Did you ever wonder, how they do the simulation of all that snow, rain, dust, smoke, and fire in modern computer games? How they model bullets, ropes, curtains and solar systems?
With this Matlab particle system toolbox you can easily create particles, attractions, and springs in a particle system environment with gravity and drag and graphically simulate their interactions with just a few lines of code. Run one of the 12 demos and study the detailed documentation.
Have fun ...
