Will this model run on a phone?
Drop a glTF, GLB or OBJ. It is parsed in your browser by Go compiled to WebAssembly; nothing is uploaded.
Drop a .glb, .gltf or .obj here, or click to choose
How it works
The parser reads the glTF JSON (from a .gltf or the first chunk of a .glb) and sums accessor counts for indices and positions, image sizes and material counts; for .obj it counts faces and triangulates polygons. Budgets: a mid-range phone holds about 300,000 triangles, 50 draw calls and 100 MB of textures in a configurator at 60 frames a second.
