What is bungee?

Gaussian Cloud Bungee Simulator is a browser-based physics game that lets you bungee jump inside 3D scenes built from a technique called 3D Gaussian Splatting, which turns static 3D scans into environments you can move through. It runs in the browser using Three.js and WebGL for rendering, with a library called gaussian-splats-3d handling the point cloud graphics. What sets this project apart is that you are not stuck with pre-made levels. From the starter menu you can load your own online map by URL or select local files in the splat, ply, or spz formats. A real-time scene adjustment panel lets you line up the virtual bungee platform with your custom environment, and once it looks right you can export that setup as a JSON configuration file to share with others. The game includes dynamic bungee rope physics, air drag, and camera field-of-view effects that change based on how fast you are falling. It is fully translated into English, Simplified Chinese, Japanese, and Korean. Because the game loads large 3D scene files, it cannot be opened directly from your computer's file system due to browser security restrictions. It must be run through a local web server, which the README shows how to set up using Node's npx serve, the VS Code Live Server extension, or Python's built-in http.server module. Controls are simple: move the mouse to look around, press space to jump once the camera is locked, press R to reset back to the platform, and press escape to unlock the mouse and bring back the settings panel. The repository stores its large map files using Git Large File Storage, so Git LFS must be installed before cloning or the actual map data will not download. The README also notes that imported JSON map configurations are only added to a saved maps list and must be manually loaded by clicking a Load button before they take effect. A live demo is hosted on Itch.io.
