How to use glTF Viewer
- Open a model; for glTF, select local buffers/textures with the .gltf file.
- Orbit with drag, zoom with wheel/pinch and pan with right-drag or two fingers.
- Choose camera/view/units, inspect bounds and download a PNG screenshot.
Example: Select model.gltf, its model.bin and referenced local images together.
Questions
Do models leave my browser?
No. Models, buffers, textures, geometry and screenshots stay local. External glTF resource URLs are blocked; select local companion files together.
Are STL dimensions always millimeters?
No. STL, OBJ and PLY are unitless; choose assumed mm, inches or meters. glTF uses meters and 3MF declares its units.
Is the STL watertight check conclusive?
No. Quantized edge matching is a heuristic, limited to 100,000 triangles. It does not prove watertightness or rule out self-intersections. Volume is shown as an estimate only when this edge check finds no open/non-manifold edges.
