aframe-nbody-component

n-body simulation

A n-body system for A-Frame. Depends on aframe-physics-system

Use this system if you want to do a simulation of celestial bodies. Only use it if you really feel like tweaking a lot of values. This n-body system only does a direct gravitational n-body simulation. Does not take relativity into consideration. There are no calculation optimizations. Barnes–Hut simulation coming in the future.
