Processing is a graphics library and integrated development environment (IDE) built for the electronic arts, new media art, and visual design communities with the purpose of teaching non-programmers the fundamentals of computer programming in a visual context. It is free and open-source software released under a GNU General Public License (GPL) and a GNU Lesser General Public License (LGPL).
Processing uses the Java programming language, with added simplifications such as added classes and aliased mathematical functions and operations. It also provides a graphical user interface to simplify the compiling and executing stage.
The Processing language and IDE are the precursor to other projects including Arduino and Wiring.
