breve

Breve is a free, GPL software package that enables users to build 3D simulations of decentralized systems and artificial life. Users can define the behaviors of multi-agent systems in a 3D world and observe how they interact. Breve includes 3D articulated body physical simulation with collision detection and response and an OpenGL display engine, so one can simulate and visualize semi-realistic creatures and worlds. Breve simulations are written in an easy-to-use language called steve. The language is object-oriented and borrows many features from languages such as C, Perl and Objective-C. Breve also includes full support for writing simulations in Python. Breve features an extensible plugin architecture that allows one to write plugins and interact with pre-existing code and projects and has built-in support for the Push programming language for evolutionary computation. Plugins have been written in Breve to generate MIDI music, download web pages and interact with a Lisp environment. A simple Braitenberg simulation.
