Programming for Visual Artists

Aalto University

Functions and Recursion

Use this session to work with reusable code, recursive drawing, spirals, and noise.

Before class

Read and run

Skim the slides, then open one browser sketch or source file so the vocabulary is already familiar.

During class

Change one thing

Use the Lab or Processing source to test one visible change while we discuss the code together.

After class

Keep the experiment

Save one version, write down what changed, and use it as possible material for your study work.

Start in the Browser

Run the recursive tree to see how one function can call itself.

Edit recursive tree in the Lab View recursive tree

Compare with Processing

Use these source files to continue locally.
