About this app

i3dViewer opens 3D models on your phone, with no account, no upload and no internet connection. Tap a file in any file manager and it is on screen. It reads GLB, glTF, OBJ, STL, FBX, PLY and 3MF. Whatever you hand it is converted to glTF on the device itself, keeping the materials, colours, textures and placement the file carried — the colours of a multi-material 3MF print, the vertex colours of a scan, an OBJ's material library, a scene of FBX parts each in its own position. A PLY with no faces is drawn as the point cloud it is. Drag to orbit, pinch to zoom, drag with two fingers to pan, and a mouse works too. Animations play with a scrubbable timeline and a speed control. An axis gizmo says which way you are looking, and a readout gives the zoom and offset. Models can be spun slowly on the spot, shared as a picture, or saved back out as GLB — as they came, or squeezed: medium packs the geometry more tightly, maximum shrinks the textures with it. A whole folder of models can be converted in one go.
