About GLTF Format

glTF (GL Transmission Format) is the 'JPEG of 3D' — an efficient, open format for 3D scenes and models. Optimized for real-time rendering, it is the standard for web-based 3D content, AR/VR, and game assets.

About GLB Format

GLB is the binary version of glTF that packages 3D geometry, textures, and materials into a single file. It loads faster than glTF for web and mobile 3D applications and is the standard for AR experiences.
