GLTF

gLTF, is a open source format. The Khronos Group created this format for 3D web, AR, VR, Games and 3D advertising. GLB the first really well-defined standard for 3D, a compressed binary version of gLTF. This file format supports geometry, materials, textures, colors, and animations. This includes PBR (Physical Based Rendering), so shadows and light will appear more realistic. gLTF is based on JSON, so it stores some data in external files like textures (JPEG or PNG), shaders (GLSL), or geometry and animation data (BIN). GLB files store all this data internally. The Khronos groups is continually improving and updating this file format. It is quickly becoming the standard for 3D shopping.

USDZ
