2d gas simulation interactive. Program starts with window of parameters: box sizes masses velocities etc. Then simulation starts. It is possible to move balls with mouse clicking the ball. Clicked ball will get velocity of pointer. Also other controls: accelerate, random velocities etc. It is possible to return to window of parameters. Simulation window is elastic and it is possible to stretch it to fill all screen size. See move of it here:
Unzip and run rum_me.m in Matlab.
Thanks to Kotkin G. and Cherkasskiy V. for initial not intaractive simple code.
thanks a lot
You are the one.....
Goog work. I've been working in a 2D/3D vectorized version of "billiards", with balls having 2 collisions at the same time and falling (or not) by gravity, but your interactive simulation is better. The only advantage could have my version is that can run with hundreds of particles and not appreciably slowing down
