bevy-nbody

Experiments with a basic n-body simulation in 3D to checkout Bevy.

In particular, pretty cool ephemerides data from JPL Horizons allowing you to get initial conditions to simulate the Solar System. Distances between objects are to-scale (0.1 AU/unit). Radiuses of planets as well (10^-4 km/unit) but not the Sun. Note that therefore radiuses and distances use a different scale.

N-body 3D simulation with Bevy

Several `--startup` options:
* solar: planets of the Solar System - and Pluto :'( - with data from JPL Horizons as-of 2021-04-18.
* figure8: stable figure-8 three-body solution
* random: generates random bodies around a large star

Mouse controls: 
* right-click & drag to orbit the camera 
* scroll to zoom

Options:
  --startup         startup system [solar (default)|figure8|random]
  --speed           speed of the simulation [default: 1.0x]
  -d, --debug       enable diagnostics in the console
  --help            display usage information
