3DGS Viewer

3DGS Viewer is a fast, private, fully offline viewer for 3D Gaussian Splatting scenes. Open your captures straight from your device and explore them in crisp, real-time 3D — no account, no cloud, no internet connection required. Built as a native rendering engine (not a web wrapper), it reads raw splat files directly from memory for instant loading and smooth navigation, even on scenes with millions of splats. WHY YOU'LL LOVE IT • Truly offline & private — no servers, no sign-in, no tracking, no data collection. Your 3D files never leave your device. • Broad format support — uncompressed .ply and .splat, plus compressed .spz (versions 1–4) and .sog. • Fast GPU rendering — WebGPU compute accelerates splat sorting where available, with automatic WebGL2 fallback on older devices. • Crisp, artifact-free edges — a custom viewing system removes the spiky shapes that ruin straight lines on balconies, railings and buildings. • Handles huge scenes — open multi‑million‑splat models with an adjustable Splat Limit to balance detail and performance. • View-dependent color — optional spherical-harmonics rendering (SPZ v4) for richer reflections and highlights. • Walk mode — move through your scene in first person. • Capture & share — save high-resolution photos, or record turntable and cinematic flythrough videos (MP4/H.264) straight to your Photos library. • Level & orientation tools — straighten a tilted scene or flip it right-side up in one tap. • Battery & thermal aware — the render loop eases off during static viewing to reduce power draw. OPEN FILES THE EASY WAY (iOS) Tap Open File and pick from Apple's Files screen — it shows every provider you have (On My iPhone/iPad, iCloud Drive, Google Drive, Dropbox, and more). ONE-TIME PURCHASE — NO SUBSCRIPTIONS, NO ADS Pay once and own it. Every feature is included — no subscriptions, no ads, no in-app purchases, and no data collection. PERFECT FOR Photogrammetry and 3D-scanning enthusiasts, real-estate and architecture visualization, VFX and research workflows, and anyone who wants to view Gaussian Splat captures on the go — completely offline.
