GlTF
3D scene and model file format / From Wikipedia, the free encyclopedia
glTF is a file format for 3D models, 3D scenes, and 3D assets. It is a standard file format that can be read by many programs. A glTF file can have file extensions of .gltf (JSON/ASCII) or .glb (binary). Both .gltf and .glb files may use external resources, such as for images or mesh data. Or, both may have data embedded inside of them (as base64-encoded text in .gltf files or as raw bytes in .glb files).[1][2][3] glTF is an open standard developed and maintained by the Khronos Group. glTF supports 3D model geometry, appearance, scene graph hierarchy, and animation.[2] glTF is intended to be a simple, portable, and compatible format for 3D assets, reducing file size and runtime processing by apps.[2][4] As such, its creators have called it the "JPEG of 3D."[2]
