The breve Simulation Environment http://www.spiderland.org/breve release _VERSION_ - _DATE_ command line version for Mac OS X, Linux and Windows [email protected] -= INTRODUCTION =- breve is a simulation environment which allows users to define the behaviors and interactions of different types of agents in a simulated 3D world and observe the emergent behaviors. breve is conceptually similar to packages such as Swarm and StarLogo, but simulates objects in a continuous 3D world with continuous time. breve thus allows simulation involving realistic collision detection and physics. Agent behaviors are written in a simple object oriented language called "steve". Users define an agent's behavior by specifying how the agent interacts with the world at each timestep and how the agent interacts when it collides with other agents. breve includes full collision detection and physical simulation of rigid bodies. See the Walker and Gravity demo simulations for examples. For more detailed information about the breve environment, consult the documentation in the "docs" directory. -= GETTING STARTED =- NOTE FOR WINDOWS USERS: You'll need to download the GLUT library in order to run breve. One source for this is: http://www.xmission.com/~nate/glut.html The best way to get started with breve is to run some of the included demo simulations, which are found in the "demos" directory. More complete information on programming and running simulations with breve is available in the documentation, which is found in the "docs" directory. These are the directions to get started quickly with the command-line version of breve 2.4. 1) set the environment variable BREVE_CLASS_PATH to the full path of the included "lib/classes" directory. For example, using the bash shell under Linux or Mac OS X: export BREVE_CLASS_PATH=<path to breve>/lib/classes Under windows, this might be something like: set BREVE_CLASS_PATH=C:\<path to breve>\lib\classes 2) run breve with one of the demo files: breve <simulation file>. For example: ./bin/breve ./demos/Gatherers.tz Or under Windows: \BIN\BREVE.EXE DEMOS\GATHERERS.TZ 3) press space bar to toggle the simulation, <esc> to exit. Use the left mouse button to select objects and to rotate the simulation, left mouse button + shift to zoom the camera and the right mouse button to access the simulation menu (or contextual menus associated with individual objects). F1 steps forward the simulation a single step. For more information about what the simulations do and how they work, open up the demo files in any text editor and read the comments at the top of the file. -= FEEDBACK =- This software is provided with the hope that it will be useful--the only way for me to make the software more useful is to hear your feedback. You can send me mail directly at [email protected]. Please let me know how you use the software and how it could be improved. If you have any cool or useful simulations or classes that should be included with future releases, mail them as well.
