Open3D vs Vitrine AR

Open3D Viewer is the fastest free 3D model viewer for STL, GLB, OBJ, FBX, STEP, DXF, USDZ, PLY, 3MF, GLTF, IGES, DAE and 3DS files. Open any 3D file in seconds, view it in AR with Apple Quick Look, and check it for 3D printing — no account, no sign-up, no cloud upload. Your files never leave your iPhone or iPad. Whether you're a 3D-printing hobbyist checking an STL before slicing, a 3D artist previewing a GLB or FBX, or a CAD user opening a STEP or DXF, Open3D Viewer opens it instantly — without the paywalls and login screens other 3D viewers force on you. SUPPORTED 3D FILE FORMATS • Mesh: STL, GLB, GLTF, OBJ, PLY, 3MF, FBX, DAE, 3DS, USDZ • CAD: STEP / STP, IGES / IGS, DXF Export & convert Turn OBJ, PLY, 3MF, FBX, DAE, 3DS and more into STL for 3D printing or GLB for sharing. Files save straight to your Downloads folder — no extra apps, no online converter, everything happens on-device. A 3D VIEWER THAT DOES THE BASICS RIGHT • Open files from Files, email, downloads, or any "Open with" menu • Smooth orbit, pan and zoom touch controls • Render modes: solid, wireframe, X-ray, textured, matte • Wireframe overlay — see the geometry on top of the rendered surface • Preset camera views (front, side, top, perspective) • Light and dark themes • 5 background colours + 6 HDRI lighting environments (studio, sunset, dawn, dusk, dark, white) • Play built-in animations • View 3D models in AR via Apple Quick Look (USDZ) • Capture a screenshot or a rotating GIF and share it • Recent files with auto-generated thumbnails • Full model specs: triangle count, vertices, materials, textures, bounding box BUILT FOR 3D PRINTING • Print-readiness check: manifold / watertight detection, overhangs, wall thickness • Bed-fit check for popular printers (Bambu A1, Prusa MK4, Ender 3, Bambu X1C) • Rough weight, filament length and cost estimates • Measure distances on the model • Cross-section / clipping plane to inspect interiors • Scale and resize tool • Convert and export between GLB and STL LOCALIZED The interface automatically follows your device language. Currently available in English, German, Spanish, French, Portuguese, Hindi, Japanese, and Chinese. NO ACCOUNT. NO CLOUD. NO NONSENSE. • No sign-up, ever • 100% on-device. Works offline. • We never read, scan, or upload your files • We don't track which files you open The STL viewer and GLB viewer that makers, 3D artists and engineers actually want: clean, fast, and local. Measurements and print-readiness figures are estimates, not a replacement for a slicer or proper measuring tools. See the in-app Disclaimer.

Vitrine turns 3D files into photoreal AR presentations. Import CAD and 3D files (STL, OBJ, glTF/GLB — including Draco-compressed — and USDZ), drop on physically-based materials, pick studio-grade lighting, and walk your client around the result at true scale through the iPhone or iPad camera. • Import: STL, OBJ+MTL, glTF/GLB (incl. Draco), USDZ/Reality — with automatic repair, welding and smart decimation • Materials: 60+ PBR presets, or apply the file's own materials • Lighting: 15 environments, including real HDR image-based lighting • Configurators: capture states (colors, exploded views) viewers switch with one tap; Auto-Explode builds the exploded view for you • Stories: guided step-by-step walkthroughs — states, viewpoints and your text, paged with arrows in the viewer and in AR • Stage in AR: arrange parts at true scale in the real room and capture the result as a state • Callouts: numbered pins with notes, photos and links — drag them across the model to place them • AR anchoring five ways: tabletop, any surface (LiDAR), printed QR marker (live-tracked) — face and body anchoring return in a coming update • Exhibition mode (Pro): lock a device to curated scenes for fairs and showrooms — passcode-gated exit; Stand Statistics count what visitors actually opened (on-device only) • App Clip (Marque): print a Visitor Link code and anyone can open your scene instantly — no install, hosted on YOUR web space, never ours • LiDAR scanning (Pro), USDZ export (Pro), unlimited projects (Pro) • Ready-made example scenes and models for every AR mode Free to use with three projects and every core tool. One purchase unlocks Pro — no subscription, no accounts, no data collection.
