@kevroy314 I simply applied gravity equation, which proportional to particle masses and inversely proportional to the squared distance between particles. To acceleration computation I used ht eBarnes Hut which approximates a cluster of particles located far enough with a single particle which mass is the sum of the cluster mass and the position is the barycenter of the cluster.

@TheJesseLenney No I did'nt try to simulate in astronomical scale. The reason is that values are far too big, and I did'nt want to do some trick in scale conversion. So I decided to normalize eveyrthing between 0 and 1. It's quiet generic. It can be multiplied by the factor you want, to get it at universe scale.

It looks so 3d even though I think its 2d wow mind bending.

i ur fan..of urs...
am new to creating simulation..
can u help me..which program to generate should i use data.and what should i use to simulate with?
u help will help me alot

[kevroy]

what method did you use? i'm just starting to get into n-body simulating and yours looks really nice. how fast is that computing? how did you end up handling the collision singularity?

[loggonable]

is it just me or does this look almost like atomic orbitals?
