# Orbital Mechanics Simulation

A 3D orbital mechanics simulation using a 2-body gravitational model with sphere of influence (SOI) transitions.

## Features

- 2-body gravitational physics with SOI transitions
- Configurable star systems via toml files
- Solar system and binary star example configurations

## Getting Started

### Cloning the Project

```bash
git clone --recursive https://github.com/yourusername/claudes_game.git
cd claudes_game
git submodule update --init --recursive  # If already cloned without --recursive
```

### Dependencies (Debian 13)

```bash
sudo apt update
sudo apt install -y build-essential g++ make libx11-dev libxcursor-dev \
    libxrandr-dev libxinerama-dev libxi-dev libgl1-mesa-dev libglu1-mesa-dev
```

### Building

```bash
make              # Build raylib (first time) and compile sources
make rebuild      # Clean and rebuild
make clean-all    # Clean everything including raylib
```

## Running

```bash
./orbit_sim       # Run with the default solar system configuration
./orbit_sim configs/example_binary_star.toml    # Run with a custom configuration file:
```

## Documentation

- **[Technical Reference](docs/implementation_plan.md)** - Data structures and module overview
- **[Detailed Architecture](docs/verbose_project_overview.md)** - Complete implementation details and data flow

## Testing

```bash
make test              # Run full automated test suite
```

The test suite validates:
- Orbital period accuracy (Earth, Mars)
- Energy conservation (RK4 integration)
- SOI transitions and multi-body interactions
- Eccentric orbit behavior (comets, parabolic, hyperbolic)

All tests use Catch2 framework with configurable time steps and durations.
