What is a .glb file?

File Extension Details

glTF (GL Transmission Format) is a royalty-free, open standard for 3D scene and model transmission, developed by the Khronos Group. The 'glb' file extension represents the binary file format of glTF. Unlike the ASCII-based '.gltf' format which stores scene information in JSON files and textures/binary data separately, '.glb' packages the entire glTF asset (including JSON scene description, textures, and geometry data) into a single binary file. This makes '.glb' files more compact, easier to transmit, and faster to load. The binary format uses a chunked structure, with a JSON chunk describing the scene and a binary chunk containing the mesh data, textures, and other resources. This structure allows for efficient parsing and rendering of 3D models in various applications, including web browsers, game engines, and 3D viewers. The glTF format is designed to be an efficient, interoperable asset delivery format that minimizes runtime processing and supports PBR (Physically Based Rendering) materials, animations, and skeletal structures.
