toxiclibs is an independent, modular open source

Open source

The term open source describes practices in production and development that promote access to the end product's source materials. Some consider open source a philosophy, others consider it a pragmatic methodology...

 library collection for Java

Java (programming language)

Java is a programming language originally developed by James Gosling at Sun Microsystems and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities...

 and Processing

Processing (programming language)

Processing is an open source programming language and integrated development environment built for the electronic arts and visual design communities with the purpose of teaching the basics of computer programming in a visual context, and to serve as the foundation for electronic sketchbooks...

, released under the LGPL. In constant development since January 2007, currently the library consist of over 130 different classes, organized into 6 active packages. Each package is focused at specific computational design tasks. The classes are however purposefully kept fairly generic in order to maximize re-use in different contexts ranging from generative design, animation, interaction & interface design, data visualization to architecture and digital fabrication, use as teaching tool and more.

The libraries have been designed to have no further dependencies in order to maximize reuse and flexibility. Even though these libraries have been mainly developed for use in Processing

 related projects, there is no explicit dependency on the monolithic PApplet or any other classes of the Processing toolkit. This is intentional & should be considered as a feature.
