Agenda

On day 4 we will continue to work on creating an image using Processing.

Specifically, we will use procedural abstraction to avoid repeated code when drawing similar or identical elements in the image.

Get ready

First, continue working on the Processing program you started in Lab 1, so that you have a relatively complete rendering of your graph paper sketch.

Next, think about

Whether there are elements in your image that are repeated exactly or with some kind of variation
Whether you could add some kind of repeated element to your image

Annotate your graph paper sketch to indicate repeated elements. Then, please read the write-up for Lab 2, where we will explore ways of concisely expressing repetition in a Processing program. Don’t worry if you don’t understand everything completely; we would just like you to have a sense of what you will be trying to accomplish in class.
