BONUS · Our most recent experiment

Our best approach — 3D Gaussian Splatting

Beyond the established LiDAR + photogrammetry pipeline, our team also explored a state-of-the-art neural rendering technique: 3D Gaussian Splatting (3DGS). From a small set of input photographs, 3DGS produces a photorealistic, fully navigable 3D scene in the browser — preserving real lighting, textures, and even reflections.

Navigation · Mouse + Keyboard

Left drag Orbit / rotate the scene Right drag Pan (slide camera sideways) Scroll wheel Zoom in / out Double-click Focus on the clicked point W A S D Walk forward / left / back / right (FPS mode) Q  /  E Move down / up vertically Shift Move faster while pressed Space Reset / re-center camera

Side toolbar (inside the viewer)

Fullscreen — expand the viewer to the whole screen 🏠 Home view — reset to the original camera 🎬 Auto-rotate — let the camera orbit on its own 🥽 VR / AR — open in immersive mode (if device supports) Quality — toggle render quality / performance Info — scene metadata, author, sharing options

On mobile: one-finger drag = orbit · two-finger pinch = zoom · two-finger drag = pan.
