GLB 2.0

GLB is a binary file format representation of 3D models saved in GL Transfer Format (glTF). Information about 3D models such as node hierarchy, cameras, materials, animations, and meshes in binary format. This binary format stores glTF assets (JSON, .bin, and images) in binary blobs. It also avoids the problem of increased file size that occurs in the case of glTF. The GLB file format brings compact file size, fast loading, full 3D scene representation, and extensibility for further development. The format uses model/gltf-binary as the MIME type.
