What is a .glTF file?
glTF is a modern, efficient 3D model format for real-time graphics and the web.
- Did you know
- glTF was released by the Khronos Group in 2015 and is often called "the JPEG of 3D".
- glTF stands for GL Transmission Format, designed by the Khronos Group as an efficient way to deliver 3D scenes to graphics applications and the web.
- glTF 2.0 became international standard ISO/IEC 12113 in 2022, ratified by Khronos as a royalty-free, vendor-neutral specification.
- 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 .glTF file
- Drag a .glTF 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.
