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. 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.
