Learn PROCESSING-PY with Real Code Examples

Python syntax for creating visual sketches with Processing libraries.

Supports 2D and 3D graphics rendering.

Handles animations, user interaction, and event-driven programming.

Bridges creative coding concepts with Python programming.

Used for learning programming, generative art, and prototyping interactive visuals.

setup() - initializes the sketch

draw() - continuously renders frames

Shapes and colors - rect(), ellipse(), fill(), stroke()

Interaction - mousePressed, keyPressed, etc.

PVector - vector math for motion and physics

Sketch - the program defining visual output

setup() - runs once at start

draw() - continuously executes to animate

Events - functions triggered by input

PVector - represents points and vectors in 2D/3D space

sketch.pyde - main Python sketch file

data/ - assets like images, fonts, or sounds

libraries/ - optional Processing libraries

export/ - exported application or applet

docs/ - notes and resources

Create new Python sketch in Processing IDE

Define setup() for initial parameters

Write draw() for animations or visuals

Add event functions for interaction

Run sketch, iterate, and refine visuals

Beginner: drawing shapes and colors

Intermediate: animations and interactive sketches

Advanced: generative art with algorithms

Expert: integrating sound/video and physics

Architect: combining multiple Processing libraries for creative applications

Processing.py vs Processing Java: Python syntax vs native Java

Processing.py vs P5.js: Python desktop vs JavaScript web

Processing.py vs Pygame: simpler creative coding vs game-oriented

Processing.py vs OpenFrameworks: lightweight educational vs high-performance C++

Processing.py vs Unity: creative coding vs professional game development

2001 - Processing created by Reas and Fry

2005 - Processing IDE stabilized and widely adopted

2009 - Processing.py introduced as Python mode

2010s - Expanded library support and community examples

2015 - Processing.py tutorials and workshops widely available

2020s - Integration with Processing.js and P5.js

2025 - Processing.py remains actively used in education and creative coding

Sketch - the main program

setup() - initialization function

draw() - repeated rendering function

PVector - vector object for motion/position

Event functions - mousePressed, keyPressed, etc.
