3D Model Viewer

i3dViewer opens 3D models on your phone, offline: no account, no upload. Tap a file in any file manager and it is on screen. It reads GLB, glTF, OBJ, STL, FBX, PLY, 3MF and zip packages, converting them on the device while keeping their materials, colours, textures and FBX animations.Drag to orbit, pinch to zoom, pan with two fingers. Change the background, lighting preset, light direction and exposure; show a wireframe or normals; hide parts; switch to the model's own cameras and material variants. Measure the distance between two points, and see the volume, surface area and size you need for 3D printing.Export to GLB (optionally compressed), STL, 3MF with colours and textures, OBJ in a zip, or USDZ for iPhone, iPad and Mac. Capture high-resolution or transparent PNGs and record turntable videos. Convert a whole folder at once, and on a foldable, half-fold it for a tabletop layout.
