aframe-nbody-component
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.

API
| Property | Description | Default Value | | -------- | ----------- | ------------- | | g | Gravitational constant of the universe | |
Installation
Note you have to turn off gravity from the aframe-physics-system for this to work.
