This is a gravity simulation using the runge kutter integration method.
To start a new simulation, change path in cnf.py to where you want your simulations to be stored, {} is a placeholder for the simulation id. (WARNING: SIMULATION FILES CAN GET VERY BIG)
Then you can run the simulation using simulate.py.
To render the simulation, run render.pyand enter the path of the simulation.
To create an own simulation environment, change environment.py to what you want it to be. X (shape=[?, 2]) is the array for the positions, V (shape=[?, 2]) is the array for the velocities, M (shape=[?, 2]) is the array for the masses of the particles, COLOR (shape=[?, 3]) is the array for the colors.
cnf.pyhas all the settings for simulating the environment.
cnfrender.py stores the settings for rendering a simulation.
There are 2 algorithms implemented for the simulation at the moment, the standard bruteforce algorithm and the barnes-hut-algorithm. The bruteforce algorithm is faster in most cases, to use it set use_barnes_hut in cnf.py to False. To use the barnes-hut algorithm, set it to true.
