== From Code to Curves ==

[[File:Beetleblocks_bsp.png|thumb|left|3D turtle graphics with [http://scratch-dach.info/wiki/Beetle_Blocks Beetleblox]]]

<br style="clear:both;">

=== 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 ==

{{#ev:youtube|0x7rg9TpHSo|400|left|Evan Roth: Introducing Mozilla Mark Up|frame}}

<br style="clear:both;">

=== 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 ==

{{#ev:youtube|2xvczE4-5hs|400|left|Martin Schneider: Fractal Image Embroidery in Motion |frame}}

<br style="clear:both;">

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