This tool allows you to simulate a fictional particle physics. Each particle has a location (
y) and a weight, which can be positive (attractive), negative (repulsive), or zero. The fundamental force acts upon the world in discrete moments of time. The force a particle exerts is proportional to its weight, inversely proportional to the distance between it and its object, and irrespective of the weight of its object:
force of A upon B = (weight of A) / (distance between A and B)
Units are defined so that in
1 moment, a particle of weight
1 will cause a particle
1 unit away to move
1 unit towards it (see the
To input particles into the editing buffer, add one line for each particle, expressed as the
x y weight values separated by spaces.
