- Add raygui as git submodule in ext/raygui/
- Update Makefile to include raygui headers
- Extend RenderState with UI fields (selected_body_index, show_body_list, show_body_info)
- Implement render_body_list_ui() for scrollable body list panel
- Implement render_body_info_ui() for detailed body information panel
- Add 'B' key toggle for body list panel
- Integrate UI rendering into main render loop
- Initialize UI state in main()
- Add tomlc17 library as git submodule
- Update Makefile to build tomlc17.c with C compiler
- Replace config_loader.cpp with TOML-based implementation
- Add helper functions for parsing TOML tables (position, color)
- Convert all 5 config files from .txt to .toml format:
* configs/solar_system.toml - full solar system with planets and moons
* configs/example_binary_star.toml - binary star system
* configs/test_simple.toml - various orbit types for testing
* tests/configs/earth_circular.toml - Earth orbit test
* tests/configs/mars_circular.toml - Mars orbit test
- Update all test files to reference .toml extensions
- Remove old .txt config files (maintain compatibility)
- Support both INT64 and FP64 TOML values (tomlc17 type flexibility)
- All automated tests pass with new TOML format
Claude
Orbital mechanics simulation with 2-body physics and SOI transitions.
Core Features:
- 2-body gravitational physics with sphere of influence transitions
- Real-time 3D visualization using raylib
- Configurable star systems via text files
- Interactive controls (camera, pause, speed)
Technical Implementation:
- C-style C++ (structs and functions, no classes)
- Modular architecture (physics, bodies, config loader, renderer)
- Euler integration for orbital mechanics
- SOI detection using Hill sphere approximation
Configuration System:
- Solar system with realistic data (Sun, 8 planets, 5 major moons)
- Binary star system example
- Easy to create custom systems via simple text format
