Gravity

Building

To get started, clone this repository with all the submodules:

git clone --recurse-submodules https://github.com/f01zy/Gravity gravity && cd gravity

If you have NixOS then run the nix-shell to load wayland, X11 and OpenGL dependencies:

nix-shell

And now build the project:

mkdir build && cd build
cmake ..
cmake --build .

Usage

To launch the simulation with a custom body, pass the initial parameters as command-line arguments:

./gravity <x y z> <vx vy vz> <mass> <radius> ...

• x, y, z - Initial position coordinates (float).
• vx, vy, vz - Initial velocity vector (float).
• mass - Object mass (double, > 0).
• radius - Physical radius of the body (double, > 0).

For example, a scene with Earth and the Moon:

./Debug/gravity 0.0 0.0 0.0 0.0 0.0 0.0 5.972e24 6371000 0.0 0.0 384400000.0 1018.0 0.0 0.0 7.35e22 1737500
