior and industrial designers and of course code enthusiasts who want to efficiently learn programming the features of the ghPython component and to acquire the ability of producing custom-based code components in Rhino Grasshopper for recursion requirements and enhanced flexibility.

Pre-requisites

Requires genuine interest to learn programming and desire for long hours of debugging. Previous experience with Python , Rhinoceros and Grasshopper interface helpful but not required.
All students are advised to bring their own laptop with already installed:

• Rhino 5.0  https://www.rhino3d.com/download/rhino/5/latest
• Grasshopper  http://www.rhino3d.com/download/grasshopper/1.0/wip
• GH Python component  http://www.food4rhino.com/project/ghpython?etx

In case you don’t have a Laptop please inform us atleast 1 week ahead of the workshop !
