What is breve?

breve is a free, open-source software package which makes it easy to build 3D simulations of multi-agent systems and artificial life. Using Python, or using a simple scripting language called steve, you can define the behaviors of agents in a 3D world and observe how they interact. breve includes physical simulation and collision detection so you can simulate realistic creatures, and an OpenGL display engine so you can visualize your simulated worlds.

breve is available for Mac OS X, Linux and Windows in the download section.

breve 2.7.2 now available for download [02/19/08]

breve 2.7.2 fixes a crash during startup on Mac OS X, issues with the breveIDE for Windows and Linux, and a problem deleting objects in Python simulations.

breve 2.7 adds some major new features, including:

  • Support for non-convex shapes.
  • Support for importing shapes from 3DS.
  • Improved support for writing simulations with Python.
  • Improved graphics and rendering.
A full list of changes in breve 2.7 is available here.

Write Your Own Simulations

breve simulations are written in the popular Python language, or in an easy-to-use language called steve, which is object-oriented and borrows many features from languages such as C, SmallTalk and Objective C. Regardless of which language is used, users without previous programming experience will find it easy to jump in. More information on both languages can be found in the documentation section.

Interface With Your Own Code

breve features an extensible plugin architecture which allows you to write your own plugins and interact with your own code. Writing plugins is simple and allows you to expand breve to work with existing projects. Plugins have been written in breve to generate MIDI music, download web pages, interact with a Lisp environment and interact with the "push" language. To develop your own plugins, you'll need to refer to the plugin documentation.
