Processing is an open source programming language and environment for people who want to create images, animations, and interactions.
It has the objective of teaching the fundamentals of computer programming in a visual context, and to serve as the foundation for electronic sketchbooks.
Processing is used by students, artists, designers, researchers, and hobbyists for learning, prototyping, and production.
Key Features
- Sketchbook, a minimal alternative to an integrated development environment (IDE) for organizing projects.
- Interactive programs using 2D, 3D or PDF output.
- OpenGL integration for accelerated 3D.
- Projects run online or as double-clickable applications.
- Over 100 libraries extend the software into sound, video, computer vision, and more.
- Good documentation.
