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 example configurations

Getting Started

Cloning the Project

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)

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

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

Running

./orbit_sim       # Run with the default solar system configuration

Documentation

• Technical Reference - Data structures and module overview

Testing

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.
