What is a .GLB file?
GLB is the single-file binary version of glTF, bundling geometry, textures and animation together.
- Did you know
- GLB is the packaged form of glTF, the Khronos 3D format released in 2015.
- GLB is the binary container for glTF 2.0, packing a JSON description chunk and a raw binary buffer chunk into one self-contained file.
- glTF 2.0, and with it the GLB packaging, was adopted as international standard ISO/IEC 12113 in 2022.
- What Analyser shows you
- View STL, OBJ, PLY, OFF, STEP, IGES, BREP, 3MF, AMF and glTF/GLB models in an interactive WebGL viewer with orbit, orthographic or perspective projection, a wireframe topology overlay, an orientation cube, triangle count, bounding box, surface area and volume. glTF 2.0 and binary GLB scenes are parsed natively - the node graph is flattened, mesh geometry shown, and the authoring tool, version and mesh/material/animation counts read. STEP/IGES/BREP are tessellated with OpenCASCADE and STEP shows its originating CAD system, version and AP203/214/242 protocol; 3MF and AMF let you inspect each model and assembly on the build plate individually, and any pictures a 3MF package carries - its own thumbnail, the build-plate renders slicers such as Bambu Studio and OrcaSlicer write, and texture maps - are extracted and shown with it. Wavefront material libraries (MTL) are broken out into each material with its colours, shininess, opacity and the texture files it references.
- Open a .GLB file
- Drag a .GLB file onto the Analyser home page (or tap to pick one). It opens entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
