| Specification | PLY - Polygon File Format | |
| Format features | Supports 3D model geometry, appearance, scene graph hierarchy, and animation. A .gltf file may be self-contained or may reference external binary and texture resources, while a .glb file is entirely self-contained | Amoung with STL, it is one of the most simple formats for storing polygonal information |
