A Rust solar system visualization built with macroquad.

It simulates:

• The Sun, Mercury, Venus, Earth, Mars, Jupiter, and Saturn
• Elliptical planetary orbits
• A toggleable 2D and 3D view
• The asteroid belt between Mars and Jupiter
• The Kuiper belt beyond Saturn
• Labels for planets and major belts

From the project root:

cargo run

• Tab: toggle between 2D and 3D
• Up: increase simulation time scale by 10x
• Down: decrease simulation time scale by 10x
• Space: reset simulation time scale to 1x real time
• Esc: quit

• Click + drag: orbit the camera
• Two-finger scroll: zoom
• Left / Right: keyboard camera orbit fallback
• W / S: keyboard camera tilt fallback
• Q / E: keyboard zoom fallback

• Real-time-inspired orbital timing
• Elliptical orbit guides
• Planet trails
• Saturn ring rendering
• On-screen labels for planets, the asteroid belt, and the Kuiper belt

• src/main.rs: simulation and rendering code
• Cargo.toml: crate configuration

• The scale is intentionally adjusted for readability rather than strict physical size accuracy.
• The belts are stylized deterministic particle bands rather than individually simulated bodies.
• The app supports an internal screenshot capture mode for regenerating the checked-in PNGs: CAPTURE_SCREENSHOTS=1 cargo run
