A basic real-time 2D solar system simulator using C and X11. It simulates gravitational physics and renders celestial bodies using vector math.
- Basic gravitational physics (Newtonian)
- Real-time rendering with X11
- Logging with levels (DEBUG, INFO, WARN, ERROR)
- Keyboard input (
qto quit) - Modular structure (X11, physics, logging, vector math)
- X11 development libraries (
libx11-dev) - A C compiler like
gcc - Make
Install on Debian/Ubuntu:
sudo apt update
sudo apt install build-essential libx11-devmake
./solar_system
| Key | Type | Description |
|---|---|---|
| timestep | int | Time delta used for each simulation step |
| resolution | int | Resolution (width and height) of the window in pixels |
| gravity | float | Gravitational constant used in physics |
Each planet is defined with a unique number (e.g. planet0, planet1) and has the following properties:
| Key | Type | Description |
|---|---|---|
| mass | float | Mass of the planet |
| pos | float,float,float | Initial position (x, y, z) |
| mom | float,float,float | Initial momentum (px, py, pz) |
| color | int,int,int,int | RGBA color (Red, Green, Blue, Alpha) |
| rad | float | Radius of the planet (visual scale) |
