Processing is a programming language about making visual art. Processing is geared towards making interactive drawings with code. It works on Android, iOS, GNU/Linux, Mac, and Windows. Drawings can be generated from mouse movements, music frequencies, GPIO inputs, or web apis. Processing is one of the easiest languages to learn. Processing uses java syntax by default. You can also use javascript live on webpages through p5.js. Python syntax can also be used if enabled.

Installing Processing on GNU/Linux

Installing Processing is very simple on most operating systems, yet people have trouble with the instructions for installing on GNU/Linux distributions. Here are scripts and instructions to easily install Processing on GNU/Linux systems.

64 bit GNU/Linux

Open a terminal, run these two commands:

wget https://raw.githubusercontent.com/TechnologyClassroom/Processing/master/install-linux64.sh
sudo sh install-linux64.sh

32 bit GNU/Linux

Open a terminal, run these two commands:

wget https://raw.githubusercontent.com/TechnologyClassroom/Processing/master/install-linux32.sh
sudo sh install-linux32.sh

Raspberry Pi and ARM based GNU/Linux

Open a terminal, run these two commands:

wget https://processing.org/download/install-arm.sh
sudo sh install-arm.sh

Scripts

These are scripts I have made or modified using Processing:

Screenshot

Generative art using randomly moving triangles of random sizes. These triangles have a calming and mesmerizing effect on the viewer. As this script continues, the result becomes more unique and beautiful. Run for an hour to multiple days. Hold 's' to save images.

Screenshot

JitterRotate is an experiment with semantic errors. Generative art using randomly moving triangles of random sizes, colors, rotation, and transparency. This sketch only takes about 30 seconds to peak. Hold 's' to save images.

Screenshot

Draw with squares, ellipses, and triangles. Shapes have random fill color, stroke color, stroke width, and size. WARNING: Contains flashing lights. Hold 's' to save images.

Linting

If you would like to run checks on your processing code, you can install Github's Atom text editor with the linting-processing extension.
