What is glTF / GLB?
glTF (GL Transmission Format) is an open, royalty-free standard for delivering 3D scenes and models efficiently to the web and real-time engines. GLB is its single-file binary variant that bundles geometry and textures.

glTF vs GLB
glTF can reference external assets; GLB packs everything into one binary file.
PBR materials
glTF carries physically based materials for realistic real-time rendering.
Why glTF won the web
glTF is compact, fast to load and designed for runtime rather than authoring, which makes it ideal for the web and AR/VR.
It is often called “the JPEG of 3D” because of how widely it is supported for delivery.
Getting models into glTF
CAD formats like STEP, IGES and CATIA can be converted to glTF for web display.
Mesh formats like OBJ and FBX can also be converted to glTF / GLB for modern delivery.
