Fluxus is a rapid prototyping, livecoding and playing / learning environment for 3D graphics, sound and games. Extends PLT Scheme with graphical commands and can be used within its own livecoding environment or from within the DrScheme IDE. Builds for Linux (and sometimes OSX), and released under the GPL license.

Fluxus reads live audio, midi or OSC network messages which can be used as a source of animation data for realtime performances or installations. Keyboard or mouse input can also be read for games development, and a physics engine is included for realtime simulations of rigid body dynamics.

The built in scheme code editor runs on top of the renderer (see screenshots), which means you can edit the scripts while they are running. As well as making live coding possible, it’s also gives you a very fast feedback way of experimenting or learning about graphics and animation. The core graphics and synthesis engine is written in C++ for speed, and it’s high level language is PLT Scheme, chosen for creative flexibility.

Tutorial Movies: There are a series of tutorial livecoding movies, to give you some ideas about livecoding strategies using Scheme and fluxus. See the fluxus secrets page.
