What GLTF and GLB files are

GLTF

glTF (GL Transmission Format) is an open 3D format from the Khronos Group, often called the JPEG of 3D. A .gltf file describes the scene in JSON and can point to separate binary and texture files, and it loads quickly in web viewers and game engines with support for realistic PBR materials and animation.

GLB

GLB is the binary form of glTF, packing a model's scene description, geometry, textures and animation into one file. That makes it easy to share and fast to load, which is why it is widely used for 3D on websites, in game engines and in AR viewers such as Google's Scene Viewer.
