Meandering Code

From Code to Curves

3D turtle graphics with Beetleblox

About

We will learn how to program turtles, and how to create abstract line drawings from code

Goals

Learn to use string processing functions
Learn to write a turtle code interpreter
Basics of Object Oriented Programming (OOP)

Processing Curves

Evan Roth: Introducing Mozilla Mark Up

About

We will get to know interfaces for creating curves, learn how to store them, and how to output them

Goals

Learn how to use Libraries in Processing
Learn how to read and write strings to files
File Formats Graffiti (GML) and Motion Capture (BVH)
Using input devices such as a Graphic Tablet, Tracking-System, etc. to create curves
Use Processing to output curves in the visual domain
Use Spacial Synthesizers such as Zirkonium and Iannix to output curves in the auditory domain

Transforming Curves

Martin Schneider: Fractal Image Embroidery in Motion

About

In this lecture we will learn how to transform curves programatically.

Rewriting Curves — In the 1st part we learn how to create space filling curves and meanders with the help of rewriting systems.
Remapping Curves — In the 2nd part we take curves to higher dimension and learn how to map points on a line to the plane (and back).

Goals

Basics of Fractal Geometry
Learn to work with data structures, arrays and vectors
Learn how to design Lindenmayer-Systems
Learn how to design Remapping-Systems

Literature

There is a most excellent book, titled Brain-Filling Curves: A Fractal Bestiary by Jeffrey Ventrella.
Don't miss it. It's the best and most exciting book on spacefilling curves out there!
