A stunning, high-performance 3D Solar System Simulator. This project combines beautiful 3D graphics with realistic physics simulation. Features include interactive orbit controls, accurate gravity simulation via WebAssembly, gesture-based hand controls, and procedurally generated stars for an authentic stellar backdrop.
The simulator accurately renders all planets with procedurally generated textures, moons, and orbital mechanics. Physics calculations run on a Rust-based WebAssembly engine for blazing-fast performance without sacrificing visual fidelity.
