I made this presentation for an undergraduate-level class in programming language concepts. It might be useful for someone doing a similar assignment. More information on the Processing programming language is available at http://www.processing.org/

1. Processing

2. Origins
2001
Computer Graphic
MIT Media Lab Science Design
Aesthetics +
Computing Group
Statistics
Ben Fry & Casey Reas

3. Education
NYU ITP
UCLA Design | Media
Arts
Lincoln, NE Public
Schools

4. Commercial Applications
Motion Theory
Nature, NYT, Seed
HeHe
Apple

5. Processing Features
Programming
Language
Sketchbook
Runtime

6. The Language
Java-like
void setup() {
PFont font = loadFont(quot;myfont.vlwquot;);
Strong typing }
textFont(font,20);
Polymorphism void draw() {
text(quot;Hello World!quot;, 30,50);
}
Classical inheritance

7. The Graphics API
void drawCircle(int x, int radius, int level)
{
float tt = 126 * level/4.0;
fill(tt);
ellipse(x, 100, radius*2, radius*2);
Procedural if(level > 1) {
level = level - 1;
drawCircle(x - radius/2, radius/2, level);
drawCircle(x + radius/2, radius/2, level);
Global scope }
}
Graphics generation
Image processing

8. Third-Party Libraries
Video DXF
Network Audio
PDF JavaScript
Hardware interfacing Databases
OpenGL …

9. Limitations
1.0 as of November
Small user base
Limited scope
Small body of literature
Java

10. Demonstration
