A physics-based 3D Solar System simulation built from scratch using Java and JavaFX. This project combines a custom N-Body physics engine with accurate orbital mechanics and a dynamic "God Mode" sandbox to create a professional and interactive space environment.
- N-Body Physics Engine: A custom-coded engine that calculates real-time gravitational forces between all objects.
- Mixed Kinematic Model:
- Planets: Fully dynamic gravity-based movement.
- Moons: Parametric deterministic orbits to ensure infinite stability around moving hosts, eliminating numerical drift.
- God Mode (Creator Panel): A slide-out HUD that allows the real-time injection of custom celestial bodies with adjustable mass, distance, and velocity.
- Quick Save/Load System: Full state serialization to disk. Save your orbital configuration and resume it at any time.
- Realistic Visuals:
- Unified Deep-Space HUD design (NASA-inspired) with a minimalist, non-intrusive aesthetic.
- Procedurally generated Saturn's rings and immersive skybox.
- Real-time orbit trails to visualize complex gravitational interactions.
- Collision Physics: Conservation of momentum applied when bodies collide and merge.
