2. Outline Motivating Processing…What is Processing? Sample Program
Processing development environment (PDE)/ Main Processing interface

3. Motivating Processing
Focus is on multi-media and graphics
Simple to translate from ideas to “Visualization”, “interactive graphics”, “Animations”
Easy to use “zero-entry approach to coding”
Open source, abundant community contribution
Built-on top of Java
Can be exported to mobile application environment using Android mode
Can be exported to Web environment using Javascript mode
… many more

4. Sample Program: lets analyze this
void setup() { // initialization : executed once size(400,400); stroke(0); background(192,64,0); } void draw() { // repeated every time mouse is moved line(150,25,mouseX, mouseY);

5. Lets look at Processing Environment

6. Using processing: Page 9-16
Environment:
PDE is a simple text editor for writing code.
When programs are they open a new window called the display window.
Pieces of software written in Processing are called sketches.
There is console at the bottom of Processing environment that display output from println() and print() functions.
The toolbar buttons allow you run and stop programs, create a new sketch, open, save, and export.
There are other buttons for file (operations), Edit (operations), Sketch (start and stop), Tools (for formatting etc.), Help (reference files)
Lets work on the samples given in these pages.

7. Summary We had a gentle introduction to Processing Environment
Your assignment this week:
Read pages 9-16
Download Processing 2.1 or above version from processing.org and install it; if you have difficulty please go to next week’s lab/recitation in Bell 340 to get help on installation
Try the examples given in those pages. Try something on your own. Understand the various features of the PDE.
No recitation/lab this week(1/26-1/30)
Do go to your recitation next week. All recitations are held in 340 Bell.
