A note on this workshop

• The goal of the workshop is to produce a 3D visualization of a toy dataset of Twitter status
• The main way I will test your understanding of the material covered so far is to ask you to tweak the code examples I give in some way to change the output
• If you're stuck - don't worry! The workshop is designed to give you a taste of what's possible with Processing and to encourage you to follow up if you find it interesting.

Exercise 0

• Download the code examples for this workshop from https://github.com/eamonnbell/dcip-workshop/archive/master.zip
• Unzip this file to somewhere handy and navigate to the ex0 subfolder.
• Double-click on ex0.pde to open the Processing sketch.

A Processing sketch is not just a single file. It's:

• a main sketch file: SKETCH_NAME.pde
• other .pde files defining custom classes
• other .java files and data files
• ...all inside a folder that has to be called SKETCH_NAME

You can think of Processing as a subset of Java. So if you know Java, you know most Processing syntax. If you don't, no worries!

Question: Before you run the ex0 sketch, what do you think it does?

Question: Run the ex0 sketch with the menu (or Ctrl-R). What does it do?
